Charmander is an orange, bipedal, reptilian creature. Charmander has two small fangs visible on its upper and lower jaws and blue eyes. It has a cream-colored underside and an expansive cream marking on the soles of its feet. Its arms and legs are short, and it has four fingers and three clawed toes. A flame burns on the tip of its tail, which is there even at birth. This flame can be used as an indication of Charmander's health and mood. The flame burns brightly when it is strong and weakly when it is weak. When Charmander is happy, the flame will waver; it will blaze if Charmander is enraged.
This Charmander is extremely energetic, always exhibiting a dance when it comes out of its Pokéball. As Silus was the one of the first humans it saw (Clair claims it had never seen her), it immediately became attached to him, affectionately hugging him whenever it gets done with its little dance, or whenever it greets him. Additionally, it seems to have become instantly protective of its trainer.
Charmander possess the Ability Blaze, which tremendously increases its power if it comes close to fainting. As the offspring of two Charizard, one of which was Clair's, it inherited the ability to use Flare Blitz.
