A Lingering Effect ( (ざん) (ぞん) (こう) () Zanzon Kōka) is any effect that applies even if the card is no longer on the field. Lingering effects cannot be negated (except by negating the initial effect).

One type of card which often has a "lingering" effect are the Monster Tokens. Tokens are not Effect Monsters and they do not have any effects of their own; rather, the "effects" of Monster Tokens are actually the lingering effect of the Spell, Trap or Effect Monster that Summoned it, and the tokens are always treated as normal monsters.

These effects, however, are listed as effect(s) of the Monster Tokens in video games to make their purposes less confusing.

Once applied, a Lingering Effect cannot be negated. For example, if "Limiter Removal" affects a monster, and that monster later becomes unaffected by card effects (e.g. due to the effect of "Number 81: Superdreadnought Rail Cannon Super Dora"), it will still be destroyed during the End Phase.
