Gondor Calls For Aid / Anime & Manga

• The Dark Masters arc of Digimon Adventure, and the last episodes of Digimon Adventure 02 and Digimon Data Squad, although it's kind of an accident.
  • Digimon's most insane use of this trope, however, is the climax of Digimon Next, where literally every single character the kids and their Digimon have met who isn't dead (and even a few who are) show up to help against the Final Boss, ranging from The Mentor to background characters to even the surviving villains. Unfortunately for them, said final boss verges on The Omnipotent, so he simply obliterates them all in one shot and the entire dimension while he's at it, leaving only the main characters alive. He's ultimately beaten simply be being convinced by the protagonists that he's wrong, and he restores everything and everyone he destroyed.
  • May be outdone by Digimon Fusion, where the second arc ends with every single Digimon in existence arriving to join the Combined Energy Attack Humongous Mecha.
• In the anime adaptation of the Ben-To light novel series, Sen Yarizui, The Ice Witch, calls upon the Western District Wolves to defend the Western District Supermarkets against an imminent invasion from a gang of Eastern District Wolves, The Gabriel Ratchets. Whilst normally wolves fight alone and against one another for their half-priced dinners, Yarizui is able to use her reputation as an especially powerful and feared fighter to have the quarrelling Wolves to unite against the oncoming threat.
• The Anime Adaption of Black Cat pulls this trope in the final few episodes. When Eve is kidnapped by Mason in order to activate the Eden Project, Train calls on literally every other surviving character (More than fifty) to aid in the rescue. Whilst the original call extends out to the remaining Chronos Numbers and the Sweepers Alliance, word spreads and Train and company eventually receive assistance from the likes of the rogue Apostles of the Stars, the kids from Leon and Tim's hideout, and later even Creed and Echidna.
• The final Best Student Council arc, where nearly every minor character who showed up once and got named returned to help the titular student council.
• Mermaid Melody Pichi Pichi Pitch always brought in the secondary trio, Kaito, and that season's orange princess in the end, even though throughout the series, they were either useless, unawakened, incapacitated or unwilling to do the job.
• Dragon Ball:
  • In the climactic battle with Kid Buu in Dragon Ball Z: Vegeta, and later Goku, continuously asks the people of Earth to raise their arms and lend some of their energy to his Spirit Bomb. Because they can't see Goku and don't know who he is, and the few people who do lend their energy end up really exhausted afterwards, only the Dragon Team and some of Goku's old friends from the original Dragon Ball (Jingle Village, Upa and Bora) as well as Android 17 lend their energy. It takes Hercule/Mr. Satan, the Fake Ultimate Hero of the Dragon Ball world, to convince the population to lend their strength.
  • Dragon Ball Super: In the ultimate call for aid, Goku recruits many of his past allies from throughout the series to help fight in the Tournament of Power, along with one nemesis.
• While not exactly calling for direct aid, Eyeshield 21 has Every ace from every important team in Kantou show up to help the Devil Bats train for the Christmas Bowl finals.
• When it comes down to the final battle in Violinist of Hameln.(pictured◊), a truly ridiculous amount of reinforcements show up (including just about every minor character capable of taking to the field).
• In Naruto, the Leaf Village gets the Hidden Sand Village to help them bring Sasuke back when he leaves Konoha for Orochimaru. Later, in Shippuden, its the Sand Village's turn to call for aid when they need to rescue the Kazekage.
  • The Raikage does this by issuing calls for an immediate summit of the Kages to discuss the threat of Akatsuki. With the threat posed, he insists that all the vilages must unite. He had previously ignored these very warnings from Konoha, and only acted when his own brother was lost.
• Inverted in The Law of Ueki. The Smart Guy Friendly Enemy Kilnorton calculates the odds of defeating Big Bad Anon to be suicidal and thus refuses to participate in the Final Battle. For the sake of his True Companions, however, he convinces Ai to make him fall in love with glasses in order to bring him to the arena despite what his better judgment says. She succeeds and Kilnorton joins in on the action. Subverted when Anon knocks him out before he can actually do anything to help.
• The final battle of Vandread brings back every character and civilization that ever displayed the ability to pilot a spaceship.
• In Durarara!!, Mikado calls on everyone online at the Dollars website to help rescue Anri from the Yellow Scarves
• The last episode of the hentai title Meiking, every group Cain helped (or spared) along the way showed up to assist in the final showdown with Cain's evil rival, Francis.
• In Fairy Tail, Ichiya calls upon the Light Guilds of Fiore to aid Fairy Tail against the Alverez Empire.
• In Tengen Toppa Gurren Lagann episode seven, a number of characters (such as Kittan and Dayakka, amongst a bunch of newly introduced folks like the twins) arrive to help the Gurren-Dan capture what will become the Dai-Gurren. They stay around afterwards, however, and permanently expand the Gurren-Dan.
• Towards the ending of My-Otome, BOTH sides in the final battle call upon reinforcements in the form of Otome from other nations, all seen briefly way back in episode three. And once the final battle breaks out, the teachers and entire student body of Garderobe comes to help the heroes.
  
  Happens in the manga too. When the real Princess Mashiro resurrects herself and dark versions of the Himes from the prequel, the protagonist(s) get help from Garderobe, the other nations, and even Shwartz in fending them off so Manshiro can get to the castle for the Final Battle.
• In the OVA series Golden Boy's final episode, Kintaro Oe calls upon each of the women whose hearts he'd won in previous episodes for the finale in which he works for an anime production company (they each had talents to offer).
• In the final episodes of G Gundam, all the Gundams of the world unite to help the Shuffle Alliance defend Earth. Naturally, they include nearly all the opponents the main cast has fought up to this point (and creating a Mythology Gag since several others are based upon past series Gundams; including an early appearance of Wing Gundam), all putting aside their differences to defend the world they love.
• Gundam Build Divers Re:RISE features a video game equivalent. Alus transports his last combat fleet from Eldora to try and attack GBN directly so he can keep the BUILD DiVERS from interfering with his long-obsolete mission of protecting the planet. How do the game staff respond? Declare an event mission, which results in a massive horde of players descending in a swarm looking for a chance at XP and loot. Players ranging from world-champion aces and social media personalities down to rookies and nameless scrubs answer the call to battle. Completely unprepared for wildly diverse opponents and the dedication of players with a chance for a prize and no fear of death due to respawn mechanics, Alus' flagships are sunk without inflicting any noticeable damage in return and his invading army of copycat Gunpla are wiped out entirely.
• Hoshin Engi: In the final battle, Genshi Tenson does a ritual to open up the Hoshindai and release all of the souls of the characters who were sent there to lend their soul energy to Taikobo/Fukki and confront Joka.
• Pokémon:
  • Near the climax of the G/S/C Story Arc of Pokémon Adventures, things were looking grim for the Pokédex Holders as they're fighting a losing battle against both Ho-oh and Lugia. Just then, they noticed something in the distance. Bill had finally fixed the Pokémon Transporter that the new Team Rocket had sabotaged, and with the director of Goldenrod Radio spreading the news, every single minor character introduced in the arc (and even some from the RGBY arc, meaning that it's likely every trainer in the Johto and Kanto regions) had sent their Pokémon to help the heroes, producing a huge-ass army that rushed the two Legendaries and quickly tamed them.
  • A more minor example happens in Pokémon: Diamond and Pearl Adventure!. Several gym leaders team up with Hareta to help defeat Team Galactic.
  • In the finale of Pokémon: The Series's XYZ arc, all of the Gym Leaders team up with Ash and his friends together to stop the Zygarde rock monster.
• Ties into Write Back to the Future in Rave Master when Sieg Hart, in the past, writes letters to all of Haru's friends so that they arrive to supply much needed support in the final battle. How he knew when the battle would occur...
• Happens during the climax of Sailor Moon Super S. The Senshi need to use the Golden Crystal to defeat Nehelania, but when Sailor Moon tries to do so, she fails to activate its power. Nehelania reveals that the power source of the Crystal is the beautiful dreams of humanity...but mankind has lost the power to have those dreams, depriving the crystal of its power. Helios insists this isn't true, prompting Chibi-Moon to use the Crystal to call on all the people of the world with beautiful dreams to lend the power of those dreams to them. And, in a montage showing almost every character previously targeted for having beautiful dreams, they do just that, breaking Nehelania's spell over the Earth and repowering the Crystal.
• In Fullmetal Alchemist, when Ed and Al call on the help of all their friends from places they've been (like Briggs) and from friends (like Izumi) to help them defeat the Homunculi and Father in the Final Battle.
• The Pretty Cure All Stars movies (and other Pretty Cure movies since Yes! Pretty Cure 5 GO!GO!) have this in terms of the Miracle Lights. It also doubles as Audience Participation, since the movie goers are given their own Miracle Lights when they go into the show.
• Transformers: Cybertron in the final battle against Galvatron, the Autobots are joined by the forces of Velocitron, Jungle Planet, Gigantion and the Decepticons under Lugnutz leadership.
• Raynesia does this in episode 18 of Log Horizon. She offers to go to Akihabara to ask the adventurers directly for help in defeating the goblin armies after talks between the nobles and adventurer leaders goes nowhere. Although she doesn't think anyone would seriously help, they're all smitten by her speech and looks, as well as being hyped up for a major event/quest in the game. As a result, practically everyone present volunteers.
• In Girls und Panzer Der Film, Oarai does not call for aid themselves, even when facing being on the wrong end of a Curb-Stomp Battle...but St. Gloriana does. And on the big day, Oarai starts out with eight tanks against thirty... until all their former rivals come charging in to join their team, bringing the Oarai team up to even numbers and making it a fair(er) fight.
• Shimoneta provides a Well-Intentioned Extremist example. For the first eight episodes, SOX manages to foil the Public Morals Committee and the student council at Tokioka Academy. Anna finally accepts that she can't stop them on her own, so she tearfully calls her father, Matsukage, for help. The scene shifts to his office as he assures her he's sending one of his best. The camera pans left, revealing Oboro standing behind him.
• Kemono Friends: The Lucky Beasts call in most of the Friends to help battle the black Cerulean in episode 12.
• Gintama in the Four Devas Arc had Otose hospitalized by Jirocho and with Gintoki losing his duel to him. Thus, the remaining Four Devas decide to tear down Otose's Snack Shop which is also the Yorozuya's home, and Saigou is forced to go with it. As the Yorozuya defends against all of them, everyone within the Kabuki District they encountered and helped through out the series lend in their aid to defend their home, and eventually have the other two Devas turn against Kada, who masterminded the operation.
• The Mysterious Cities of Gold: In episode 33, "The Reunion", the various villages are convinced to help the Village of the New Sun fight the Olmecs.
• Kamisama Minarai: Himitsu no Cocotama: The 75th episode has Kokoro's Cocotamas and Nozomi's Cocotamas recruit every minor Cocotama that has appeared in the series thus far so that they can all use their magic to help Vivit recover from a coma she fell into in the previous episode after attempting to use a forbidden spell to ascend to godhood without training.
• Miss Kuroitsu from the Monster Development Department: Despite technically being villains themselves, in the season finale, Agastia calls in help from heroes and villains alike to help defend against a hostile takeover.
