Stark initially came into contact with John Crichton while both were being held prisoner in Scorpius' first Gammak Base devoted primarily to wormhole research. Having been a prisoner for many years, Stark informs Crichton that his (Stark's) survival is due both to his resistance to the effects of the Aurora chair and his pretense of acting mentally unbalanced in front of the guards, which causes them to leave him alone more often. Stark assists Crichton in his escape to Moya and quickly forms a bond with Zhaan. During one of the crew's misadventures, they are put on trial for murder and Stark is executed by "dispersion" or the scattering of his molecules into atoms. He survives this because he is mostly made of energy, but his appearances thereafter show him as being more uneven in his personality.
