Hot Wheels Battle Force 5 S01E12 - Double Down

A stormshock anomaly causes the BF5 to enter a battlezone that contains their opposites: the evil BF5.  As both sides fight "themselves" for control of the battlekey, Vert gets captured by his evil doppelganger.  Evil Vert dons Good Vert's red shock suit and sneaks back to Earth, pretending to be one of the good guys.
