Charmy is an immature, fun-loving kid. Hyperactive and beebrained, he loves to play and can be seen buzzing around everywhere. However, he is also very friendly, lighthearted and cheerful. He also loves to prank around, like when he annoyed Vector for being wrong, and is rather gullible, having an easy time to quickly forgive and forget, as seen by how he was the first to befriend Dr. Eggman after he had seemingly had turned over a new leaf due to amnesia while the rest of his team remained apprehensive.
