.....how long does it last,is it temporary,does it last until naruto reverts back to normal,do they get to keep it and if naruto awoke a perfected bijuu mode would the kyubi cloaks the alliance has change aswell.
when he gave kakashi chakra and kakashi warped the hachibi he was exhausted afterwards so i guess he used it all up
but kakashi didn't have a chakra cloak so im not sure
it is a fixed amount. Same as when Kyuubi gave Naruto clone chakra to fight Madara when he first appeared (before the three other kages came). Naruto used it all up to destroy the forest that Madara created.
I suppose that if Kurama keeps recharging himself, Naruto can keep passing it on. Kind of like a solar charger...
I think it will wear of when naruto reverts back to his original state and/or when the chakra generally wears out. maybe even when everyone disconnects any physical contact.
Well none of that has really been revealed yet but I would assume it wears off once they use the chakra. Essentially what he did is give them a bunch of chakra to use, once they use it the cloak will be gone.
