•
Stacy Stickler: (voiced by Ashley Taylor (Tickell)) One of the main
protagonists. An 8-year-old (later 9) quiet-but-bossy girl dressed in orange who liked to imagine many things with Bradley. She often says "For your big fat information" and her catchphrase "Real mature, Bradley". She sometimes serves as the voice of reason for Bradley's silliness and carelessness. •
Bradley: (voiced by Ashley Brown) The other main protagonist is Stacy's 9-year-old (later 10) best friend. He is African-Canadian and wears thick black-framed glasses along a red backwards cap. He often imagines himself as a superhero, secret agent, robot, or a vampire, namely as "Rubber Guy", "Cap Crusader"," 00 Bradley", "Robo Bradley", or "Count Vladley". His favourite fantasy is "Aliens from Uranus" are behind whatever problem they are facing, much to Stacy's annoyance. •
Frank: Stacy's obese pet Dachshund dog who sometimes shares in their adventures and liked to eat something different. Due to his insatiable appetite, he often sees things as food. He is very lazy and does not exercise much apart from chasing Stacy on the way to school. He is named after a term of meat. •
Lester: Bradley's pet chameleon who mixes into the background and causes a lot of trouble. •
Lance: (voiced by Andrew Craig) An evil bully who loves to pick on everyone in school, especially Bradley, whom he nicknames "Scradley". •
Russell: (voiced by Amos Crawley) Lance's dimwitted best friend and sidekick (minion of Stacy and Bradley) and carries around with him a horrible odour. He always says "What?" when everyone says "Whoa Man! What's that funky smell?" and he repeats everything that Lance says. He actually says "Yeah... [either what Lance said, or a synonym/variant]". He does surprisingly well in the classroom. •
Polly: (voiced by Marianna Galati) Lance's friendly, intelligent younger half-sister who always gives words of knowledge and wisdom. She is often seen walking her lifeless pet poodle, Pepperoni, whom she refuses to believe is dead; she dislikes being called a baby, though. •
Pepperoni: Pepperoni, as mentioned above, is Polly's lifeless pet dog. Polly is normally seen dragging Pepperoni around by his leash. He is named after an Italian meat topping. •
Dill: (voiced by Daniel Goodfellow) Loudest friend of Stacy and Bradley who has an ear-splitting voice. Often, uses the words "HOLY MACKEREL!". •
Stella Stickler: (voiced by
Catherine Disher) Stacy's caring but also hot-headed mother. She loves fashion, she works hard, and dislikes being annoyed by Stacy and Bradley sometimes. She is divorced from her husband Stanley. She is very annoyed when Stanley is trying to "fix" things. •
Stanley Stickler: (voiced by Philip Williams) Stacy's ambitious father. His inventions go wrong and he is bad at cooking. A running gag is that he's always trying to fix appliances. He is divorced from his wife Stella. As mentioned in the first episode entitled "Aaand Action!", he lives in "his own place" in the same apt building (located at Latchkey Gardens). He also seems to be kind of forgetful, because in the episode "Madam Know-It-All" it's a running gag that he thinks that his family has a lawn, but it's green gravel. He still doesn't seem to get that this "lawn" is never made out of grass because in the episode "We're Doomed" from the third (and final) season, he still thinks that it is grass; and on the episode "It's My Parties" from the second season, in which he didn't realize it was Stella's turn to throw a surprise birthday party for Stacy. •
Ms. Mobley: (voiced by
Melleny Brown) Stacy and Bradley's cheerful-but-crazy teacher. She frequently says "Won't that be fun?" to one of them. •
Principal Coffin:(voiced by
Benedict Campbell) A creepy school principal who looks like a hybrid between a zombie and a vampire. He speaks in a slow, spooky accent. •
Mr. Lederhosen: (voiced by
Ron Rubin) The class' tough, European gym teacher who acts like a military sergeant major. •
Mr. Doddler: (voiced by Nicholas Rice) A senior citizen who wears a fez with a crescent moon on it. He is a farmer who often grows the ingredients to make the kids' favourite snack, Cheez Poopers, that are similar to
Wotsits. Stacy usually calls him "Mr. D". •
William: (voiced by
Daniel DeSanto) A chubby boy who liked eating. •
Melody: (voiced by
Leah Renee Cudmore) Stacy and Bradley's disabled classmate who uses a wheelchair. She occasionally teams up with Stacy against Bradley and Dill. •
Ashley: (voiced by
Lisa Yamanaka) Stacy's rival and the wealthiest girl in school. She always wears a beret and is normally seen acting as somewhat of a snob and a spoiled brat. •
Mrs. Salazar: (voiced by
Allegra Fulton) A Hispanic woman who is Stacy and Bradley's kind-hearted neighbour. •
Pickle: Dill's pet parrot. His name is a pun on a dill pickle (a food). •
Scooter: William's pet
hamster. •
Freddy: Melody's pet
maggot. ==Production and reception==
