How about Sakuria puts everyone in their canonical tiers. So Palutena is goddess tier, Kirby is god tier, and Samus is actually fast and nimble like in her games (and has all her beams)...
Then Shulk would dominate everyone, followed by Palutena, Ganondorf and Ness.
The Monado is serious shit, Palutena's a goddess, Ganondorf only gets done in by a Master Sword to the face, and Ness gets a fuckhuge powerup part way through his game that basically lets him solo everything up to Giygas if he wanted to. I don't even know what PK Rockin' is supposed to be because I stopped paying attention lmaoooooo
Oh shit, throw Rosalina in that tier too because she's also basically a space goddess.
I would think the tier below that is Kirby, Pit/Dark Pit, Bowser, Mr. Game and Watch (he turns into a fuckhuge octopus and can apparently manipulate dimensions as he's a 2D being in a 3D world) and Mewtwo if we're including him. Probably the Mario Bros. and the princesses too. I don't know if we can include Samus at this level or the one immediately below it, to be honest.
Next is Link/Toon Link, ZSS, Captain Falcon, the other Pokemon, Wario, and the Kongs.
I don't feel like organizing everyone else.
At the lowest would probably be Olimar's weak ass self and maybe Wii Fit Trainer, because even though she's basically a nonhuman yoga instructor she can apparently harness the power of the sun.
