Face off against the final boss!— TCG commercial for Mystic Fighters
The "Generaider" theme appears to be based on miscellaneous myths and figures of Norse mythology.
"Generaider" seems to be a pun on the word "generic", given the use of this archetypes in decks matching their type. This, combined with how some cards reward the opponent for slaying the deities, could be akin to that of a boss fight in an RPG.
Most monsters in this archetype have a Level/Rank of 9, which is likely a reference to the Nine Worlds of Norse cosmology. Each monster has the symbol from the artwork of "Generaider Boss Stage"; each of the Level/Rank 9 monsters have one of the circles in this symbol highlighted a certain color, in order to represent which of the nine worlds they originate from.
|Monster||Reference||Highlighted circle||Highlight color||World of origin|
|Frodi||Light elves||Upper middle||Light yellow||Álfheim|
|Utgarda||Utgard||Upper right||Light blue||Jötunheimr|
The "Generaider" playstyle revolves around quickly getting the Field Spell, "Generaider Boss Stage", to the field and utilizing its effects to summon a free "Generaider" monster from the Deck whenever the opponent draws a card, including in the Draw Phase, accompanied by up to 4 "Generaider Token" monsters. From there, you are able to destroy/tribute 1 or more "Generaider" monster(s) and/or monsters that share the same Type as the monster on field for the effects of the various "Generaider" monsters on the field. These effects range from mass Special Summoning from the hand with the Machine monster "Dovelgus, Generaider Boss of Iron", singular GY revival with the Zombie monster "Hela, Generaider Boss of Doom", destruction protection with the Beast-Warrior monster "Naglfar, Generaider Boss of Fire", Special Summon negation with the Wyrm monster "Nidhogg, Generaider Boss of Ice", and targeted mass monster destruction and drawing with the Warrior monster "Frodi, Generaider Boss of Swords". The only exception to this is the Plant monster "Mardel, Generaider Boss of Light", who searches a "Generaider" card or a Plant monster on Normal or Special Summon.
From there, the deck is built to play a control situation of using Tokens for effects and swarming the field in Level 9 monsters in order to make powerful Rank 9 Xyz Monsters and/or Link Monsters; such as the boss monster of the deck, the Rank 9 "Jormungandr, Generaider Boss of Eternity", as well as Rank 9 "True King of All Calamities" and even "World Gears of Theurlogical Demiurgy".
