As soon as they hear Discord shout "GO!", Luna materializes two magical swords the same color as her magic and charges at Sweetie Belle.
Sweetie Belle immediately separates her weapon into its ten cannons mode, then turns five of the cannons into beam swords.
Two of the beam swords clash against Luna's magical swords, and Sweetie slashes at her with her three remaining beam swords, only for Luna to teleport away. When appearing, the princess fires a few magical beams at the filly, only for Sweetie to cover her hoof in energy before swinging it to deflect the beam. She then counterattacks by firing her own beams at the princess from her cannons and her horn.
Luna flies out of the way of the projectiles, revealing to be really fast! But she still almost gets rammed by a shield coming from above, leaving her with no choice but to teleport again. When she appears, she fires a giant charged magical beam, but the filly simply avoids it by jumping to the side before trying to ram the princess with another shield.
Luna avoids it again by charging at her, magical swords ready. Sweetie Belle readies her swords too, but then, Luna teleports and appears behind her, almost slashing her back. The filly quickly acts and is able to block her with a shield that still gets destroyed by the power of Luna's swords, but this gives her enough time to get away while firing with her cannons.
Luna then turns into a cloud of shadow, causing the projectiles to pass through her before she reforms. But before she knows it, a whip wraps around her neck and slams her on the ground. She quickly recovers and plunges the area in darkness, totally blinding Sweetie Belle.
So the filly closes her eyes, then lowers her head to avoid a first magical beam, then moves it to the right to avoid another. She takes one step back, avoiding a third beam, then swings a hoof to deflect a fourth right back at Luna in the sky, taking her off guard.
Again, she quickly recovers from the hit and cancels the darkness. Using her magic, she then creates from Sweetie's shadow a spike of shadow, forcing the filly to fly into the sky. However, here, the princess gathers some clouds and starts using them to shoot lightning bolts, but Sweetie Belle manages to avoid all of them.
Getting annoyed, Luna calls the power of the Moon and sends from the heavenly sphere a huge and very powerful beam that causes a huge amount of dust to rise and form a cloud. Not sure if her attack touched, the alicorn remains on guard.
So when Sweetie Belle comes out of the cloud of dust with barely a scratch, Luna immediately fires another charged beam at her, and the beam engulfs the filly, only for her to break into shards of glass, to the princess' surprise. The real Sweetie Belle then comes out from below and rams her in the belly like a fiery comet, sending both of them high.
Sweetie Belle materializes a shield for Luna to slam against, then immediately starts to attack her with a storm of dozens of attacks. After a dozen seconds of this, Sweetie Belle rams Luna from above and they both return to the ground like a meteor, forming a big crater.
Smirking, Sweetie Belle then uses Luna's own shadow to create tendrils of darkness and uses them to trap Luna on the ground, making sure to wrap one around her horn and to tighten it just enough to stop her from using magic without breaking it. While Luna struggles against the tendrils, Sweetie Belle then flies up and fires an Ultimate Doom Laser.
Luna can only look in horror at the beam before it hits her and creates a huge explosion that causes another cloud of dust to appear. Sweetie Belle uses some wind to blow it away, revealing the unconscious body of the princess.
This leaves everypony watching the fight absolutely speechless.
"She... She defeated her... so easily..." says Celestia.
Discord picks up his jaw. "And she used some tricks she never used before. She's still learning new ones? Oh well. She won. Not a big surprise." He snaps his fingers, creating a white shirt with written on it 'A filly kicked my flank'. "Let's heal Moonbutt and give her this."
"Agree!"
LoL
Also, the lore- cool!
I mean, she got her own chapter, most full-on bosses just got lumped in with their stages. She also, you know, actually put up something resembling a fight, and that's more than Discord expected.

True. XD Like Sweetie said back in the Return to Dreamland Arc, Luna may not be the most powerful alicorn (this title goes to Celestia), but she's the most skilled, so yes, Luna was able to put up something. Too bad for her, Sweetie was much more skilled and had some tricks up her sleeves.
...You know what? I know this isn't quite accurate, but I'm still gonna say it. "Luna used Moongeist Beam!"
Sweetie unleashes her full force Z-Move! Never-Ending Nightmare

And also a bit of this near the end.

Max Malicious Moonsault? More like Max Magical Moonsault!
Tbh, I wouldn't be surprised if something similar happened if Luna fought even Dedede or Meta Knight. Seriously these characters are absolutely insane.

True, lol.
Edit: after rereading this chapter and doing some thinking, I'm not sure that Dedede and Meta Knight would have managed to defeat Luna. In the story, I compared the power level of an alicorn to the one of Marx, and Dedede and Meta Knight couldn't defeat Marx yet. So a victory against an alicorn as skilled as Luna seems unlikely.
Hrmmmmmm speaks with discord and gets a entire merch line before sending it to the dream universe
NI cinco minutos duro esto, pobre luna jeje
