[[Jaden Yuki]] mentions that the King of Games, [[Yugi Muto]], faced many Shadow Duels and triumphed; the fact that Yugi took part in Duels involving magic thus appears to be common knowledge in ''GX''.<ref>{{episode|Yu-Gi-Oh! GX|28|ref}}</ref> During Jaden's first Duel against [[Nightshroud]], he realized that Shadow Duels really existed; having not believed in them prior.<ref name=GX29>{{episode|Yu-Gi-Oh! GX|29|ref}}</ref> Unlike the Shadow Duels in the ''[[Yu-Gi-Oh!]]'', which were invoked with a [[Millennium Items|Millennium Item]], these Duels were invoked by [[Duel Monster Spirits|spirits of Duel Monsters]] or by [[Shadow Charm]]s.<ref name=GX29/>

The [[Dark Signers]] are capable of turning Duels into Shadow Duels. When a Dark Signer engages in a Duel, the arena is surrounded by a forcefield of lightpurple fire, taking the shape of the Dark Signers' corresponding [[Nazca Lines|Nazca Line]] and becomes a Shadow Duel. When a brainwashed Dark Signer servant engages in a Duel, the arena is instead surrounded by a circle-shaped purple glowflame. When a brainwashed person Shadow Drone loses a Shadow Duel the [[Mark of the Shadows|Dark Signers' mark]] disappears and they return to their original state.

Shadow Duels are damaging to the Duelists and the blasts from the attacks can be fatal and often cause damage even to the surrounding observers and area; [[Jack Atlas|Jack]] and [[Tetsu Ushio|Trudge]] destroyed half a hospital. The Nazca Line shape around the area viciously tears up any objects in its path as it forms.

A '''Shadow Turbo Duel''' is a derivation of a normal Shadow Duel against a Dark Signer. It possesses all the characteristics of basic Shadow Duels, except that it occurs within the rules of a [[Turbo Duel]]. Like normal Shadow Duels, all impacts coming from monster attacks and effects are real. This results in the possible damaging of a [[Duel Runner]] as occurred to [[Yusei Fudo]].

However, in the last Shadow Turbo Duel that occurred between Yusei, Jack and Crow versus [[Rex Goodwin]], Goodwin remained at the top of altar of the [[Stairway to the Dragon Star]], while Yusei, Jack and Crow drove their Duel Runners on the track formed by Goodwin's Condor geoglyph. This is the only Turbo Duel so far in which someone is not on a [[Duel Runner]] or a [[Duel Board (5D's)|Duel Board]], but as with a Duel Board, as long as someone has a "[[Speed World (anime)|Speed World]]" card they can use a Duel Disk.

In ''[[Yu-Gi-Oh! ARC-V]]'', while there is no direct mention of Shadow Duels, but some elements are utilized in the [[Action Duel]] concept, in which the use of [[Solid Vision]] causes monsters to be physically materialized and landscapes changed according to the Action Field selected. Real damage is inflicted through shockwaves, and although harmful, they are not shown to be lethal. Noteworthy is that Duelists are allowed to physically assault the opponent, although such practices are rare.  Shadow Duels have been were implied when [[Yuto]] and later [[Shay Obsidian]] inflict inflicted damage without the use of an Action Field, though ; this appears is later implied to be a function of their Duel Disks. The only apparent mystical forms and is seen commonplace through the remainder of shockwaves have occurred when [[Yuya Sakaki]] Summons "[[Odd-Eyes Rebellion Dragon (anime)|Odd-Eyes Rebellion Dragon]]"the series. The most prominent method that strongly correlates with that of a Shadow Duel are the Duels initiated by members of [[Duel Academy (ARC-V)|Duel Academy]] or users of [[Human Sealing Technology]], where the losing player is sealed in a card. The only mystical elements to Duels seen in the series are when [[Zarc]] or his [[Dimensional counterparts|fragments]] Duel; the shockwaves that they can cause are far stronger than normal and have been conjured outside of Duels.
