Guardians of the Galaxy Groot

Groot is a sentient, tree-like creature who is a frequent accomplice of the intergalactic criminal Rocket Raccoon. Together, the pair traveled the galaxy on bounty hunting missions until they met Star-Lord, who convinced them to help him sell the Orb for a huge amount of money. However, when the Orb was revealed to be one of the Infinity Stones that Ronan the Accuser is after, Groot convinced his friends to risk everything to stop Ronan from destroying Xandar. During the battle, Groot sacrificed himself to save his new friends. However, part of his destroyed body was planted in a pot by Rocket, after which it grew into a new Groot, now called Baby Groot, after which they joined the Guardians of the Galaxy.
