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 spawns a World-Healing Wave which brings everyone he killed back. Most versions of Warrior Heaven also have the dead get back up at the end of the day so they can continue feasting and fighting.
Remember, this is a full resurrection. If you are looking at bringing back a whole bunch of zombies then Night of the Living Mooks is for you. Or if you need help from some allies, but don't have this trope at hand, then the Cavalry of the Dead may be just what you needed.
- In Naruto, one of the many powers of the Rinnegan is this. However, there is a catch; resurrecting someone is very chakra-taxing and can potentially kill the user if done on a large-scale basis. Nagato performs the jutsu to resurrect everyone killed during the Akatsuki's invasion of Konoha (including Kakashi, Shizune, and Fukasaku), but dies shortly afterward. This despite the fact that he is an Uzumaki, whose claim of fame is longevity. Later, Obito Uchiha attempts to use it to resurrect people killed during the Fourth Ninja World War, which would surely kill him due to the scale of the event, but gets his body hijacked by Black Zetsu and forced to resurrect Madara Uchiha instead.
- 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 Secret Wars:
- Doctor Doom steals the Beyonder's power and kills all the heroes. His lackey Klaw (who secretly is possessed by the Beyonder at the time) talks Doom into thinking about the heroes reviving & attacking, and given that the Beyonder had Reality Warper powers which Doom stole this becomes true.
- In the second series the Beyonder killed and later resurrected the New Mutants.
- In the Marvel Comics Crisis Crossover The Infinity Gauntlet approximately half of the universe is killed, but they're resurrected by the end of the series.
- In the MLP:FIM/World of Warcraft crossover World of Ponycraft Princess Celestia resurrects almost all of Ponyville at once after Neltharion razes it.
- In The Sorcerer's Apprentice, this is Morgana's final goal: to resurrect a legion of Sorcerers for world domination.
- In Avengers: Endgame, the heroes' main goal is to find a way to reverse the Decimation, essentially bringing back half of all life in the universe. They succeed, but the resurrection only applies to victims of the Badass Fingersnap, meaning that everyone who died before or after the Snap stays dead. Also, two of their number die over the course of the film.
- The Bible:
- In Book of Ezekiel, God commands Ezekiel to resurrect a whole army of skeletons into living beings in order to reclaim Israel.
- According to the Book of 1st Thessalonians, a mass resurrection of "the dead in Christ" shall occur. They will then be swept up to heaven along with the believers that still live.
- According to the Book of Revelation, God will do this on the Last Day to everyone who had ever lived, raising them from the dead just before the Judgment.
- Even prior to Christianity, some Jews (e.g. the Pharisees) believed this would happen, and some still do.
- Islam, too, teaches a mass resurrection will happen before God judges all human beings.
- Perhaps the Trope Maker is Zoroastrianism, whose teachings first held that a mass resurrection and then judgment would occur when Ahura Mazda defeated his evil rival Ahriman. Some scholars believe this belief influences the Jews (who were liberated by the Persians from the Babylonian Captivity) then the Christians and Muslims in turn. Regardless, it's grown in popularity obviously.
- Dungeons & Dragons
- 2nd Edition supplement Book of Artifacts. The silver Orb of Dragonkind could resurrect 20-200 bodies once per year.
- Module T1-4 Temple of Elemental Evil. If the deity St. Cuthbert is summoned, he will Raise all slain PCs from the dead with a gesture.
- In early editions of the game, the Wish spell was able to resurrect a group of characters.
- In Pathfinder, one monk variant has the ability to do this for all of their fallen allies in exchange for completely wiping themselves out of existence (subverting Death Is a Slap on the Wrist), making them not just Deader Than Dead, but an Un-person to the point where even their name disappears from where it was written down.
- World of Warcraft
- This ability is a guild perk.
- Also used by Terenas Menethil II on the raid after his son, Arthas aka the Lich King, kills the players.
- 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.
- In Overwatch, Mercy's original ultimate ability Resurrect allowed her to resurrect all nearby allies who hadn't respawned yet. The original "Huge Rez" achievement was achieved when she resurrected four or more allies at once. On 19/9/2017, her Resurrect was changed to a normal ability which can only resurrect up two people in a short amount of time (if Valkyrie was used to reset the cooldown), so it is now a heavily downplayed version of the trope.
