The Oni Chopper is a huge bike that belongs to Killow. It has a Grundle paint job and a saw blade instead of a front wheel, as well as blades on the sides that swing out to destroy foes. It is the largest bike in the ranks of the Sons of Garmadon.
In order for Snake Jaguar to become a Son of Garmadon, he would have to complete the initiation race. Killow rode in this race and used his Oni Chopper to do so. Early into the race, Harumi told Killow that Snake Jaguar was one of the ninja. Killow then tried to knock his enemy out of the race. He used the bike for the duration of the race.
After the bug on the Destiny's Bounty caused it to crash, Killow and the other two generals lead a team to intercept the ninja and reclaim young Wu. They raced throughout the jungles of Primeval's Eye until they came to a ravine. Killow used the Oni Mask of Deception to move rocks to create a bridge for them to get across. They later faced Samurai X in her mech, who was trying to buy the ninja more time. Using the mechs swords she swiped multiple bikers away, until Killow engaged her with the Oni Chopper, firing from his cannons at her. Despite the Samurais efforts, the Sons Of Garmadon made it to the Bounty, before they could contact Lloyd and tell him that Harumi was the "Quiet One." The ninja were then captured.
Killow uses his Oni Chopper to pursue the Destiny's Bounty.
Killow uses the Oni Chopper to help Mr. E track down Lloyd and the rest of the resistance. It was tipped over by Karlof as the Resistance escaped.
Killow rides his Chopper to track down Skylor after she copied Garmadon's power. He Later rode it towards the Colossus, until Skylor took control of it. Killow sent cars at the stone beast, but it deflected them down onto him and his bike, trapping them as the Mask of Deception broke in half.
