Immortal

Immortal is a monster Type that does not exist within the official OCG, but rather exists within the game . In this game, Immortal-Type monsters, regardless of ATK, can move in and out of Crush Terrain freely, and when destroyed, turn the surrounding spaces into Crush Terrain, often destroying the attacking monster as a result.

Some resemble machines of some sort, while others take on the appearance of strange creatures related to liquids. The Immortal-Typing can also be used to represent creatures that are mysterious, ancient, mystic, and - most importantly - cannot be classified under any other regular Type. This can include deformed abominations, spiritual beings that cannot be classified Fairy or Fiend-Type, monsters which are considered abnormally powerful while still not being strong enough to warrant the Divine-Beast-Typing, and other general monsters that cannot fit other categories.

All Immortal-Type monsters from ''Yu-Gi-Oh! The Duelists of the Roses'' have a counterpart in the OCG/TCG, except "".
