Are you reminded of the Saiyans from Dragonballz when you look at the Uchiha Clan?
The reason I ask this is because it kind of occured to me that the Saiyans and the Uchiha clan had many similarities. For one, they look kinda similar to each other in hair and facial features. They each had special abilities compared to the others in their respective universes. Take for example, the saiyans had the natural ability to use energy blasts, or their stronger after every battle genetic, and of course the Uchiha clan has the Sharingan and its more advanced levels. They are both battle loving people (minus Itachi and Gohan). It's stated by the oldest in each the Saiyans (Vegeta) and the Uchihas (Madara) that they both had a fondness for battle.
I was just wondering on your guy's thoughts about this. They seem fairly similar to me.
