Ultimate Heatblast has a body that is much more larger and bulky than his default form, with molten rock spikes that are sticking from his chest over his shoulders. His head no longer is engulfed in flames, instead being totally encased in hot plasma. He losses his uniform, and his legs turned to melting plasma. His face has changed in structure and gained two horns.
The Ultimatrix symbol is located on his chest.
- Enhanced Biology- Ultimate Heatblast possesses enhanced physical characteristics, such as increased strength, durability, stamina, agility, dexterity and endurance, his innate abilities, etc. They far outperform their original counterpart.
- Fire Manipulation- Similar to his default form, Ultimate Heatblast can produce and manipulate intense heat from his body. From a ball of fire, a flamethrower, to a tornado of flame.
- Plasma Merger- Ultimate Heatblast can increase the mass of his plasma and combine it with the environment around him. He can then control these large extensions of his own body, mostly in the form of large arms, for many purposes.
- Flight- Ultimate Heatblast is now capable of morphing the plasma and stone on his back to form wings, allowing him a more stable form of flight.
- Weapon Generation- Ultimate Heatblast is able to generate and shape his plasma into weapons, allowing him to use for combat.
- Armor Generation- He can generate extra stone platting around his body for protection.
- Fire Immunity- Ultimate Heatblast is immune to all forms of heat, as he is completely composed of highly intense plasma and stone.
- Water/Ice Immunity- Because of his very high temperature, he is immune to cold environments, and can no longer be put out by water.
- Heat Absorption- Ultimate Heatblast is able to absorb flames and other forms of heat around him and into his body.
- Pyrokinetic Flight- Ultimate Heatblast can release fire through his hands and feet to propel himself off the ground, like a jetpack. Although because of his new ability to generate wings, it's unlikely he relies on this too much.
- Supernova Creation- When angered, Ultimate Heatblast is able to reach supernova level temperatures that could in theory melt entire cities.
- Terrakinesis- Ultimate Heatblast is capable of a much larger level terrakinesis then his default form, by channeling plasma through the ground.
- Hazardous Body- Despite his powerful nature, his entire body is a hazard to most environments not normally equipped to handle his heat. His presence alone can cause the floor and objects around him to melt, and most other species cannot get too close to him.
