A couple months previously, I had created PhatLady, a sonic/sonic defender. She too was a shielder, offering resistive shields (foes hit as often, but with less damage). I liked playing her a lot, and wondered if I could duplicate the experience with a defensive shielder (foes hit less often, but with full damage). It turned out, I could. :)
Sonic offered both a protective set and a blast set, but Force Field just has the protective set. So I tried to pick the blast set that was the most force-fieldy. Radiation Blast is not an exact corolary, but it was the closest I could come to it. I mean, what if you allowed your shieldy stuff to leak strategically?
He was not my first character to join the Circle of Elemental Power super group, but he may have been the one to team with them the most. They were a good and active group of folks.
Having been a reactor operator (on a nuclear sub) in real life, it was kind of fun coming up with his science-fictiony look. Real nuclear folks would be wearing something drab, like bluish grey coveralls. That said, I'm pretty sure that one of the capsules on his belt holds a TLD.
