After that, when Masashi's Deck was destroyed by Ren in the Mirror World during a battle. Volcancer attacked, crushed and ate Masashi as the destruction of his deck and cards had also resulted in a breach of his contract with the monster.

Volcancer was eventually destroyed by Ryuki's Dragon Rider Kick and its essence absorbed by Darkwing when Ryuki told Dragredder not to absorb it.
