Toji was a Bajoran and Counselor aboard the U.S.S. Dropzone, attached to Starbase 55 in the late 24th century.

Sometime before 2406, he and many others were caught in a massive molecular reversion field which caused him to revert to a younger age.

In 2410, he was taken over by a Bluegill spawn mother and falsified a counseling session with Captain Samya before attacking her. He and his fellow companions were then defeated.
