it’s much too late, of course, but:
 
Silver Age Superman was ridiculously OP, even for a comic book character, go to Superdickery and see the kind of crap DC was ladling up for their fans every month, he had a new, previously undisclosed superpower for every situation
 
Golden Age Supes was a LOT less powerful
 
they dialed his powers way back in the 80s, too
 
then in the 90s they had him killed off for a while, dead at the clawed hands of a second-rate Incredible Hulk ripoff that normally any passing Green Lantern would have just grabbed by the scruff of the neck and tossed into the sun, fight over in a single panel
 
my point is that Supes comes in a wide variety of powerlevels, you can use whichever one is best suited to the story you want to tell, ditto for Sunbutt, who got smacked down hard by Chrysalis, but who moves the planets around her solar system around with a thought

Seeing how Superman has managed to fight magically charged beings on his level, and do so on a regular basis, its safe to say that his “Weakness to magic” Is highly exaggerated. Dude beats 5th Dimensional imps whos powers would make Discord crap his pants on a regular basis, so its safe to say he can take a Pony Princess who got his ass kicked by a big monster

I said BASED On them, that’s not the same as saying they are them….

@Prof.NightJack  
“Genetics” will not let you shoot eye lasers that can destroy armored vehicles, “science” will not let you sprint faster then light. Superpower are about as grounded in reality as Zeus hurling lightning bolts or the planet earth being on the back of a giant turtle. The fact they mumble crap about a “meta gene” instead of saying “empowered by the gods” (although any number of superheroes actually are such) or whatever really doesn’t change the fact these powers are utterly impossible.
 
Compare say Hercules (Marvel version), whose power is being really damn strong and durable, to say the Hulk whose power is… being really damn strong and durable. (In fact probably more so then Hercules.) There powers are both equally outlandish and utterly impossible. The sole difference is that one supposedly came from “science”, but that “science” is so ludicrous that ultimately it’s just as implausible as, and more less equivalent to, just saying “it’s magic”.
 
In fact I purpose a new law to encapsulate this: “Any sufficiently silly science is the same damn thing as magic”
 
Just because you toss out the words ‘genes’ or ‘quantum’ instead of ‘enchantment’ or ‘mana’ to explain how you can bench press an oil tanker doesn’t make your nonsense even the slightest bit more scientific.

Methinks what he meant by that is that, when broken down to their basest levels, most if not all superpowers are like magic in the sense that they’re completely impossible in the Real World, and only storytelling allows for further explanations beyond that. Before that superpowers work because they worked, nothing more, nothing less.

>Superpower are just another word of magic  
Um.. no, some are heavy on things in like genetics and/or science in a way that you can’t say “it’s like magic”, your really dumbing the ones like that down by saying that and even some things that are magic as well by going with “they work because they work, and they work how they work because they work how they work”, that may be true but there is more to them.

Superpower are just another word of magic anyway and the same rules apply. They work because they work, and they work how they work because they work how they work.
 
Really though Celestia is boned, she might put up some kind of fight against some of the weaker versions, but she couldn’t defeat any of them really. Even the weakest versions have demonstrated way to much raw power and durability for her to hope to win.

@Keith Mowz  
Most but not all. The Source, AFAIK, is what allows for all these superpowers anyway so take it up with that thing if trollphysics is allowed.

@sigh  
Well since the infinite mass punch still works, laws of relativity do still apply most of the time.

@Keith Mowz  
You assume that the DC universe follows our own universe’s laws of physics.

@Prof.NightJack  
Okay. So then he merely breaks the laws of physics when he flies to the sun in under 8 minutes.

@Keith Mowz  
Superman doesn’t have access to the Speed Force.

@Keith Mowz  
So how does any fight against him ever last more than a split second?

Yeah, she may have magic, but he’s not just faster than a speeding bullet, thanks to the Speed Force, he’s faster than light, strong enough to haul the entire earth around, durable enough to survive supernovas (and while vulnerable to magic is still pretty durable) and a genius.
 
Of course, unless this is a Death Battle type thing where they HAVE to kill the other opponent, its not like he’s going to do anything more than subdue her.

@CMWaters
 
Only if Celestia can keep up with him physically, before his insane advantage in speed/strength overwhelms her. And nothing in the show lends evidence towards Celestia being a physical powerhouse.

Actually, there’s another factor to this fight people are forgetting.
 
Superman is vunerable to magical attacks, his invunerability unable to protect them from him.
 
For example…swing a regular sword at Supes, the sword would probably break. Swing a magically charged sword at him, you can cut him.
 
Celestia just needs to hit him with a few magical attacks and that’s it.

as much as i want to say Celestia will win, i have to give this to superman
 
super speed + super strength = K.O. before Celestia even has a chance to blink

@CMWaters  
I want to believe the artist drew the S backwards as a mistake.

Two things to keep in mind: Superman is typically portrayed as losing his powers if he goes long enough without exposure to a yellow star, and one of Superman’s very very few weaknesses is a vulnerability to magic. If Celestia can control the sun where this battle is taking place, and can hold her own long enough for Superman’s powers to fade, she’ll win. It could go either way, but my money would be on Celestia.

@CMWaters  
That explains whatever is up with the pointy lines around his eyes, too.

@igotnopicks  
Depends on the version of him, some have the same others do nto, the Smallville one got power for green kryptonite, and you know what that does to Superman.

I agree with RD.  
This would be a really awesome fight!
