The four major feats people list for Palpatine:
1. He drained an entire Planet.
Right, except he never drained an entire planet, but an unknown amount of energy from one over several different points of time to slow down his rate of aging.
2. He drained billions of beings.
Right, except he never drained billions of beings, but an unknown amount over several different points of time for the same reason listed above.
3. He lifted the Lusyanka, and mindwiped millions.
Right, except these assertions at best are logical speculation, with no real basis in fact.
4. He can summon force storms.
Right, which is completely useless in a close ranged battle scenario, and which is ritualistic in nature, that doesn't draw off of Palpatine's power, and actually grants him control over them.
Yeah, that guy sure is one hell of a pimp.
