I don't see any of this, really.
"Superior to the Smash version of the Creation Trio"
I don't agree with this statement at all. Trophy descriptions don't really mean all that much since they usually specify the version of the character they mean, the Creation Trio trophies in both Smash 4 and Brawl list these characters as the Sinnoh versions of the characters (Sinnoh doesn't exist in Smash world, no reason to believe it does). Master Hand doesn't own the trophies either, the player is the one who collects them. I don't see a reason to believe otherwise. And for proof of what I mean by "the trophy version of the character isn't necessarily the smash version" let's have a look at Melee's trophies.
The first one talks about Mario (which is credited to the game he first appeared in) outside of Smash while the second one talks about Mario in Smash crediting him to Smash.
"Embodiment of creation and embodiment of destruction" This statement is way too vague to be used, you could call someone like a boxer "the embodiment of pain" and it wouldn't mean they've created and control pain. Calling something the "embodiment" of something doesn't mean they are that thing exactly. It's way too vague. Plus, if we're assuming that Master Hand is the "embodiment" of creation means he created everything then that means Crazy Hand destroyed everything, which, doesn't make sense since the universe is still there. Keep in mind that the "embodiment of creation" isn't even the quote, it's "source of creation" in the US and "personifies creation" in the EU, showing that it doesn't even mean that much to begin with (both of them are translated from Japanese, so it would probably be better to find the original source is what I'm saying.) Source of creation could just mean he creates a lot of things.
"Create and ruled everything in Smash, even the intro of SMB 64 is enough for this."
Except for Tabuu and Subspace which are part of the Smash universe but ok. Also, there was already a room (or a universe) before Master Hand brings everything to life in the intro of 64, there's not really any proof he did anything other than transforming the space. The rest of the "proof" that Master Hand is universal is vague statements that don't mean much.
"Sonic is a walking plothole who appear from nowhere"
Which kinda brings up a problem with the next statement.
"-Subspace and World of Trophies are clearly different space. Subspace isn't in World of Trophies and Tabuu can't go outside Subspace because of being it's embodiment."
Again, being called the "embodiment of pain" doesn't mean you can't leave pain or something stupid like that. But yes, Sakurai did say that Tabuu can't leave Subspace and whatever, but that's extremely inconsistent, let me just quote the Smash Bros wiki for a moment.
"Presumably, one cannot pass from Subspace to the real world (or vice versa) if there are no rifts. This, however, brings up multiple plot holes.
- No rifts are known to have existed before the story begins. This raises the question of how Tabuu was able to bring Master Hand into Subspace to begin the story, or how he was able to mobilize the Army from Subspace onto the Isle of Ancients.
- It is unclear how Dedede learned of Tabuu's nature and Off Waves, given that he would have to enter Subspace to do so (as Tabuu cannot leave Subspace).
- It is never stated or shown how Sonic ended up in Subspace in the first place.
- It is unclear how the Smashers managed to escape Subspace after Tabuu's defeat, as all the rifts that can be traveled through had been closed."
There. That p much shows it.
The page also says "the universe ends when he's beaten" or something along these lines, however, I don't know where that comes from. Considering that the universe is there with the same locations shown a lot of the time in previous games or that Tabuu beats Master Hand on camera and the universe doesn't stop working and whatever.
