Parahumans were superpowered humans who gained their powers in a way unrelated to the metagene. Many parahumans had powers related to the paranormal or magical properties. As a result, they were quite often immortal and gained their powers prior to the implanting of the metagene. Parahumans like Shazam, who were often incorrectly labelled metahuman, were susceptable to diseases like the Amazo Virus. Shazam and Black Adam were only truly called Parahuman due to the source of their powers, a magic that existed long before the metagene.
