Conrad Roth is the 52-year-old English Captain of the Endurance, the ship on which Lara travels when it is struck by a storm and splits the ship in two. In addition to piloting ships, he is also a salvage and part-time treasure hunter and enjoys rock climbing, hiking and wreck diving. In Tomb Raider (2013), he acts as a mentor figure for Lara through the course of the game.

As an ex-military person, Roth served two combat tours with the Royal Marine Commandos (RMC). After leaving the military, he put his specialized skills to use as wreck-diver and part-time treasure-hunter round the world. Roth earned a reputation for toughness, competence, and a willingness to bend the rules restricting traffic in historical artifacts. Those qualities make him highly sought-after among discerning private collectors, such as Lara's parents. For several years, Roth accompanied Richard Croft on over a dozen treasure-hunting expeditions, acting as a guide and, when necessary, bodyguard.

Roth got to know Lara while working with her parents. After her parents' disappearance, he took on her guardianship, teaching her practical skills such as rock climbing, navigation, and other survival skills. With her parents gone, Roth is the closest thing Lara has to a family, and he takes that role seriously.

Roth considers himself married to the sea. He dreams of finding that one big prize that will allow him to retire onto a large yacht and live out his days sailing wherever the winds will take him. If Lara is right about Yamatai and its significance, it might as well be his last job.
