Dexter Remmick is a recurring character in Star Trek: The Next Generation. He is the anti-villain antagonist of "Coming of Age" and the central antagonist of "Conspiracy".
Dexter Remmick was an officer with the Inspector General's office brought about the Enterprise by Admiral Quinn to investigate Captain Picard for any evidence of corruption. Remmick carried out detailed interviews with the Enterprise command staff, questioning them about errors of judgement or breaches of regulation on Picard's part. When academy applicant Jake Kurland stole a shuttlecraft and nearly crashed it, Remmick was impressed that Picard managed to work out a way to save him but also criticised the lack of security in allowing the theft to take place. Despite this, he informed Quinn that he had found nothing untoward and told Picard he would like to serve on the Enterprise when his current tour concluded.
However, at some point Remmick became the host for the Spawnmother, which infected several Starfleet officers, including a number of senior admirals, with neural parasites. The plan was to take complete control of Starfleet, with Remmick also sending out a message requesting reinforcements. Picard and Riker uncovered the infected officers and killed several of the hosts before following one of the parasites to Remmick, who swallowed it. They promptly turned their phasers on him, killing first Remmick and then the Spawnmother inside him.
