we all know that yamato was created by orochimaru by combining the 1st hokages cells. Many of orochimaru's test subjects went wrong. . what if Orochimaru attempted to combine both the 1st hokages cells with a sharingan. . that would kind of explain why orochimaru was so obsessed with obtaining the sharingan. . *JUST A THEORY TO GET YOUR HEADS THINKING*
Orochi did not created Yamato,he just makes an
experiment of the 1st hokage DNA on Yamato.As a
result,Yamato can use the 1st hokage jutsu,which
is wood element.But,I'm a lil' bit
unclear,from the experiments,only Yamato give a
positive result and the question is why Yamato?..
It was only Yamato because he had similar enough
dna for the two to merge successfully, very
similar to why people have to have similar donors
for organ transplants. If it ain't close
enough, the body rejects it, and you die.
