He is mild-mannered, laid-back, quick-witted, and intelligent. Like Howard, he lacks Spanish, plays video games, sings karaoke, and drinks copious amounts of coffee and soda. Of the duo of two main characters, Toby displays far more patience, responsibility, and intelligence than Howard does. Although almost every problem caused by the duo is Howard's fault, he and Rochelle does cause problems at times, though they are unrelated to work.

Howard is also very arrogant, impulsive, impatient and immature at times, giving him the personality of a child. Thus, he can be considered the opposite of Toby, who demonstrates far more responsibility and maturity than him (in most conditions). He was chosen to be the "Green Ninja Raccoon", a mystic third warrior and Red Ninja's second sidekick who protects the school and the city from any danger that threatens the safety of people.
 * Karen Sophie Boonchuy / Yellow Ninja (voiced by Kimberly Brooks)''': Karen is Rochelle's African-American best friend, Toby's love interest (later girlfriend starting from the end of season 2), and the only one who keeps their secret identity as the Ninjas. She can be very shy and nervous. When she has to she is brave, heroic, and will never try, but do to save the day. Even though she is shy, that doesn't mean she doesn't know how to put bad guys in their place. She is also the member of the Glee club at High School and a fan of the ninja which was chosen to be the "Yellow Ninja Canary", a mystic fourth warrior and Red Ninja's third sidekick who protects the school and the city from any danger that threatens the safety of people.
