Main Blaze Blaze (voiced by
Nolan North) is the main host of the series and central character as well as an orange-red monster truck who is good-hearted, loyal, and brave. He is based on the first generation 2010-2014 Ford F-150 SVT Raptor in the form of a trophy truck/pre-runner, judging from the coinciding orange-red color, and has a modified version of the older generation 2004-2008 F-150's grille shaping design, along with a 2007-2013 Chevrolet Silverado's horizontal bar. He is Axle City's number 1 racer, especially with help from his Blazing Speed which is initiated by saying "Let's Blaze!". At the beginning of Season 1, Blaze becomes a Monster Machine racer after winning the Monster Machine World Championships, Season 2 has him join the Axle City Fire Department, Season 3 sees him become King of Animal Island, Season 4 has him join the Axle City Police Department to help Officer Anna, and Season 7 has him join the Renewable Energy Team. In the Season 5 episode "The Blaze Family", Blaze reveals that he has a family: an unnamed mother and father, as well as a younger sister named Sparkle. Blaze and his friends also visit VelocityVille and Animal Island. As revealed in the Season 3 episode "Need for Blazing Speed", Blaze's Blazing Speed engine is not only what he uses to unleash his Blazing Speed, but it is also what allows him to drive around in general. On his tires, he has flame patterns, and on his sides, he has his signature flame decals. A standard F-150 where the SVT Raptor was introduced would be the 12th overall. Despite being supposedly based on the SVT Raptor, Blaze only has one row, when in reality the actual said vehicle always has 2. As a superhero, Blaze gets melting power, strength power, and flying power.
AJ AJ (speaking voices by Dusan Brown in "Blaze of Glory"–"Dragon Island Duel",
Caleel Harris in "Runaway Rocket"–Season 3, Ramone Hamilton in Season 4–"The Amazing Stunt Kitty", Jakari Fraser in "Sir Blaze and the Unicorn"–"Video Game Land: A Monster Machine Super Special", Ayden Elijah in "The Garbage Truck Challenge"–Season 9, singing voice by Jacquez Swanigan in "The Mystery Bandit"–"Rocket Ski Race", Reed L. Shannon in "Race to Eagle Rock"–"The Gold Medal Games", Aryton Celestine in "Sparkles Racing Badge"–"A Blazing Amazing Christmas", Judah Edwards in "Renewable Energy Racers"–"Valentine's Day Rescue", and Leo Abelo Perry in "School Bus Blaze"–Season 9) is the show's African-American main co-host and Blaze's human best friend and driver. He is a science and technology expert. Season 7 sees him join the Renewable Energy Team. AJ's racing suit technology includes his Visor View in his helmet which allows him to see things no one else can. When AJ activates his Visor View, the background usually turns orange in Season 1. From Season 2 and onwards, it doesn't do that anymore. He also has skywriting gloves which allow him to draw pictures in mid-air (which has been abandoned after the events of the Season 4 episode "Ninja Blaze") and a wrist-com video watch worn on his left arm to call others. His uniform can also undergo minor changes in appearance, such as when Blaze transforms into a race car, and when Blaze uses his speed lights. As the show progressed, AJ became the one to describe the STEM concept instead of Blaze in earlier seasons.
Crusher Crusher (voiced by
Kevin Michael Richardson) is the main antagonist of the series, though he slowly evolves into a nicer character, occasionally serving as an anti-hero. He is a deep blue tractor truck with a lighter blue lightning bolt motif who is Blaze's biggest rival, based on a large 18-wheeler cargo-truck, such as a 2005
Peterbilt 386 and/or 2012 Kenworth T680. He cheats in most episodes because he would get lampooned by Blaze in a fair race. He constructs various cheating gadgets from parts that he keeps in a bag on his chassis. In the episode "Blaze's First Race", it's revealed that Pickle seems to be the one to inspire Crusher's cheating, saying, "But Crusher, pressing the button would be CHEATING," and Crusher saying that he likes the sound of cheating. While he is known for his cheating and mischievous ways, he is not all bad and not really evil. In fact, Crusher is still good at heart at times. The episode "Catch That Cake!" reveals that he has moral limits when it comes to stealing food; he admitted that he would have respected Darington's birthday cake and not taken a piece without permission, despite his temptation. In addition, Blaze and his friends are even willing to help Crusher in some instances, such as helping him find his toy truck Little Trucky in "The Mystery Bandit", and Gasquatch saving him by sneezing away a thundercloud and bringing him down from the Mud Mountain. Crusher even tried to resist cheating in "Defeat the Cheat" when he was paired with Blaze during the second Team Truck Challenge. In the episode, Crusher (along with Blaze) finally scored his first ever win, and it's also the first time Crusher doesn't show disgust after crashing into something and getting mud or food on him, as shown when he crashes into an ice cream stand while celebrating and upon tasting, he giddily says "Tastes like winning!". Season 7 sees him join the Renewable Energy Team. On his tires, he has lightning bolt patterns.
Pickle Pickle (voiced by
Nat Faxon) is a small, and green singing hatchback monster truck based on a 1975
AMC Pacer with darker green stripes and bumps on his sides, who is Crusher's sidekick despite Crusher's indifference towards him, although the two are known to be close friends most of the time. In the episode "The Pickle Family Campout", it's revealed that he has a family: 3 cousins, 5 sisters, and a Grandpa. He tends to look on the brighter side of things, is quite goofy, and has an extremely high pitch voice. Although he is by Crusher's side, Pickle is actually quite friendly towards Blaze and his friends. He took Bump Bumperman's place in "Defeat the Cheat", "Power Tires", and "The Great Pizza Race" when Bump Bumperman was busy with other stuff. Season 7 sees him join the Renewable Energy Team. In the episode "Blaze's First Race", it's revealed that Pickle met Crusher during his first ever race, and he seems to be the one to inspire Crusher's cheating, saying, "But Crusher, pressing the button would be CHEATING", and Crusher saying that he likes the sound of cheating. On his tires, he has wavy line patterns.
Gabby Gabby (voiced by Angelina Walher in Season 1–"Tow Truck Tough", Molly Jackson in "Need for Blazing Speed"–Season 5, Luna Bella Zamora in Season 6, Kensington Tallman in "Paramedic Power"–"Valentine's Day Rescue", and Micaiah Chen in "The Ice Treasure"–Season 9) is a human mechanic with light skin, blue eyes and purple hair in a ponytail held by a blue
hair tie. She wears a white shirt with blue overalls, though she switches to a white-and-blue racing suit and helmet with goggles when either driving her ATV, riding with Blaze (with three exceptions being "Epic Sail" where she only wore her helmet when she, Blaze, AJ, and Stripes went off to get the sail but later took off her helmet offscreen, "Axle City Grand Prix" when she wore her overalls when Blaze left the garage but later switched to her blue racing suit for the rest of the episode, and "Robots to the Rescue" when she was wearing her magenta racing suit in Blaze's passenger seat when Robot Blaze welcomed his friends to Robot Headquarters), or other unknown reasons. She fixes up the trucks when they are damaged and sometimes rides with AJ and Blaze to take part in some of their adventures and races, with her always doing this in the Special Missions miniseries. Season 7 sees her join the Renewable Energy Team. Gabby's outfit undergoes changes like AJ's uniform and helmet, but it only happens twice. Gabby also drives a purple ATV, but she no longer drives it anymore after "Light Riders", because starting with "Fast Friends", she is now a Monster Machine driver for Watts, but continues to work in the garage. This makes her the second character to become one and to be partnered with a Monster Machine, the first being AJ who partners with Blaze. When Gabby drives Watts, she almost always wears a white and magenta version of her racing suit, and her hair also undergoes some slight changes, such as having her ponytail being held by a magenta hair tie. She also often resembles a pickup truck intended to be a Mercedes X 360.
Stripes Stripes (voiced by Sunil Malhotra) is an orange bengal tiger truck with violet stripes and highlights on him, and the design based on multiple generations of a Jeep Wrangler. He has the abilities of a Bengal tiger, such as a high sense of smell and retractable spike-claws in his tires. He is good at jumping and climbing. In Season 3's "Wild Wheels" episodes, when Blaze transforms into a Lion Monster Machine, he shares his engineering powers to transform Stripes into a bengal tiger named Super Bengal Tiger Stripes. In "Babysitting Heroes," it reveals that Stripes can babysit baby animals. His home is a treehouse in a jungle outside Axle City. On his tires, he has stripe patterns. In "The Monster Machine Christmas Extravaganza", he is an Axle City Caroler. As a superhero, Stripes has the power of any animal.
Starla Starla (voiced by
Kate Higgins) is a purple Southern-accented pickup truck based on a lot generic, and more stubbier version of the then-new 4th-generation 2014 GMC Sierra (K2XX), with the same generation
Chevrolet Silverado wheel wells, and a silver cowgirl hat. She is a roping expert. She runs a farm outside Axle City. She's the only female Monster Machine to be a main cast member until "Watts" in Season 3. Season 7 sees her join the Renewable Energy Team. On her tires, she has horseshoe patterns. In "The Monster Machine Christmas Extravaganza", she is an Axle City Caroler. As a superhero, Starla can make any star she wants, like glowing stars, floating stars, and firework stars.
Darington Darington (voiced by
Alexander Polinsky) is a clumsy yet starry white and blue pickup truck with a gold star motif not based on any known real truck model. He also has a helmet and cape-like spoiler. He loves stunts. His catchphrase is "Darington!" In "The Chicken Circus", it is revealed that Darington can speak chicken. In "The Amazing Stunt Kitty", it is also revealed that Darington has a kitty cat named Stunt Kitty as his pet and sidekick. On his tires, he has star patterns. In "The Monster Machine Christmas Extravaganza", he is an Axle City Caroler. As a superhero, Darington can grow and shrink in size.
Zeg Zeg (voiced by
James Patrick Stuart) is a lime green dinosaur truck with ocean blue highlights and brute tendencies based on a Terradyne Gurkha/Armet Gurkha F5. He has a short vocabulary and tends to refer to himself in third person. Like most Ceratopsian dinosaurs, Zeg loves to smash. In "Race to the Top of the World," Zeg reveals that he can't swim (even though he did show to do such thing later on in Five Alarm Blaze). He has a low,
Hulk-like voice. His home is a prehistoric cave outside. In "Dino Smash!", it's revealed that Zeg has three sisters named Meg, Peg, and Egg. On his tires, he has rock patterns. In "The Monster Machine Christmas Extravaganza", he's an Axle City Caroler. His main catchphrase in multiple episodes is his name itself, "Zeg!". He's the only friend of Blaze to not have a superhero form.
Watts Watts (voiced by Melanie Minichino) is a magenta South American-accented monster truck powered by electricity. She is the latest of Blaze's friends based on a 2016 Lamborghini Huracán LP610-4 Spyder with a truck grille and bumper but actually resembles a Jaguar XJ220. She is also the second female Monster Machine to both be part of the main cast and be part of Blaze's Monster Machine friends, with the first one being Starla. Watts' features include her electric engine and her special yellow electric tires, both allowing her to drive faster, and her Electric Charge which allows her to give anything electricity so it can work. When Watts met Blaze, AJ and Gabby for the first time, she happily asks Gabby to be her driver, saying that she never had anyone driving her before. Gabby happily accepts Watts' offer, saying that she has never been a Monster Machine's driver before. Since then, Gabby is now a Monster Machine driver for Watts and the two are now very close friends. This makes Watts the second Monster Machine to be driven by a human and to be partnered with a Monster Machine driver, with the first being Blaze who partners with AJ. Despite this, however, Watts has spent a few episodes without Gabby and also completed in one race without her, unlike Blaze who always appears with AJ. On her tires, she has lightning bolt patterns just like Crusher, though hers have a different design. In "The Monster Machine Christmas Extravaganza", she is an Axle City Caroler. She is also the only main character with colored tires. As a superhero, Watts can make and ride on lightning bolts.
Sparkle Sparkle (voiced by Julieta Cortez) is Blaze's younger sister. She originally debuted as a guest character in the fifth and sixth seasons, but made periodic appearances in the next few seasons. She is based on the same type of
Ford Raptor just like him. She has hot pink hair that has pigtails with yellow stars holding them in every place. Her eyes have glittery pink eyeliner and eyelashes. She has a finish of sparkles on her tires, which has the same print as her brother. Sparkle's sides bear a smaller version of Blaze's flame symbol. Sparkle is very playful and enjoys her brother's company greatly. She also prefers fair play over cheating, putting her at odds over Crusher. Just like Blaze, Sparkle has the ability to transform into other vehicles to perform different tasks. When transforming, Sparkle retains her hair and the flame symbol, but sometimes the flame symbol takes on other guises. Like Blaze too, Sparkle has a Blazing Speed engine as well. But Sparkle's have a pink and yellow contrail similar to Blaze's. In the episode "Super Wheels vs. The Bubblemaker", Sparkle reveals that she has a dinosaur. As said above, her appearances and interaction with the viewer is one of the few aspects in hinting that Sparkle may be a second introduction of a new main character in the series after Watts. This was especially evident in "Sparkle's Big Rescue", where she took both her brother and AJ's places as the main protagonist of the episode after Crusher sent them away with the Bye-Bye Copter. As a superhero, Sparkle can make anything made of glitter.
