All 8 Of Batman's Mental Illnesses
7 Of 8 Munchhausen- By-Proxy
This disorder, which usually exhibits itself in terms of a parent causing the illness of a child in order to garner attention, sympathy, and means of support for themselves, is something close to what Batman does with his many companions. Namely, he puts them in constant danger so that, perhaps, he can save them as his parents failed to save him from the life he's inherited.
8 Of 8 Coulrophobia
A guy who has to fight a deranged clown all the time can understandably acquire a fear of clowns, kinda a no-brainer. To fight this fear, Batman keeps a giant Joker card bearing a big clowny grin on it right there in the Batcave.
