Playable Characters that are better than the MCs

Been playing Hyrule Warriors Definitive and dear god is Linkle the most busted character in this game. Her crossbows are insanely quick, have a wide range, and melt boss gauges. Her pegasus boots are also great but not quite as busted.

Are there any characters in games that seem like they shouldn’t be as op as they are? Preferably ones that aren’t supposed to be Main Characters or the Villains(if they’re unlockable).
