Raiden's doctor

A doctor treated the injuries of the Maverick cyborg Raiden, and replaced his eye, following his fight with Desperado member Samuel Rodrigues in 2018. During this time, he also replaced some of Raiden's memory cores that had been damaged in the duel. He held some authority during the emergency treatment, giving orders to other doctors.

Behind the scenes
The doctor first appeared in the "Arm" trailer for Metal Gear Rising: Revengeance. Prior to its release, the doctor was first mentioned in a leaked casting call for at least four actors to portray characters for a then-upcoming live action trailer for Rising. The recommended traits for the live actor portraying the doctor were that he was Caucasian, within his 50s, possessed strong eyes, scars, and even wrinkles if necessary.
