Amal Kotay

Amal Kotay, also identified as Employee 9363, was an identity assumed by Commander Chakotay, as he attempted to infiltrate the homeworld in 2377 in order to save  Janeway and her crew from the planet. This fictional name came with a surgically altered face that changed Chakotay's appearance. He had a level three-qualification in microkinetics and a level five-qualification in thermionic conversion.

This new identity was necessary because Chakotay had already identified himself by his real name and appearance to several Quarren officials.
