I will close this thread as you suggested but your the one who didn't properly construct the thread to make the feats and scaling easy for those who even attempted to evaluate them. As shown below in the two comments I'm about to quote...
You changed the ratings for some reason and then you added universe level justifications to the third key but kept it at Large Star level. Then you put "Upgraded power by 100" and "Upgraded power by 500" in the keys but linked no scan whatsoever, and if you used that justification tied with the multiplier buffs your suggesting, her lower keys would be Multi Galaxy level via back scaling. I've also already talked about the last key "Universal+ likely higher " rating and you still didn't add a scan for it which makes it worse plus nothing in that description is evidence for a likely higher rating.
I'm going to propose a solution for you and it's your choice whether you want to listen or not.
You can either continue doing threads like this one and possibly get nowhere and eventually the verse will possibly get deleted. Or you can take a step back, make another thread in the future that is better structured and focuses on a single thing rather that adding planet level, star level, and universe level to a single character without clear justifications and explanations.
I'm sorry if I come off as rude but you need to understand what I'm trying to say. You even tried to use feats from another manga that while you state is connected has it's own characters and feats but without a structure for them it makes it harder to merge there feats with this one. You attempted to do to much and there doesn't seem to be many supports to help you out. I suggest you start off with one thing at a time. Such as the Synapse universe level thing. If you can provide the scans of it's universe level power with good explanation, then prove Ikaros scales to it. Other scaling could come later and if you provide those multiplier statements from her form, you could just back scale her previous states and wouldn't half to rely on scaling to characters from the Judus manga.
I will close this now. It's up to you on what you wish to do next.
