During his time on the Bebop, he and Jet are joined by Ein, an intelligent Pembroke Welsh Corgi; Faye Valentine, a gambler and original resident of Earth woken from cryogenic sleep; and Edward "Ed" Wong Hau Pepelu Tivruski IV, an eccentric girl from Earth who is a master hacker. Spike also has run-ins with Vicious on two occasions: in "Ballad of Fallen Angels", while pursuing a Red Dragon executive, Spike and Vicious battle in a derelict church and Spike is nearly killed. Later, in "Jupiter Jazz", Spike hears that Julia was seen on Callisto and abandons the Bebop to look for her. Once there, he stumbles into a drug deal orchestrated by Gren, a man Vicious betrayed who is seeking revenge. During their confrontation, a three-way battle ensues: Vicious escapes, and Gren is fatally injured, but he succeeds in telling Spike that Julia is alive and in hiding.
