Actually, Deucalion was a true alpha. When he killed Marco, it did more than just enhance his abilities, it turned him into a demon Wolf (because he is a true alpha and true alphas are powerful enough without killing). Proof of this is when Scott almost kills the hired swat guy and his face turns more and more alike to Deucalions. He doesn’t become a demon wolf because the contracts were canceled.
