"Cyberdark", spelled "Cyber Dark" (サイバー・ダーク Saibā Dāku) in Japanese, is an archetype of DARK Dragon and Machine-Type monsters, as well as a sub-archetype of the "Cyber" archetype. These cards were used by Zane Truesdale following his "rebirth" in the Yu-Gi-Oh! GX anime as a forbidden "Underworld Deck" (called "Cyber Art Reverse" in the original).
In the anime, the Deck's unquenchable thirst for battle and improvement forces its owner to go past his/her limit, slowly damaging the user's body over time. Because of this drawback, only Duelists with strong wills and dreams of progression can use this Deck for long periods of time. Depending on how strong-willed the Duelist is, the Duelist using this Deck will experience heart trauma, which may lead to death, as displayed by Zane Truesdale after using this Deck for so long. Even Syrus Truesdale experienced some cardiovascular pain when he decided to take over Zane's Duel against Makoto Inotsume. However, Syrus was able to overcome this problem by respecting the Deck, something that Zane had not done.
As a supporting theme, these cards can be inserted into many Dragon Decks, given there are enough Level 3 and lower Dragon-Type monsters for support (such as "Masked Dragon", "Armed Dragon LV3", "Hunter Dragon", some of the "Dragunity" cards, etc.). Alternatively, it is possible to build a "Cyberdark" Deck by using some three copies of "Hunter Dragon" and some other Dragon-Type monsters, as well as cards to send the Dragon-Type monsters to the Graveyard.
Apart from being 2000 - 2500 ATK beatsticks, "Cyberdark" monsters also works very well with Virus cards—"Eradicator Epidemic Virus", "Deck Devastation Virus", and (after the equipped Dragon-Type monster is destroyed) "Crush Card Virus". Since the effect of "Cyberdark" monsters to equip other monsters to themselves only activates when that monster is Normal Summoned, it is a good idea to return them to the hand (with "Compulsory Evacuation Device", "Relieve Monster", etc.) if their Equip Card is destroyed. "Dark Eruption" allows the player to recover "Cyberdark" monsters from the Graveyard. "Creeping Darkness" can be used to search the "Cyberdark" monsters by banishing 2 DARK monsters from the Graveyard.
Each "Cyberdark" Machine-Type monster has a different offense-based effect. Each has of the Level 4 "Cyberdark" monsters has a Trigger Effect to equip itself with a Level 3 or lower Dragon-Type monster from the Graveyard when it is Normal Summoned; it gains ATK equal to the ATK of the monster equipped by this effect, and the monster equipped by this effect is destroyed instead if the equipped monster would be destroyed by battle. The "Cyberdark" Fusion Monsters, "Cyberdark Dragon" and "Cyberdarkness Dragon", also have an effect to equip themselves with a Dragon-Type monster from the Graveyard (regardless of Level) when they are Special Summoned; it gains ATK equal to the ATK of the monster equipped by this effect.
In addition to having equipping effects, "Cyberdark Horn", "Cyberdark Edge", and "Cyberdark Keel" each have an additional effect that punishes defensive play by an opponent: "Cyberdark Horn" inflicts piercing damage, "Cyberdark Edge" can attack directly, and "Cyberdark Keel" inflicts effect damage. "Cyberdark Dragon" gains 100 ATK for each monster in its controller's Graveyard. The potency of the Deck lies with its ability to quickly Normal Summon "Cyberdark" monsters with high ATK.
"Cyberdark Cannon" and "Cyberdark Claw" are Level 3 Dragon-Type monsters, allowing them to be treated as Equip Cards by the Machine-type members. They both have 1600 ATK points, allowing the Level 4 "Cyberdark" monsters to increase their ATK to 2400. When sent to the Graveyard while equipped to a monster, its possessor can add a card to their hand (drawing in the case of "Cannon", adding a "Cyberdark" monster from the Graveyard in the case of "Claw"). Each can also be discarded from the hand to add a card from the Deck to the hand (a Machine-Type "Cyberdark" in the case of "Cannon", a Cyberdark Spell/Trap Card in the case of "Claw"). When the equipped monster battles, the player can send a monster to the Graveyard (from their Main Deck in the case of "Cannon", their Extra Deck in the case of "Claw").
Using a lower amount of "Cyberdark" monsters will require a recycling technique to keep them in the hand, which is necessary to remain aggressive. "Monster Reincarnation" can return them and discard a Dragon-Type monster at the same time, but this results in -1 hand advantage. "Dark Eruption" does this at no cost (thus results in no change in hand advantage), but is more limited in what it can target.
The Field Spell Card "Cyberdark Inferno" prevents "Cyberdark" monsters from being targeted or destroyed by opponents' card effects while equipped with a card, and also allows the player to return a "Cyberdark" monster to the hand and Normal Summon it again to change or restore the monster equipped to it. Additionally, if it is destroyed, the player can add a Polymerization/Fusion (archetype) card to their hand, giving them access to "Future Fusion" and "Overload Fusion".

"Hunter Dragon" has the highest original ATK of all Level 3 or lower Dragon-Type monsters with 1700, resulting in 2500 ATK for the Level 4 "Cyberdark" monsters. "Cyberdark Cannon", "Cyberdark Claw" and "Autovarrett Dragon" are second to "Hunter Dragon" in terms of ATK increase with 1600 ATK each. "Masked Dragon" is both an eligible target for the Level 4 "Cyberdark" monsters and can search any other eligible target except "Hunter Dragon". "Armed Dragon LV3" can be Tributed for "Armed Dragon LV5", thus sending itself to the Graveyard to then be targeted by a "Cyberdark" monster. "Magna Drago", a Tuner monster, can be used to perform Synchro Summons, which makes it an available target for "Cyberdark" monsters. "Exploder Dragon" is useful for destroying opponents' monsters. "Dread Dragon" can search for other Level 3 or lower Dragon-Type monsters when destroyed by battle and sent to the Graveyard, and is also a Tuner monster. "Red-Eyes Baby Dragon" can add a Level 1 Dragon-Type monster from the Deck to the hand when sent to the Graveyard while equipped to a monster.
"Future Fusion" is a fast way to fill up the Graveyard with Dragon-Type monsters. During the next turn after its activation, the player can reveal "Five-Headed Dragon" and send 5 Dragon-Type monsters from their Deck to the Graveyard. If "Future Fusion" remains on the field until the following turn, the player will Fusion Summon "Five-Headed Dragon", which is a powerful monster on its own.
Despite the low ATK range, the "Dragunity" archetype is suitable for "Cyberdark" Decks as they are Tuner monsters that have effects that only apply while equipped. "Dragon Mastery" can boost each "Cyberdark" monster's attack by 500, although equipping monsters to "Cyberdark" monsters with its effect does not provide the same bonuses as they gain for monsters equipped by the "Cyberdark" monsters' own effects. Level 4 Dragon-Type monsters (such as "Infernal Dragon", "Blizzard Dragon", and "Spear Dragon") are usually kept at a minimum, but are useful for their effects and to serve as targets for "Cyberdark Dragon".
- Dragunity Aklys (when a Cyberdark would be destroyed By Battle, destroys a card your opponent controls)
- Dragunity Brandistock
- Dragunity Corsesca (searches for more "Cyberdarks")
- Dragunity Partisan (for Synchro Summoning support)
- Dragunity Phalanx (to Synchro Summon faster)
- Dragunity Pilum (for direct attacks; best used with "Cyberdark Keel" and "Cyberdark Horn")

High Level Dragon-Type monsters are usually kept to a minimum, since they can only be equipped to "Cyberdark Dragon" and "Cyberdarkness Dragon". "Cyberdark" monsters are DARK monsters, so "Dark Armed Dragon" can be used effectively in a "Cyberdark" Deck. Chaos Deck-themed strategies could be applied when using "Blue-Eyes White Dragon" and "The White Stone of Legend", which could fuel the Special Summoning of cards like "Darkflare Dragon" and "Lightpulsar Dragon". When paired with "Red-Eyes Darkness Metal Dragon", the player can search for specific Dragon-Type monsters and Special Summon them from the Graveyard. This recyclable strategy could be used to swarm the field with Dragon-Type monsters for a Synchro, Xyz or Link Summon, or a simple beatdown. "Light and Darkness Dragon" can be added to the Graveyard and clears out the player's field, which can be used to send Dragon-Type monsters to the Graveyard. "Cyberdark" monsters may mix well with "Armed Dragon" Decks because of the high ATK beatsticks and because their Tribute fodder effects make them easy targets for the equip effect of the "Cyberdark" monsters. The "Malefic" archetype can be very useful to "Cyberdark Dragon", because they are fairly easy to Summon, have high ATK, and they send themselves to the Graveyard unless there is a Field Spell Card such as "Dragon Ravine" on the field, easily setting them up to power-up "Cyberdark Dragon" or "Cyberdarkness Dragon".
