Kekkei genkai (Earth-1529)

A kekkei genkai is an anomaly in the human DNA that allows a bender other elements and use unique techniques that no one else can learn. Kekkei genkai describes both the anomaly and the resulting technique. Most kekkei genkai are passed down between a clan's generation, although sometimes that is not the case. Commonly, a bender will only inherit one kekkei genkai, but some individuals are known to be born with two of them.
