"I am Groot."
Groot is an alien plant-creature and member of the Guardians of the Galaxy from Marvel Comics; the original version of the character appeared in Tales to Astonish #13 as a villain, while a heroic version appeared in Annihilation: Conquest - Starlord #1. This version of Groot went on to achieve worldwide fame for his role in the MCU films, starting with Guardians of the Galaxy.
A member of the flora colossi race, Groot is most known for his limited vocabulary, usually only able to say the phrase "I am Groot." A friend of the bounty hunter Rocket Raccoon, Groot met Star-Lord, Gamora, and Drax the Destroyer while pursuing the Power Stone sought by the Mad Titan Thanos and his ally Ronan the Accuser. Bonding over their outcast status from the intergalactic community, the group formed the Guardians of the Galaxy, seeking their fortunes while also helping those in need.
Groot will appear with the other Guardians in Disney vs. Comics, battling against the forces of evil.
