Squirrel Girl can beat Thanos in The Avengers 2. She's one of the strongest characters in the Marvel Universe. She's also hilarious. She needs to have her own movie, or at least an appearance in Iron Man 3 or one of the other upcoming Avengers universe sequels. Tell Marvel to get it done.
Dear Marvel,
We want Squirrel Girl to be added to the Marvel Movie Universe. She has beaten Thanos in the comics, and thus would be a valuable asset to The Avengers team. Though we prefer a movie, we would settle for a series of cameos, similar to The Black Widow.
Thanks for your cooperation.
