In The Series Edit
Eddy was first met in South Carolina during a resistance mission into a nearby suspicious warehouse. He was working for the Arume, creating autonomous machines for them. The two soldiers who ventured there almost managed to capture him, but he escaped in an Arume airship
Eddy was later met in a research base at an unknown location, he appeared to be working on genetic modifications with the Arume.
Eddy has a very maniacal personality, he ends up stuttering in his speech and he's usually on edge. The Arume probably abuse his crazed personality to manipulate him and use him for his knowledge of robotics and genetics.
