Warning: Spoilers for The Avengers #19!Tony Stark’s original addiction doesn’t even top Iron Man’s alcohol addiction. Tony Stark’s penchant for liquor has been well-documented, most infamously in “Demon in a Bottle” by David Michelinie, Bob Layton, and John Romita Jr., one of the best Iron Man stories of all time. However, Marvel has made it a point to remind readers in recent years that Iron Man’s first addiction wasn’t alcohol.
