Rincewind - Wizzard in Discworld

He is a polite yet cowardly wizard with (almost) no magical ability and whose ambition in life is simply to continue having a life. He never passed an exam at Unseen University. The highest score he received was 2% for spelling his name right. He has been on many adventures, but almost entirely by accident. He seems to be constantly running away from danger (as such, most of his scars are on his back). He is the first to call himself a coward, although he's frequently frustrated by circumstances which cause him to be accidentally heroic. He always gets himself into dangerous situations, because he always has to help the helpless and innocent, even if half the time he would rather run away before it starts to happen to him. Also he is very realistic and rather cynical, so he knows when a situation is wrong.
