Curse and Abilities
Poison Curse (毒の呪い Doku no Noroi): This is a curse which allows Hazard to create and manipulate toxic poison in any manner that he wants. He can also use this curse to strengthen the effectiveness of the poison he use to attack but not when he defends.
 * Immunity to Poison and Toxins: Thanks to his curse, Hazard is now immune to all toxins and poison because it strengthens him and also, thanks to this, his is vulnerable to all kinds of healing.
 * Poison Typhoon (毒台風 Doku Taifū): This move allows Hazard to create a large typhoon of poison and use it to attack his opponent or to counter his opponents attack. This spell is at its peak when he is surrounded by poison.
 * Poison Shredder (毒シュレッダー Doku Shureddā): This spell allows Hazard to release shards of poison from the poison he creates. This is a powerful spell because if a shard should pierce the skin, it could damage the opponents immune system and have a later effect of toxic death. The spell wears off if Hazard is defeated by his opponent.
 * Niagara Falls (ナイアガラの滝 Naiagara Notaki): This is his most powerful spell because this allows Hazard to create a large ocean of poisoned water which rains from the sky. He can use this as a battlefield in which his body heals from every damage inflicted on him. If he is defeated, the poisoned water will return back to the sky.
