Groot, the sentient tree-like being, Guardians Of The Galaxy member and Rocket Raccoon's trusty aid, is far more formidable than you might think he is based on how he looks and acts (he's a real sweetheart). Most notably, he boasts extreme levels of super-strength and durability - to the extent that he can manhandle hulking alien beings with consummate ease. He can also manipulate his own body is various useful ways, such as expanding his limbs to a length that enables him to pick up large groups of enemies and smash them off walls, forming protective shields for himself and others and growing and regenerating new body parts. In fact, his cuttings can be used to regrow entire new bodies, as was the case at the end of Guardians Of The Galaxy. He also had the power to emit spores that provide light, which was used to guide him and his team-mates in darkness.
