Duel 009 cards
A number of Monster Cards that appear on the counter at Kame Game as Sugoroku explains the rules of Duel Monsters to Yugi and his friends in Chapter 9. The only ones with visible names were "Summoned Skull", "Hell-Bound", and "Rock Man". Another card from this scene appeared, labeled only as an "ally," as a character in the dice game included with Volume 3.

Yugi's Duel 010 cards
A number of unnamed monsters played by Yugi during his first Duel with Seto Kaiba 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."

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

Yugi's Death-T monsters
A number of monsters played by Yugi during his final showdown with Kaiba at Death-T. The first three seen are all destroyed by Kaiba'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.

Kaiba's Death-T monster
A turtle-like monster Kaiba 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.

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

Ventriloquist of the Dead's monster
A one-eyed monster played by the Ventriloquist of the Dead during his Duel with Yugi. It likely originally belonged to Kaiba's Deck.

Mai's opponent's monster
A monster played by a Duelist Kingdom opponent of Mai Kujaku's in the manga, which was destroyed by Mai's "Harpie Lady Sisters", winning Mai the Duel.

Jonouchi's monsters
The first is a knight-like monster played in Defense Position during Jonouchi's Duel with Ryuzaki in the manga.

The second was used in Jonouchi's Duelist Kingdom Duel against Kaiba.

Chicken
In the manga, a Level 3 chicken-like monster was shown, while the Meikŷu Brothers explained the rules of the Labyrinth Duel.

Pegasus' monster
During his final Duel with Yugi in the manga, Pegasus uses this monster along with "Dark-Eyes Illusionist" to Ritual Summon "Relinquished." "Relinquished" resembles a combination of "Dark-Eyes Illusionist" and this card. In the anime, Pegasus uses "Dark-Eyes Illusionist" alone for the Ritual Summon.

As it met the conditions for "Black Illusion Ritual", it is an Illusion monster and has less than 100 ATK.

Ryuzaki's monster
During his Duel with Esper Roba in the manga, Dinosaur Ryuzaki used this monster. Roba put it to sleep with "Mesmeric Control", before destroying it with "Jinzo". In the anime, it is replaced with "Serpent Night Dragon".

Battle City participants' monsters
Two generic Battle City Duelists were shown using these two cards, one of which is a dragon, while the other is a knight.

An aerial view of another Duel showed another three unnamed cards.

Nagumo's opponent's card
A Duelist defeated by Koji Nagumo used this card. Koji won it through the ante rule, but demanded another rare card, as he thought its value did not compare to the card he wagered, "Hyozanryu".

Pandora's monster
A pumpkin-headed monster of Pandora's that he sacrifices along with Yugi's "Beta the Magnet Warrior" by way of "Coffin of Dark Resurrection" to Summon "Dark Magician", in the manga. In the anime adaptation, he uses "Mystic Tomato" instead.

Bakura's card
A card seen in Dark Bakura's hand during his Battle City Duel with Dark Yugi, in the manga, depicting a poltergeist. It is unspecified whether this is a Monster, Spell or Trap Card. It is hypothesized to be "Spiritualism", based on both cards' artworks and the Japanese translated name of "Spiritualism", "Poltergeist".

Yako's monsters
A trio of monsters used by Yako Tenma as Tributes to Summon "The Wicked Avatar" during his first Duel with Yugi.

Jaden's opponent's monster
This monster was used by an unnamed opponent of Jaden Yuki and was destroyed by Jaden's "Elemental Hero Bubbleman".

Axel's cards
These cards are seen in Axel Brodie's hand alongside "Electro Sergeant" in his Tag-Team Duel with Jim Crocodile Cook against Alexis Rhodes and Bastion Misawa.

Aster's monster
Aster Phoenix used this monster against Alexis Rhodes. It was destroyed by Alexis' "Blizzard Princess", allowing Aster to move the "Vision Hero Increase" in his Graveyard to this Spell & Trap Card Zone since he took battle damage.

Jim's monster
Jim Crocodile Cook used this monster against Bastion Misawa. He Tributed it alongside "Spawn Alligator" to Tribute Summon "The Tyrant Neptune". The effect of "The Tyrant Neptune" makes its own ATK the combined value of the Tributed monsters. Its ATK here was 3800, implying that this card's ATK was 1600, since the ATK of "Spawn Alligator" is 2200.

Kalin's monster
A monster used by Kalin Kessler while he was a teen in the manga.

Gorilla monster
A gorilla-like monster wearing a spiked shoulder harness used against Leon von Schroeder in a flashback. It is destroyed by the effect of Leon's "Seven Kids," winning Leon the Duel.
