Kyren Ground Captain

The Ground Captain was a male Kyren, part of Noble Commander Crydax's Earth invasion force. He took an active role in the invasion, taking the Doctor and requesting permission to use the Fragmenter. The Ground Captain led the Doctor, Korina Emily Whitaker, and human Harry MacReid, from the Albion Hospital, but lost them to Constable Doyle.

The Ground Captain was presumably killed with the rest of the invasion fleet when the Fragmenter was activated by the Doctor, eradicating them.
