Duel Armor is the armor Yami Yugi and Yugi received in Yu-Gi-Oh! Capsule Monsters. The armor has the ability to fuse with any monster.
By fusing with a monster, it heightens the wielder's physical abilities, including: enhanced strength, speed, reflexes, leaping, agility, balancing, stamina, endurance and durability. However, activating the armor will leave the wielder fatigued for a while as a side-effect; but Yami Yugi and Yugi were able to master the armor without tiring themselves out for a while.
Monsters Yami Yugi fused with:
- Dark Magician
- Magician of Black Chaos into Magician of Black Chaos (armor)
- Black Luster Soldier into Black Luster Soldier (armor)
- Blue-Eyes White Dragon
- Seiyaryu, Thunder Dragon, Curse of Dragon and Red-Eyes Black Dragon into Armor of Unity
Joey Wheeler has also fused with:
- Red-Eyes Black Dragon (While he was under the influence of the Blade of Chaos in episode 7. Since the Blade of Chaos was removed, Joey could no longer fuse with key monsters.)
Alexander the Great also possessed a Duel Armor which fused him with Reshef the Dark Being.
