Julie Finster, aka 84

 Last name listed as Howard but later is Finster. First name witness protection for her family? Maybe use Howard as last name during college in order to have a life outside of the "biz".

Maybe related to Thaddeus Boomer, aka Mister Extraordinary?

Family isn't well off. Her costume is "steel wear" and not the kind with self cleaning molecules.

Future team as outlined by Tyler:
Steel Sentinel on as a heavy blaster, male,
Uplink; tech and tinkerer female,
Hat Trick; magical type, variable power sets, female, just temping on the team right now,
Crusade; flying heavy hitter, male, and
Alterity; speedster, male."
