Card Trivia:Doom Virus Dragon
- This monster has the same effect as "Crush Card Virus" before its erratum.
- This monster is possibly based on the Guivre, since in the anime, this monster attacked by spraying the opponent with filthy water, and used vines to destroy the opponent's monsters, while the Guivre was said to inhabit forests, lakes, and marshy areas.
- This card is the first "The Fang of Critias" Fusion Monster, as well as the first overall "Legendary Dragon" Fusion Monster, to appear in the anime.
- It is also the only "The Fang of Critias" Fusion Monster whose Level is not 8.
