Mirror Universe Monster

A  is a monster that is a counterpart of an existing, classic monster that appears in Yu-Gi-Oh! BEYOND.

Definition
A Mirror Universe Monster is often a monster that counterparts a classic monster of the past Yu-Gi-Oh! series, usually ''Yu-Gi-Oh! Duel Monsters and Yu-Gi-Oh! GX, but monsters from Yu-Gi-Oh! 5D's'' can be classified as Mirror Universe Monsters if they fall under the following criteria:
 * 1) It is of an "opposite" Attribute. If the classic monster is DARK, your Mirror Universe Monster must be LIGHT and vice-versa. If the classic monster is WATER, your Mirror Universe Monster must be FIRE and vice-versa. If the classic monster is EARTH, your Mirror Universe Monster must be WIND and vice-versa.
 * 2) It has a different Type from the original monster, often having an opposite meaning. For example, while "" is a  monster which represents magic, "Blinding Weaponmaster" is a   monster, which represents might. An equal relation happens for  monsters, whose Mirror Universe Monster is often a  monster.
 * It, or the archetype which is centered around it, often has a different, if not opposite, mechanic than the original. An example is "Crimson Gazer Coatl", a DARK Wyrm Mirror Universe counterpart to "". While a "Blue-Eyes" deck contains mostly Fusion and Synchro Monsters, the "Crimson Gazer" archetype, which "Crimson Gazer Coatl" falls in, uses Fusion and Dark Synchro Monsters, with the Tuner "with Eyes of Blue" monsters being transformed from Tuners to Dark Tuners.
 * 1) They have mirrored ATK and DEF compared to the original monster. For example, "Blinding Weaponmaster" has 2100 ATK and 2500 DEF, as opposed to 2500 ATK and 2100 DEF of "Dark Magician".

This is an open project, and is not restricted to any one cardmaker.

Trivia

 * This idea was first used by AvzinElkein, as he is the creator of "Blinding Weaponmaster", "Material TYRANT Palaios" and "Voidsteam Dragon". In August 2017, LHK ideated an archetype system and formed the definition of the term "Mirror Universe Monster", in agreement with Avzin.
 * In Yu-Gi-Oh! BEYOND, users of Mirror Universe Monsters are often villains or anti-heroes, as the decks were often made by either the Neo Gymnastic Group or the Foulementals. The first exception was in the case of Tina Humphries, who used that deck since her childhood.
 * In Yu-Gi-Oh! BEYOND, Mirror Universe Monsters are considered to be descendants of legendary monsters, often resembling in appearance. Because of the setting of Yu-Gi-Oh! BEYOND is set in the 23th century, the "original" monsters are considered to be monsters of legend.
