What type of energy are Boom-boom's time bombs? Crushing or Energy?
"generate explosive charges as streamers of raw energy or in the form of "time bombs", solid spheres of contained concussive power that she can psionically levitate, defuse and detonate on a delayed time cycle"
That's her entry from uncannyxmen.net about her powers. I guess you could give her energy damage with high knockback? Or maybe just concussive would be good, just like Cyclops.
I have both her and Cyke at crushing power and i think it's the best option. It's just that something her powers are depicted as explosions tht generate heat especially in the Netxtwave run
