But notice how he never attempts it on non-gooners
He had no real way of knowing those people were gooners ahead of time and later in the story he uses it against Kaguya who was basically the opposite of a gooner.
Not all 100 can hit him at once dude.
Not saying they can but each clone also isn't restricted to hitting him once, or to only hitting him (he has kunai for stabbing for example)
Naruto had several shadow clones out against Kaguya but when he tricked her with sexy jutsu she only got tagged by one clone before locking back in. What fight shows Naruto opening with 100 clones and then using sexy jutsu and then managing to land 100s of blows on the opponent?
Naruto never needed it. This situation is completely unlike anything Nard has faced so saying "he didn't do this in this completely different scenario so he won't do it here" makes no sense.
Most of these are after training and increasing his chakra efficiency so he can make more easier or not a fight at all. In fights like Kakashi, Zabuza, Haku, Lee, and Kiba he didn't make anywhere near that many and opted for smaller amounts or even a 1v1
Yeah usually because of the context. He basically didn't use clones against Kiba at all until the finishing blow, him fighting Lee wasn't even a fight, Haku was ******** on him too much, Zabuza was literally passive-******* them, and Kakashi was a spar against a teacher completely out of their league. Naruto had 1 direct confrontation where he got clowned on completely and that was it.
Again supes is a vastly different scenario.
How is any of that going to stop him from just flying up or down?
It doesn't. It stops him from hitting Naruto. Good luck hitting someone from hundreds of meters away while they spam speed amps, create fake copies of themselves as diversion, and throw shurikens at you.
He doesn't have to come near them at all because of super breath and heat vision, and if he does he can seperate specfic clones just by blowing ones around them away or destroying them with heat vision.
Which he's not hitting at distance and isn't really in character to begin with.
1. Prove Naruto can throw himself hundreds of meters into the air with only superhuman lifting strength
He doesn't need to, he transforms into a shuriken instead.
2. Prove Naruto can drop 500 clones when he's already spawned a large group of them to push Clark into the air in the first place
He can make 1000 of them. Making 50 on the ground and 500 more (btw that was just a random number, realistically there wouldn't be much difference between 20 and 500)should be easy.
3. If he exposes the real him like that then what stops Clark from just blasting him with heat vision in mid-air where he can't dodge and just winning
Huh? Clark would be completely caught offguard and before he can even turn around Naruto would have already swarmed him with clones.
Also technically Naruto can have a clone do that, not his real self. I just forgot which way he did it against Zabuza.
He has not done this a single time and doing this would be even more difficult than pumelling him with numbers since he'd need to be percise
You wanna know what else he's never done?
Fought someone who's not a shinobi, are 3x stronger than himself, and fly out of his range to spam heat vision while Nard himself can't access Kurama at all.
But if you don't like that one, I'd say Naruto stabbing him in the neck with a kunai works just as fine. Just less elegant
