"Malefic", known as "Sin" (Sinシン Shin) in the OCG, is an archetype of cards which were introduced in the Yu-Gi-Oh! 3D Bonds Beyond Time movie. They are used by Paradox, and are almost exclusively corrupted versions of existing monsters.

Both "Malefic Paradox Dragon" and "Malefic Stardust Dragon" appears as characters in Yu-Gi-Oh! 5D's World Championship 2011: Over the Nexus.


Paradox claims that they are the most powerful cards in history, due to the fact that they aren't bound to Normal Summoning rules.

In the movie, "Malefic" monsters were much more flexible than their OCG/TCG cards; multiple "Malefic" monsters could exist on the field at once, they did not impose attack restrictions on their controller and the original monsters were sent to the Graveyard (instead of being banished), thus allowing Paradox to easily and constantly swarm the field with his powerful monsters.


Designs of "Malefic" monsters


The Japanese name for this archetype, "Sin", is meant as a pun on the words for "truth" ("shin") and "sin" ("tsumi"), alluding to the truth of human nature as seen by Paradox - that humanity's errors have led to the world's destruction.

The English name "Malefic" means "having or asserting a negative influence", referring to how these cards are corrupted versions of existing cards.


Many "Malefic" monsters have mechanical-looking pieces of their body which are made of a mix of white, grey and black metal, including wings and face-plates (and, in the case of "Malefic Stardust Dragon", knee and torso plates). Their faces have masks similar to that of Paradox, with the right side black, the left side white and line patterns that cover the eyes ("Malefic Cyber End Dragon" also has its far right head black and far left white). "Malefic Blue-Eyes White Dragon" and "Malefic Red-Eyes Black Dragon" are the only "Malefic" monsters whose right eye is not covered by their masks.


Most of the monsters in this archetype are corrupted versions of other monsters (most of which are counterparts of well-known Dragons). The remaining four monsters look similar, but have no known non-Malefic counterparts.

Playing style[edit]

The basic, underlying playstyle of a "Malefic" Deck is an Aggro Beatdown Deck that focuses on constant Special Summoning of high Level DARK monster with high ATK. Most "Malefic" monsters are Special Summoned by banishing their original counterpart from the hand, Deck or Extra Deck (varies by monster) while a Field Spell Card is active.

"Malefic World" is the Deck's primary Field Spell Card, acting as a method to search "Malefic" cards at the cost of the Normal draw, allowing the "Malefic" player to avoid dead draws of monsters that need to be banished for the Summoning conditions of their "Malefic" monsters, as well as setting up "Malefic Truth Dragon" to act as a hand trap.

Due to the Deck's reliance on constantly controlling a Field Spell Card, "Terraforming" is essential, and additional Field Spell Cards—such as "The Seal of Orichalcos", "Magical Citadel of Endymion", "Dragon Ravine" and "Geartown"—are recommended. "The Seal of Orichalcos" and "Magical Citadel" both have self-protection, "Dragon Ravine" allows sending "Truth Dragon" to the Graveyard, and "Geartown" allows the player to maintain field presence even if it is destroyed by Summoning "Ancient Gear Gadjiltron Dragon" (which can also be discarded using "Trade-In" to add consistency to the Deck).

"Malefic Stardust Dragon" offers support to the archetype by protecting Field Spells from destruction by card effects as well as being very easy to Summon (as "Stardust Dragon" is banished from the Extra Deck). "Malefic Rainbow Dragon" and "Malefic Cyber End Dragon" act as the Decks main and easiest to Summon beatsticks. "Malefic Parallel Gear" is the archetypal Tuner, which uses a "Malefic" monster from the hand as the non-tuner for the Synchro Summon, allowing "Malefic Paradox Dragon" (or another Level 10 Synchro Monster such as "Dragocytos Corrupted Nethersoul Dragon") to easily be easily Summoned.

"Red-Eyes Darkness Metal Dragon" can be used to revive "Malefic Blue-Eyes White Dragon", "Malefic Red-Eyes Black Dragon" and "Malefic Paradox Dragon". If a Field Spell, except "Malefic World" is on the field "Paradox Dragon" will be destroyed, thus allowing the usage of "Malefic Truth Dragon" repeatedly. Additionally, using cards such that prevent Setting (such as "Dark Simorgh") or cards that cause piercing (such as "Dragon's Rage") can be used to take full advantage of the high ATK of "Malefic" monsters.

By using a combination of "Ojama Trio"/"Nightmare Archfiends" and "Battle Mania"/"All-Out Attacks" "Malefics" can easilly achieve an OTK.

With new era support, the archetype becomes vastly better. The addition of "Malefic Territory" removes the inability to control multiple "Malefic" monsters whilst providing protection to "Malefic World" if activated from the deck and giving more reason to use said Field Spell, albeit while removing access to "Truth Dragon’s" effect. "Malefic Paradox Gear" also adds to the searching capabilities of the deck allowing the player to not only immediately gain access to more protection such as "Malefic Stardust", but also start earlier with "Parallel Gear" for an immediate Synchro play. "Paradox Gear" can also replace main deck requirements such as vanilla "Rainbow Dragon" for access to more beatsticks. "Malefic Selector" adds yet another layer of searching though it restricts the player from searching the same monsters banished and with the same name as each other. "Malefic Divide" is also essentially a Quick-Play "Monster Reborn" for the archetype. And finally, "Malefic Tune" can be used in a pinch for more draw and yet more searching although it’s status as a Trap Card makes it slower and more likely to be destroyed.

Official Deck[edit]


  • In the trailers shown before every episode[citation needed] are nine face-down cards. The first 5 are the "Malefic" monsters that were corrupted versions of original Dragons. The sixth is "Elemental HERO Neos Knight", the seventh is "Junk Gardna", the eighth is "Malefic Parallel Gear", and the ninth is "Malefic Paradox Dragon".
    • All of these cards featured prominently in the movie. The "Malefic" monsters have also appeared in alternate versions of the FREEDOM and -OZONE- animations that used footage from the film.
  • All "Malefic" Spell/Trap Cards in Japanese have their names printed in English.
  • "Malefic" monsters share some traits with two other 5Ds Era archetypes used by antagonists; "Earthbound Immortals" and "Meklord Emperors".
    • "Earthbound Immortal": Both archetypes consist of DARK Attribute monsters, they are (for "Malefic" most are) Field-Unique and destroy themselves if a Field Spell Card is not present.
    • "Meklord Emperor": They share an effect which prevents other monsters you control from attacking.
