Groot is a tree-like alien humanoid from the Planet X. He was a former bounty hunter, alongside Rocket, and became a member of the Guardians of the Galaxy. In the movie, he is voiced by Vin Diesel. He was later reborn into a new "Groot", when Rocket picks up a stick of Groot and puts it into a pot full of dirt. He is best friends with Rocket, the only one who actually understands him.
- "I am Groot."
- "We are Groot." (Groot sacrifices himself for his friends).
- Groot is often referred as “Flora Colossus."
- This may be because he is a tree which is a plant-like structure of nature and moreover is very resilient, quite colossal.
