They're hella strong and this makes me think whether the Hatakes are a completely unique kind. I can say the same for the Harunos

Yes, the Harunos are known for their kekkei genkai Useless no Jutsu. Activated upon birth, a Haruno will become useless in nearly every situation until they attain enough power through training with a powerful figure for several years during late adolescence. Side effects include being a vain and egoistical idiot until the required amount of power is gained.
