John was born in Australia to a pair of former criminals on the run. After settling down under new identities, they attempted to raise John right. They were very unsuccessful as John was a chaotic child who loved violence and setting things on fire. He first when to Juvenile Detention when he was eight, and it pretty much became his summer home.
When he was sixteen, he was lighting a pile of garbage on fire, and he discovered he could control the fire, the way it moved, the way it took a form. He discovered this could be his gold mine. John ran away from home and began setting anything he could on fire, earning himself the name Pyro.
When he turned seventeen, John snuck his way onto a plane to America. He quickly spread his reputation after he lit the Golden Gate Bridge on fire and the Avengers had to save it. When Pyro discovered the mutant criminal organization called HYDRA, he knew he had found where he belongs, and he even planned on becoming the leader.
Pyro joined HYDRA and quickly befriended Baron Magnus's son, Quicksilver. The two of them enjoyed torturing the human agents and anyone beneath them. However, Baron Magnus thought Pyro was too reckless and attempted to hurt him. However, Quicksilver stood up for his friend and defied his father. This made Pyro rethink wanting to kill Baron Magnus, but he still craved leadership.
