Virus

Viruses are enemies that mainly appear in the Dr. Mario games. They commonly appear in Red, Blue, and Yellow varieties, and they can be only defeated by using Megavitamins matching up three of the same colors.

Other Appearances

Mario & Luigi series

Mario & Luigi: Superstar Saga

Viruses are first seen in Mario & Luigi: Superstar Saga where they are only fought in Woohoo Hooniversity. In battle, they mainly attack by trying to bite either Mario or Luigi. If this attack isn't blocked back, the Virus may poison the brother. They are also defeated when all of the viruses in each battle is the same color. Viruses are seen briefly in Mario & Luigi: Bowser's Inside Story where they are one of the Toothy's attacks.

Mario & Luigi: Dream Team

Viruses are fairly common in Mario & Luigi: Dream Team where they are seen only in the areas when Mario and Luigi are searching for the five pieces of the Ultibed, but some appear in Wiggly's area. The Viruses always fight in groups and they attack mainly by charging at Mario and Luigi. They are defeated normally or by placing them in 3 same colors in a row.

Dr. Luigi

The Viruses return in this game where they serve as the main enemies. Their designs in this game are completely different from most other games.

Dr. Mario World

The Viruses reappear in this mobile game for iOS and Android, this time wreaking havoc all across the Mushroom Kingdom, forcing Mario and his friends to team up with Bowser and his minions to bust the viruses.  In addition to the standard red, yellow, and blue viruses, this game also has green, cyan, purple, and pink viruses.
