Rocco Bonnaro

Rocco Bonnaro is a member of Piccaro Calvino's gang. He is involved in organized crime in order to support his blind younger sister, Stella Bonnaro and does everything he can to help her regain her sight. Rocco sees Spike effortlessly take out several hijackers on a spaceliner and begs Spike to teach him how to fight. He befriends Spike although he does not tell him about the bounty on his head. Everything goes awry when Rocco gives Spike a package to hold onto, which contains a plant called "Grey Ash" that he stole from Calvino. This plant, worth millions upon millions of woolongs, is capable of curing "Venus Sickness," the disease which has blinded Stella. Rocco has a rendezvous with Spike and they fight against Calvino's gang.
