Olsen is a cybernetically-enhanced soldier from Olympus tasked with protecting Iris during their mission in post-apocalyptic New York. Their orders are to locate and disable dangerous wartime weapons abandoned after the global conflict. Initially wary of Deunan and Briareos, Olsen forms a tentative alliance with them upon uncovering evidence that Two Horns' mechanic deliberately sabotaged Briareos' systems to control the duo. Olsen's primary objectives are safeguarding Iris and preventing a prototype superweapon from falling into the hands of the rogue agent Talos. During their journey, Olsen and Iris gradually reveal their Olympus origins and mission to Deunan and Briareos. Talos and his subordinate Nyx capture Olsen and Iris. Talos extracts the superweapon's location directly from Olsen's memories, killing him. Deunan and Briareos recover critical information from Olsen's body, enabling them to pursue Talos and attempt to complete Olsen's mission.
