"Subterror" (サブテラー Sabuterā) is an archetype of EARTH monsters that first appeared in The Dark Illusion. It is one of two formerly TCG-exclusive archetypes that premiered in that set, the other being the "SPYRAL". The archetype includes a sub-archetype called "Subterror Behemoth".


All members of this archetype are EARTH monsters. The archetype's higher Leveled "Subterror Behemoth" sub-archetype is comprised of colossal beasts whose names are a reference to subterranean anomalies or types of rock. The lower Leveled monsters comprise the "Subterror Nemesis" sub-series, who are human hunters fighting the "Subterror Behemoths".

The announcement of the archetype's first Extra Deck monster, "Subterror Behemoth Fiendess", revealed that "Subterror Fiendess" is a "Subterror Behemoth" in disguise, sharing the same hair and wing design, and both having "Fiendess" in their name.

Playing style

The effects of the two "Subterror Nemesis" monsters are very necessary in order to Special Summon the "Subterror Behemoth" monsters from the Deck face-up or face-down. Since "Subterror Nemesis Warrior" has the ability to be continually re-used, it is common to see the cards "Speedroid Terrortop" and "Speedroid Taketomborg" being used to Xyz Summon "M-X-Saber Invoker" simply to search it out. "Tour Guide From the Underworld" with any Level 3 Fiend-Type monster or "Predaplant Ophrys Scorpio" with "Predaplant Darlingtonia Cobra" can have the same result, with the ability to search "Instant Fusion" if using the "Predaplant" engine.

Flipping the "Subterror Behemoth" monsters face-up and face-down can be controlled through card effects such as "Prediction Princess Tarotrei", "Book of Taiyou", "Subterror Final Battle" and "The Hidden City".
