Iviok

Captain Iviok was the commanding officer of the Federation starship USS Jenova in the late 24th and early 25th century. 

History
Sometime, in the 24th century, Rivera Gotens headed a project that required a probe to be launched, aboard the Jenova. After launching, Rivera Gotens got in to a trivial argument with Iviok about the aesthetics of the probe.

In 2375, Iviok's ship took part in a small fleet to protect the Flortarious sector. During a hostage situation, in which the Captain's of the fleet were contained, Ensign Dan was intimidated by him. He later took the Jenova into battle against a Jem'Hadar attack. ("The Bajoran Trove")

Personality
Iviok was known to lack a sense of humor, or, at least, he kept it to himself. His trademark response to many interactions were a distinguising, singular "grunt". ("The Bajoran Trove", "Experimentalism")
