Union monsters are a special type of Effect Monster with (Type)/Union in their card text. They can function like an Equip Srd, and thus become vulnerable to cards that destroy Spell Cards, such as Mystical Space Typhoon. They equip to the host Monster their text designates and generally grant it additional strength, such as an increase in ATK/DEF. Earlier Union Monsters Destroy themselves tould be destroyed by battle while equipped. More recent Union Monsters, though, such as Heavy Mech Support Platform, Spirit of the Six Samurai and Armored Cybern, also protect the host Monster from any kind of Destruction.

Union Monsters can either Equip or Unequip to the host once per turn with their own Effect, given they are on the field. Additional cards, such as Formation Union and Combination Attack allow them to Equip and Unequip alternatively. Some Union monsters fuse with their hosts, ex 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 Union Monsters introduced the XYZ Archetype (which would later become the VWXYZ Archetype), which had a new way of using their Fusion Monsters. This unorthodox method involves removing the Fusion Material Monsters from play to Special Summon the Fusion Monster from the Extra Deck (This is not considered a Fusion Summon). Polymerization cannot be used to Fusion Summon these monsters.

After a prolonged absence, Union Monsters have made a comeback in Structure Deck 18: Machiners Command, which introduces a number of new Union Monsters, including Machina Gearframe, with the highest ATK of any level 4 or lower Union Monster in the game, and Machina Peacekeeper, who can search another Union Monster out of your deck when destroyed, whether in monster or Equip Card form. While neither grants anything to their equipped monster besides destruction protection, their uses outside of being equip cards are a great asset to decks that incorporate Union Monsters.

After a prolonged absence, Union Monsters have made a comeback in Structure Deck 18: Machiners Command, which introduces a number of new Union Monsters, including Machina Gearframe, with the highest ATK of any level 4 or lower Union Monster in the game, and Machina Peacekeeper, who can search another Union Monster out of your deck when destroyed, whether in monster or Equip Card form. While neither grants anything to their equipped monster besides destruction protection, their uses outside of being equip cards are a great asset to decks that incorporate Union Monsters.

Union Monsters can be recognized by the fact that, where on an ordinary Effect Monster it would read 'Effect', Union Monsters have 'Union'. Cards such as Dark Necrofear, Kiseitai or Armory Arm act as Equip Spell Cards but do not have the text designating them Union Monsters; the latter of the forementioned three can even become a monster again.

Union monsters are a special type of Effect Monster with (Type)/Union in their card text. They can function like an Equip Spell Card, and thus become vulnerable to cards that destroy Spell Cards, such as Mystical Space Typhoon. They equip to the host Monster their text designates and generally grant it additional strength, such as an increase in ATK/DEF. Earlier Union Monsters Destroy themselves to protect the host Monster if it would be destroyed by battle while equipped. More recent Union Monsters, though, such as Heavy Mech Support Platform, Spirit of the Six Samurai and Armored Cybern, also protect the host Monster from any kind of Destruction.

Union Monsters can either Equip or Unequip to the host once per turn with their own Effect, given they are on the field. Additional cards, such as Formation Union and Combination Attack allow them to Equip and Unequip alternatively. Some Union monsters fuse with their hosts, ex 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 Union Monsters introduced the XYZ Archetype (which would later become the VWXYZ Archetype), which had a new way of using their Fusion Monsters.

Earlier Union Monsters Destroy themselves to protect the host Monster if it would be destroyed by battle while equipped. More recent Union Monsters, though, such as Heavy Mech Support Platform, Spirit of the Six Samurai and Armored Cybern, also protect the host Monster from any kind of Destruction.

Union Monsters can either Equip or Unequip to the host once per turn with their own Effect, given they are on the field. Additional cards, such as Formation Union and Combination Attack allow them to Equip and Unequip alternatively. Some Union monsters fuse with their hosts, ex 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 Union Monsters introduced the XYZ Archetype (which would later become the VWXYZ Archetype), which had a new way of using their Fusion Monsters. This unorthodox method involves removing the Fusion Material Monsters from play to Special Summon the Fusion Monster from the Extra Deck (This is not considered a Fusion Summon). Polymerization cannot be used to Fusion Summon these monsters.

After a prolonged absence, Union Monsters have made a comeback in Structure Deck 18: Machiners Command, which introduces a number of new Union Monsters, including Machina Gearframe, with the highest ATK of any level 4 or lower Union Monster in the game, and Machina Peacekeeper, who can search another Union Monster out of your deck when destroyed, whether in monster or Equip Card form. While neither grants anything to their equipped monster besides destruction protection, their uses outside of being equip cards are a great asset to decks that incorporate Union Monsters.

Union Monsters can be recognized by the fact that, where on an ordinary Effect Monster it would read 'Effect', Union Monsters have 'Union'. Cards such as Dark Necrofear, Kiseitai or Armory Arm act as Equip Spell Cards but do not have the text designating them Union Monsters; the latter of the forementioned three can even become a monster again.

Union monsters are a special type of Effect Monster with (Type)/Union in their card text. They can function like an Equip Spell Card, and thus become vulnerable to cards that destroy Spell Cards, such as Mystical Space Typhoon. They equip to the host Monster their text designates and generally grant it additional strength, such as an increase in ATK/DEF. Earlier Union Monsters Destroy themselves to protect the host Monster if it would be destroyed by battle while equipped. More recent Union Monsters, though, such as Heavy Mech Support Platform, Spirit of the Six Samurai and Armored Cybern, also protect the host Monster from any kind of Destruction.
