Then I thought, oh man, thread idea. Anime Character disorders! So go for it. I'll start by doing the One Piece crew.
Luffy - (So many) He definitely has ADHD. He is very hyperactive when it comes to getting all his energy out. He also is ADD and can't seem to pay attention, even in a fight. He has tourettes for he sees no problem in yelling out whatever he thinks no matter how inappropriately timed. He is OCD for Land, meat, and being King of the Pirates. He's possibly dyslexic since he's not the brightest bulb on the tree. And he seems asexual, possibly derived from autism.
Zoro - He hallucinates animals around him. He is too serious, and though that's not a disorder, he also worships demons. He seems traumatized by being beat by a girl earlier in his life which has ever since wounded his pride.
Nami - Klepto. She sees something and decides to have it. Also quite a bit of Wealth envy.
Usopp - Phobic. And a major liar. He also develops multi personality disorder as he believes he is a Soge - King?
Sanji - Perverted. I don't know if that's a disorder, but it's ridiculous. He also has a mermaid fetish. Not good.
Chopper - He's an animal. talking is a good start of his list of animal oddities. He also eats pills to super up. Steroids >_>
Robin - A liar, a bit angsty at times, and majorly deppressed. Introverted too.
Franky - Obsessed with building machines of war. Also has a major ego problem. He wears a mankini....and plays bad guitar to himself. And many, many more. This one needs to be rubber roomed before he does anymore damage to all of us.
Brooke - A skeleton. And a non hip one. Still wearing an afro. His abrupt personality changes and asking to see women's panties is quite awkward as well. He is definitely suffering from being left alone and has left permanent traumitization on him.
^_^ Now you do it! Ace - Pyromaniac cowboy?
*Note: Abby has a fanfic written on the Akatsuki done in this style. I must admit, I remembered this halfway through the thread...So after using this thread I guess go read that. Sorry if this looks copyright infringement like?
