Calvin Zabo, originally Calvin L. Johnson, is the father of Skye, and the widower of Jiaying, a surgeon to the underworld, among his other skills and trades. He was first seen (from the back) at the end of "Beginning of the End". He had an unparalleled knowledge of the Diviner, having been the one to inform Daniel Whitehall that this was its original name. In "What They Become" he is revealed to be Mister Hyde, hence his anger issues and superhuman capacities. Zabo's relationship with Jiaying led him to the edges of the Inhuman community.
