In his Post-Infinite Crisis Kryptonian iteration, Dev-Em is never allowed to experience the full measure of his abilities as he is never permitted full exposure and absorption of the yellow solar radiation of Earth's sun before he is eventually defeated and banished back to the Phantom Zone. Like other Phantom Zone escapees, Dev-Em's abilities are insufficient compared to those of Superman due to his relatively short time in the Sun compared to Superman. His only advantage being his superior hand-to-hand combat prowess as a member of Krypton's military as well as his ruthless mindset and courage in battle.
