Him knowing it's a clone doesn't matter for obvious reasons. It's not meant to fool him it's meant to act as a shield, Hashirama can't target Avatar 1 if Avatar 2 is in front of it regardless of them being unable to move.
Except he can since clone 1 being in front of original won't let the original evade it because Chojo will be landing from up above and has the AOE to effect both of them, this doesn't even make sense because a single clone avatar isn't big enough to block the original or to encompass the entire vicinity of Chojo, which would be the only way to ensure that the original gets hit
Not to mention that if naruto even manages this through a clone avatar or attempts it, then minato would just teleport it away once it's bound
You aren't making sense here. What does Naruto's Avatar have to do with anything I said? Naruto's Avatar doesn't throw BDFRS, Naruto throws it and Naruto doesn't need to be outside of his Avatar to use BDFRS nor does his Avatar need to be free from Myojinmon because it being bound doesn't mean Naruto is immobile inside of it. So you can forget about Shinra Tensei and S/T Barrier being used. You can also forget about any of Madara's attacks reaching Naruto from inside his Avatar.
This doesn't make sense and was addressed above regardless.
Nope. It was both.
If naruto is attacking by himself when he's within his avatar then yes, ST and The barrier would counter it and send it back to him. Naruto attacking through himself won't change the fact that the second, the BDRS come in their way, the barrier and ST will form and send them away.
Sending the BDRS accomplishes nothing because all it'll do is come right back at naruto. And he sure as hell gets in trouble Since his defense is bound
If he sends in 9 BDRS like you say he would then:
>S/T barrier and ST send it back at naruto and he gets hit by 9 of his attacks
>if his avatar is still in place, then Chojo lands and continues to hit him till he dies.
His avatar gets in pretty bad shape from 9 BDRS alone,, and he won't be launching his attacks immediately before Chojo lands, so the latter doesn't get matched this time and he can forget about doing anything meaningful when he's stuck in one place and any attack he throws get sent right back at the same spot
