All right, I read your arguments for Rosalina, but none were convincing. I would have replied, but Smash World Forums acted up on me again, so I don't feel like typing all that all over again. Moving along . . .
There's not much convincing to be done, since I'm just stating the facts from the games, which are commonly accepted by the fandom. And not even all of them at that.
Feel free to provide the interview of this.

Yeah, I am doubting those because for Shadow, it's what, Air Speed Dash? Taking that literally would mean Shadow is traveling at whatever speed air travels, which varies.
The Light Speed Dash is always called the Light Speed Dash, or at least "Light Dash". Shadow is granted the move in SA2 by equipment called "Air Shoes" while Sonic gets the "Light Shoes", but the name of the move itself is the same.
Both Sonic and Shadow can do it naturally in Sonic Heroes. Shadow can also do it naturally in his titular game. And since then, Sonic doing it naturally or needing an upgrade to do it has changed regularly, but it's just obvious gameplay-story segregation at that point. Especially since, for example, Sonic Unleashed had an Xbox 360/PS3 version, and then a separate Wii/PS2 version. The storyline is identical in both versions of the game, but for some reason, Sonic needs to gain some abilities over the course of the game in the Xbox 360/PS3 version, including the Light Speed Dash. However, in the Wii/PS2 version, he has all of his moves from the beginning, including the Light Speed Dash.
The Light Speed Dash is not the only evidence of Sonic's ability to run past the speed of light, there are many instances that evidence it. For example, he outruns a black hole for a roughly 30 seconds during an in-game sequence at the very end of Sonic Colours. He did get caught by it, but the key thing here is that it's an in-game sequence, and Sonic Colours is FAR from the fastest Sonic has been able to move in-game, let alone in cutscenes. Also, in CGI cutscene beforehand, he
casually stands there as the black hole is only a few metres away from him and sarcastically comments that "this might not end well", and darts way ahead of it the moment after.
Saying Super Sonic is literally invincible and cannot be damaged is a no-limits fallacy.
...No. Super Sonic is literally invincible. This is a form that is in nearly every main Sonic game ever. Sonic does not take damage in his Super form. He can be knocked around and disoriented, but his body will be unharmed. Also, when he comes back out of his Super form, he is always in peak physical condition, regardless of what condition he was in beforehand.
Considering how the Super form tremendously enhances his natural abilities among other things, this phenomenon is likely the enhancement of Sonic's natural ability to quickly heal his wounds. It's an often overlooked detail, but in Sonic Battle, one of the game's mechanics is that the characters can heal themselves. However, the game goes a step further than that, giving each character an individual explanation for how they do it, and in Sonic's case, he "heals damage with supersonic speed" (the animation for it implies it involves him vibrating his quills to do it). For other examples, Tails uses a healing device, Knuckles uses "earth elementals", Shadow's healing ability is powered by Chaos Control, or for the most bizarre one, Amy Rose heals simply by "thinking about Sonic".
Also, healing in Sonic Battle also fills up a second gauge, called the "Ichikoro" gauge. When full, this gauge makes the characters next attack a one-hit KO. "Ichikoro" in English means "to beat hands down". So Sonic also has the natural ability to empower his attacks to a fatal level as he heals himself.
And Sonic Battle is unquestionably canon since it ties together a multitude of games in the series, both ones that exist before and after it. And Sonic's healing ability can be seen in any game where he gets beat up like crazy (such as the cutscene from Sonic and the Black Knight that I posted earlier), and seems all better moments later.
As for this Earth's core in his normal form, do you have a link? I can't just accept what you say without any evidence.
Lava Reef Zone from Sonic 3 & Knuckles is literally an entire level set inside the planet.
Alternatively, the entire finale of Sonic Unleashed takes place inside the Earth's core.
Also Sonic jumped into a volcano in Sonic '06 and screamed excitedly, as if having fun, as he did so.
