108 "Decline and Fall"
Maximus, now demoted to Crewman, is sent on a mission to his home planet (8-92-4, from the TOS episode "Bread and Circuses"), accompanied by Stadi, Veltr'a, Petersen, and M'Kress (who spends the episode out of sight on sensors). The Starfleet Anthropological Survey of 8-92-4, based at the U.S.S. Cuchulain, has discovered
cultural contamination and
a suspected Romulan cloaking device at a site on the planet's south pole.
Lt. Cmdr. Strep, Betazed Commander of the survey, lead Maximus, Stadi, Veltr'a, and Petersen on an investigation of the site. A firefight with
a group from the Romulan-armed century guarding the area ensues. Maximus surrenders, but then (rather
foolishly) changes his mind and tries to run for cover, and is disintegrated
at point blank range. The away team win the initial skirmish, but then the
cloaking field expands to include them and the full century attack. The team
barely escape, with a local prisoner.
