Kevin Sinfield

Kevin Sinfield (a.k.a. The Leeds Rhino)

Kevin Sinfield was a mild-mannered rugby league player and nucleobiologist who, after injecting himself with genetically-enhanced rhinoceros DNA, developed superhuman abilities. He is now known as the Leeds Rhino.
Sinfield used his connections in the inner circles of rugby league to find Britain's most promising athletes, and after gaining their trust, formed the Super League. They watch over the North and maintain a strong relationship with the George Boys, the American peacekeeping superpower. Following Kim Jong Il's siege of Merseyside and the United Kingdom's subsequent relinquishing of the county as a part of its dominion, his focus fell onto freeing the people of Merseyside.
Sinfield's weakness is that he succumbs to violent murderous bloodlust as a result of his primal DNA. The rumours which circulate about his devouring the owners of Knowsley Safari Park during their journey across the Pennines are true.
