Juggernaut

How Juggernaut joined the Tourney
Cain Marko was the son of Dr. Kurt Marko, who was an atomic researcher. Cain's parents separated and Cain was eventually sent to a boarding school. Kurt Marko's colleague, Dr. Brian Xavier, another atomic researcher, died in an accident, and Kurt Marko eventually married Xavier's widow Sharon for her great wealth. On marrying Sharon, Kurt Marko moved into her large Westchester County mansion, where he lived with her and her young son Charles. Cain, who had become a cruel and spiteful boy, came to live at the mansion as well. Marko, eventually dug himself free with his newfound power and made his way to America to use his power to kill Xavier. He was defeated by Xavier and his original team of X-Men with the help of the Human Torch. Over the years the Juggernaut has clashed with Xavier and both the original and new teams of X-Men repeatedly. He has also formed a successful criminal partnership with his old friend Black Tom Cassidy.
