"Archfiend", known as "Daemon" (Japanese: デーモン Dēmon) in the OCG, is one of the very first archetypes. Members appear in a myriad of sets due to the string required for inclusion being a simple word in Japanese. While many Duelists use "Archfiend" cards in the anime and manga as a result, only Titan runs a dedicated "Archfiend" Deck. The majority of the monsters in this archetype are DARK Fiend monsters, but there are many monsters of other Attributes and Types. The "Red Dragon Archfiend" archetype is a sub-archetype of the "Archfiend" archetype.
