Pretty faithful design I thought and the grafted tech on the back certainly is in keeping with the original story. For reference... Original: A product of the Omegaton Corporation's DNA testing of select immigrants for a large some of money if they survived. These mutants are what remain after the test subjects escaped the labs of Omegaton Corporation during a raid to expose the myths about this new product/creature that claimed to help soldiers on the battlefield. Calamusiod can still reproduce but have a degenerating DNA and each new generation is mutated in a different way, causing these creatures to be very hostile towards humans. Latest: Genetically-engineered creature with a bionic inhalation-feeding system - hence the lack of a mouth. Elite Warlord Using a canister on its back the female elite Calamusoid has the ability to launch the toxic waste-products of its bionic feeding system at an attacker. Subject SH-10 & SH-30 In addition to launching toxic substances at an attacker using a canister on its back, the Super Heavyweight class of Calamusoid can brutally decapitate oncomers using a heavy chain wrapped around its clubbed hand.
