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 each one represents one of the eight main tribes. Once unsealed, these Yo-kai will start off at Lv. 1.

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


 * In Yo-kai Watch 3: Sushi and Tempura, a new category of Legendary Yo-kai are introduced, noted as the "Great Legendary Yo-kai". The game also introduces a brand new set of Legendary Yo-kai, some of them being "Merican Legendary Yo-kai".

Summoning 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.

Yo-kai Watch

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


 * The English lyrics are: "Imaginary Incendiary Flip flop Squiggleboom slim slam Legendary!"

Yo-kai Watch U
In the anime and when playing with the toys, their chant is:.

Trivia

 * Without resorting to exploits in the first game, Shogunyan is the only Legendary Yo-kai that can be obtained during the course of the main story, with the others having at least one Yo-kai who can only be obtained 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.
 * Elder Bloom has Dromp and Castelius Max (though the needed Platinum Bar to evolve Castelius I can be obtained before post-game via a completed Yo-kai Cam challenge or the Golden Egg event).
 * Dandoodle has Everfore and Insomni.
 * 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, both of the Brave medals have the same designs, and both of the Tough medals also have the same designs.
 * Elder Bloom: Two Medals from the Heartful, Slippery, Shady, and Tough tribes. Unlike Komashura, the order is preserved for the later four Medals.
 * Dandoodle: All Medals are from the Eerie tribe.
