When the original Battle Tank went into Dimension-X to locate his successor and daughter he was captured by the demonic Deathseed on his planet of Deathworld. Rex Dexter was rescued by Dragon and his family and returned to Earth but not unaffected. Something had begun slowly transforming Rex’s body into an ever-demonic looking form. His aggression seemed to increase and he became obsessed with rebuilding the damaged portal to Dimension-X, his actions alarming even his closest allies.
When Rex’s body was impaled by a girder from the destruction of Dragon’s family home, the hero’s brain was removed and placed into his Battle Tank armor. The original body was preserved in a stasis chamber for years as Rex searched for a way to regenerate it so that he could regain an organic form. The chamber was later destroyed when Emperor Kurr and Vanguard fought in Rex’s laboratory. The apparently lifeless corpse suddenly awoke and Monster Rex fled through the portal into Dimension-X and vanished without trace.
Some time later, Monster Rex emerged back through the portal with an army of Absorbanoids to lay claim to Earth. Monster Rex revealed that he was actually a resurrected Deathseed. A seed had been planted in Rex Dexter’s body back during his previous incarceration in Dimension-X. A transformation began to re-create Deathseed but Rex’s body was damaged, preventing Deathseed’s return until much later. Monster Rex’s attempted conquest of existence was halted when Rex killed his own original form, presumably ending the threat of Deathseed.
