Pokemon's First Appearance: Pokemon Gold, Silver & Crystal

Houndoom is, in every way, Pokemon's dog from hell. From its appearance to its attacks Houndoom is deadly. Although most of Houndoom's major attacks are Dark types, it also knows Fire, Grass, Fighting and Steel attacks, and has a base stat total of 500. However, even this hell hound has its weaknesses. Houndoom is weak to Fighting, Ground, Rock and Water attacks. Just don't talk about Houndoom's weaknesses in front of it. You might regret it.
