Heatmor is a bipedal, anteater-like Pokémon. It has a beige face while the rest of its fur is red with yellow stripes sharing the appearance of molten lava. On its lower abdomen, back, and underside are raised, beige-colored bands that resemble pipes, leading to its tail. Heatmor's claws, on both its feet and hands, are a dull yellow and on its wrists are raised, dented bands; both the wrists and feet are beige-colored. Its tail is dented upward and has a hole in it, similar in appearance to a muffler. It also seems to serve the same purpose as a muffler, being able to expel gases.
Durant are the preferred prey of Heatmor. Its Pokédex entry states that it burns through Durant's steel bodies with its tongue and consumes their insides. It uses its tail to absorb the air in order to keep its fire burning. Should that hole get blocked, Heatmor will become ill as a result.
