If there was a yearbook for the Marvel Comics universe, Juggernaut would easily snag the superlative for "Most Improved." The one-time X-Men villain has had one of the slowest burn bad-guy to good-guy arcs in comic book history, and this past week's Amazing Spider-Man #68.DEATHS clinched the deal: nothing can stop the Juggernaut from self-improvement.
Introduced in 1965's X-Men #12 by Stan Lee and Jack Kirby, for decades Juggernaut stories had a repetitiveness to them. Juggernaut would attack the X-Men, they would somehow get his helmet off and then knock him out. Rinse, repeat. His whole deal was running through things non-stop, and that was pretty much it. But in the 50 years since the character was introduced, we've slowly learned more about him as he's gone from villain to anti-hero, to definitive hero.
