Aka: Guyver three, aka Dark Guyver, aka. Zeus

Data: Agito is ruthlesly power hungry, he refers to life as a game or a play and will stop at nothing to gain absolute power.

Agito was the adopted son of his uncle, the former head of Chronos Japan, Genzo Makashima and through working for him, Agito gained the nessessary power he needed to start his war on Chronos, his first act being ensuring the death of Genzo Makashima.

Since then he remained a mole inside Chronos until he had no choice to blow his cover, when Dr. Balkus was going to engineer him into a hyper Zoanoid.

Now Guyver Three uses the Gigantic upgrade armour, to lead his army of Zoanoids (Zeus' Thunderbolt, created by Professor Yamamura) and his allie Zoalord Shizu to war against the Zoalords at the Arizona base where an important Relic is kept.
