Keene

From Memory Alpha, the free Star Trek reference.

Keene was captain of the ECS Fortunate in the mid-22nd century. In August of 2151 Keene was injured during a Nausicaan attack, during which time, his first officer Matthew Ryan took command and attempted a retaliatory strike against the Nausicaans. When Keene recovered, he demoted Ryan for his reckless actions. (ENT: "Fortunate Son")

Keene was played by Charles Lucia.
