The series, hosted by Joel McHale, features a cast of reality television's most memorable and notorious villains.

Contestants live in a house while competing in challenges for power and safety, voting to banish each other until the last villain remaining wins a $200,000 cash prize and the title of America's Ultimate Supervillain.

The villains build alliances, scheme, manipulate, and backstab as they are eliminated one by one until only one remains and is crowned America's Ultimate Supervillain.

Carole Baskin, Abby Lee Miller, Spencer Pratt, Ben Robinson, and Danielle Staub made guest appearances during the first season.

At the start of the episode, eliminated contestants (with the exception of Bobby) returned to the house and it was revealed that the winner of the season would be determined by a jury vote.

The winner of the Battle Royale Challenge would automatically make it to the finale, joined by the contestant they did not nominate on the Hit List.
