10 DC Characters Weaker Than Superman Who Could (In Theory) Kill Him

5. Johnny Sorrow

Johnny Sorrow (who is an awesome character, incidentally) has a very simple way of killing Superman - if Superman looks at his exposed face, he'd die. Sorrow is by no means a low-powered character in general - he's a high-end energy manipulator who, by default, is actually completely intangible in his base form (and therefore pretty much invulnerable to all physical attacks).

Having previously been a silent film actor, an accident with a teleportation device shredded his body and transported his remains to another dimension. An entity called the King of Tears restored Sorrow's consciousness, which now inhabits a floating suit and mask. When he takes off the mask to expose his face, he becomes tangible, but anyone looking upon his gaze and whom sees his grotesque features will almost certainly die. Indeed, it is so grotesque that it has even effected blind characters and indeed Johnny himself (when he saw a recorded image of himself he was paralysed).

Given that his face has caused magical beings as powerful as the wizard Shazam to turn to stone, there is no justifiable reason why it wouldn't kill Superman outright (despite the fact that Superman has a far bigger array of superpowers than Johnny, who has no other enhanced attributes).
