Blaze's horn sound is the most unique as it plays a seven-note melody (D-D-G-G-B-B-A). Those who have seen the show multiple times will know it plays a variation of the chorus melody for the Blaze and the Monster Machines Theme.
In The Driving Force, his horn was low-pitched twice, once when leaving the canyon and again when he returns to the Monster Dome. His horn also produces a generic one-note sound just after the STEM song before Gabby calls him.
The low-pitched version of his horn is used for the Super Stunts Blaze toy.
In Season 1, Blaze's voice was slightly low-pitched, and had a little bit of scratch in it. By the time Season 2 began, his voice became higher-pitched and lost the scratch, sounding more youthful and eccentric.
Blaze has only gotten dizzy four times so far; for a brief moment in Blaze of Glory when he crashes into Axle City, in Stuntmania! when he gets bumped by the first bighorn while going up the hill, in Sneezing Cold when he repeatedly sneezes and reverses into a tree, and in Robot Power when he gets blasted into a pile of tires by the blasting robot.
Dragon Island Duel is the only episode to date where Blaze has a supporting role, since AJ has more screentime and interaction with the viewer throughout said episode.
Blaze rarely gets angry or sad throughout the series. The first time he showed actual anger was in Stuntmania! when he scolds Crusher for kicking Darington out of Stuntmania. He was also actually sad for the first time in Truckball Team-Up when he returns to AJ and Gabby after learning he cannot participate in the Truckball tournament without a team. He became sad again in Race Car Superstar when Speedrick got away the first time.
The Mystery Bandit is the first episode where Blaze shows a hint of impatience, as when he goes into position to take a picture with Ferris and he doesn't do anything before realizing he forgot his camera, he shifts his eyes back and forth while still holding his smile.
Blaze has a special leitmotif that plays usually whenever his Blazing Speed is in use, consisting of lively rock music played in the key of A major.
Every time Blaze is shown looking forward, his eyes appear to cross slightly inward in the center. This might indicate he has a lazy eye, though this could be intentional.
Almost every time Blaze smiles, he has his teeth showing.
In addition, during Season 1, sometimes Blaze would cock either lower edge of his mouth to the side when smiling. This has been abandoned by the start of Season 2.
In a few episodes of Season 1, when Blaze responded to a "yes/no" question he asks the viewer, he uses physical body talk when he speaks. For a "yes" answer, he smiles and/or nods; for a "no" answer, he frowns and/or shakes his head. This has rarely been used since Season 2 and onward.
In The Polar Derby, he and his friends almost got squished by the various balls launched from Crusher’s abominable blaster.
In early stages of production, Blaze’s fog lights were blue, his top area had a more angular look, and already had taillights on his bumper. He also had silver rims that were only red were the metal makes contact with the rubber. Blaze's early artwork also has his front fading from orange and a different flame pattern. Unlike the final design, Blaze's prototype had a protruding bullbar sticking out from under his bumper.
For the first three seasons, Blaze's bumper didn't have taillights unlike the others. Since the animation was updated midway through Season 3, he had taillights added.
In said updated animation, the yellow lining on his spoiler was removed for unknown reasons.
Blaze is the only vehicle on the show with an eye color visible, in this case, he has dark blue eyes. All the other vehicles use the standard black eyes.
Blaze is also the only Monster Machine who went through three different facemolds, as his face seemed slightly different in Seasons 2-3 than it did in Season 1, appearing more realistic-looking and less exaggerated. The rest of the Monster Machines kept their own facemolds intact.
Whenever Blaze is driving, the spinning animations on his tires are out of alignment with each other, as the right movements are slightly lower than the ones on the left. He's the only truck that has this; all the others have their tire driving animations completely aligned.
However, when Blaze turns into a race car for the Race Car Adventures episodes and drives, his tires are in perfect alignment.
