Chimera Technique

The Chimera Technique is a forbidden technique that was developed by Hiruko, a missing-nin of Konohagakure, in order to compensate for his lack of natural special abilities. Hiruko uses the technique to integrate the bodies of others with his own, allowing him to obtain any Kekkei Genkai they possess, as well as other special physical traits. The technique is also used by Hiruko and his followers to create formidable creatures which bear the traits of multiple animals.

Influences
A chimera is a mythological creature composed of the parts of multiple animals, and is also a genetic term for hybrid animals with more than one DNA pattern. This is likely a reference to the fact that Hiruko developed the technique as a way to adopt the genetically inherited abilities of other shinobi, regardless of his own bloodline.
