10 Guest Party Members We Wanted To Stick Around Forever

10. Riku - Kingdom Hearts

Playing as Sora makes seeing Riku at any point in the entire Kingdom Hearts series feel more than a little weird, because the guy is still your best friend, even when he's sort of an evil shadow creature who might want to murder every one on sight.

This is at its most complex when you see your silver-haired friend-slash-attempted-murderer in the belly of Monstro the whale, while you're hanging out with Pinnochio. Despite the fact you and Riku are on weird terms at this point - because of his whole "will I give in the the dark side and become a serial killer" thing - he still opts to help you out in the fight against the Parasite Cage boss, even healing you if you need it.

Unfortunately, Riku does opt out of being a good guy, meaning when you see him doing sketchy stuff later, you can't help but feel a pang of nostalgia for the good times you guys had in the stomach of a whale.
