A good character has got to have a distinctive personality, but when do these exaggerated character traits cross that boundary from quirks to psychiatric disorders? It's probably not a shock that fictional characters don't generally behave in a way that would be considered "normal" in the real world, but there are definitely a few of our favourite protagonists out there who are running around with full blown, undiagnosed mental illnesses. For the sake of not-stating-the-bleeding-obvious*, we have excluded the likes of the Joker and the BBC's latest iteration of Sherlock Holmes because, well, duh. These characters are often considered perhaps a little eccentric or a little whacky, but by modern clinical standards, there are one or two of them that could definitely benefit from some professional evaluation and perhaps a little bit of rest and recovery. *In the interest of actually stating-the-bleeding-obvious, this article is for fun and should in no way be used as a tool for diagnosis. Obviously.
