Shouldn’t it also be sort of… wholesome?

Like Fire,
Hellfire,
This fire in my skin,
This burning, Desire
Is turning me to sin!

My headcanon is that every pony has different form that is either like Daybreaker or Nightmare Moon

She’s not your student, Daybreaker! SHE’S YOUR ENEMIE!

@Officer Hotpants  

 
yes yes)

Daybreaker is Celestia’s Rapidash but evil form.

So is that what she evolves into

@Magic Nova  
Battle of the heroes

@Ihhh  
yeah…that does make more sense…

@Background Pony #F5E8  
I highly doubt that they’ve planned that far ahead, especially since all of the original writing staff has left since then.

i have a theory. what if twilight wasn’t referring to rapidash. what if she was possibly foreshadowing or hinting about a certain villian that could possibly appear one day? (daybreaker)

@Magic Nova  
How about Red Sun Over Paradise?

@Background Pony #2344
 
Princess Celestia: “…and you will never exist again!”

But…Twilight did it first….lol

Twilight Sparkle in full rage mode with an flaming mane and tail known as Rapidash Twilight = The ORIGINAL Day Breaker.
 
Celestia turned villain Day Breaker = The COPY Day Breaker.
 
Sorry Celestia, but Twilight beat you to the punch years ago. The way I see it, Twilight’s the teacher and you’re the student.
 
Rapidash Twilight: “That’s MY student!”
 
Day Breaker: “Not funny, Twilight…”
 
Rapidash Twilight: “Sorry, but I was here first a long time ago before you even arrived on the scene.”

I don’t see how a simple blur effect is all that impressive. Sure, it definitely looks much better, at least in this show’s style, but any amateur with a copy of flash could just take the symbol containing the fire animation and add a blur filter to it.

You can really see the improvement of the animation quality here. Expecially with the fire.

@Firebrand96  
Do I insert ‘Duel of the Fates’ or ‘Battle of the Heroes’ here? Can’t make up my mind here…

@Alexlayer  
In a weird fanficy sort of way…

@Psy-Psichinis  
Mh, dunno. I like the idea of Sunset being Celestia’s daughter a lot more. Then again, throwing this into the fray as well could make the SunsetSparkle a lot more… “interesting” all of the sudden.

@Alexlayer  
Makes perfect sense, doesn’t it.

@Officer Hot-Pants  
Wow, I feel like this is the time I’ve seen some actual fuel for that theory from canon.

Seems legit…

The war begins…  

More fuel for the “Twilight is Celestia’s secret love child” fire.
