Virus

A Virus is a germ enemy found in the Dr. Mario series. Viruses are highly infectious and must be neutralized quickly before they are allowed to spread. Thankfully, Dr. Mario is always on the scene to contain viruses in glass jars and eliminate them with his trusty Megavitamins.

Viruses come in three colors: red (fever), blue (chill), and yellow (weird). To defeat a Virus, Dr. Mario must line up three pills of the same color next to the Virus. The Virus, along with the Megavitamins, will then disappear. After clearing one jar of Viruses, Dr. Mario will move to the next one (with each jar containing increasingly more Viruses).

Viruses also appear in Mario & Luigi: Superstar Saga. In this game, Viruses roam the halls of Woohoo Hooniversity, Cacklettaâ€™s temporary base-of-operation. Viruses appear in all three colors and attack in groups. However, in this game, Viruses can actually change color. In fact, when hit by Mario or Luigi, a Virus will assume a different color. When two or more Viruses match in color, they will be instantaneously destroyed.

The item Driver Virus from Mario Kart Arcade GP resembles a blue virus.
