Meet the Cast of Hey Arnold! - Full List of Characters

"Hey Arnold!" is a beloved animated television series that has captured the hearts of many viewers. The show follows the daily life of Arnold, a fourth-grader with a unique blend of imagination, street smarts, and a distinctive football-shaped head. Voiced by the talented Francesca Marie Smith, Arnold's character is brought to life with a charm that resonates with audiences of all ages.

The show is further enriched by a diverse cast of characters, each with their own unique personalities and backgrounds. Among them is Helga Pataki, Arnold's classmate and secret admirer, voiced by Francesca Marie Smith. Helga's character is a complex one, often portrayed as a bully but with a softer, more vulnerable side that she keeps hidden. Her unrequited love for Arnold adds a layer of depth to the show, making it more than just a simple children's cartoon.

Another significant character is Gerald Johanssen, Arnold's best friend and confidant. Gerald, voiced by Jamil Walker Smith, is a reliable and loyal friend who often serves as Arnold's voice of reason. His character adds a sense of stability and camaraderie to the show, balancing out the more eccentric personalities of the other characters. The dynamic between Arnold, Helga, and Gerald, along with the rest of the cast, makes "Hey Arnold!" a must-watch for anyone looking for a heartwarming and entertaining show.
