Infernity

The Infernity cards are an Archetype used by Kyosuke Kiryu.

They are primarily a series of DARK Fiend-Type monsters whose effects are activated only when the player has no cards in their hand. Their name is a combination of the words, "Infernal" and "Infinity". "Infernity Archfiend", "Infernity Dwarf", and "Infernity Guardian" were released in the card game as promotional cards in the DS game Yu-Gi-Oh! 5D's Stardust Accelerator. Infernity Destroyer was released in the Yu-Gi-Oh! 5D's Stardust Accelerator - World Championship 2009 Game Guide in Japan and "Infernity Beast" was released in Ancient Prophecy.

They are currently the 2nd Dark Signer Archetype to be released, after the Earthbound Immortals themselves.
