Garp is stronger than Bigmom and Kaido? Yes but NO, He's stronger than the rookie kaido without a devil fruit while being in the prime of his power, prime Kaido is the one Luffy fought that has mastered haoshoku and awakened his fruit, is this kaido stronger than prime Garp? Unclear, is old garp strong as present Kaido? Nope by a Far far margin

If you do not use ai art based in another's work for business then you are fine, no one can replicate gibli or their works, its just a art style and people have copied it before, it just wanst widespread because it couldnt be sold, with ai you can do at will and it will spread easily because its a machine's work while a human would need to try to train that style and wouldnt be able to get paid for that work so its not worth the effort

Franky doenst use it because he made better modifications with better tech, the time skip made a shift on their worldview, haphazard modifications with limited usefulness are left behind, brain point is forgotten because any hit from monster or kung fu point is deadlyier, weather Illusion was a one time thing against Kalifa and the fight finished with lightning to the face, Brook focused on the soul aspects of his fruit and enhanced its applicabilities instead of using for Fun, it was a change in tone for the entire cast

Naruto returning stronger than ever from a narrative standpoint is crap story telling, we know he's strong and that he's stronger than most of the current cast and much more skilled, but thats not the point, its not his story anymore, he reached peak and achieved his dream, the scorned boy rose up to become accepted by everyone and loved by all, he turned into the most powerful in-universe individual by far and he returning to his full Power would just trivialize the current threats, yes make him return but do not give him a 2.0 kurama, leave him on sage mode so as to make the consequences of events real and to not outshine the New gen, the series is BORUTO not naruto Shippuden 2
