The Man of Steel's imperviousness to harm is limited, as he is susceptible to Kryptonite, a radioactive substance from his destroyed home planet. Magic and psionic attacks can also weaken him, but his primary vulnerability is his reliance on yellow solar radiation. If deprived of it, he is no longer invincible and becomes mortal. This 7" action figure from McFarlane Toys depicts Superman in incredible detail and features ultra articulation with 22 points of movement for a wide range of posing options. The set also includes a bald eagle, display base, and a collectible art card with character art and biography.
