Subterror

"Subterror" is an archetype that first appeared in The Dark Illusion. It is one of two TCG-exclusive archetypes that premiered in that set, the other being the "SPYRAL" archetype.

While all members of this archetype are EARTH, each one have an unique Level and Type. It includes the "Subterror Behemoth" sub-archetype.

Design
The "Subterror" archetype is a combination of the "Subterror Behemoth" monsters - colossal beasts whose names are a reference to subterranean anomalies or types of rock - and the "Subterror Nemesis" monsters, who are human hunters who confront them.

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 Darling 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", and "The Hidden City".
