even if it wasnt shown it doesnt mean he cant....for all we know the sun seal`s primary purpose was a collaborative chibaku tensei(with sasuke`s moon seal)
maybe he can as his power with the rinnegan has evolved by now
and the arrow was imbued with bijuu`s chakra and the whole lightning avatar inside PS too...he used their chakra and transformed it into lightning itself
my impression was that KM is just naruto using kurama`s chakra to do stuff and BM is when naruto becomes one with kurama(can go into a bijuu avatar mode)
i think big bijuudamas from both gyuuki and kurama can destroy it..but i am only implying this because naruto and bee were going to destroy gedo mazo at some point but it transformed into a juubi before they could
1-i think he used preta path to absorb the chakra and cover it in a susanoo armour...i could be wrong about the preta path thing...however he did take the chakra
2.i think if he could,he would...this seems way too OP
3.yeah i saw the face
it is shown that he is under IT(because of the rinnegan eye)
however..
he is clearly able to move on his own even though we saw that everyone else under the effect of IT was paralyzed and unable to move....
maybe he still has sth up his sleeve..idk
what`s your reasoning for him not being...
considering he felt confident enough to take on both naruto and sasuke he must have been insanely strong......SO6P minus one half of kurama..that strong
It can be some teleportation jutsu...even more advanced than kamui....could be some form of more advanced izanagi...deva path ability...who knows....teleportation sounds nice :-D
