An Awful Virus is a very rare entity appearing exclusively in WarioWare: Touched!, along with the Wario Virus. Like the Wario Virus, only three appear in the game, and very briefly. Unlike the other virus variety, Awful Viruses, as their name would suggest, are harmful rather than beneficial. Nevertheless, they play a crucial role in this portion of the story, and as such are included in the credits for this game.
During the prologue of his story, Wario, being very sick and in pain, retrieves Nasty Garlic from his refrigerator, believing it is regular Garlic and will help him. However, consuming the garlic contracts a few Awful Viruses, appearing in Wario's system as very small, though dangerous, cells that are green with yellow eyes and pink lips. The player is tasked with poking each dangerous virus to nullify it, turning it into a blank, circular cell lacking in energy. This strengthens the Wario Viruses, allowing them to consume the Awful Viruses and become even stronger, turning Wario into Wario-Man and beginning his respective set of microgames.
