Ep. 19: Evil Empress Roll! (Part 2)

19

Roll is on a rampage, disobeying Maylu and beating MegaMan to a pulp. Higsby reappears before it's too late and informs Maylu that the "Devil" chip will be negated if another chip is inserted. Thus, Roll returns to normal, but she's too damaged to continue in the tournament. (Source: Wikipedia)
