|“Whoa, that's cool.”|
|— Chopper Maroon|
Chopper Maroon, as well as a shorter biker (possibly Nails) went to the movie theater to find Ultra Violet. He was also one of the bikers who was thwarted by Samurai X when bullying kids in the street.
He was one of the two Sons of Garmadon members who guarded the captured Cole, only for him to be tricked and knocked out by Cole during his escape.
Chopper Maroon was watching the captive Ninja as baby Wu jump on his back for enjoyment. Later, Ultra Violet left him in charge to watch after the Ninja, only for him to be tricked by Cole again, while baby Wu frees the Ninja and they knock him out. Later, he escaped with all of the Sons of Garmadon and captive Lloyd in tow on the Destiny's Bounty.
Chopper Maroon, along with Mohawk, was tasked with patrolling the grounds of the Royal Palace, which was reconstructed into the Temple of Resurrection. After their patrol, they guarded the entrance to the temple until they were knocked out by the Ninja while they were distracted by Harumi performing the ritual to resurrect Lord Garmadon. They were both arrested by the Ninjago police force and sent to Kryptarium Prison for their crimes.
Now an Sons of Garmadon Police Officer, he, along with Mohawk, let the captured Dareth go because he isn't on the list of people to catch.
He is at the Radio station with Ultra Violet when The Resistance arrive, tieing him up.
Now freed, he joins the ambush on the base of The Resistance alongside Mohawk, fighting the members present.
Chopper Maroon is present with Ultra Violet and Killow at Lord Garmadon's throne.
Chopper, Mohawk, and another biker harass Gayle Gossip and a cameraman until Dareth arrives, warning them that he is the Brown Ninja. As one of the bikers makes a joke, Dareth says they twisted his words, before attempting to attack, only to slip up, go flying and take out all three bikers, landing on top of Chopper Maroon and knocking him unconscious. Later, He runs to Kryptarium and warns them that the Ninja are back. The Elemental Masters then break out. Chopper Maroon was later arrested and sent back to Kryptarium as a prisoner after Garmadon's defeat.
