Kymble

From Memory Alpha, the free Star Trek reference.

Kymble was a hologram, based on Harry Kim, that was a character in a holonovel written by the Doctor entitled Photons Be Free.

Kymble was a Trill hypochondriac. He helped Tulak arrest the EMH character and planned to reprogram it. He was very worried that he would damage the EMH's medical program, and there would be no one to help him if he caught an alien virus. He was attacked by Three of Eight in an attempt to help the EMH escape. (VOY: "Author, Author")

Like Harry Kim, Kymble was portrayed by Garrett Wang.
