The Common Cold is a recurring antagonist of Codename: Kids Next Door. He is an eternally ill villain who wishes to spread his cold to everyone else in the world and uses a machine to fire mucus from his nose at his enemies. He is also the uncle of Anna Worthington.

He was voiced by Tom Kenny who also voiced Knightbrace and Chester in the same series.


The Common Cold first appears in Operation: T.O.M.M.Y., in which Numbuh Two's brother, Tommy, aids the Common Cold out of jealousy for the KND, building a machine for him that transforms him into the "Flu Bug". Numbuh Two's mother used chicken soup to counter the machine and defeat the villain.

The Common Cold never got a starring role in an episode again, but made several minor appearances.


  • The Common Cold's weaknesses include chicken soup and Vitamin C. However, even though some products claim it does, Vitamin C does not treat or cure the Common Cold.
