Hashirama's Artificial Body

Hashirama's "living clone" is a non-sentient clone of Hashirama Senju, created by Madara Uchiha, upon collecting tissue from his former rival.

Creation
At some point after their struggle at the Valley of the End, Madara had collected tissue from his opponent and constructed his organic clone to be used for his plans.

Appearance
It takes the form of an unconscious, naked Hashirama, with six hands suspended inside some stem like object with spike-like appendages, connected to the giant lotus that rests underneath the Demonic Statue of the Outer Path Statue.

Confining the Jinchūriki Arc
Upon Madara leading Kabuto Yakushi on a tour of his secret base, he reveals the suspended clone to Kabuto, noticeably shocking the latter.
