Best known as the iconic mascot of Disney. In-universe, he's outgoing, plucky, and willing to lend a helping hand. There are times where his sense of mischief gets the better of him, however.
He's picked up a variety of skills over the years. As a trained Keyblade Master, he wields the dark realm's variation of the Kingdom Key, and can cast various light spells and high-level magic. He's also practiced with Yen Sid's magic paintbrush, channeling paint and thinner alike through it (thinner only affects paint-made things).
