IF he has "only" the power/reality/space gems, I don't think anything short of low tier abstract is gonna do jack crap to him.
Having said that, Anomaly or In-betweener can do it. Both of them are immune to the effects of the gems.
Also unless there's been a retcon, anyone that can BFR him into another universe can do it too. It's been said the gems only work in the universe they are native to.
It also depends on how good Hood is at using the gems. Considering he had Power and Space when he beat the crap out of Rulk, logically, if he tapped into the full power of the gems, he should have killed him. And I have a feeling Hood's not going to be extremely proficient with the gems, so that could effect how things go down through the arc.
