William / Alpha Omega
Despite there being other Firemen before and after, he had a few extra accessories. Upon his birth from the Advent Calendar in late 2006, he introduced himself as William but that was deemed too boring and he was redubbed Alpha Omega. Another
Fireman appeared the next year, but by the end of 2007 the other apparently died in the climactic battle and William was further just known as 'Fireman'.
In 2008, he was desperately trying to become more than a bit character but apparently took a back seat to
Random Peacock.
Man Eating Chicken told him that he needed a gimmick so people would remember him. He tried becoming 'Mister Marrow' after holding a bone, but that was too close to just holding Chicken to be unique. He held onto the bone for the rest of the season in any case.
