Braxien is a bipedal fox-like Pokémon; unlike its pre-evolution Fennekin, it now stands upright on two legs. Braxien is covered mainly in bright yellow fur (with a black underside) that resembles a skirt; it has a collar of fluffy white fur below its thin neck and covering on its chest. It has a long pointed snout with a round orange nose, and bright orange eyes. Braxien has tufts of bright orange fur sprouting from its ears. It has a branch embedded in its bushy yellow orange-tipped tail, which it uses as a wand to emit blasts of flame. When pulling its branch from its tail the friction causes the tip of the branch to catch fire.
Once Fennekin evolves into Braixen, it no longer eats branches for snacks, but will still keep a tree branch in its tail in order to fight with. Braixen will occasionally wield the branch in battle and use friction to light it on fire, as if it is a wand.
Braxien evolves from Fennekin at level 16. It evolves into Delphox at level 36.
