Card Appearances:Ring of Destruction

"Ring of Destruction":

Yu-Gi-Oh!

In manga, this card's effect is "Activate only when an opponent's monster declares an attack. This card becomes an Equip Card equipped to the attacking monster then destroy that monster and inflict damage to that monster controller equal to the destroyed monster's ATK". Because that, Kaiba doesn't need Ring of Defense.

Seto Kaiba uses this card in his tag duel against Lumis and Umbra, his duel with Noah Kaiba, and during the four-way duel between himself, Yugi Muto, Yami Marik and Joey Wheeler. Each time he combined it with Ring of Defense. Kaiba used the card without the Ring of Defense against Dartz.
This card can be seen in Kaiba's hand during the battle royal in 122.

In Yu-Gi-Oh! GX, Bastion Misawa used this card in his entrance exam duel, destroying his Vorse Raider and wiping out the rest of the proctor's life points.
This card belongs to Bastion which Chazz Princeton threw this card into the water in episode 12.
During Bastion's duel with Jaden, this card is shown as one of the ten cards piled on top of Carboneddon in Bastion's Graveyard. He discarded a card when he summoned Mathematician, but it wasn't revealed what it was until later. Via process of elimination, it had to have been this card.
Later on, Chazz uses this on Gyaku-Gire Panda and protects himself with Ring of Defense while the North Academy students are wiped out.
In Chazz's first duel with Alexis Rhodes, he destroys her Blade Skater when she attacks his Ojama Yellow, using this card.
This card appears in the GX Japanese closing song, Borderline Battle.
