genjutsu vs Sasori/tsukuyomi vs Hiddan

[Rollin90Shikamaru]

:D Genjutsu is extending your chackra(usually through sight or sound) and mess up the chackra flow through your opponents head causing mental damage and disorientation. It can be canceled by having another person disrupting your chackra flow. Some genjutsu are the result of the effect of a dojutsu like tsukuyomi. These don't require hand seals.

Is Sasori affected by genjusu ? If he is , how is he affected and why ?
Hiddan is a masochist and he has been stabbed, burned, chopped to pieces and decapitated. How will tsukuyomi affect him? :D

i dont think genjutsu is a factor against sasori imo

hidan will still be affected by tsukiyomi because it attacks you with your worst nightmares i reckon

I thought the same thing but now i'm not sure. Sasori still has a conscious mind inside of that...thing.
True but what are Hiddan's worst nightmares ? Fluffy panda bears, friendship and Sakura on a bad day ?
