Benjamin Kirby "Ben" Tennyson was a normal ten-year-old kid until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten different aliens. Though initially immature and clumsy, Ben grew to be a true hero. By the time he was sixteen, he had become famous in not only his hometown of Bellwood, but on Earth and beyond. Ben has also been deputized by the Plumbers and gained more aliens as time progressed.

Heatblast

Main article: Heatblast

Heatblast is a magma-based alien whose body is composed of a bright yellow inner magma body covered by a dark red or brown rocks. As a fire-based entity, his body radiates high amounts of heat. His feet have a slight oval-like design with only two toes and one back toe. Heatblast's tongue is made of fire.[1]

4 year old Heatblast looked the same as 10 year old Heatblast in the original series, but with a much thinner body, oversized head and much higher-pitched voice.

In Ultimate Alien, Heatblast closely resembled Alan, only taller and not as skinny and slightly altered and his face shape was more similar to the Original Series. His eyes were no longer connected to the fire on his head. The rocks over his body were darker, and their pattern was different, with fewer rocks covering his inner lava body. His voice sounded like Jetray's, except deeper.

In Heroes United, Heatblast looked the exact same as he did in the original series, only his jaw was a lot lower than it was before.

In The Forge of Creation, 10 year old Heatblast is a mix between the Ultimate Alien design and the original series' body colour and his Omnitrix symbol was green.

In Omniverse, 16 year old Heatblast looks the same as in Ultimate Alien, only his eyes are once again connected to the fire on his head, like in the original series. He is taller and more muscular, his face's design is different and his shoulder plates are slightly tilted up.

11 year old Ben's Heatblast in Omniverse looks exactly the same as the 16 year old Heatblast, except for the fact that he is shorter and much less muscular then his sixteen year old self.

Heatblast wears the Omnitrix/Ultimatrix symbol on his chest

In the original series, Diamondhead wore a uniform which was black on the right half and white on the left with a black patch on the left shoulder where the Omnitrix symbol was.

In Alien Force and Ultimate Alien, Diamondhead's lower body, torso, and the top of his head were similar to Chromastone's, consisting of indigo crystal which has black lines and dots over it. There were six crystal shards on his back instead of four, and he also sported two more on the front of his chest. His eyes were green, and he wore the Omnitrix/Ultimatrix symbol on his chest.

In Heroes United, Diamondhead's appearance consisted of real-world crystal due to being drawn in Generator Rex's art style. He also had blades on his forearms.

In Omniverse, Diamondhead has clothing almost similar to the first series, except that now instead of half black and half white, it is all black with one large green stripe down the middle up to his belt, and wears black pants. He has a green belt with white stripes on which he wears the Omnitrix symbol. Diamondhead no longer bears the crystals on his chest. The crystals on his back have also grown in length. His jaw is also larger. He also wears black shoes with green on the bottom. There are now only two crystal shards on his back.

11-year old Ben's Diamondhead looks almost identical to the original, but the left side of his suit is missing the black patch around the Omnitrix symbol and the crystals on his back are bigger. His jaw is also larger too. His eyes are green and the Omnitrix is recolored.
