Vanja Mrgan has imagined what different famous characters would look like with beards. From Robocop to He-Man Batman to Wario to Popeye to Porky Pig to Boba Fett to Snoo -- Reddit's alien mascot -- they all look quite cool. Some even better than the real thing (like Popeye, Wario, and even Batman!)
Vanja Mrgan is a brilliant Croatian illustrator based in Clearwater, Florida. He also collaborated in doing illustrations for the famous game The Incident, created by his brother Neven Mrgan and Matt Comi.
