Top 10 Cartoon TV Sidekicks

Behind every cartoon all-star is a scene stealing supporting player. Welcome to WatchMojo.com, and today, we’re counting down our picks for the Top 10 TV Cartoon Sidekicks.  
 
For this list, we’re looking at supporting small screen characters who prove themselves useful to a hero or main character, or are at least provide good comic relief.  We’re excluding characters that are part of a duo, like Stimpy or Ferb, as they’re not so much sidekicks as they are equal partners.
 
 


 “He-Man and the Masters of the Universe” (1983-85)
When Prince Adam turns into He-Man and wields the Sword of Power, his timid pet tiger Cringer transforms into Battle Cat, growing in size and strength. The polar opposite of Cringer, Battle Cat is a fearless beast with an intimidating roar and a thirst for combat. Equipped with a helmet and saddle, this green-furred, orange- striped feline serves as a mode of transportation for He-Man and, if necessary, is always ready to leap into action.
 
 

Unbeknownst to Inspector Gadget, his resourceful niece tags along when he goes on his investigations. With the help of her dog Brain, Penny works behind the scenes to make sure her uncle is okay and to get to the bottom of the case he’s working on. A tech whiz, she uses a sophisticated computer/book to monitor the activities of M.A.D. agents and foil Dr. Claw’s evil schemes. Despite playing such an integral role, Penny always lets her uncle Gadget think he’s done it all himself. Come to think of it, maybe Penny was the show’s true hero this entire time and Gadget was the sidekick…
 

This anthropomorphic moose starred together with his pal Rocky in a collection of serials and vignettes. Despite being the frequent target of Cold War-like spies Boris and Natasha, Bullwinkle always had a cavalier attitude and was oblivious to his predicaments. Though the show was originally called “Rocky and His Friends,” this whimsical sidekick was so popular that the series was renamed “The Bullwinkle Show” by its third season. Talk about a character that stole the show!
 

Next door neighbor and best friend to Kim Possible since childhood, Ron assists Kim when she’s out saving the world… but whether it’s his enemies or his peers, no one actually takes him seriously. Full of idiosyncrasies, Ron has a naked mole rat named Rufus and an irrational fear of monkeys. Though they start off as just friends, later in the series, Ron and Kim develop a romantic relationship that appeased shippers around the world. Who says that the sidekick can’t get the girl?  
  

A flamboyant robot with delusions of grandeur, Bender is the best friend of Philip Fry and a member of the Planet Express delivery crew. Prone to debauchery, he’s a bad influence to those around him, and he’s not above stabbing his friends in the back. Selfish and lazy, Bender tries to get by doing as little as possible, but occasionally he ends up doing the right thing. Even if he is clearly going to robot hell, we’d love to share a beer with him regardless.
 

This jumpsuit-clad reporter for Channel 6 News is one of the few humans the Turtles and Splinter can trust. Showing concern for the Turtles, she is sympathetic to their cause and helps them any way she can. Intuitive and quick on her feet, April uses her investigative skills to collect information on Shredder and Krang. She gets captured on a constant basis, but the Turtles always come to rescue her. April would notably become more independent as well as hold different jobs in later incarnations, but she still maintained everything that made her character delightful to begin with.
