Paul Domenic was an engineer with a passion for architecture. During an environmental survey he acquired the ability to build any structure he could think of. He became the Master Builder. This new power came at a price however, he soon found out he could no longer imagine new structures. He could only rebuild the structures he had previously built before becoming Master Builder. He was a member of the now defunct Berzerkers.
