this looks really interesting - 
it reminds me of a theory my room-mate and I 
came up with a while ago.
Basically stated - the seven deadly sins of Ranma 1/2
Ranma - Pride
Happosai - Lust
Genma - Gluttony
Nabiki - Greed
Soun - Sloth
Akane - Anger
P-chan - Envy 

So basically every one in the Tendo Dojo 
is an incarnation of one of the 7 sins
Except for Kasumi (she's Satan :))
