The Incredible Luigi

Luigi is a drunk, especially when exposed to radiation (Via)

Luigi has never had a chance in video games. The only time he's ever shown his bravery and heroism was when he had a vacuum on his back or had to solve maths to save his far more famous brother. This made him mad. You wouldn't like Luigi when he is mad.

I'm a huge fan of the artist, Dan Hipp. If you like this art you can purchase it at his site, supplied above. It's worth every Hulk-ed out penny.
