I'm sorry, but she needed Mario's help, that's a basic fact of the game regardless of what abilities you think Rosalina might have, is it stupid that she needed help? Maybe, but the fact is, she did. You don't get to dismiss plotholes that contradict your own arguments, and yet use other possible plotholes as counterarguments.
Also, just in your post just before this one, you're stating that Mario breathing in space is just a gamplay element that shouldn't be given much thought, yet you're arguing that we can't do that with Rosalina... because?
Now you're just twisting my words.
I dismiss her asking for Mario's help as it's blatant that she could have handled the whole situation herself, and much more swiftly than Mario did. She was just written not to because Mario absolutely has to be the hero. It's worth noting that Rosalina
originally was never going to be in Galaxy as such a major character, which is likely why this plothole exists. She didn't NEED the help. She was written to ask for it despite not needing it. There is a complete difference between the two, and what happened was the latter.
However, I used possible plotholes as counter arguments to "Lumas remade the universe", because
it was never stated in the first place. I honestly don't get where this misinterpretation came from. Young Master Luma waved a solemn goodbye to Mario, as Mario, YML, and all the other Lumas, AND everything else, got sucked into a black hole, as he didn't think they'd see each other again.
That's all we saw, and the very next game, we see that YML is still the same person (and in the secret ending for Galaxy 1, we see him getting separated from Rosalina - he got left behind on Rosalina's home planet).
Also, Mario breathing in space/water/etc is simply a case of "whenever the game mechanics demand it". That's a completely different thing than you writing off Rosalina's mind control ability as "in-game so it doesn't count" (BTW, it technically isn't - it happens through a cutscene). I said it shouldn't be given much thought because it's been contradicted time and time again for two decades now, in all kinds of games. Just like "how many hits can Mario take before he is defeated?".
Rosalina's mind control is an ability that has been shown, but never contradicted. So there is no debate - she has mind control. It's a useful asset to her in battle, because mind control is literally stripping someone else OF THAT CONTROL of their own mind. That is inherently the meaning of the term. Just because she only used it once given permission for a friend, doesn't mean she could not use it as a weapon.
It really isn't relevant.
It is, it's an officially licensed Nintendo product, so it automatically is by virtue of that. Nintendo EAD had to approve her Smash moveset, after all, something they would not do if it contradicted canon.
Special exceptions are made for characters like Ness, for the purpose of getting them to work in the game. And in those cases, they are ignored, because their abilities DIRECTLY CONTRADICT canon (in Ness' case, he doesn't use the abilities he used in Earthbound in Smash - he uses the abilities of his friends).
However, Rosalina is not under the same category as Ness - her moves in Smash are new, but they fit the theme of what she is (i.e. cosmic deity, and the Mario universe's equivalent to god).
If we ignore Smash, we ignore the RPGs, the sports games, etc, and that's just in the Mario universe.
Whether or not Smash is canon is irrelevant - that merely means the fights in Smash don't actually factor into main game canon right now (except for Kid Icarus). However, the abilities in Smash are designed to be true to these characters in their canon, and absolutely no special exceptions were necessary for Rosalina. It fits what was shown of her in canon, and fits the perceived "god of the Mario verse" image the public have of her.
Except psychokinesis and mind control are completely different powers under any standard, I really don't see how being capable of one can be considered evidence in any shape or form that she can do the other.
No they are not. They both involve manipulating your surroundings in some fashion. One involves taking control of the atomic mass of an object using your mind, and the other involves manipulating the mind of another with your own (though there are many different forms of this).
On the subject of the Lumas being the cause for the reboot and all, remember, the character in Smash is Rosalina and Luma. Rosalina and her whole Luma family are in this together. After all, Rosalina does summon multiple Lumas over the course of a Smash battle, meaning it's not just one Luma that counts as the character.
The character in Smash is Rosalina & Luma because it's a way to represent the puppeteer archetype in Smash, and it just so happens to be a simple way of representing and integral part of Rosalina's character - her motherly nature. The Lumas are dependent on Rosalina for protection, not the other way around. Even Palutena and Viridi explain this in the Palutena's Guidance for Rosalina.
It's also worth noting that many players of Smash, before the recent patch at least, thought Rosalina was too good without the Luma, killing the notion that she is dependent on them even in Smash.
EDIT: And with that, I'm actually unwatching this thread. It's gotten very boring, with people constantly trying to create arbitrary rules for the sake of glorifying or underrating a character.
The reason this has happened is because a near universal agreement was actually reached in this thread on a "canon power tier list" long ago, and then it died. However, newcomers decided to re-iterate old points that have already been debunked numerous times, which revived the thread, but it's not actually going anywhere. Just going over the same tired points, leading to a completely tedious discussion.
