his sign is his clans symbol, and he is of the Uchiha clan
Sasuke's name was taken from the famous ninja name 'Sarutobi Sasuke', his clan's name is a variation of 'uchiwa' which is a type of fan (their clan symbol is a picture of an uchiwa fan) their clan name relates to how a fan is used to feed a flame and how the Uchiha clan is famous for their fire jutsu. Sasuke means Ninja warrior but Uchiha means "kill." ^ Uchiha means 'kill'? Really, where did you get this from? (SlytherinSuzee)
There is the nara clan and uzamaki and otsutsuki clan and why is this in animal life?
For power. Orochimaru told Sasuke he could help, and so to avenge his clan and defeat his brother, sasuke turns to orochimaru.
