Delphox is a relatively tall bipedal Pokémon resembling a fox. It is covered in a coat of fur that resembles a robe; this "robe" is primarily dark red, with red-orange, flame-like markings near its knees, as well as a thin tuft of white fur on its torso, flanked by yellow fur draping down from its shoulders. It has three tufts of red-orange fur protruding out of each ear. Its forearms feature long red fur resembling sleeves, and its hands and feet are dark gray with three clawed fingers and toes, respectively. A tail covered in yellow fur protrudes from its "robe". When its mouth is open, two pointed teeth can be seen on its upper jaw.
Delphox carries a stick that it uses like a magic wand; when in use, the tip is set alight, and when not in use, the stick is hidden away in its sleeve-like fur. Delphox gazes into the flame at the tip of its "wand" to achieve a focused state of mind that allows it to see into the future. It can use its psychic power to ensnare its enemies in a fiery vortex capable of reaching 5,400 degrees Fahrenheit. Prior to Omega Ruby and Alpha Sapphire, Delphox was the only known Pokémon capable of learning Mystical Fire.
Delphox, the Fox Pokémon, and the final evolved form of Fennekin. When Delphox stares into the flame on the tip of its branch to achieve a focus state, it creates a bright hot spiral of fire with its psychic power.
Delphox's evolutionary family is based on a fox, specifically resembling the fennec fox. It also shares characteristics with kitsune and kitsune-mochi, witches in Japanese folklore that inherit their powers from foxes. Delphox's robe-like fur and use of a wand-like branch are likely derived from mages, while its prophetic abilities may be derived from oracles. The sleeve-like fur on Delphox's forearms are similar to the furi of a kimono.
