Amaros was a settler on Volan III, a member of the colony's council, and a member of the Maquis. After William Samuels had been captured by the Cardassians, and committed suicide after confessing to being a Maquis, Amaros physically attacked Gul Evek, convinced that his friend had been tortured to death. Amaros was part of the kidnapping party that kidnapped Gul Dukat from Deep Space 9 and among those who was interrogating him. Amaros was captured by Commander Benjamin Sisko's rescue group only to be released so he could relay a message to Cal Hudson, letting him know that Starfleet knew nothing of his betrayal and could return to Starfleet.

Amaros later served as Hudson's co-pilot in a Maquis raider when Hudson attempted to destroy a Cardassian weapons depot. Deep Space 9 personnel however, engaged Hudson's ships, disabling their weapons, and forcing them to retreat. (DS9: "The Maquis, Part I", "The Maquis, Part II")
