He is the son of Janus Outrigger and a brother to Ramos and Rikter Outrigger. He is encountered working on the Outrigger family's Dune Busters within their settlement. Later, when Nicholas Raine and Durar Hagar are attempting to repair a Dune Buster in Ray's Oasis, Hagar sends Raine to retrieve buggy parts from Johan. Unfortunately, Johan has been robbed of many of his spare parts by members of the Wasted Clan and in turn sends Raine to raid the Wasted Garage and steal the parts back.
Shortly after these events, the Outriggers decide to abandon the settlement due to rising bandit activity. They are not seen or heard from again, though Nicholas encounters Rourke later in Subway Town.
