|“So you can't lie, huh? Oh! You pee in a swimming pool?”|
|— Luke to Cole|
Luke was one of the Sons of Garmadon that infiltrated the Borg Tower. He was the one that accidentally triggered the alarm, and was ultimately left behind by Mr. E in order to escape from Lloyd. He was then arrested by the police.
When Cole accidently mixes up the regular tea and the Tea of Truth, it causes him to utter the truth instead, causing Luke ask him ridiculous questions as well as to get more information about the Ninja. Later, they then set off for a Sons of Garmadon hangout Luke accidentally mentioned.
Prior to "Dread on Arrival," Luke was released from custody. As he was patrolling the grounds of the Temple of Resurrection at the Royal Palace, he discovered some scuba gear. As he was about to inform one of the generals that there are intruders on the premises, he was knocked out by Nya and dragged behind a bush. He was presumably found and arrested by the police.
Luke was freed from Kryptarium Prison by Harumi and the newly-resurrected Lord Garmadon. After turning the prison into a bunker, Luke served as a lookout near the prison entrance, observing Lloyd and notifying the rest of the Sons of Garmadon of the Green Ninja's approach.
Luke and another guard listen to Killow talking before Harumi tells them to keep an eye out. Killow suddenly feels like doing karaoke due to a Mind trick from Neuro. Later, at Laughy's as Luke watched Killow sing, they're interrupted by Lloyd's speech and immediately head back to Borg Tower.
He is ordered by Killow to catch Mistaké. When he asks why, as she is just an old lady, Killow replies she is so much more. Luke goes to get her, but finds nothing but a rat running from the room. He returns empty handed.
Despite not appearing in the episode, Luke was presumably arrested following Emperor Garmadon's defeat and sent back to Kryptarium.
In Ultra Violet's story, the Sons of Garmadon were fighting Lloyd and Nya.
Luke is a member of the Sons of Garmadon, a ruthless biker gang devoted to its mysterious leader, the Quiet One. Determined to steal the powerful Oni Masks, the Sons of Garmadon may be the most dangerous threat the ninja have ever faced.
- His Ninjago.com page and description were deleted a few days after they got published for unknown reasons.
- His hairpiece is from another LEGO theme called Exo Force. However, it was only released in green, and Luke's is white with a black strip.
- In sets, Luke wears black shoulder pads and black biker helmet, but in series he lacks both.
- Because of that, Luke looks like Skip Vicious in the sets, but in the series, it is revealed that they have different hairpieces.
- His face looks somewhat like Jay's before Season 8, because he has a notch in his right eyebrow too.
