Overpowered abilities, attacks, moves, perks, etc. that have made a game too easy

Not so much against human players but in most fighting games grappler characters usually can easily destroy the AI. Zangief makes makes most of the challenges in SF4 very easy, just spam lariat. In Persona 4 Arena score attack is ultra hard but with Kanji it's a joke. And even the near impossible Unlimited Mars mode in Blazblue is made kind of reasonable with Tager.
