Cinderace is a bipedal, rabbit-like Pokémon. Most of its torso and head, as well as its arms and tail, are white. Cinderace has long white ears, the insides of which are yellow. Its white eyes, which have red-orange irises, have a deep navy pattern below them and yellow eyebrows above them. These eyebrows connect at the nose, which is red-orange, and form a "crown", which connects to the red-orange tuft of hair sticking out from its forehead, similar to a flame. It has two whisker-like tufts of white fur on each side of its face. Over each shoulder is a navy patch of fur, resembling a shoulder brace, which continues down the torso and connect at middle of the chest, creating what resembles a sports tank top. This navy-colored fur is also seen on its lower torso, creating what resembles a belt. The fur on its lower body is colored red-orange and resembles a pair of pants, with yellow pockets and ending in yellow tufts at the knees, with little tufts of fur on the backside of its thighs. Its ankles and feet are colored navy-blue and tipped red-orange at the toes. On the underside of each foot, there are three yellow dots of fur, from which it fires flames when attacking opponents.
By juggling a pebble with its feet, Cinderace can transform it into a burning soccer ball. By putting a spin on the ball, it can launch attacks that its opponents struggle to evade. The shots it fires can leave an opponent scorched. Cinderace has great offensive and defensive capabilities, being one of the best at explosive force, jumping ability, and kicking power. Due to its strong core and great balance, Cinderace can unleash powerful kicks from any position. In battle, it uses artful footwork to feint and throw its opponents off. Cinderace can get pumped up with excitement should it get cheered on. However, it may get itself in trouble if it starts showboating.
As Gigantamax Cinderace, its body is generally larger with very few alterations, save for its ears which have become longer. It rides on a Pyro Ball that has enlarged into a giant orange fireball due to Gigantamax energy, sometimes exceeding 300 feet (90 meters) in size. The fireball has a white nose and eyes, as well as several wisps of fire resembling Cinderace's ears and crown-like eyebrows. Three red clouds float above Gigantamax Cinderace.
Using its well-honed techniques and fighting spirit, Gigantamax Cinderace can make its fireball chase after opponents almost like it had a mind of its own; this attack will thus never miss. Gigantamax Cinderace is said to have the strongest leg strength of any Pokémon. Without its giant Pyro Ball, it can still overwhelm even a Dynamax Pokémon by delivering powerful kicking moves.
