So many levels of fail here, though I particularly like the police giving a supervillain his superweapon BACK because, despite it having no apparent controls "They've deactivated it".... (Probably the same techs who installed Indigo, the 25th century android, with limiters that guaranteed her loyalty and ensured she couldn't kill again.. and we remember how THAT turned out)
The supervillain team is memoraly awful, and the the only positive spin I can put on this whole thing is the notion that, on first reading this, I thought he meant the Catwoman Angle Man was supposed to be the pre-Crisis Angle Man, whose last space-time re-angling sent him there without his weapon or at least burned it out. Thus there are two of him, the suave Wonder Girl one who WAS kind of cool, and has the angle weapon, and this one, who remembers fights that could now never have happened (but did in HIS past), and now has no powers.
