OSH-4 is a mechanical droid with the recycled memory core of an old Imperial Safety Inspection droid who belonged to a Sluissi starship mechanic named Szass Xorem on Imperial-Occupied Sluis Van. After tinkering with the droid's memory core with the hopes of taming OSH-4's more eccentric personality quirks, Szass discovered hidden Star Destroyer blueprints that revealed strategic weaknesses in their designs. Being a sympathizer, Szass contacted the rebel alliance to coordinate a hand-off OSH-4 for a debriefing. Fortunately, since the droid's memory core was refurbished, the Imperials do not know that this information is on the loose, as they would quickly seek out and terminate anyone in contact with the droid. Unfortunately, the communication was intercepted by Teemo the Hutt and a team of bounty hunters disguised themselves as Rebels and took OSH-4 from Sluis Van. Szass Xorem was killed during the extraction. Before reaching their rendezvous with Teemo, the group discovered what the information was and how much it could be worth to them.

After being cared for by Szass Xorem, OSH-4 feels compelled by loyalty to it's dead master to complete the mission to bring the intelligence to the Rebels.

Responsibility (5)- must finish mission that Szass Xorem died for.

Bounty (5)- target of bounty for Teemo the Hut

The droid's lingering code enables it to identify and repair unsafe conditions making it excel as a mechanical droid. Unfortunately, recycling the memory core developed a strange bug and the droid has become a little paranoid. This paranoia, combined with programming that requires it to report any safety violations immediately has given OSH-4 a bit of a frantic personality; constantly seeing problems and loudly proclaiming them to it's colleagues.
