Most OPed/Broken character(s) in VG history?

[The Fury]

Asuka from Tekken, not because she is quick or has amazing attacks, just that one counter move stance. (Back + Throw), she can be in the middle of a combo you blocked entirely, then you instantly counter only for you to be in a throw because she can pull it off that quickly apparently and it's near impossible to get out of.

Okay so not that OP but for Tekken standards it is.
