Main characters

 * Tobias Mordecai "Toby" Brooks / Red Ninja (voiced by Ben Schwartz)''': A Ca Frost Science Academy High School freshman and Rochelle's older twin brother who was born five minutes before Rochelle and was chosen to be the "Red Ninja Rabbit", a mystic warrior who protects the school and the city from any danger that threatens the safety of people. 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. Toby is a young student who faces monsters and freaks to keep the evil Samurai in their arrest.
 * Rochelle Elizabeth "Shelli" Brooks / Blue Ninja (voiced by Heather Arney)''': A Ca Frost Science Academy High School freshman and Toby's younger twin sister who was born five minutes after Toby and was chosen to be the "Blue Ninja Rabbit", a mystic second warrior and Red Ninja's younger twin sidekick who protects the school and the city from any danger that threatens the safety of people. She is generally wisecracking, kind-hearted, sweet, zany, and thoughtful. Like Karen, she lacks stage fright, plays video games, sings karaoke, and drinks copious amounts of hot chocolate and smoothie. Of the duo of two main characters, Rochelle absolutely far more patience, responsibility, and intelligence than Howard does. Although almost every problem caused by the duo is Howard's fault, she and Toby does cause problems at times, though they are unrelated to work. Rochelle is also a young student who faces monsters and freaks to keep the evil Samurai in their arrest. She is the lead member of the Glee club at High School, which competes as a show choir while its disparate members deal with social issues, especially regarding sexuality, race, relationships, and teamwork.
 * Howard Timothy Cunningham / Green Ninja (voiced by William Salyers): Howard is Toby's half-Chinese best friend and the only one who knows (then generally knows) their secret identity as the Ninjas. He can be best described as a "wild teenager", even though he is past his early teenage years. He becomes frustrated, frightened, confused or sad very easily, making his behavior very predictable. 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.
 * Katherine Sophie "Karen" Boonchuy-Cheng / Yellow Ninja (voiced by Kimberly Brooks)''': Karen is Rochelle's African-American best friend, Toby's love interest (later girlfriend starting from the beginning of season 3), Arturo and Sabine's daughter, 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.

Supporting characters

 * Chester (voiced by Sean Astin): Toby Brooks' pet talking | Siberian Husky dog. Although he does value Fangs as a friend, he is often exasperated with him. This is mainly because he is constantly terrified of the monsters and supernatural phenomena that happen around him and his friends. He does appear to be a good thinker in certain situations, which has been acknowledged by Harold, although Harold has also correctly pointed out that "Chester's pretty smart, but he never actually learns from his mistakes". Chester is also a fan of sudoku and jazz music.
 * Talinda (voiced by Leigh-Allyn Baker): Rochelle Brooks' pet talking | Maine Coon cat. She is very athletic, allergic to petunias, has an obsessive-compulsive addiction for organizing, and loves cats.
 * Leo (voiced by Bobby Moynihan): A talking pet | hamster and Chester's best friend. He has a crush on Bessy, the sassy and sarcastic cow best friend of Abby, but she always rejects him. Leo is not usually involved with the gang's crazy schemes as much as Crusoe, Elizabeth, Fangs, etc. are, but still, he usually comes along for the ride. Leo's human disguise makes people question him, to which another animal says 'He's the world's smallest man!'.
 * Elizabeth (voiced by Myrna Velasco): The intelligent, but smart, germophobic, and occasionally shy talking pet | canary who is best friends with Crusoe, is fond of cleaning and appears to be unaware of Crusoe's recurring urges to eat her.

 * Crusoe (voiced by Cam Clarke): Karen Boonchuy's pet and very funny, but dim-witted talking half-panda and half-ferret (although he more closely resembles a | ferret and a waddling | kangaroo) who is best friends with Elizabeth; he used to be a carnivore, but then he's become a vegetarian to assimilate to Karen's apartment.

Mark's most original appearances in the series portray him as a bully who would annoy Rochelle with embarrassing pranks.
