Lists

Union monsters (ユニオンモンスター Yunionmonsutā) are Effect Monsters with the ability "Union". Each Union monster has an effect that allows it to equip itself to a monster as Equip Spell Card or unequip itself to Special Summon itself to a Monster Zone.

Not all monsters that can treat themselves as Equip Cards are Union monsters; for example, "Worm Millidith", "Dark Necrofear", "Kiseitai", "Armory Arm", and "Number 58: Burner Visor" all have effects to treat themselves as Equip Cards, but none of them are Union monsters.

Some Union monsters and their Union monsters can be used as Fusion Materials to Summon particular Fusion Monsters (e.g. "V-Tiger Jet" and "W-Wing Catapult" to form "VW-Tiger Catapult", or "Dark Blade" and "Pitch-Dark Dragon" to form "Dark Blade the Dragon Knight").

The equip-themed "Vylon" and "Machina" archetypes contain several Union monsters.

Effects

Every Union monster has an Ignition Effect that allows it to either equip to or unequip from the host once per turn while it is on the field. If a Union monster unequips itself with its own effect, it is Special Summoned; Union monsters last printed prior to Structure Deck: Seto Kaiba can only be Special Summoned in Attack Position if Summoned this way. Additional cards, such as "Formation Union" and "Combination Attack", can equip and unequip Union monsters, with "Formation Union" even treating the Union monster as having been equipped by its own effect.

They also do not require you to Special Summon them in Attack Position after being unequipped from a monster.

Older Union monsters have an effect to destroy themselves if the monster they are equipped to would be destroyed by battle. More recent Union monsters destroy themselves if the monster they are equipped to would be destroyed by any means. All Union monsters printed since Structure Deck: Seto Kaiba (including reprints) destroy themselves if the monster they are equipped to would be destroyed by battle or card effect.

Prior to Structure Deck: Seto Kaiba, all Union monsters had a condition that meant that only one Union monster could be equipped to a monster at a time. In the OCG, from Structure Deck: Seto Kaiba onward, Union monsters no longer have this restriction (including reprints).

Text

The most recent Union card text in the TCG reads as follows:
Once per turn, you can either: Target 1 [X] you control; equip this card to that target, OR: Unequip this card and Special Summon it in Attack Position. While equipped by this effect, [...] (A monster can only be equipped with 1 Union monster at a time. If the equipped monster would be destroyed [by battle], destroy this card instead.)

Based on Official Proxies from Seto Kaiba Structure Deck, the new TCG text will be as follows:
Once per turn, you can either: Target 1 [X] you control; equip this card to that target, OR: Unequip this card and Special Summon it. [...] If the equipped monster would be destroyed by battle or card effect, destroy this card instead.

Trivia

  • Newer Union monsters tend to combine with Machine-Type monsters and are Machine-Type themselves.
  • Currently, there are no Union Monsters with more than 2000 ATK or DEF.
