- “Arcadia is a hotbed for supernatural activity. There's a whole other world that we don't know anything about. Creatures lurking in the shadows...monsters living among us. Whatever they are, someone or something in Arcadia is at the center of this.”
- ―Eli in the teaser for part two.
Eli Pepperjack is a boy who often get bullied by Steve Palchuk and is trying to prove the existence of supernatural activity.
Not much is known about Eli's background, but it would seem that he has been bullied and known about the other realms for quite for sometime.
Eli is first seen getting shoved into a locker by the local jock, Steve Pulchuk after he claims to have seen some "mythical creatures" last night. When Jim comes to Eli's defense, Steve challenges him to a fight, which Mr. Strickler breaks up, but Steve is still willing to fight later.
Discovering the Trolls
One night while sleeping, Eli sees Blinky, AAARRRGGHHH!!!, and Bular running right by, which proves the did see the trolls outside of his house, and sets out to prove that they exist.
One night, a mailman arrives at Eli's house, delivering a package of spy gear to him (possibly to use for helping him prove he was right about the trolls). He then sees a smashed goblin outside of his house and takes a photo of it on his phone. When he shows it to the kids on a field trip, Toby takes the phone, sees the photo and quickly deletes it, destroying Eli's evidence.
Sometime after Jim, Claire, and their friends defeat Bular, the spring dance starts coming up and Jim, Eli, and Steve are nominated for prom king. They compete for a theme for the dance. Steve comes up with a luau theme, Eli comes up with an 80s theme, and Jim accidentally comes up with the idea of moles. Jim's theme is the winner.
A couple of days later, Eli competes against the other nominees in a contest on who can hold their hand onto a truck the longest. A couple of hours later, when the teacher leaves, Eli is put in charge of keeping the peace between Jim and Steve, who start fighting. Eli wins the competition since he never took his hand off of the truck.
It is implied that Eli will have a bigger role in part two.
Eli has black hair. He wears a green t-shirt, light brown cargo shorts, white socks, big blue glasses and black trainers. Once, during the Romeo and Juliet play, Eli sported a beret in his role as the narrator.
Eli is aware of the existence of troll life after he witnessed Blinky, AAARRRGGHH!!! and Bular run by his window, but no one believes him when he tries to tell them. Throughout the series, he tries to get more proof of the Trolls' existence, but usually ends up losing all his evidence or gets beat up by Steve or any of the other jocks. He really wants to be Jim's best friend, but often fails, due to Jim's secret double life and the fact that no one reaches out to him.
- Eli's appearance is reminiscent of Jim's from the original books.
- Eli's personality is reminiscent of Jim's father from the books.
