Irma is a patriotic, working class police officer with a bit of a propensity for aggressive tactics (and lethal, radioactive force). She is married to Ron, a precog whose abilities prevent him from gaining employment for most of the series. They have two children Cherry Bomb and Cerebra.
She was partner and a close friend to Girl One until her death and is then partnered with Joe Pi. Her grief over Sung Li’s death makes her acceptance of her new partner very difficult but they eventually become friends.
Five years after the Ultima incident, Irmageddon is briefly paired with Rexa Smax.
