Juggernaut

Verified Timeline

Lore & Background

Cain Marko is the son of Kurt Marko, who becomes Charles Xavier's stepfather when he marries Sharon Xavier after the death of her husband Brian, for which Kurt is partially responsible. Kurt Marko favors Charles and abuses his own son, Cain. Cain resents Charles and bullies him frequently. Cain Marko and his step-brother Charles serve in the US Army and are stationed in Korea. Marko finds a hidden temple dedicated to the entity Cyttorak. On entering, Marko finds and holds a huge ruby and reads the inscription on the stone aloud: 'Whosoever touches this gem shall be granted the power of the Crimson Bands of Cyttorak! Henceforth, you who read these words, shall become ... forevermore ... a human juggernaut!' The gem channels Cyttorak's power into Marko. The transformation causes a cave-in, and Marko is buried and presumably killed, not being heard from again until a sudden assault on the X-Men's headquarters.

In Their Own Story

Xavier recounts Juggernaut's origin to the X-Men, and after shrugging off the mansion's defenses and brushing aside the X-Men, Marko is seen clearly in the final panel as he confronts Xavier. The X-Men regroup and attack, while Xavier summons Fantastic Four member the Human Torch to aid the mutants; the Torch generates 'pulses' of flame that essentially hypnotize Juggernaut, distracting him long enough for Angel to remove his helmet, making Marko susceptible to a telepathic attack by Xavier. Juggernaut returns seeking revenge and is delayed by three of the X-Men while Cyclops and Marvel Girl, aided by the astral form of mystic Doctor Strange, find and use another jewel of Cyttorak, which banishes Juggernaut to the 'Crimson Cosmos', the home dimension of Cyttorak.
