Iron Man Officially Has His Own Version of Kryptonite (& Tony Stark Invented It)

Warning: Spoilers ahead for I Am Iron Man #5!The supposedly indestructible Iron Man secretly has his own Kryptonite that was created by none other than Tony Stark. The Invincible Iron Man’s solid suit protects him from any serious blows that would otherwise destroy his exposed mortal body. He has come across some near-death moments in the past when supervillains like Doctor Octopus and Doctor Doom actually found ways to defeat him. However, the most surprising adversary Iron Man could ever face with a way to ultimately destroy him…is himself.
