** The outer dragons -- dragons native to the various planes of the afterlife -- include some rather unpleasant natives of [[{{Hell}} the Lower Planes]]. Hell dragons are horrific monsters in league with the devils and always seeking to damn souls to the flames of Hell, while the rift dragons of the Abyss are demonic entities who often make their way to the material plane to force mortals to worship them as demigods of suffering and destruction.

*** This version of Jack has a retrained of "Red Daemon's Dragon", which is "Red Daemon's Dragon Scarlight", which is a basically an even more destructive version of the original, but lacking the demerit of the Duel Dragon counterpart from the manga. Its evolved form "Tyrant" looks more demonic with its additional wings and additional horns, but without looking drastically different like all the other evolved forms of the other versions that preceded it.

*** The Four Heavenly Dragons themselves count, as their are able to bring out the inner darkness (Z-ARC) that is residing within their wielders, and the four dragons had a dark history in the past. Aside from that, Odd-Eyes Pendulum Dragon, which is probably the most soft-hearted of the four, uses {{Hellfire}} as its BreathWeapon, is not hesitant to inflict physical violence on duelists, and has the most demonic evolution of the four, "Supreme King Violent Dragon - Odd-Eyes Raging Dragon". "Dark Rebellion Xyz Dragon" is a black and purple dragon that brutally pierces the enemy with its pointy chin that is charged with lightning, and if combined with "Odd-Eyes", they become the very aggressive "Supreme King Black Dragon - Odd-Eyes Rebellion Dragon" that tears the enemies apart with its lightning-charged tusks. "Clear Wing Synchro Dragon" is actively looking for the other dragons to force them into fights, and "Starve Venom Fusion Dragon" is a horrific dragon with man-eater plant attributes that can swallow other monsters whole or even eat humans, and "Starve Venom's" Fusion Materials require them to be two DARK monsters. All four gain corrupted forms known as "Supreme King Servant Dragons", acting as Z-ARC's elite squad of four powerful dragons that protect "Z-ARC" while he also protects them with his mere presence alone. In order to beat "Z-ARC", the characters have to beat him alongside his Four Heavenly Dragons at once.

** ''Manga/YuGiOhR'': The Wicked God counterpart to "Osiris the Heaven Dragon" is "The Devil's Eraser", a very demonic-looking dragon that gains power depending on the number of cards the opponent is holding in their hand. What makes this monster really powerful is its TakingYouWithMe effect, as it can kill and destroy everything on the field (including other Gods) if "Eraser" is destroyed. "Eraser" is capable of destroying itself on command, meaning that it doesn't to have to wait for opponent to destroy it to trigger its other effect.

** Giratina, first introduced in [[VideoGame/PokemonDiamondAndPearl Gen IV]], is the third member of the creation trio, a Ghost/Dragon type who was banished to the Distortion World by Arceus for its violence, and has a particularly evil-looking appearance, though it isn't inherently evil.
*** ''VideoGame/PokemonLegendsArceus'' would take this trope up a notch by showing how ''terrifying'' a Giratina can be, especially [[spoiler:in the hands of the BigBad Volo.]]

*** The ultimate BigBad is "Supreme King Dragon Z-ARC", who is the combined form of Zarc and the Four Heavenly Dragons. Z-ARC is a gigantic black dragon that is hellbent on destroying the world to fulfill the people's craving for violence. Because of that, Zarc is referred to as the Devil Duelist and he can still duel even in his dragon form.
