If your opponent's Bench isn't full, look at his or her hand. If your opponent has any Baby Pokémon or Basic Pokémon there, choose 1 of them and put it on his or her Bench. Then, switch it with the Defending Pokémon.
Dark Fire じごくのほのお
30+
If there are any Energy cards attached to Dark Houndoom, discard 1 of them and this attack does 30 damage plus 20 more damage (plus 10 more damage for the Energy you discarded). If there aren't any, this attack does 30 damage.
The flame it breathes is actually a volatile poison it produces internally that ignites when exposed to air.
口から吹き出す炎は、体内のどくそを燃やしたもの。つきさすようなにおいがする。
Trivia
Along with Dark Tyranitar, Houndoom is one of the two Dark-type Pokémon released as a Dark Pokémon. This is done due to its secondary type of Fire, as no Darkness-type Pokémon were made into Dark Pokémon in Neo Destiny.
