<p>Double Mangekyo Kakashi has plenty enough power and chakra to warp away the Ten-Tails or the Top Buddha. He has Obitos Chakra plus his own, plus Obito's Six Paths Power/Chakra. He also made it a point to point out how very powerful his eyes became with that gift. Same way Dan gave his chakra to Tsunade, same way Hagoromo split his chakra between Sasuke and Naruto.. (they may have awakened the Rinnegan and the SPSM, but they no longer have Hagoromo's chakra therefor they are indeed weaker than their final fight with Kaguya and against each other at the VotE, Naruto gained a Hashi arm and the full Kurama to somewhat mediate that, while Sasuke gained Mastery over his Rinnegan, now able to turn it off at will) Kakashi was not an Uchiha, or had the Sharingan KKG and was not an implant user when Obito gave him all of his chakra so he did not keep the awakened Double MS.
