We’ve learned that villains with smiles are not ones to mess with. Their maniacal laugh and sinister smiles make us want to run very far away. This is all thanks to the Joker. But he’s not the only villain with a creepy smile. Marvel’s Mr. Smile is also a scoundrel who likes his creepy grin to try and lure people into believing he’s a good guy. He’s a demon in a skin suit. His teeth alone will instill terror in anyone who crosses his path. Besides, just look at those long, skinny, sharp teeth! We’re pretty sure everyone who saw this photo will have nightmares for the next week (Comic Vine).
