Split personalities of good and evil with both having direct control of the mind, has insane power, but the two halves have to argue about anything before they act, so most of the power is rendered moot.

Well, that's kind of the gist of Mmetuta. Mmetuta has a different power for each emotion, but they're constantly arguing about what do do. Rage is fire, Avarice is magnetism (haven't fully worked that out yet), Fear I'm working out, Willpower is force, Hope is Healing, Compassion is Pressure, and I haven't worked out Love yet.
