In his early years, equiped with quantum entangled neuro links, Catnavido explored the realms of mankind for forgotten lore and legend. He was a fury in battle and a skilled medic. Tyrell Corporations tapped his neuro readouts and made a few replicants of him but the project was abandoned in 2019 with the dead of Eldon Tyrell.
At home, Catnavido joined the police till turfed out on some questionable orders. In 2029, at Sarif Industries, he got augmented after a near-dead incident. In 2100, at Task Force 29, under new mission statements, he was assigned to Mars to aid government surveyors for surface reconnaissance.
Catnavido joined the Normandy in 2183 but lost his life in its explosion.Eliza Cassan, a silent witness in life, picked up on his seized neuro transmissions and reactivated his old Tyrell replicant. Hence Catnavido was brought alive more human than human.
