Groot

Groot is a fictional character from Marvel's Guardians of the Galaxy. He is a sentient, tree-like being with the ability to regenerate, grow, and control plant matter. Groot communicates primarily by saying "I am Groot," which both he and others interpret based on context and tone. Despite his limited language, he displays loyalty, kindness, and strength, often acting as a protector of his friends. His unique physiology allows him to absorb sunlight and nutrients to fuel his regenerative powers. Groot embodies themes of growth, self-sacrifice, and the importance of teamwork within the Marvel universe.
