<Ul> <Li> Blaze (voiced by Nolan North) is an orange - red monster truck who is good hearted, loyal and brave . As one of the main protagonists, he is Axle City's number one racer, especially with help from his Blazing Speed . At the start of Season 2, Blaze becomes the newest member of the Axle City Fire Department . He & his friends would also visit VelocityVille (where they turn into Race Cars to take part in adventures & Race Car Events), & Animal Island (to visit their animal friends & transform into animals for competitions or to take care of problems and / or obstacles). As revealed in Season 3, 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 . As of Season 3, starting with the "Wild Wheels" episodes, Blaze's design has been slightly upgraded to have the addition of tail lights, coinciding with the series' upgraded animation . Blaze, along with his Monster Machine friends & Gabby's ATV, also have additional features as well, such as grappling lines to tow fellow Monster Machines out of trouble & Speed Lights to illuminate themselves in the dark & race in the dark in one of Axle City's outdoor race tracks . </Li> <Li> AJ (voiced by Dusan Brown (season 1--early season 2) and later by Caleel Harris) is Blaze's best friend and driver, an eight - year - old science and technology expert . AJ's racing suit technology includes his Visor View & a wrist - com video watch worn on his left arm . His uniform can also undergo minor changes in appearance, such as when Blaze transforms into a Race Car, & Blaze using his Speed Lights . </Li> <Li> Gabby (voiced by Angelina Wahler in 2014 through 2017, and later by Molly Jackson in 2018 - Present) is a knowledgeable 9 - year old mechanic who fixes up the trucks when they are damaged, and sometimes rides with AJ & Blaze to take part in some of their adventures . Gabby's uniform & helmet undergoes changes like AJ's, but so far, it has only happened once (when Gabby's ATV uses Speed Lights). Gabby usually drives a purple ATV, but as of Season 3, Gabby, like AJ, is now a Monster Machine driver, driving with her new close friend, Watts . This makes Gabby the first female Monster Machine driver, the second Monster Machine driver in general (with the first being AJ), and both the first female Monster Machine driver AND first Monster Machine driver in general to be partnered with a female Monster Machine (in this case: Watts). </Li> <Li> Stripes (voiced by Sunil Malhotra) is a striped truck with the abilities of a tiger such as a high sense of smell and retractable claws in his tires . In Season 3's "Wild Wheels" episodes, when Blaze transforms into a Lion Monster Machine, he shares his engineering powers to transform Stripes into Super Tiger Stripes . </Li> <Li> Starla (voiced by Kate Higgins) is a purple pickup truck, a roping expert and speaks with a thick southern accent . She runs a farm outside the city . </Li> <Li> Darington (voiced by Alexander Polinsky) is a clumsy yet fearless blue monster truck who loves stunts . </Li> <Li> Zeg (voiced by James Patrick Stuart) is a half - triceratops, half - monster truck with brute tendencies . He has a short vocabulary and tends to refer to himself in third person . </Li> <Li> Watts (voiced by Melanie Minichino) is a magenta Monster Machine powered by electricity & the latest of Blaze's Monster Machine friends as of Season 3 (as shown from the updated standard Opening Sequence with the upgraded animation as of "Animal Island"). Watts is also the second female Monster Machine to both be part of the Main Cast & be part of Blaze's Machine friends, with the first female Monster Machine to do so being Starla . Watts' features include her electric engine & her electric tires, both allowing her to drive fast with her Electric Charge . When Watts met Blaze, AJ, & Gabby for the first time, Watts 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 (just like AJ is Blaze's Monster Machine driver), & the 2 are now very close friends (just like Blaze & AJ are close friends). This makes Watts the first female Monster Machine capable of being driven by a human, the second Monster Machine in general to do so (with the first being Blaze), and both the first female Monster Machine AND first Monster Machine in general to be partnered with a female Monster Machine driver (in this case: Gabby). </Li> <Li> Crusher (voiced by Kevin Michael Richardson) is Blaze and AJ's rival and the main antagonist of the series . He is childish, whiny, egotistical, and he cheats in most episodes just to get his way . While he is known for his cheating & mischievious ways, he is not all bad & not really evil . Examples of are shown when Crusher is willing to help Blaze save the Christmas Presents, and when he admits that he'd never steal anyone else's birthday cake when he realizes that it was Darrington's birthday cake that he was trying to take . 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", Gasqautch saving him by sneezing away a thundercloud & then bringing him down from Mud Mountain, & Gabby fixing his muffler / exhaust pipe when it got broken . </Li> <Li> Pickle (voiced by Nat Faxon) is a green monster truck who is Crusher's sidekick despite Crusher's indifference towards him, although the 2 are known to be close friends most of the time . He tends to look on the brighter side of things and is quite goofy and has an extremely high pitch voice . Although he is by Crusher's side, Pickle has is actually quite friendly towards Blaze and his friends . </Li> </Ul> <Li> Blaze (voiced by Nolan North) is an orange - red monster truck who is good hearted, loyal and brave .
