Tesla: God of Thunder
The genius inventor Nikola Tesla mashed up with Thor seems so brilliantly obvious that I'm not sure why I hadn't seen it before. Inspired by the Tesla coil and Thor's ability to wield lightning, artist Luiza "Zee" Mendoza created this mashup for Cracked. This art is available as a t-shirt, iPhone case, mug, pillow, tank top, and art print.
