Some fictional characters are so original that one can't help but wonder how a human mind was able to think of them. That wondering often isn't baseless as in many cases writers simply base the characters they pen on people they've met, seen or heard of in real life.
Here are some such fictional creations that actually owe all or most of their traits to real people.
Shrek and The French Angel
Though the DreamWorks writers have never admitted it, it's fairly obvious to see where they found the inspiration for Shrek's physical appearance.
Avon Barksdale and Nathan Barksdale
