Kevin Keeler was a 23rd century human who served in the United Federation of Planets Starfleet. As a young man, Keeler attended Starfleet Academy, and graduated 87th in his class on Stardate 3342.8. He eventually rose to the rank of Lieutenant, and as such was given command of the Ptolemy-class tug USS Masada. During his tenure as Captain of the Masada, his ship was captured by a band of Elasi pirates led by Cereth ajElasi. Keeler and the Masada crew were rescued by the USS Enterprise, and the Elasi were taken into custody. (TOS video game: 25th Anniversary)
