ZX-Tole commands Hyper-Zoanoid Team Five, an elite Chronos Corporation unit engineered by Dr. Barcas as the pinnacle of Hyper-Zoanoid combatants. His biomechanical beetle form integrates thirteen bio-blasters, retractable wings, a thermal abdomen-mounted Blaster Tempest rivaling a Guyver’s Mega-Smasher, and a horn-concealed secondary cannon. Disguised as a stocky, round-featured human with cropped hair, he masks his lethal capabilities.
Debuting in the Mt. Minakami conflict, ZX-Tole baits Guyvers by abducting Fumio Fukamachi, overpowering Guyver III through relentless barrages and armored resilience. His squad fractures when the rogue Lost Number Aptom infiltrates Chronos, consuming teammates Thancrus, Elegen, and Gaster. A desperate clash with Aptom forces ZX-Tole to sever his own leg to survive—a sacrifice nullified as Aptom assimilates the limb, replicating its power.
Post-Chronos’ global domination, Dr. Barcas rebuilds him as Neo ZX-Tole, fusing fallen allies’ enhancements into a Lost Number upgrade. This iteration wields electromagnetic arcs, napalm vents, and micro-explosive darts, alongside Aptom-targeting antibodies and metabolic viruses. The modifications accelerate cellular decay but amplify lethality. During Tokyo’s siege, Neo ZX-Tole channels solar energy into a suicidal Final Blaster Tempest, halted only by Guyver Gigantic’s countering Giga-Smasher, which annihilates him.
The 1990 OVA alters his fate: after Guyvers I and III decimate his team, ZX-Tole absorbs Elegen’s residual energy, morphing into a gold-armored "Ultimate" form with invulnerable plating and intensified firepower. Though this fusion destabilizes his lifespan, he endures a direct Mega-Smasher before twin blasts from Sho and Agito penetrate his defenses, erasing him.
All versions depict ZX-Tole as a tactically brilliant, vengeance-driven force, leveraging raw strength and loyalty to Chronos and his unit. His relentless pursuit of retribution against Aptom and the Guyvers cements his threat, yet rigid tactics amidst evolving foes ensure his repeated downfalls.
