Jaren is a young boy with short blonde hair that he stylizes with hair gel. He wears a blue A-shirt with a red arrow pointing upwards over a regular orange shirt, a pair of khaki pants and blue shoes. He is seen once in his underwear, which are neon green with purple polka dots, he also wears knee length socks with two orange stripes at the end of them. His upper body may have a bit of a muscular build, as seen when he was half-naked.
PersonalityIn his very short appearance more than halfway through the "Shapeshifter", Jaren appears to be quite an egoistical young man. He turns into a wreck after he realizes that his pants and hair gel were stolen from him and cries out in agony while exhibiting himself half-naked in the streets. Because of this dilemma, it is mentioned that he may not be able to summon enough courage to take the stage as scheduled.
Jaren is a teen pop star that many teenage girls obsess over, including Rose and her friend Courtney. One of his biggest hit singles is called Girls, Don't Be Trippin'. He planned to have a concert at the Radio City Music Hall in New York City in "Shapeshifter", although it is unknown if he actually did his how after his pants and hair gel were stolen.
Jaren also participated in the 3rd Annual Hip-Hop Video Awards in "The Legend of Dragon Tooth" with his hit single Baby, Baby, Baby, Baby, Baby, Baby (although this is only mentioned and never actually seen);
