Has Minerva ever been consistent? Seems like she's something almost entirely different every time.
This is also the problem with Batman, Punisher, and any of the really talented but utterly mundane beings in a super powered world. You occasionally have to let them do something ridiculous once and awhile to make them valuable. (I mean, why hasn't anyone hired someone bullet proof to go up on Punisher? There are almost no super powered beings in Gotham which seems downright absurd given the plethora of them everywhere else).
