Hulk's able to resist mind-control due to the dual+ nature of his personality. IIRC, he did so against Xavier in WWH and as with his other powers, his resistance scales with his rage/butthurt.

it's irrelevant seeing as Sidious likely wouldn't get the chance to use that power. If he isn't successful at cutting off Hulk's head or removing limbs, his next option will be force push/lighting and that won't do a damn thing to Hulk except piss him off more.
I'm not familiar with Sidious in the EU, has he ever used mind control to stop someone from attacking him? I don't recall him doing so in the movies.
He used it to wipe the memories of billions to trillions (population density of Coruscant makes anything less impossible) to shroud the burial of his personal Super Star Destroyer.
He used it on Galen Marek too, but he snapped out of it.
He can also rip the surfaces off of worlds, tear entire fleets apart, disintegr8 matter and he drained a paradise world of life and will over the course of years, turning the populace into his mindless slaves.
There are a ton of other overpowered characters as well.
