|Portrayed by:||Andrea Martin|
|Only Appearance:||Make 'Em Laugh|
Lisa Lorraine was a stand-up comedian turned into Mighty Mom (or Rolling Pin) by the Joker.
Lisa Lorraine was a comedian and actress, who served as a judge to the "Laff-Off" comedy competition. One of its contestants was given the hook for failing to register for the competition. That contestant, actually the Joker in disguise, swore revenge.
One year later, Lorraine's agent set her up with judging the "Laugh-Off" again. But before she could attend it, the Joker surprised her with a home visit. He sedated her, and with Mad Hatter's mind control technology, turned her into Mighty Mom.
Whereas Joker used the other judges – Buddy Standler and Harry Loomis simply to ruin their careers, he used Lorraine as muscle when he took over the Laff-Off. Robin managed to subdue her and remove the mind control patch.
As Mighty Mom Lisa's personality wasn't that far from her regular behavior, except for a habit of talking like an exaggerated version of a housewife, which had been akin to a sitcom Lorraine starred in where she played a gruff housewife. When the patch came off Lisa responded with a slap to Robin's face before reassuring him she was back to normal.
- "Mighty Mom" being based on a TV show as a hard-nosed housewife dealing with a unruly kids and a blue-collar husband was most likely a reference to the sitcom Roseanne.
