The name of an all powerful sword in soul eater that according to legend is very powerful but in reality he is just a pain in the ass that looks like a peguin that has a top hat and a cane that got its face smashed. He also loves to say FOOL! and is the best charicter ever.
Me: now presenting the pain in the ass excalibur!
Excalibur : FOOL!
me: ( trying not to throw him off of a mountain)
