Groot resembles a sentient tree from Planet X and descended from a race of walking flora. He is a member of Marvel’s group of intergalactic superheroes Guardians of the Galaxy. His communication skills are limited, but he’s a very loyal and caring friend, and most importantly, a valuable member of the group. “I am Groot!” is his catchphrase and are the only words he says. Groot’s sweet and helpful nature became clear when he created a protective shield with his body to protect his friends. Groot was eventually restored back to life and joined his superhero-friends again.
