The coolest guy on the whole fucking universe. He is so awesome that Chuck Norris makes Gassan jokes. His swag levels are over 9000! He's pretty much a big deal where ever you go, even if its not on Earth. He has some haters, but they have nothing on him. He makes the Hulk look like a fucking pussy.
Man that guy is so awesome. His name must be Gassan!
