Jeremy Birnbaum

Jeremy Birnbaum is a bratty rich spoiled kid who appears in the episode "Monster Arm". He is a karate student at Marco Diaz's dojo and regularly picks on him, despite being younger.

Jeremy comes from a rich family and uses his immense wealth to buy fancy karate equipment and private lessons. Unlike Marco, Jeremy is a Tang Soo Do black belt. He is also not above cheating to get ahead in karate, as he brought a set of golden brass knuckles to a karate tournament in order to beat Marco. Unfortunately, he was found out by the Dojo Sensei and was disqualified for cheating along with Marco.

Despite the support of his parents, Jeremy appears to harbor childish resentment toward his mother.

Outside of karate, he regularly picks on Marco in school.

Appearance
During his match with Marco, Jeremy wears a white gi with a black belt, a white headband and red sparing gloves.

Outside of karate, he wears a light blue shirt and light green pants. He also wears a sweater around his neck.
