Arnold's loyal best friend and the coolest kid at P.S. 118.

Gerald Martin Johanssen (voiced by Jamil Walker Smith throughout the original series and Hey Arnold! The Movie, Benjamin Flores Jr. in Hey Arnold! The Jungle Movie, Remond Francois in Nicktoons Nick Tunes, and Ramone Hamilton in Nickelodeon Kart Racers 3: Slime Speedway and Nickelodeon All-Star Brawl 2) is a 9-year-old boy and Arnold's best friend. He is an athletic and street-smart boy who is portrayed as loyal, though much less responsible than Arnold. Gerald is shown to have known Arnold for many years, most likely since preschool.

He gets these myths from a source he has nicknamed "Fuzzy Slippers", mentioned in many episodes as his reliable assistant.

Lore & Background

At school, Gerald is the class president and considers himself "very cool", and it is shown that his friends agree. When it was revealed that Arnold was on Rhonda's so-called "Cool List", and that Gerald was on her other list known as "The Geek List" (due to a grudge Rhonda had against him over running for class president), many classmates were surprised to find this out ("Cool Party"). His most distinct features are his tall, Kid 'n Play-style hair, and his shirt with the number 33 on it (he also wears 33 on sports uniforms). He has a crush on Phoebe, who shares the same feelings for him. At the end of Hey Arnold!: The Jungle Movie they are seen holding hands.
