Yugi's Duel 010 cards
A number of unnamed monsters played by Yugi during his first duel with Seto in an attempt to stall his opponent's powerful "Megamorph"-equipped "Battle Ox," including a bird/fishlike creature and a bald, tattooed figure. All are quickly destroyed by "Battle Ox."

Seto's Duel 010 monster
A magician-looking monster played by Seto during his first Duel with Yugi.

Yugi's Death-T monsters
A number of monsters played by Yugi during his final showdown with Seto at Death-T. The first three seen are all destroyed by Seto's powered-up "Saggi the Dark Clown," while the fourth appears in Yugi's hand. The second and third monsters seen are replaced by "Chimæra" and "Gremlin" respectively in the first series anime adaptation of the manga duel.

Seto's Death-T monster
A turtle-like monster Seto played in Defense Position during his Death-T duel with Yugi during the time his "Blue-Eyes White Dragons" are immobilized by Yugi's "Swords of Revealing Light." It appears in both the manga and the first series anime.

A spherical, insect-like monster Yugi played in Defense Position during his duel with Insector Haga in the manga.
