The Evil That Lies Within (5)

Cypheroid

The tissue sample previously taken from Tendril grows into a second Tendril monster but is contained soon enough thanks to Earth Corps. The creature is then seized by Senator Masterson, who orders it placed in captivity to be studied by an advanced supercomputer, Cypher. The computer ends up freeing the Inhumanoid instead, exhibiting its own acquired sentience, soon rebuilding itself into the improved Cypheroid using technology stolen from Earth Corps. The rogue A.I. then directs Tendril to free Metlar. It also arranges for Blackthorne Shore to be released from prison along with his cellmate, the diabolical Dr. Herman Manglar, who has the fatal misfortune of encountering a pool of haphazardly discarded toxic waste during their swampy escape. The pursuit takes Earth Corps underground where the Cypheroid is ultimately destroyed, but Metlar remains at large, almost annihilating Earth Corps if not for the meddling of Blackthorne.
