Groot

He is Groot, a flora colossus from the branch world of Planet X capable of manipulating plant matter and regrowing his damaged body from a single splinter. The hero at the heart of the Guardians of the Galaxy, Groot may not have many words to say, but his actions always speak for themselves.

Groot accompanied Star-Lord and Rocket on a scouting mission to Klyntar, where they became stranded after their ship was shot down. Klyntar's dark king, Knull, now seeks to corrupt Groot's regenerative powers in an effort to cultivate the ultimate symbiote.
