An Astrophysics themed power set might be cool...
drop a temporary singularity that collects enemies and crushes them
quantum tunneling as a short range teleport
graviton nova - pushback
throw a singularity that drags enemies away from you and collects them as it flies along its path
graviton fist - force bolt
static field - arcs to random enemies around you
superposition - projects clones or decoys of you
pulsar - drops a mini neutron star that spins and beams everything around it with EM damage
kuiper event - drop a comet on someone you don't like
This would be sort of a hybrid combat and crowd control set ... others would like you clustering bad guys for their AOE attacks.
A Flying set maybe? - set built around enabling you to effectively fight mobs while in flying mode
strafe - you fly by blasting a line with smg fire
claw - grab a target, lift and drop it on others, causing smash damage to everyone
slice - fly through enemies doing lethal damage to everyone in a line
whirlwind - circle enemies, taunting and debuffing to-hit for a while
divebomb - crash down from high delivering a blastwave on landing
