This deadly Forest parasite attacks his victims from inside and kills them little by little. After his coincidental Corruption, Wormhole acquired a new ability: Now he can't just kill his victims and then move on to the next monster. If he wants, he can keep and control the bodies of his victims after he's killed them. The last monster he devoured from within had a very unique power: He could gain the appearance of any other monster, so Wormhole decided to keep his body as his most recurrent clothing. While he's in this skin, he can disguise himself and go almost everywhere. He'll fool anyone... as long as he doesn't have to speak. Language is one of the few weaknesses Wormhole has.

Wormhole is a Nature Support monster who can Disable Traits, Break Shields, and Blind enemies. He can also apply Tortures like Nanovirus, Poison, or Sunburn to them. He has an Evolving Trait: at rank 0, he's Immune to Stun, at rank 1, he gains Immunity to Freeze and, at rank 3, he applies Nanovirus to all enemies at the start of every battle.
