GROOT

GUARDIANS OF THE GALAXY is a superhero science fiction film based on the Marvel Comics. The hero has stolen a mystical orb once which indeed contains immeasurable power called an Infintiy Stone. He has intended to sell the orb but later protected it from the villain instead with his companions. One of the companions is a tree-like humanoid called GROOT which is also my favorite characters in this film. Although it seems weak and clumsy, as it just knows two dialogues which are "I am Groot." and "We are Groot." and the branches are vulnerable, I think it is the most powerful hero in both attack and defense in flexible alteration. Be strong or weak depends on our own attitude and mind.
