First fight: Asajj Ventress vs Pre Vizsla

Note: Pre Vizsla can use his gadgets and fight dirty, as he did against Maul.

Second fight: An unarmed Rex, Appo, Fives, Echo, and Jesse vs an unarmed Ventress. First one to be knocked out loses.

Third fight: An unarmed, unarmored hand to hand fight between Din Djarin and Rex.

Bonus round: Ventress Vs the Grand Inquisitor

Note: The setting is the same as in the Tales of the underworld episode, just swap the unidentified inquisitor to Marrok, or for the bonus round with the Grand Inquisitor.
