|“You say I'm a Ninja for the day, call me . . . the Purple Ninja!”|
|— Lil' Nelson to the Ninja|
Lil' Nelson is the honorary Purple Ninja of the Ninja. He broke both of his legs while rigorously training to be a Ninja, but eventually they healed. He later got a job as a paperboy, becoming friends with Antonia in the process.
Dareth arranged for the Ninja to visit Lil' Nelson and make him an honorary ninja for a day. The Ninja stopped by on their way to stop Clouse, remembering their lesson to "not put off what can be done today." However, due to Kai's addiction to his fans, he alerted them about their location and ended up being surrounded.
A fellow fan himself, Lil' Nelson dons a hand-made gi, becomes the Purple Ninja, and helps the Ninja by blocking the fans so they can escape to the roof. Lloyd expresses his gratefulness in his assistance, but Lil' Nelson says that he is grateful his wish was granted, thanks to Lloyd and the Ninja.
On his first day of delivering newspapers, Nelson wakes up early and gets ready quickly, even before his mother woke up herself. Just as he was about to leave on his bike, his mother gives him his helmet. Putting it on, he leaves for Ninjago City.
Lil' Nelson made a cameo in a flashback during Zane's message delivering a newspaper.
Lil' Nelson is Antonia's dance partner in Vlad Tutu's class. He and the rest of the class watched in awe as Jay showed off his moves.
When Lil' Nelson gets a chance to play, he is able to reach level 13, but disappears into the game when he actually enters Prime Empire.

In Season 6, Nelson wears a self-made purple gi and has leg casts, due to his injuries.

- In earlier drafts, Nelson was going to appear in "Day of the Departed," but according to Tommy Andreasen his part was taken out. Lil' Nelson even appeared in the Rock Roader set despite not appearing in the special.
- In the Rock Roader set, he had an actual Spinner game card. The card was Kendo Cole.
- He is the third honorary Ninja to appear in the series, after Dareth and Skylor.
- Despite being restrained to a wheelchair due to his injury, he developed impressive ninja-like techniques in moving around that impressed even the Ninja.
- His legs have long since healed by the time of Season 11.
- It is also shown that aside from his legs, he also once broke his entire body, arm, skull, and once lost a tooth. This strongly indicates he is incredibly accident-prone.
- He has grown and is the first character to have mid-legs (posable short legs introduced by LEGO in 2018) in the show.
- This is yet to be represented by a physical minifigure.
- He lives in the same village the Sons of Garmadon attacked in "Big Trouble, Little Ninjago" and most likely the same one Harumi and her birth parents lived in before moving to Ninjago City as revealed in "Samurai X-Treme."
- He got a job delivering newspapers and became friends with Antonia on his first day.
- Nelson could be seen in Gayle Gossip: A Closer Look entering Prime Empire. He is seen several times throughout Prime Empire, always among a crowd.
- Lil' Nelson's name is based off of Nelson LaMonica, the Ninjago Brand Director.
