Virus

A Virus is a germ enemy found in the Dr. Mario series. The Viruses started attacking at Mushroom Kingdom Hospital. During this time, Dr. Mario was on the scene to contain the Viruses in glass jars and eliminate them using Megavitamins.

Physical Appearance
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 of that color. 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).

Dr. Mario
The three Viruses first appeared in the NES and Game Boy game Dr. Mario, where they are little germs that Dr. Mario must eliminate. To do this, he uses Megavitimins, which can come in red and blue, red and yellow, red and red, yellow and yellow, blue and yellow and blue and blue. Four of these vitimins must be stacked on top of a virus of the same color to eliminate it. As the difficulty increases, so do the number of viruses.

Dr. Mario 64
The viruses appears again in Dr. Mario 64, and they play the same role as before. The way to beat them stays the same too.

Dr. Mario & Germ Buster
Viruses also appeared in the WiiWare game Dr. Mario & Germ Buster, where they obviously acted like they did in Dr. Mario. They were also seen fighting Miis in the Germ Buster game.

Mario & Luigi: Superstar Saga
Viruses also appear in Mario & Luigi: Superstar Saga. In this game, Viruses roam the halls of Woohoo Hooniversity, Cackletta's temporary base-of-operation. Viruses appear in all three colors and attack in groups. However, in this game, Viruses can change color. In fact, when hit by Mario or Luigi, a Virus will assume a different color. When all the current Viruses in-battle match in color, they will be instantly destroyed, somewhat similar to the way they are defeated in Dr. Mario.

Mario & Luigi: Bowser's Inside Story
The Blue Virus makes a minor cameo in Mario & Luigi: Bowser's Inside Story. After knocking out all the body segments of a Toothy, the Toothy attacks by spitting out a Blue Virus holding a spear to attack the player.

In the Toadley Clinic's lobby, there is a sign on the wall that shows a blue Virus in a red circle with a "/" through it (similar to a "no smoking" or "no pets" sign).

Mario Kart Arcade GP
In Mario Kart Arcade GP, the item, Driver Virus, is a Blue Virus. In this game, the Virus has swirly eyes.

WarioWare series
In WarioWare, Inc.: Minigame Mania, one of 9-Volt's microgames is based on the game Dr. Mario, and the player must defeat the Viruses using Megavitamines, just like in the game. In WarioWare: Twisted! in the microgame Weird Science, a blue Virus makes an appearance. Also, in WarioWare: Touched!, some of the viruses from the microgame Rock Fever look similar to the viruses from Dr. Mario.

Nintendo Comics System
The Viruses appeared as the main antagonists in Nintendo Comics System's adaptation of Dr. Mario entitled "The Doctor Is In... Over His Head". It was this appearance that named the Red Virus Fever, the Blue Virus Chill, and the Yellow Virus Weird.

In the same episode, the Viruses are given special powers: Chill can manipulate the cold, Fever can control heat, and Weird can forcibly morph others into different shapes and creatures.



Club Nintendo
Two Viruses can briefly be seen inside Bowser's stomach in the Club Nintendo comic "Süße Weihnachten". They symbolize his sickness after having eaten too much.
