Dr. Vryolak discovered a labyrinth in Aegean with a secret formula that was able to combine the strength of an animal with the mind of a man. He would later use this concoction on his own son who was losing a battle with a disease that would soon take his life. Having already lost his wife he would not let his son die as well. Upon giving Miklos the treatment he began to grow stronger eventually changing into a fabled Minotaur of legend.
When Whitney Frost washed up on shore Dr. Vryolak decided to nurse her back to health and mislead her into thinking he could fix her face. In actuality he wanted to create another beast using the chemistry he used on his son to create a mate for him. Thankfully with the combined efforts of Iron Man, Jasper Sitwell and even Miklos himself that didn’t happen. Miklos sacrificed himself to save the others while he and his father stayed in a cavern as the entire island collapsed on top of them seemingly killing them both.
