He got Power and Space from Reed and the Inhumans, respectively, and just barely beat Iron Man and the gang to the punch for Reality. It looks like Thor w/Time Gem and Rulk are about to fight him next issue of Avengers.
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.
Afaik hood lost all access to dormammus powers and that's why he had to get help from Loki... And now the gems
