Legendary Yo-kai

The are a select group of powerful Yo-kai that can only be befriended after filling out Legend Pages in the Yo-kai Medallium, which is done by collecting certain sets of Yo-kai Medals to break the seal surrounding a particular Legendary Yo-kai, with each seal requiring a different set of 8  Medals, which vary depending on the game series.

All Yo-kai in this group are Rank S Yo-kai, and there exists at least one Legendary that represents the eight main tribes. Once unsealed, these Yo-kai will start off at Lv. 1.

Five of these Yo-kai were the first to be introduced in the first Yo-kai Watch video game, representing the Brave, Mysterious, Heartful, Eerie, and Tough tribes.
 * In Yo-kai Watch 2: Bony Spirits and Fleshy Souls, three more Legendary Yo-kai representing the Charming, Shady and Slippery tribes were introduced, completing the set of the eight tribes


 * In Yo-kai Watch 3: Sushi and Tempura, 3 more Legendary Yo-kai representing the Brave, Charming, and Eerie tribes were introduced. In addition, 2 new subcategories of Legendary Yo-kai are introduced, noted as the Great Legendary Yo-kai and the Merican Legendary Yo-kai.

Summoning Song/ Chant
Legendary Yo-kai, despite falling to a pre-established tribe, have unique summoning chants which plays instead of the regular ones. These chants are very bombastic and grandiose compared to the normal Yo-kai Tribes.

In the anime and when playing with the toys, their chant is: "Imaginary! Incendiary! Flip flap, squiggle doodle, slim slam, Legendary~!"

In the anime and when playing with the toys, their chant is:.

Yo-kai Watch Model Zero
Along with the originally introduced Yo-kai Tribes, the Legendary Yo-kai's chant with the Yo-kai Watch Model Zero in the anime and when playing with the toys has replaced with instrumentals, with the Legendaries getting a bombastic orchestra line. When set at the 2 setting however, the normal summoning fanfare is a bombastic brass cover.

Yo-kai Watch U
In the anime and when playing with the toys, their chant is: with a orchestra accompaniment and sung by a choir. Like the Model Zero Yo-kai Watch, the ending is slightly altered, with sounds of celebration at the ending.

Yo-kai Watch Dream
In the anime, the summoned Yo-kai will play a roulette game to determine if they get a lucky or unlucky summon.

Trivia
The Brave tribe has the most legendary yo-Kai, (including Great Legends and Merican Legends) with 4, funnily enough 3/4 are Cat Yo-Kai.
 * In the first game, Shogunyan is the only Legendary Yo-kai that can be befriended during the course of the main story, with the others having at least one Yo-kai who can only be befriended post-game. Gilgaros is the exemption, due to how all Yo-kai needed to summon him are Crank-a-kai-exclusive Yo-kai, and thusly relies solely on luck.
 * Komashura has Kyubi.
 * Dandoodle has Everfore and Insomni.
 * Elder Bloom has Dromp and Castelius Max (though the needed Platinum Bar to evolve Castelius I can be befriended before post-game via a completed Yo-kai Cam challenge or the Golden Egg event).
 * Dandoodle in the anime is the cheapest Legendary Yo-kai ever summoned, requiring 6 Yo-kai Medals to summon him rather than the traditional 8. This would later be used as the normal amount needed to summon Legendary Yo-kai in Yo-kai Watch: Wibble Wobble, due to that game not including every Yo-kai.
 * The first five Legendary Yo-kai required Yo-kai Medals in the first game are all arranged to form into distinctive patterns.
 * Shogunyan & Gilgaros: One Medal for each Yo-kai tribe.
 * Komashura: Two Medals from the Charming, Brave, Mysterious, and Tough tribe, with the later four done in reverse order. Incidentally, both of the Charming medals are of the Koma-inu family and both the Brave and Tough medals have the Yo-kai share the same designs.
 * Dandoodle: All Medals are from the Eerie tribe.
 * Elder Bloom: Two Medals from the Heartful, Slippery, Shady, and Tough tribes. Unlike Komashura, the order is preserved for the later four Medals.
 * The 5 originally released Legendary Yo-kai featured in Yo-kai Watch: Wibble Wobble had their Legend Page Seals be slightly abridged versions of their seals present in Yo-kai Watch 2.
 * Shogunyan's Wibble Wobble Legend Page removed Buhu and Dismarelda, despite both Yo-kai being present in the default version of the game.
 * Komashura's Wibble Wobble Legend Page removed Geki Dragon and Hiraishin, both who are currently unavailable in Wibble Wobble.
 * Dandoodle's Wibble Wobble Legend Page removed Lie-in Heart and Tattlecast, despite both Yo-kai being present in the default version of the game.
 * Elder Bloom's Wibble Wobble Legend Page removed Don-chan and Dromp, both who are currently unavailable in Wibble Wobble.
 * Gilgaros' Wibble Wobble Legend Page removed Damona and Eterna, despite both Yo-kai being present in the default version of the game.
 * Yo-kai Watch 3 features the first instance of version-exclusive Legendary Yo-kai, with Asura being available to only Tempura players and Otohime being available to only Sushi players.
