Army of the Ages



One of the standard uses of Time Travel for an Evil Overlord is to pluck warriors from various wars throughout history and bring them through to the future (the Evil Overlord's present) and assemble them into an unbeatable army.

Occasionally, more heroic entities will use this as a means of recruiting a Time Police force.

When an army is made up solely of recognised historical figures, that's an Archived Army. And if a group of dead people are brought together to pass judgement on the living, that's a Jury of the Damned.

Anime & Manga

 * The Fourth Ninja War arc of Naruto features heavy use of a resurrection jutsu that brings back a wide range of ninja that had been previously killed. Everything from past villains the protagonists had faced to legendary ninja who had been dead for decades.
 * In Mahou Sensei Negima,

Comic Books

 * Reinhold Borsten did this in the Hex comic book series. This is how gunslinger Jonah Hex got transported to 2050.
 * The 2008 DC Comics mini-series The War That Time Forgot centered on this, with various characters from DC's war books dragged through time and dropped on Dinosaur Island. (The series is in fact named after one of the features from one of those comics that took place on Dinosaur Island.)
 * Inverted in X-Men, where Fitzroy tries to conquer the present (his past) with future sentinel technology. It finally backfires spectacularly when he opens a portal to a prison riot in the future, bringing in a horde of mutant inmates — Bishop follows.
 * The Avengers's foe Kang once had his own team of elite warriors plucked from different time periods, The Anachronauts.
 * Kang and his counterparts have also employed the Legion of the Unliving, made up of time-plucked characters who are thought dead in the present.
 * A notable example is during Avengers Forver were Kang allies with the Avengers to fight a Army of the Ages sent by his older self Immortus.

Film

 * The title characters do this to battle Satan in Time Bandits.
 * Night At the Museum's schtick in a nutshell. Note that "hero" and "villain" are subjective: Custer may be remembered as Evil Is Hammy, but he's still a hero in the show. Alongside Sacajawea.

Literature

 * This is the setting for Fritz Leiber's Change War stories, but the stories are all told by grunts who have no understanding of the big picture.
 * Neal Asher's book Cowl features a Roman Legionnaire, an assassin from a cyberpunk future and a Neanderthal on the same team.
 * The Tamuli has the bad guys doing this. But it's less effective than most examples as the Army of the Ages are usually bronze age soldiers who are up against knights in full plate.
 * Edward Eager's Knight's Castle has a variation: the protagonists, four children, have been shrunk to a tiny size and the world of their toy knight figurines has come alive. They win the day in the end by bringing in one child's collection of toy soldiers, which includes soldiers from several different historical wars.
 * Nearly any military force in the Riverworld books is this trope, by nature of the series.
 * Percy Jackson and The Olympians has an example, but it isn't time-travel related. The fortress of the Greek god Hades is guarded by dead soldiers from all of history: Skeletal Roman legionnaires with spears are joined by undead US Marines with assault rifles.

Live Action TV

 * The War Lord does this in the Doctor Who serial "The War Games".
 * In the episode "A Good Man Goes to War",
 * Star Trek Voyager does a scaled down version of this when the ship is broken into multiple time frames. In order to remove Seska and the Kazon from engineering (it being the time they took over the ship in that section), Chakotay recruits Icheb and Naomi from the future, Torres and some Maquis from the day they arrived in the Delta Quadrant, Janeway and Kim from before the mission began, Paris from the relative present, and finally the still-Borg Seven of Nine.

Tabletop Games

 * Eternity's Rangers from GURPS: Time Travel.
 * Heroscape
 * The basic premise of the Magic the Gathering CCG, with you as the summoner.
 * The SPI board game Time Tripper allowed you to play a Time Tripper, who went forward and backward in time to recruit soldiers as allies.
 * In Scion, the Einherjar warriors that show up in modern times come from the 18th century through the mid-1970s, outfitted in whatever gear they had on them when they "died".

Video Games

 * This is the plot of the recent first-person shooter Darkest of Days. Well, the organization that recruits you out of the American Civil War apparently isn't evil, and is more of a Time Police. But they still do most of their recruitment by plucking skilled soldiers out of various wars throughout history, namely people who were considered 'missing in action' anyway.
 * The Fallout 3 expansion "Mothership Zeta" has you team up with several cryogenically-preserved warriors on the alien spaceship: a military doctor from Operation Anchorage, a contemporary slaver, a wild west cowboy, and a samurai. And a little girl from during the Great War.
 * You also would've had an astronaut, but he didn't survive the thawing process.

Western Animation

 * Common in many Hanna-Barbera cartoons. Standard villainous armies tend to include Goths, Mongols, Vandals, and the like.
