 It also begins a plot thread in which Brock is informed that there are other symbiotic hosts like himself.A four-part series published between December 1994 and March 1995, the story covers the return of Venom's offspring (Scream, Lasher, Phage, Riot, and Agony), who are seeking aid to control their symbiotes, and the murder of Lasher, Phage, Riot and Agony's hosts by Scream (who has become insane).The storyline also raised the question of whether Brock or the Venom symbiote was in control, leading into the five-part crossover story "Planet of the Symbiotes" in 1995.
