Black Blooded Psycho

When the gods got bored and decided to set up a wager,they didn't realise it would drag on to the point where no one remembers how long the wager has been going on for! Finally it was decided to have a tournament of sorts they would take one person from a race they create and have them fight in said tournament. Something they didn't know was that they'd be so exhausted after making planets and life,and would fall asleep for 4.54 billion years? its not their fault Is it? Well anyways eventually one very. Interesting? to say the least god chooses a murderer to fight for him everyone has to wonder why...
