Animation has always been capable of more than Saturday morning morality plays, yet for decades it was boxed into a cultural assumption that cartoons were only for kids. R-rated animation exists because artists, filmmakers, and audiences pushed back against that limitation, using the medium to explore violence, sexuality, politics, satire, and psychological complexity with a freedom live-action often can’t match. When cartoons grow up, they don’t just add profanity or bloodshed; they expand the language of cinema itself.
The R rating matters because it represents a line crossed intentionally, whether through graphic imagery, transgressive humor, or thematic depth that challenges comfort zones. From underground counterculture experiments and foreign imports to studio-backed provocations and cult classics, these films reflect shifting attitudes toward censorship, artistic freedom, and what animation is allowed to say about the world. They often arrive as lightning rods, banned in some countries, re-rated after release, or misunderstood on arrival before later being reclaimed as essential works.
This list isn’t about shock value alone, but about impact, ambition, and evolution across decades and continents. The greatest R-rated animated films earn their status by embracing the medium’s limitless potential while refusing to sanitize adult experience, whether through brutal realism, biting satire, or existential unease. In ranking them, we’re tracing how animation stopped asking permission to be taken seriously and instead demanded a seat alongside the most daring films ever made.
Defining the Ranking: Criteria, Cultural Impact, and What ‘R-Rated’ Really Means
Before diving into the films themselves, it’s worth clarifying how this ranking was shaped and why the R rating carries such weight in animation. Unlike live-action, where adult classification is common, animation still earns that label through deliberate provocation or ambition. These films don’t just cross a line; they redraw it.
What Qualified a Film for This List
Every entry here received an R rating from the MPAA or an equivalent adult classification internationally, whether for graphic violence, explicit sexuality, pervasive language, or deeply disturbing themes. That rating had to be integral to the film’s identity, not a technicality or a marketing gimmick. In other words, the content demanded maturity, rather than simply indulging in it.
Artistic intent mattered as much as intensity. The films selected push animation forward through visual innovation, narrative daring, or tonal audacity, using adult material to deepen meaning rather than distract from it. Shock without substance didn’t make the cut.
Cultural Impact Over Pure Controversy
While many of these films sparked outrage or censorship battles, controversy alone was never the goal. The highest-ranked titles changed how audiences, studios, or entire industries perceived animation’s potential. Some influenced future filmmakers, others helped legitimize adult animation in regions where it was dismissed outright.
Cult longevity also played a role. Several entries were commercial failures or critical punching bags upon release, only to be reassessed years later as foundational works. Their staying power, quotability, and continued relevance speak louder than opening weekend numbers ever could.
A Global Perspective on Adult Animation
This list treats R-rated animation as an international language, not a Hollywood niche. Japanese anime, European art-house features, and underground American productions often approach adult material differently, shaped by distinct cultural taboos and censorship systems. A film rated R in the U.S. might be considered routine elsewhere, or vice versa.
By weighing regional context alongside impact, the ranking avoids flattening global animation into a single standard. What matters is how boldly each film used its freedom within its own system, and how far it pushed the medium as a result.
What ‘R-Rated’ Really Means in Animation
In animated cinema, an R rating is rarely about realism alone. It often signals emotional extremity, moral ambiguity, or satirical venom that would lose potency if softened. Animation can visualize the unfilmable, exaggerate the grotesque, and externalize inner trauma in ways live-action cannot safely or affordably attempt.
The greatest R-rated animated films don’t just earn their rating; they justify it. They prove that adulthood in animation isn’t defined by excess, but by honesty, risk, and a refusal to dilute complex ideas for mass comfort.
A Brief History of Adult Animation: From Underground Counterculture to Prestige Cinema
Adult animation did not begin as a respected cinematic category; it emerged in the margins. Long before studios viewed animation as a viable medium for adult storytelling, artists used it as a weapon of satire, provocation, and rebellion. These early works were often screened in midnight theaters, film co-ops, or passed hand-to-hand on bootleg tapes, far from mainstream approval.
The Underground Origins
In the United States, adult animation’s roots trace back to the countercultural explosion of the late 1960s and 1970s. Films like Ralph Bakshi’s Fritz the Cat shattered the illusion that animation was inherently juvenile, pairing cartoon visuals with explicit sex, racial satire, and political anger. Its commercial success, and the backlash that followed, proved there was an adult audience hungry for animated films that spoke directly to the chaos of the era.
Elsewhere, adult animation evolved with fewer commercial constraints. European animators, particularly in France and Eastern Europe, treated animation as an extension of art cinema, embracing eroticism, existentialism, and philosophical abstraction without apology. These films rarely chased ratings; they challenged censors by default.
Anime and the Normalization of Mature Themes
Japan took a radically different path. Adult-oriented animation was never segregated into a novelty category, but integrated into the broader film and home video market. By the 1980s and 1990s, anime regularly tackled war trauma, cyberpunk alienation, sexual identity, and body horror with a seriousness Western studios avoided.
Films like Akira and Ghost in the Shell demonstrated that animation could handle adult subject matter with scale, sophistication, and technical ambition. Their international success reshaped global perceptions, proving animated films could compete with live-action science fiction and philosophical cinema on equal footing.
The 1990s and the Rise of Satirical Extremes
As cable television loosened content restrictions, adult animation surged into mainstream visibility. MTV, late-night programming blocks, and indie distributors embraced animation that was abrasive, vulgar, and intentionally confrontational. This era produced films that leaned heavily into shock, but also sharpened animation’s satirical edge.
While not all of these works aged gracefully, they expanded the boundaries of what animated films could say and show. Importantly, they also normalized the idea that adults could seek animation specifically for its irreverence and cultural critique.
From Cult Provocation to Critical Legitimacy
By the 2000s and 2010s, adult animation began shedding its reputation as a gimmick. International festivals increasingly programmed animated features alongside live-action dramas, and critics evaluated them by narrative ambition rather than novelty. Films addressing grief, political collapse, and psychological trauma earned serious awards consideration, reframing animation as a prestige storytelling form.
Today, R-rated animated films occupy a unique space. They retain the freedom of their underground origins while benefiting from global distribution and critical legitimacy. The greatest examples bridge that history, proving that animation’s most radical act was never shock itself, but insisting it deserved to grow up.
The Definitive Countdown: Ranking the 20 Greatest R-Rated Animated Movies of All Time
With animation finally unshackled from the expectation of family accessibility, these films represent the medium at its most fearless. The following rankings balance cultural impact, artistic ambition, historical importance, and how powerfully each film uses its R rating to explore terrain live-action often cannot.
This countdown spans continents, decades, and styles, reflecting how adult animation evolved from provocation into one of cinema’s most expressive storytelling forms.
20. Felidae (1994)
A murder mystery starring cats sounds whimsical until Felidae plunges into graphic violence, fascist allegory, and existential dread. Its R rating is earned through unflinching brutality and philosophical pessimism that feels closer to noir horror than animal fantasy. The film remains a cult shocker for viewers unprepared for its darkness.
19. Sausage Party (2016)
Crude, confrontational, and unapologetically obscene, Sausage Party weaponized computer animation to dismantle consumer culture and religious belief. Beneath the shock humor lies a surprisingly pointed satire about ideological control. Its box office success proved R-rated animation could thrive commercially in the modern era.
18. Heavy Metal (1981)
A landmark of Western adult animation, Heavy Metal fused sci-fi fantasy, sexuality, and rock culture into a kaleidoscopic anthology. While uneven, its visual ambition and uninhibited excess defined a generation’s understanding of animated films made strictly for adults. Its influence still echoes through genre animation today.
17. Belladonna of Sadness (1973)
More art installation than conventional narrative, this erotic folk-horror film uses psychedelic imagery to explore sexual trauma and patriarchal violence. Its explicit content was inseparable from its political fury. Once banned and marginalized, Belladonna is now recognized as a radical feminist landmark.
16. Fritz the Cat (1972)
The first animated feature to receive an X rating in the United States, Fritz the Cat shattered taboos with sexual explicitness and racial satire. Ralph Bakshi’s anarchic style captured the chaos of 1970s counterculture. Its historical importance alone secures its place here.
15. The Plague Dogs (1982)
This bleak adaptation of Richard Adams’ novel uses animation to confront animal experimentation and human cruelty. Its emotional devastation far exceeds its understated presentation. Few animated films are this relentlessly despairing, making its adult rating feel almost merciful.
14. Mad God (2021)
Phil Tippett’s stop-motion nightmare unfolds like a descent through hell rendered in clay and decay. Dialogue is nearly absent, replaced by pure visual horror. Mad God exemplifies animation as physical endurance art, punishing and hypnotic in equal measure.
13. Vampire Hunter D: Bloodlust (2000)
A gothic sci-fi epic drenched in elegance and melancholy, Bloodlust refined anime’s ability to blend violence with romantic fatalism. Its lush visuals and operatic tone elevated genre animation beyond pulp. The R rating enhances its tragic atmosphere rather than overwhelming it.
12. Anomalisa (2015)
Quietly devastating, Anomalisa uses stop-motion realism to explore depression, alienation, and emotional numbness. Its adult rating stems not from violence, but from psychological intimacy and sexual frankness. The film proves maturity in animation can be painfully subtle.
11. Ninja Scroll (1993)
Few films define anime excess like Ninja Scroll, with its graphic combat and grotesque villains. Yet beneath the carnage lies disciplined craft and mythic storytelling. It introduced countless Western viewers to anime’s unapologetically adult potential.
10. South Park: Bigger, Longer & Uncut (1999)
What could have been a novelty cash-in became one of the sharpest political musicals ever animated. The film’s R rating is worn proudly, using profanity to satirize censorship, war hysteria, and moral panic. It remains as incisive as it is profane.
9. Waltz with Bashir (2008)
An animated war documentary was once unthinkable, but Waltz with Bashir shattered that assumption. Its R rating reflects emotional trauma rather than explicit violence. The film’s fusion of memory, guilt, and animation reshaped nonfiction cinema.
8. Perfect Blue (1997)
Satoshi Kon’s psychological thriller dissects fame, obsession, and identity with surgical precision. Its disturbing imagery and fractured narrative demand adult engagement. Perfect Blue’s influence stretches far beyond animation, shaping modern psychological horror.
7. Akira (1988)
Few films announced animation’s adulthood as loudly as Akira. Its apocalyptic scale, political paranoia, and body horror earned its R rating and global reputation. Decades later, its technical ambition remains staggering.
6. Ghost in the Shell (1995)
Philosophical, atmospheric, and quietly devastating, Ghost in the Shell uses animation to question consciousness and identity. Its adult themes unfold with intellectual rigor rather than shock. The film’s legacy permeates science fiction across all media.
5. The End of Evangelion (1997)
An emotionally brutal conclusion to a cultural phenomenon, this film weaponizes animation to explore depression, annihilation, and self-loathing. Its violence is inseparable from its psychological collapse. Few animated films are this confrontational or personal.
4. Persepolis is excluded due to rating

1. Perfect Blue
Satoshi Kon’s masterpiece remains the gold standard for adult animated cinema. Its R rating is not a gimmick, but an essential tool for exploring identity collapse, voyeurism, and psychological terror. Perfect Blue stands as definitive proof that animation can be as harrowing, sophisticated, and artistically essential as any live-action film.
Sex, Violence, and Satire: How These Films Earned (and Challenged) Their Ratings
R-rated animation has never been about shock alone. What unites the greatest examples is how deliberately they use adult content to interrogate power, desire, trauma, and societal collapse. In many cases, the rating wasn’t merely earned—it was wrestled into existence by films that refused to soften their vision for the sake of comfort or convention.
Sex as Psychological Weapon, Not Cheap Provocation
In films like Perfect Blue, Belladonna of Sadness, and Fritz the Cat, sexuality is inseparable from control, exploitation, and identity erosion. These works deploy sex not for titillation, but as a destabilizing force that exposes systems of abuse, voyeurism, and hypocrisy. The R rating becomes a necessity, allowing animators to confront adult realities that live-action often sanitizes or aestheticizes.
Japanese adult animation in particular reframed sexual content as existential horror. Perfect Blue’s most disturbing moments aren’t explicit acts, but the psychological aftermath, where consent, performance, and reality blur beyond recognition. The rating protects the film’s honesty, not its excess.
Violence That Leaves Scars
Violence in R-rated animation tends to linger longer than its live-action counterpart. Akira, Ninja Scroll, Vampire Hunter D: Bloodlust, and Mad God make physical destruction feel mythic, grotesque, or spiritually corrosive rather than exhilarating. Bloodshed is animated with intention, forcing viewers to sit with its consequences rather than cheer its spectacle.
War-centric works like Waltz with Bashir and When the Wind Blows challenge ratings boards by presenting violence that is restrained but emotionally devastating. Their R ratings stem not from gore, but from moral weight, political anger, and the refusal to offer comforting resolutions. Animation becomes a medium for memory, guilt, and generational trauma.
Satire That Cuts Too Close
If sex and violence earn the R rating, satire often dares the censors to intervene. South Park: Bigger, Longer & Uncut and Sausage Party weaponize vulgarity to dismantle moral panic, consumerism, and performative outrage. Their profanity and explicit humor are inseparable from their critique, exposing how easily societies conflate offense with danger.
Heavy Metal and Felidae similarly push boundaries by embedding adult themes within genres traditionally dismissed as juvenile. By combining graphic imagery with social commentary, they challenge the assumption that animation should be safe, moral, or reassuring. The R rating becomes a badge of defiance, not decadence.
Global Standards, Global Rebellion
One of the most striking patterns across these films is how differently cultures define what’s unacceptable. European animated cinema often earned restrictive ratings through sexual frankness and political provocation, while Japanese films were flagged for existential dread and stylized brutality. American entries, meanwhile, frequently clashed with ratings boards over language and satire rather than imagery alone.
Together, these films expose the subjectivity of censorship itself. The R rating becomes less a moral judgment and more a historical artifact, reflecting the anxieties of the era and culture that attempted to contain these works. In challenging their ratings, these films expanded not just what animation could show, but what it was allowed to mean.
Beyond Hollywood: International R-Rated Animation That Redefined the Medium
While American studios often framed adult animation through satire or shock, international filmmakers treated the R rating as a license for artistic reinvention. Across Japan, Europe, and Latin America, animation became a vessel for political fury, sexual transgression, and psychological horror in ways live-action cinema often couldn’t safely attempt. These films didn’t just push boundaries; they rewrote the grammar of animated storytelling.
Japan’s Existential Shockwaves
Few films loom larger over adult animation than Katsuhiro Otomo’s Akira, a seismic work whose R rating stemmed from graphic violence, body horror, and apocalyptic nihilism. Its influence on cyberpunk, blockbuster pacing, and visual density is immeasurable, proving animation could rival live-action spectacle while surpassing it in thematic ambition. Akira didn’t ask to be accepted as adult cinema; it demanded recognition.
Mamoru Oshii’s Ghost in the Shell took a colder, more philosophical approach, earning its R rating through nudity, violence, and its disquieting interrogation of identity and surveillance. Where Akira explodes outward, Ghost in the Shell turns inward, using animation’s precision to visualize abstract questions about consciousness and state power. Its legacy echoes through modern sci-fi, from The Matrix to contemporary AI cinema.
Psychological Horror and the Unreliable Mind
Satoshi Kon’s Perfect Blue remains one of the most unsettling R-rated animated films ever made, not because of excess gore, but because of its ruthless psychological realism. Sexual violence, obsession, and fractured identity collide in a thriller that weaponizes animation’s ability to collapse reality without warning. Its influence on directors like Darren Aronofsky underscores how animation can access mental terror with unmatched intimacy.
Europe offered its own confrontations with the psyche. Felidae, often misremembered as a children’s film due to its anthropomorphic cast, earns its R rating through graphic violence and disturbing philosophical themes. Its bait-and-switch aesthetics challenge the viewer’s assumptions, reinforcing how animation can smuggle adult horror into deceptively familiar forms.
Sex, Power, and Political Transgression
Belladonna of Sadness stands as one of the most controversial animated films ever produced, its R rating driven by explicit sexual imagery and its unflinching portrayal of abuse and female rage. Yet its painterly, experimental style reframes eroticism as both weapon and protest, aligning sexual transgression with political rebellion. The film’s cult revival has cemented it as a landmark of feminist animation.
From Latin America, films like The Wolf House extend the tradition of political allegory into nightmarish territory. Its R rating arises from sustained psychological dread rather than explicit content, using stop-motion decay and visual instability to confront authoritarian trauma. The film exemplifies how international animation often earns restrictive ratings by unsettling the soul rather than assaulting the senses.
A Medium Unchained by Borders
What unites these films is not provocation for its own sake, but a shared refusal to simplify adulthood. International R-rated animation embraces ambiguity, despair, eroticism, and moral compromise as essential truths rather than taboos. In doing so, these works expanded animation’s cultural legitimacy, proving that maturity in the medium isn’t defined by shock value, but by the courage to confront what audiences would rather avoid.
Controversies, Bans, and Cult Status: How Censorship Shaped These Films’ Legacies
R-rated animated films rarely arrive quietly. Many of the genre’s most revered titles earned their reputations not just through artistic daring, but through clashes with censors, moral watchdogs, and rating boards unprepared for animation that refused to behave itself. In several cases, controversy became the very engine that transformed these films from niche provocations into enduring cult landmarks.
When Ratings Boards Didn’t Know What to Do With Animation
In the West, the MPAA’s discomfort with adult animation has historically resulted in harsher scrutiny than comparable live-action films. Fritz the Cat, the first animated film to receive an X rating in the United States, became a cultural flashpoint precisely because its sex, drugs, and political satire violated the assumption that cartoons were inherently harmless. The rating didn’t kill the film; it turned it into a countercultural phenomenon.
Decades later, South Park: Bigger, Longer & Uncut faced repeated threats of an NC-17 rating due to its profanity and gleeful sacrilege. The filmmakers’ strategic cuts and reversals exposed how arbitrary censorship standards could be, especially when animation amplified vulgarity through exaggeration. The resulting R-rated release became one of the most commercially successful animated films ever, proving controversy could be box-office fuel.
International Bans and Cultural Misreadings
Outside the U.S., censorship often took more extreme forms. Belladonna of Sadness was effectively buried in Japan for decades, its explicit sexuality and political fury deemed too transgressive even within an industry known for experimentation. Its eventual rediscovery through international festivals reframed it not as exploitation, but as a foundational work of feminist and avant-garde animation.
Felidae suffered a different fate, frequently marketed as a children’s film in Europe despite its graphic violence and philosophical nihilism. Broadcast edits and parental backlash followed, turning the film into a cautionary tale about aesthetic misclassification. That confusion ultimately contributed to its cult status, as audiences sought out the uncut version to experience the film as it was intended.
Cuts, Compromises, and Creative Resistance
Some films survived only through compromise. Akira’s original U.S. release carried an R rating and suffered from awkward dubbing and minor edits, muting its political complexity for Western audiences. Later restorations and re-releases allowed the film’s full scope to be appreciated, solidifying its influence on cyberpunk cinema and adult animation worldwide.
Heavy Metal faced bans and restrictions in multiple countries due to its sexualized imagery and violent fantasy, yet its segmented structure made it uniquely resistant to censorship. Viewers traded tapes, quoted scenes, and passed down fandom like contraband. The film’s legacy is inseparable from its reputation as forbidden viewing.
Cult Status as a Second Life
For many R-rated animated films, censorship didn’t end their stories; it delayed them. Midnight screenings, bootlegs, festival revivals, and home video releases allowed these works to find audiences willing to meet them on their own terms. The sense of discovery, of accessing something once deemed off-limits, became part of the appeal.
Over time, what was once labeled obscene, dangerous, or inappropriate has been reassessed as culturally essential. These films didn’t just survive censorship; they were shaped by it. Their legacies stand as proof that adult animation’s most lasting power often emerges from resistance, not approval.
The Legacy of R-Rated Animation: Influence on Modern Adult Cartoons and Animated Cinema
By the time censorship battles cooled and home media normalized access to uncensored cuts, R-rated animation had already done its most important work. It shattered the assumption that animation was a genre rather than a medium, and proved that illustrated worlds could grapple with sexuality, politics, trauma, and moral ambiguity as directly as live-action cinema. What followed was not imitation, but absorption, with its DNA spreading quietly across television, indie film, and international animation.
From Taboo Features to Prime-Time Provocation
Modern adult cartoons owe an enormous debt to films like Heavy Metal, Fritz the Cat, and Akira, even when they appear tonally distant. Shows such as South Park, BoJack Horseman, and Rick and Morty adopted the lesson that animation could be confrontational, profane, and emotionally brutal without sacrificing wit or visual invention. Their freedom to swing between comedy and despair exists because earlier films took the heat for doing it first.
Crucially, these series normalized the idea that adult animation didn’t need to justify its existence through shock alone. The R-rated pioneers proved that explicit content could serve theme and character, not just provocation. That philosophy reshaped how networks, streamers, and audiences evaluate animated storytelling aimed at adults.
Influence on Visual Language and Genre Experimentation
The visual ambition of R-rated animated cinema has been equally influential. Akira’s kinetic cityscapes and fluid action set a new benchmark for animated realism, directly shaping Western sci-fi animation, video games, and even live-action blockbusters. Meanwhile, films like Perfect Blue and Belladonna of Sadness demonstrated how animation could visualize psychological collapse, erotic obsession, and interior states that live-action struggled to depict.
This legacy is evident in contemporary animated films and series that blur genre boundaries without apology. Adult animation today freely mixes horror, noir, fantasy, autobiography, and political allegory because earlier R-rated works refused to stay in a single lane. Their willingness to alienate some viewers in pursuit of artistic clarity remains a guiding principle.
Global Ripples Across Animation Industries
Internationally, R-rated animation helped legitimize adult-oriented production pipelines outside children’s entertainment. In Japan, the success of films like Akira and Ghost in the Shell reinforced the viability of adult anime as a global export. In Europe, cult rediscoveries of films such as Felidae and La Planète Sauvage encouraged arthouse animation that embraced bleak themes and philosophical storytelling.
These films also reshaped festival culture, where animated features began competing seriously alongside live-action dramas. The assumption that animation was inherently lightweight eroded as programmers and critics recognized the medium’s capacity for transgressive, intellectually demanding work.
Redefining What the Rating Represents
Perhaps the most lasting legacy of R-rated animation is how it reframed the rating itself. Rather than functioning as a warning label, R became a signal of creative intent, indicating work unconcerned with mass appeal or comfort. For many filmmakers, earning that rating was not a byproduct but a statement.
Today’s adult animated cinema exists in a landscape built by these risks. Whether through streaming-era features, experimental indie projects, or boundary-pushing series, modern creators are operating in a space carved out by films that endured bans, cuts, and moral panic. The influence of R-rated animation is not confined to specific titles; it lives in the freedom to animate anything at all.
Final Take: What the Greatest R-Rated Animated Films Say About Animation’s Future
Taken together, the greatest R-rated animated films do more than shock or provoke. They prove that animation is not a genre or a demographic, but a storytelling language capable of carrying the same emotional, political, and philosophical weight as any live-action medium. These films earned their rating not through excess alone, but through intent, using violence, sexuality, and moral ambiguity as tools rather than spectacle.
Animation’s Most Honest Storytelling Lives Outside Comfort Zones
What unites these films across decades and continents is a refusal to soften difficult truths. From dystopian violence and erotic obsession to existential dread and social collapse, R-rated animation has consistently explored ideas that demand discomfort. In doing so, it has often reached a level of emotional honesty that mainstream animation avoids.
This willingness to alienate some audiences in order to speak clearly to others is not a flaw, but a defining strength. As long as animation continues to be judged by its perceived accessibility, its boldest works will exist on the margins. The films on this list embraced that position and reshaped it into a badge of credibility.
The Medium Is Expanding Faster Than Its Perception
Technological advances and streaming platforms have removed many of the financial and distribution barriers that once limited adult animation. Independent creators now have access to tools and audiences that earlier filmmakers could only imagine. Yet the influence of classic R-rated animated films is still deeply felt in how modern creators approach tone, subject matter, and visual experimentation.
What has not fully caught up is public perception. While adult animated series have found mainstream acceptance, feature-length animated films aimed squarely at adults remain rare. The continued reverence for these R-rated classics highlights a gap between what animation can do and what studios are still willing to fund.
The R Rating as a Creative North Star
For the greatest films discussed here, the R rating was never the goal, but it became a defining signal. It told audiences that these stories would not dilute their themes for comfort or consensus. In an era where algorithms reward familiarity, that clarity of purpose feels increasingly radical.
As censorship debates, cultural shifts, and global storytelling collide, the future of adult animation will likely mirror its past: controversial, uneven, and fiercely necessary. The next wave of R-rated animated films may look different, but they will inherit the same mandate to push beyond what animation is “supposed” to be.
Ultimately, the greatest R-rated animated movies endure because they treat animation as a serious art form, capable of confronting adulthood without compromise. Their legacy is not just a list of unforgettable films, but a roadmap for where animation can go when it stops asking for permission.
