Lakewood Plaza Turbo
K.O. v.s. Graffiti Wiener
K.O. starting a power battle.
When K.O. realized who the graffiti wiener was that vandalized the plaza sign, K.O. stepped out into the plaza and initiated a power battle, something he had tried to do earlier, but failed. After a crowd gathered, K.O. explained that he knew that the graffiti wiener was a Boxmore spy. While possibly not done intentionally, Radicles appeared to be the opponent, up until K.O.'s Power-Fist Fireball veered around Radicles and hit a suspicious, hooded man, who was revealed to be Darrell.

Carol v.s. Chameleon Sr.
Carol starting a power battle.
Carol calls upon a power battle between the two when Chameleon Sr. insulted K.O., which results in the two battling. Carol grabs Chameleon Sr. by the tongue and starts to repeatedly punch him while pulling him back to her when he falls back, however Senior pulls his tongue back which makes Carol slam her into the roof. Chameleon Sr. then gloats about how she is a coward, however, unbeknownst to him, she grabs his tail, spins him around, throws him into the air, then kicks him back down onto the roof. While Carol tells K.O. that her work is done, Senior breaks out of the rubble and grabs her with his tail and throws her onto the parking lot. While Carol is laying in the crater, Chameleon Senior does a belly-flop onto her. He grabs Carol and continues to fling her around in his tail. The battle ends when K.O. tries to offer him some Dragon-Dragon Burritos, but to no avail, Chameleon Senior eats K.O., who drops the burritos down his stomach, and fills Senior's mouth with fire. K.O. escapes and pulls off Chameleon's suit.
