Companion Cube

The Companion Cube is a fictional object from the video game series "Portal." It appears as a weighted companion cube that players must use to solve puzzles. Unlike regular in-game items, the Companion Cube is anthropomorphized, featuring heart-like designs, which evoke feelings of attachment and empathy. As players navigate through challenges, the cube assists them and ultimately becomes symbolic of friendship and sacrifice within the game's dark humor. Its significance highlights themes of companionship and the emotional connections players can form, even with inanimate objects, within a virtual environment.
