Peter was the brother of Marlene Alraune and a doctor of unknown specialization. When testing a drug on one of his patients, it didn't go as expected and he was turned into a monster. The patient, now going by the name Morpheus and having mental powers, attacked and severely wounded Peter, but he survived, nonetheless.
Sometime later, Morpheus reappeared and went after Moon Knight and Alraune. After being shot by his mentally controled sister, Peter ended giving his life to cancel out Morpheus' powers.
