The later members are spun off the original card, "Crush Card Virus". "Crush Card Virus" is a Virus Card in the manga. Somewhat ironically, "Crush Card Virus" no longer has the Lingering Effect of other "Virus" cards in the TCG/OCG due to receiving a major errata so that it did not need to be Forbidden. However, the monster counterpart of "Crush Card Virus", "Doom Virus Dragon", has the same effect that it did prior to its errata.
All members of the series have the following properties in common:
- They are Normal Trap Cards (except in manga that Virus Cards exist).
- The activation cost is Tributing a monster that meets a certain restriction.
- Upon resolution, it destroys opponent's cards that meet a certain condition.
- Until the opponent's 3rd turn after it was activated, its Lingering Effect has a negative effect on the opponent (except for "Crush Card Virus" after its major errata).
