Publication history

The character debuted as an antagonist of the eponymous mutant superhero team in X-Men #12–13 (July & September 1965). In the first of these issues, he rampaged unseen throughout the X-Men's headquarters while the team's leader, Professor X, related the character's origin in a series of flashbacks.

After the canceled X-Men returned in the mid-1970s, Juggernaut returned to fight a new iteration of the team in X-Men #101–103 (October 1975–February 1976). Storylines in Spider-Woman #37–38 (April & June 1981) and The Amazing Spider-Man #229–230 (June–July 1982) explored Juggernaut's relationship with his ally Black Tom Cassidy.

The X-Men and Spider-Man proved to be regular foes for the character, who appeared in The Uncanny X-Men #183 (July 1984), Marvel Team-up #150 (February 1985), and The Uncanny X-Men #194 (June 1985). Juggernaut guest-starred in Secret Wars II #7 (January 1986), battled a new generation of mutants in X-Men #217–218 (April & June 1987), appeared in a flashback story in Marvel Saga #21 (August 1987), and in a humorous episode in Excalibur #3 (December 1988).

In 1995–1996, Juggernaut lead a group of Ultras, who were named The All New Exiles. The All New Exiles met up with the X-Men in a special Malibu/Marvel collaboration, The All New Exiles vs X-Men #0, dated October 1995.

The character appeared in Juggernaut: The Eighth Day #1 (November 1999) and Avengers vol. 3 #23–25 (December 1999–February 2000) with similarly powered avatars and attempted a reformation in The Uncanny X-Men # 410–413 (September–December 2002) and X-Men #162–164 (November 2004–January 2005).

He appeared as a regular character in Thunderbolts beginning with issue #144, and remained on the team until issue #158, during the Fear Itself limited series.

Juggernaut had a solo comic in 2020, by Fabian Nicieza and Ron Garney. Despite being a character from the X-Men franchise, it has plots of its own that do not crossover with the ongoing Dawn of X.

Fictional character biography

1960s

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.
