The Trifecta of "Ium" follow a naming scheme, they all have "Ium" at the end of their names. * Vitrium (defacto leader, Underwater specialist) * Piviorium (Demolitions specialist along with Santium, Air Specialist, Defacto Second in Command) * Santium (Demolitions specialist also,Scout and spy, medic, and Land Specialist) They form the Tripod blade. All minicons that transform into weapons have some scheme (I know this since I looked on TFwiki. Fact.), so they have "Air, Land, and Water", but also "Ground Vehicles".
