Give me Bandana Waddle Dee or give me death. I BELIEVE
Okay, but seriously. With Kirby being tied for my favourite Nintendo franchise with Pikmin (Sad Alph alt days), Kirby's best friend is easily my most wanted, and part of the reason is because I have a bit of a bias towards spear users, though I would love if he could mix it with his parasol and other things.
Of course, I have other wishes. Phoenix Wright in particular is up there, but he'd be a great bonus for me. For others, I have Rayman, Captain Toad, Bomberman (Sad AT days), Lycanroc, and various Kirby side characters. (Galacta never. Sad costume days.) But really, if Bandana Dee is in, I genuinely could not care less as to who else gets added.
