Socom

An artillery type Peacemaker, like Cz. He appears later in the series. His personality is like Steyr's, but not as sadistic. He is also not as overly determined to get chances to kill people ( In an episode, while waiting for Pacifica to reach Leinwan, Steyr suggested to start killing people, but Socom, coming in the middle of the conversation between Steyr and Cz on who seems more human, said that there was no need to play petty tricks.). Nevertheless, he hates humans, or at least feels no particular desire to protect them. He is Steyr's partner. Destroyed in the last episode by the three Gigas when they use their light lances to slice him into three sections. (Source: Wikipedia)
