As we all know Shaq killed the movie Steel by suckin so bad but does anyone know what happened to the comic book version.
Addendum to the previous answer - although he doesn't have his own comic currently, John Henry Irons still appears in comics, most recently in several issues of 52.
Was cancelled after the 25th issue or so....the movie probably killed the comic too!
The comic book has been long cancelled. You can see Steel in the ongoing 52 miniseries.
Steel's own series was cancelled around issue #50, after which he went on to a co-starring role in Superman: The Man of Steel. Steel was eventually injured in a battle with Darkseid, at which time his niece Natasha took on the role of Steel. John Henry recently resurfaced in his heroic identity in 52, where he's been injected with Lex Luthor's metagene, making his body living stainless steel.
