Having the same coloration as its pre-evolved form, Houndour, Houndoom has a taller build with a longer snout. There are two white bands at each of Houndoom's ankles instead of just one, as well as three bands on its back instead of two. Houndoom has a long, skinny tail that ends in an arrowhead and visible claws on its feet. It appears to have a collar with a small skull pendant and a pair of curled horns, but no discernible ears.
Gender differences
Female Houndoom have smaller horns.
Special abilities
Houndoom's abilities are the same as Houndour's, only stronger. As a matter of fact, legends claim that anyone that gets burned by Houndoom's Fire attacks will never be healed and that Houndoom's howling was once claimed to be the call of the Grim Reaper. Its fire comes from toxins burning in its gut, this also gives its fire a foul odor.
Behavior
Houndoom are generally very protective, alert, headstrong, intelligent, and very focused. They can be overly aggressive, but only to protect themselves, their young, their territory, or their owner. However, when properly trained, they can be extremely loyal, loving, and caring Pokémon, as well as very good pets. In a Houndoom pack, the Houndoom with its horns raked sharply towards the back serves a leadership role. Houndoom choose their leader by fighting amongst themselves.
A group of Houndoom first appeared in Volume 13, used by Carl to prevent Gold and Crystal from attacking with their Roar attack.
Maxie is revealed to have five Houndoom in his arsenal, one of which he used to kill Norman to prevent him from using Rayquaza to interrupt Kyogre and Groudon's fight again.
