These clones are after Sarada, Konohamaru and many others. Since Hidari is the only one we seen fight we will talk about him first. Hidari is one of the Shinju Clones of the 10 Tails that Evolved because of Isshiki’s chakra that was in codes karma. This 10 Tails is a different species from the one we seen from the 4th war so it will have some powers we never seen before. Hidari has Sasuke’s chakra, the rinnegan, 10 tails powers which is pure nature energy and code’s claw marks. He’s so fast Boruto and code were barely able to react despite being very fast. He can also use chidori and presumably more jutsu Sasuke had. These evolved versions seem to be around base Boruto level in power. And Konoha has to fight against 4 of them. I wonder how the story will unfold.
