Squirrel Girl’s famous victory over Thanos belongs to Marvel comics, not the MCU. It is associated with GLX-Mas Special #1, but the encounter is not shown as a detailed fight, so the exact way she won is not established by the available account.
Was Squirrel Girl’s victory over Thanos in the MCU?
No. The feat is from the comics; the sources for it do not show Squirrel Girl defeating the film-universe Thanos. The MCU wording in the question is a common point of confusion, not the setting of the encounter. Marvel’s Squirrel Girl profile lists GLX-Mas Special #1 among her essential reading. Thanos also has a separate comics history, including the Infinity Gems and the Infinity Gauntlet, as summarized in Marvel’s Thanos profile.
How did Squirrel Girl defeat Thanos in the comic?
The comic is associated with the result, but the fight itself is not presented as a detailed sequence. That means there is no well-supported account of the precise tactic Squirrel Girl used. In particular, it is not established that a swarm of squirrels is shown defeating Thanos.
Could she have used her squirrel abilities?
Marvel’s character profile says Doreen Green can communicate with squirrels and may enlist nearby animals to distract or fight opponents. Those are general abilities, not verified details of this specific encounter. The profile does not establish that squirrels were involved in the Thanos victory.

What is known about the issue’s date and the Watcher?
The issue’s year is inconsistent in the available references: Marvel’s profile gives 2006, while secondary discussion calls it 2005. Without confirmation from the issue’s indicia or a reliable issue record, it is safer not to assign a publication year.
Secondary discussion also reports that Uatu the Watcher confirms the defeated Thanos is genuine. That panel detail has not been verified against the comic here, so it should be treated as a reported claim rather than a confirmed fact.
