Why is Jura so strong?
Could it be that Jura is so strong because the Ten-Tails absorbed Sasuke? Sasuke, the descendant of Indra, has a strong connection to the Otsutsuki line and is essentially half Otsutsuki, and Sasuke also received cells from Kabuto Hashirama. Would this lineage and the connection to the Otsutsuki's immense powers contribute to Jura's similar superhuman powers?
Jura is strong because the author wants that. He’s not based on Sasuke, he’s the only one who has no host. He is almost the ten-simplified himself, or his incarnation. It has absolutely nothing to do with Sasuke. The strength of Jura or generally of each Shinju clone comes therefore that they are modified parts of the jubi, modified with a shinjutsu (code’s claw tracks) that originally comes from Shibai Otsutsuki, so his cells are in play.
Hidari is the one based on Sasuke.
But apart from that there is no connection between Jura and Sasuke, Sasuke is by the way not “sozusagen half Otsutsuki”. Indra was only one quarter of Otsutsuki and Sasuke is just his rebirth.
What are you talking about?
The ten-minded was split by code and transformed into human creatures. These beings have the ability to absorb people, which gives them a special form. When a ten-simplified person absorbs the chakra of an Otsutsuki, he gets immense powers. Since Sasuke is a descendant of an Otsutsuki, this could explain why he has such extraordinary strength.
