Sadly, the list doesn't include Giorno (though Giorno with GER could definitely whoop Goku's butt).

My list includes: Doppelganger Schezo, Doppelganger Arle, Poison Ringo and Rafisol from Puyo Puyo (it's a puzzle game series, look it up), Zero, Omega, the Stardroids, Shadow Man, Vent, Aile & iCO from Mega Man, Kirby (obviously), Dark Sakura, Saber Alter, Red Arcueid, Gilgamesh, BB, Tsukihime Arcueid and Archer from the TYPE-MOON universes, Yami Bakura & Pharaoh Atem from Yu-Gi-Oh, Rimuru Tempest from That Time I Got Reincarnated As A Slime, Storyshift Chara & XGaster from Undertale, Rera from Samurai Shodown, DevilArtemis Universe Cell, and Fire Sonic from Super Mario Bros. Z.
