Undiagnosed Mental Illnesses in Fictional Characters

So apart from the obvious Anakin Skywalker with BPD (Borderline Personality Disorder), there are quite a few other famous characters with undiagnosed mental illnesses.

I came upon this link:

I think the most surprising of all was to see that (the infamous) "they" diagnosed Glinda the Good Witch, from The Wizard of Oz, with Sadistic Personality Disorder. Their reasons, however, were quite legit.
