Neptune and Sora from Kingdom Hearts would make an interesting pair. Neptune's carefree and fun - loving nature could contrast well with Sora's more heroic and determined personality. They could go on an adventure together, with Neptune showing Sora the wacky and unique aspects of the Gamindustri world while Sora teaches Neptune about the different Disney - inspired worlds he has visited.
Well, Gateau could be paired with a tough, no - nonsense character. Gateau's flamboyant style and the other character's more serious demeanor would create a great dynamic.
