Julian is a soft-spoken but eccentric student who claims to love everything creepy, gruesome, and deadly. He speaks with a slight English accent, usually either in a shaky and soft voice or in a distressed and dramatic manner, sometimes ending a sentence with a spooky giggle. He talks with his whole body, so to speak, gesturing and posing and waving his hands nearly every word he says. He doesn't seem to know what others think of him, still being actively friendly to Randy and Howard and not bothering to rein in his eccentric behaviour. He acts as a leader to Der Monster Klub, wanting to help his friends feel like they have power over their bullies, though sometimes goes to extreme measures to get what he wants. He doesn't seem afraid of danger at times, staying rather calm while imprisoned in the Land of Shadows, but other times is extremely frightful and nervous.
Role in the series
Julian's first major appearance is in "Tale of the Golden Doctor's Note". He is in Randy and Howard's gym class, and after Coach Green announces they'll be climbing a rope while being pelted with dodgeballs, is one of the students clearly distressed by the situation. He appears later hanging upside down in a locker, having eavesdropped on Randy and Howard's conversation about a Golden Doctor's note that could get them out of gym class. He promises to know the way there, opening a pizza box with a map scribbled inside on how to find the "Old Gym". The three of them discover the entrance by pressing the unused soap dispenser, and shortly Julian finds a conveyor belt type deathtrap, going into a monologue of how death and torture devices are "so cool". Once the trap activates and Julian gets caught on the top level and nearly crushed by a spiked rolling plate, he screams that death isn't cool, causing Howard to call him out for lying. Julian shuts down, curling up on the ground and seemingly in his own world for the time being, at which point Randy and Howard decide to ditch him. When he comes to he panics at being left alone in a scary place and gets stanked by The Sorceror. His stanked form, looking somewhat like a spider but with his tailcoat and hat still on, attacks Randy and Howard. They try and fight him off, and he ends up ripping out or eating most of the Golden Doctor's Notes before being defeated and turned back to normal when Randy punches a hole through his hat. They finally return to the school and the next gym class Randy reveals he gave Julian the last doctor's note since he helped give them the map and because Howard could climb the rope anyway. Julian is seen giggling in the bleachers, but gets hit by a stray dodgeball anyway and knocked backwards.
In "30 Seconds to Math" he appears briefly, first meditating backstage and then going onstage to play a musical piece on a theremin before being knocked over by a tomato.
"Der Monster Klub" is the second episode where he has a larger part, where Randy and Howard are forced to sit with Julian and his group of friends (Theresa Fowler, Juggo, and Accordion Dave) at lunch. He and his friends have formed a small club called "Der Monster Klub" where they play a game that involves choosing the imagined gruesome fates of their worst bullies. They seem to have fun with Randy and Howard for a while before Julian brings up how he thinks students turn into monsters and Randy corrects him, which makes him decide to shout his friend's embarrassing secrets to the cafeteria to turn them into monsters so they can truly get revenge on their bullies. Randy becomes the ninja and tries to fight them, but Julian begs him to let them have their vengeance. When he won't let up, Randy ties him to a chair, which only irritates him and causes him to become a monster as well. Randy tries to fight them all, finding them in the gym with all their bullies rolled up in a giant spider web, and once he destroys the die they use to play their game, they all turn back to normal. Randy asks if Julian remembers how students get stanked, and when Julian gets it wrong Randy seems relieved and smokebombs away.
In "Stanks Like Teen Spirit" its revealed that Julian is on the chess team.
In "McFear Factor" Julian's biggest fear is apparently a dog wearing sunglasses, because he feels like the dog is judging him behind the tinted lenses.
In "Pranks for Nothing" Julian is clearly unamused with Bash's pranks and is pleased to help/watch Randy get back at Bash by humiliating him in front of the whole cafeteria. He's also calmer than usual in this episode, only seeming irritated by Bash and impressed and thankful towards Randy.
In "Julian's Birthday Surprise" Julian has his birthday party at a magic castle-type amusement center owned by his idol and magician inspiration Sinjin Nightfire. He's interested in the bag Randy has brought, which contains a chaos pearl Randy was only bringing to protect, thinking it's a present for him. When Randy changes the subject he mentions his interest in magic and calls himself an "amatuer illusionist" and tries to do a card trick, which Randy shoots down when he points out he never even picked a card. Julian is discouraged and Howard insults him, which causes Julian to get upset and run away, screaming that his birthday's ruined. Randy goes after him to comfort him, hearing him crying in a bathroom stall and deciding to talk him through it. He declines, but immediately after begins talking about how he'd been interested in magic since he was very young, so Randy decides to shloomp into the Ninjanomicon so he doesn't actually have to listen. Julian steals the bag with the chaos pearl inside while Randy's out and hides in the lost and found, sitting and holding the orb to his chest. Randy takes it back and asks if Julian feels "evil" which Julian replied to with no, but his eyes glow green when Randy walks away. While Sinjin Nightfire sets up for his performance, Julian is acting strangely and requests a special magic trick. Sinjin calls on Randy, who refuses to go up and doesn't want to leave the pearl to Howard, but eventually brings the bag up with him and climbs inside a box. Sinjin does the magic trick and Randy comes out without his bag, and realizes Julian has it. Julian refuses to give it back, having become possessed by the power of the chaos pearl. He insists he's the most powerful sorceror in the world, fighting Randy for the pearl and attacking and destroying the stage. He opens a portal to the Land of Shadows and unleases a beast with mouthed tentacles. Howard gets ahold of the pearl and grabs it with the bag, and Julian demands it back while Randy is in trouble. Howard tosses the bag and it falls towards the portal, and Julian jumps in after it. Randy grabs Julian's legs and pulls him back, but Julian's possessed and power hungry side separates from him, causing an alternate Julian to fall into the Land of Shadows with the bag and the real Julian to be pulled back to safety before the portal collapses. Sinjin Nightfire yells at Julian for destroying the place. At the end of the episode it's revealed that the alternate "Evil Julian" actually was tricked and Howard had put a broken gargoyle head in the bag instead of the chaos pearl.
