"When little brats bother me like this, they die."
Zato-1 has been a fighter in the Guilty Gear series since its inception. He was originally an assassin who shared his body with a sentient, parasitic form of life called Eddie. In Guilty Gear, Zato-1 controls Eddie's actions and uses it as a deadly weapon, but in Guilty Gear X the parasite takes control of Zato-1's body and begins directing their relationship toward its own ends. By the time of Guilty Gear XX, Zato-1 is dead, and the character list refers to the two bodies as Eddie.
Zato-1 is blind, having sacrificed his sight for the privilege of using Eddie. He was a Spaniard and the leader of the Assassins' Guild until being consumed by Eddie; as such he has history with assassins Millia Rage and Venom.
Eddie's physical form is ever-changing: nominally a turbulent cloud at Zato-1's feet, it can become a claw, a set of drills, and other dangerous objects that materialize from unexpected places about Zato-1's body. Eddie often takes a form resembling a gargoyle, allowing it to fly; this could be interpreted as the character's true form.
