>>95893542Donald is cool in KH.
He's always 100% focused on his mission, he's the straight man that keeps Goofy in check, and at one point he seriously considers leaving behind Sora when the keyblade picks someone else.
He does the right thing eventually but it takes some convincing and a set of circumstances.
Mikey tells him to do something, and by god the fucking sticks to it and sees it trough to the very end.
In terms of abilities he's also a pretty damn powerful and fearsome mage by the end of the games.
KH's Donald is in no way a bastardization of the character, it still definitely feels like him, he's just very sobered up and focused on his task at all times.
It's like a "grown up" version of him.
