Shamrock was a Marvel Comics heroine, making her first appearance in 1982's Marvel Super Hero Contest of Champions, a series which introduced a whole slew of international superheroes, each packed with more cultural stereotypes than the last. Shamrock, for example, was Molly Fitzgerald. She had good-luck powers, her da was in the IRA, her brother - Paddy - was killed in an IRA bomb blast, and, although you can't see it, under her green shamrock costume she's got flaming red hair. Also, she Irish Irish McIrish blah blah Irish. Happy drinking!
