[@dirty slime]If you're going to use the 'lol timestop' argument, then I'd have to inquire as to how time stop even works. In both the final fantasy universe/Kingdom hearts multiverse, Time stop never actually 'stops time' but rather, ceases a target's ability to move for a set period. Not to mention, time stop doesn't work on bosses, so it's clear that it can be resisted with enough willpower. I'd infer that time-stop actually affects the person's soul/muscles/gravity in order to mimic the actual stoppage of time, something that many bosses in kingdom hearts, and [i]certainly[/i] Kaguya, are/would be immune to.

Hades was clearly described as truly invulnerable while in his home, the underworld, and just like all Olympian gods [i]based on their lore,[/i] can be harmed through not-exactly-godlike-means. It's even been shown through many other universes, so using their godlike prowess as a reference is not a very reliable source of knowledge in this situation. Respecting the kingdom hearts universe, it can be argued that Sora's keyblade and magic affects the heart directly, so it could possibly harm Kaguya, but the brunt force of his magic seems incomparable, and his durability is also completely incomparable, assuring that he would most certainly get two-shotted by Kaguya.

Lightning dodging? Happens in Naruto.

Xemnas situation? I'd still argue that his ability to harm and battle Xemnas is based soley on the power of his key blade. Despite being a key-blade master, he's still human with slight advantages in speed and strength. His 'trump card' time stop is worthless against powerful beings, and his ability to harm godlike entities is based solely on whether or not he can [i]hit them enough before getting stomped.[/i]

I don't know anything about palpatine, but if he can move at the speed of light/sound then maybe he could kill Kaguya easily? Not sure how strong her perception is.
