The Uchiha Arsenal.
There are many things that only the Uchiha have, thing that only the Uchiha can do, such as the Uchiha smirk, designed to strike fear, trepidation and uncertainty into the enemy.
The Uchiha 'hn', used to keep all unwanted conversations at bay whilst appearing aloof and untouchable.
The Uchiha aura, which has the effect of making every soul within a 30 metre vicinity feel unworthy and incapable of any sort of accomplishment.
The Uchiha looks which have the ability to turn even the most heterosexual person into a homosexual and the most faithful partner into a cheating asshole.
The Uchiha form in general, able to perform unthinkable feats of flexibility, agility, power, prowess and stealth.
Then there's the Uchiha mind, brimming with knowledge and strategies. Perfect, indestructible.
And let's not even get started on the eyes.
