Daybreaker vs. Joseph Joestar! A pointless power difference.

What makes a villain powerful? Is it their abilities, their mindset or their determination? Well, to answer your question it doesn't matter because one of the most powerful of said villains has unfortunately returned. Fast forward to Ponyville, where Twilight Sparkle's library has just been set on fire in a small explosion. She drops everything she was levitating, an incredulous and sudden look of shock and horror creeping onto her face at an accelerated acceleration.

!...
Nothing in here is flammable, how could this be??

Twilight didn't have much time to think, as the fire was spreading up to the second floor. She spread her wings carefully, checking they won't just spread into fire and be a helpful extension into turning her into a pile of useless ashes. She flapped up in great control, before descending down to the exit. Luckily, she was the only one in the library at the time. She burst through the door, before watching in silence as the library crackled and burned. A few minutes later, she had called over her friends, and Discord plus Starlight Glimmer. They all stood infront of the now nonexistent library, but only Discord seems to be missing.

Just as they thought Discord would be a no-show, he teleported into the scene, a sly expression on his face.

So, what seems to be the proble-

His eyes snapped to where the library used to be, as it kinda was out of place that every other building was still there.

Oh.

Everyone simultaneously gave her a look, trying to assess what exactly happened here. Twilight recognized their looks of curiosity, and spoke with a disappointed tone.

It just.. started burning. No windup, no nothing.

Her gaze averts from them all, before snapping to where the library used to be.

That's.. that's centuries of knowledge just.. lost!

Applejack chimed in next, a skeptical but believing look on her face. Twilight wouldn't lie, would she?

Yer sure it just burst into flames? This ain't just some jaw wobble as a practical joke?

Fluttershy shared a look with Starlight glimmer and Rarity, while Pinkie Pie was uncharacteristically silent and Rainbow Dash simply stared at the library. Oh, and Discord was floating in the back, now trimming his beard with a pair of scissors made from blades of grass that he probably put together in an instant. After a moment of silence, Twilight finally replied to Applejack.

Yes!...

Discord noticeably started paying attention, the unnaturally sharp grass scissors he was using shortly flung into who knows where. Starlight Glimmer promptly walked near the library, her horn lighting up dimly. After a few seconds, she spun around to face them all again, an unsure look on her face.

I don't know Twilight, this fire seemed to have come directly from the sun. There's only a few ponies who could have done this. Wait a second, infact there's only two who could have done this!

The entire group leaned closer, now invested. Twilight spoke up first, the disappointment on her face turning into mild anger.

Oh? What is it?

Rarity squeezed in next, the group speaking after one another like a line of conga.

Do tell! This place was rather important to me.

Pinkie Pie finally spoke for the first time during the whole conversation, too.

Tell me tell me tell me tell me!

Rainbow Dash grudgingly chimed in, her wings flapping as she muttered under her breath.

It's probably the Gods of boredom recognizing the stupidity of books.

Everyone shot Rainbow Dash a glare immediately, including Discord. Rainbow Dash spoke up defensively, throwing her hooves out.

What!? It was just a joke.

Starlight Glimmer brushed off Rainbow Dash's words dismissively, before continuing to reveal her assessment.

Remember when i told you all about the time that Princess Celestia and Princess Luna switched cutie marks?

Everyone gave Starlight Glimmer a wide-eyed horror, except Discord who was now having a bunch of brightly coloured polka dots fly around him like a mini-orbit. Twilight rushed with her words, fearing the fact that Celestia's sinister counterpart may be trying to get a way into Ponyville.

Quick! We need to tell Celestia, she'll know what to do!

Starlight Glimmer looked at Twilight nervously, noticing the rush in her tone. She opened her satchel and threw Twilight the magical letter book. Twilight took no time and lit up her horn, scribbling a letter frantically. She put down the quill and looked up from the book in a huge panic.

Does anyone know where spike is?!

Fluttershy anxiously stammered up, her voice taking on a bad-news tone as she fidgeted with her hooves with her eyesight focused on the ground.

Uhm.. he's.. he's in your house, is he not Twilight?

Twilight closed the book and immediately spread her wings. She let out a quick sigh, before speaking in great relief.

Great, i just need to find him, and then he can send off this lett-

To everyone's surprise, the letter in question burst into ashes. Not flames, but ashes. It was as if whatever caused the fire did it in a jiffy. Their heads snapped to where the Library used to be to see where the flame came from, before seeing none other than what they dreaded: Daybreaker.
