Mad Moxxi

Mad Moxxi is the host of the Colosseum matches in The Underdome in the second DLC, Mad Moxxi's Underdome Riot.

Background
She has been married at least three times to different husbands. She created The Underdome to keep her occupied until she finds herself a new husband. She is also a part of the storyline in The Secret Armory of General Knoxx. She has at least two children, Scooter (her unseen daughter) and Scooter (her son named after her daughter). She also might have a slight crush on lilith according to what she says.
 * Mr. Shank from The Secret Armory of General Knoxx was said to be her first, and she later said he was her second, contradictory to the intro to the Underdome Riot DLC, where the second husband was hinted to be Steve.
 * Her third husband was Marcus Kincaid. She was also involved, at least sexually, with Lucky Zaford according to Scooter, but there is no indication as to whether or not he was one of her husbands.

Secret Armory of General Knoxx
In The Secret Armory of General Knoxx, she is part of the main quest line. As you find out more about her, you find out she is Scooter's mother. She sends you on a mission to deal with her first husband, known as Mr. Shank.
