Ken Kato was the chief engineer aboard the Starfleet hospital ship USS Cole from 2385. (Henglaar, M.D.: "Risk Factors")

Durable captain Dana Russell once described Kato as, "some skinny adolescent with social issues who told me to take a hike" who "looks like he belongs in high school." (Henglaar, M.D.: "Profit Without Honor")
