You have a large number of characters whom have been killed and you need to bring them back to life for some reason or another.
Then this trope is for you!
Maybe you can ask a powerful healer, pray to a God, or maybe the defeat of the Big Bad spawn a World-Healing Wave which brought everyone he killed back.
Remember, this is a full Resurrection. If you are looking at bringing back a whole bunch of zombies then Nightofthe Living Mooks is for you. Or if you need help from some allies, but don't have a this trope at hand, then an Armyofthe Dead may be just what you needed.
In Naruto, it seems this is one of the abilities of a person who possesses the Rinnegan as long as they have enough Chakra to do so.
In Dragon Ball Z, the Earth Dragon can revive a virtually limitless number of people at one time, with some restrictions. At one point, it is used to revive everyone killed by Frieza in the past year, or on his orders, which effects a staggering number of people, including most of the population of the planet Namek.
In Warcraft 3, the Paladin's ultimate ability resurrects up to six of your own dead units at full health (if their corpses are still around, that is.)
High Inquisitor Whitemane, the final boss in the updated Scarlet Monastery, uses an interruptible version of this.
The Necron Lord in Dawn of War can bring back a large number of Necron infantry in an area around him, using an ability 'called' Mass Resurrection.
In the end of Planescape: Torment, the Nameless One can manage to resurrect his entire party who have all suffered a Plotline Death in the final dungeon if certain pre-conditions are met.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
