And now may I present to you...

                                  S u p e r n o v a

...who can create a huge, blindingly bright explosion that will  blind evildoers (temporarily of course, since he's a superhero not a supervillain) and/or totally destroy any physical objects that are causing a hazard to good honest citizens (especially hazardous objects put there by supervillains).

However, after doing so all that will be left of him will be a large expanding cloud of gas and debris.
So obviously he hasn't ever used this superpower.

His nemesis is a supervillain who goes by the name of S h r a p n e l and who can turn his body into deadly shards that fly out in all directions wreaking havoc.
Once.
Obviously he's never used his superpower either.

Supernova and Shrapnel have had many long standoffs.

And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
