Michael is an Inhuman who lives in Afterlife.
Michael visited Raina about a vision she had about his son. She told him that his son would go through Terrigenesis when he comes of age and be beautiful.
During the War Against the Inhumans where S.H.I.E.L.D. and loyalists of Jiaying battled, all Inhumans who did not fight were evacuated from Afterlife.
As an Inhuman, Michael has the genetic potential to gain superhuman powers after undergoing Terrigenesis.
