Yoshi was a 23rd century Human man. By the 2280s, Yoshi had joined the crew of space station Regula I, as the facility's chef.

When Khan Noonien Singh used the Federation starship USS Reliant to travel to the station and board the facility in the year 2285, the laboratory complement were taken prisoner by Khan's boarding party. Yoshi's was the first throat slit by Khan when the augment superman tried to "convince" the scientists to give up the secrets of the Genesis Device.
