So I wanna do Void, but I'm having trouble coming up with Powerset ideas, any thoughts?

Ooh! I have a few! 
-Objects disappear from reality temporarily. Like, he touches a locked door and it disappears for five seconds, then reappears, still on its hinges. May or may not work on self/people.
-Drain life force from creatures.
-Store objects in a pocket dimension. Like an inventory in an RPG. 
-Your dude holds out their hand and a sphere appears in it. Things the sphere touches disappear.
-An aura around swords. Swords with the aura don't cut things so much as they erase things the blade touches from reality.
