In 2366, Esoqq was abducted and replaced with a replica by a hitherto unknown species along with Jean-Luc Picard and the Mizarian Kova Tholl in a covert experiment to study their different attitudes towards authority, which included the impostor Bolian Mitena Haro. Esoqq's attitude, typical of his people, was that authority was not needed. Food given to Esoqq while imprisoned was poison for him, designed to agitate the others. He was the first to cast suspicion that one of the others was an impostor, mostly focused on Tholl, as he saw him as a collaborator. He helped open the door and was punished alongside the others.
