The Serpoians are male-only aliens who clone themselves; according to the official DanDaDan character profile, they target human females to regain reproductive organs. Their abduction of Momo also triggers the awakening of her hidden psychic powers, making their first encounter the event that gives her a way to fight back.
Who are the Serpoians?
The official DanDaDan anime character profile describes the Serpoians as a male-only alien group that increases its numbers by cloning. It gives their motive for targeting human females as an attempt to regain reproductive organs. This is fictional story lore, not a claim about real extraterrestrial life.

Why do the Serpo aliens target Momo?
Momo becomes a target because she is human and female, matching the Serpoians’ stated motive. The profile also connects her abduction to the awakening of hidden psychic powers. The alien attack is therefore not just an early threat: it sets off Momo’s transformation into someone able to resist the dangers she encounters.
How does the first encounter fit the opening story?
The setup begins with Momo and Okarun holding opposite beliefs: Momo believes in ghosts but not aliens, while Okarun believes in aliens but not ghosts. In the MBS series synopsis, they visit a UFO hotspot and a spiritual hotspot to test those beliefs. That collision introduces the series’ supernatural and extraterrestrial world.
#1 Best Overall
Disney+’s episode listing identifies Momo’s psychic awakening in season 1, episode 2, “That’s a Space Alien, Ain’t It?!” The listing is regional catalog metadata and may vary by market. The official profile supports the abduction-to-awakening connection; the episode listing adds the anime’s placement and title.
What other Serpoian details are in expanded coverage?
Spoiler caution: Details beyond the core opening-arc explanation come from secondary coverage and may reach beyond an anime-only viewer’s current point. ORICON’s Japan Anime News profile, last modified November 20, 2024, describes the Serpoians’ psychokinesis as “Rokkon,” surveying technology, communication cables used for merging, and a later Serpoian character, Serpo No. 6 (Rokuro). These specifics are not part of the brief official character profile, so treat them as expanded lore rather than the essential explanation of why the aliens target Momo.

Where can readers find more official series lore?
For a broader reference, Shueisha lists Dandadan Daizukan, an official guidebook by Yukinobu Tatsu published August 4, 2025. Its print edition is listed at 230 pages and includes character explanations, profiles, ability parameters, previously unpublished settings, and 22 pages of new manga. It is an optional guide to the wider series, not a prerequisite for understanding the Serpoians’ role in Momo’s first encounter.
