Seems very u fair to give someone like Ichigo duh a large power up when he was literally ragdolled by Ywach n only beat him due to plot arrow. You're upgrade Almighty and GoD tiers based on the novel of prime Si destroying a hollow planet sized monster, n Ywach absorbing DK n becoming more powerful. I was told before that we don't use novel feats and instead we use scaling. If that was the case Naruto and Boruto god tiers should've been upgraded to star level based on Momoshiki and Kinshiki collapsing a star in the novel of Boruto. So, in the Boruto novel 3 shinobi no yoruMomoshiki destroyed a star. The novel mentioned the sun was dying, confirming Momoshiki destroyed it. I could go as far as saying the star was undergoing a supernova; the novel stated "the dying star emitted a synchrotron radiation." A synchrotron radiation encompasses a light that is more than a billion times greater than the light of the sun. Similarly when a star explodes, It suddenly increases in brightness by a factor of many billions times. According to this a supernova does in fact emit synchrotron radiation. Ergo, Momoshiki destroyed the star by triggering its supernova. Following, this particular novel is part of Boruto Naruto Next Generation official timeline, positing it's canon. Possible rebuttals. "This is an outlier feat" Except Momoshiki has other feats that opposes the case. In Boruto episode 65, Momoshiki asserted he created his nursery. Keep in mind nursery is a term used by the Otsutsuki clan to refer to planets. So basically, Momoshiki created a planet. Momoshiki was suggested to be stronger than Kaguya (Sasuke stated Momoshiki and Kishinki were the pursuers Kaguya was afraid of), who was going to destroy a planet, and the space surrounding it. It was also heavily implied she created several planets, one of which contained the dual moons. There's also the fact Momoshiki has eaten more chakra fruits than Kaguya from several god-trees, meaning he has acquired more power. "If Momoshiki could cause a supernova, why was he defeated so easily." He was defeated when he dropped his guard. Pay no attention to the movie; in the Boruto novelization (It should be noted this novel is currently being incorporated by anime) when his Rasengan, and Boruto's Rasengan amped by Naruto clashed, they both varnished. Momoshiki then laughed and taunted his opponents, satisfied he had negated Boruto's Rasengan. Unknowing to him, Boruto's Rasengan didn't exactly dissappear, it simply wasn't projected physically. The Rasengan thus swallowed Momoshiki whole while he was taunting his opponents; when his guard was down. Additionally, the Otsutsuki are known to be susceptible to harm when they drop their guard.
E.g Kishinki got kicked by Kurotsuchiwhen he dropped his guard. Kaguya was blitzed by Kakashi, which caught her by surprised signaling she was off guard. "Why didn't Momoshiki oneshot the Kages" Momoshiki had no longer had any offensive attack. Sasuke specifically addressed this. "Why didn't he oneshot Naruto and Sasuke" Naruto and Sasuke were superlative ninjas, in the sense their abilities were of the highest degree. Momoshiki was an incompetent in comparison as he lacked knowledge in rudimentary training. Basically, he didn't know how to fight. Coupled with the fact his speed was similar to that of Naruto and Sasuke, and the fact he had no offensive attack, he couldn't overcame them. "Does Naruto and Sasuke scale to this feat" No they don't. Momoshiki was stronger than them. The anime summary mentioned that Momoshiki exhibited powers not inferior to Naruto and Sasuke. Then the anime added these power obtained are greater than Naruto's. In fact, Momoshiki looked at Naruto chakra, and still called him fodder. Conclusion. This feat at very least pegged Momoshiki at Solar-system level which makes sense, again, considering he's stronger than Kaguya, not to mention he has eaten more chakra fruits than her.
