First Appearance: Tales to Astonish (vol. 1) #13 (Nov 1960)
Abilities: Groot has the power to control other trees, increases his mass (i.e, "sprout") and appears invulnerable to fire. He has also regenerated his entire body from just a small twig. Groot is known for just saying "I am Groot!" and nothing else. It's been conjectured that there are multiple meanings of that phrase depending on how and when Groot says it.
Chances he's in the movie: 99%
Lowdown: Seemingly another member of the team who is the last member of their race, Groot's abilities should not be underestimated. He's helped save the universe on numerous occasions. Rocket Raccoon is Groot's current BFF and the duo should be the comic relief of the big screen "Guardians."
