Here is one of the after the fact Chapters I was planning! I hope you guys like it, heh… I know I did!

“So, I am able to revert back to my Night Lord Form at will?” Night Claw asked, thinking about the use that could bring.

“That is correct. Celestia felt that there would be times when we’ll need you at full strength, and your pony form won’t stand a chance… Are you sure about this Night Claw?” Twilight asked, the two walking towards the Canterlot Training Grounds. “I mean, you really don’t have to do this…”

“I know you don’t want me to, Twilight, but I feel like this is something I must do.” Night Claw said, looking down at her then nuzzled against her cheek while they walked. “He caused you pain three times, three times, and I wasn’t allowed to do anything about it.” He looked back towards the training grounds entrance. “If I have to stand his presence, I rather the two of us settle it.”

“Night… You do realize he’ll probably try to cheat.” Twilight said, raising an eyebrow. “He is the Spirit of Disharmony and Chaos.”

Night Claw chuckled about the comment. “Oh, I know… You forget, Twilight. I have dealt with entities of Chaos before.” Twilight nodded, Celestia did tell her about the world he came from, and how these entities constantly attacked or swarmed their world. Also, how he sometime had to fight them himself, due to some strange incident.

“Alright…” She said, her ears lowering down on to her head as they walked up to Discord, who was nonchalantly waiting for them. “We’re here, Discord.

“About time, dear Twilight… Now, what does your Knight in Dark Armor wish for me?” The Spirit asked, seemingly quite bored. “I don’t have all day, Fluttershy and I have tea soon.”

“A challenge, Discord.” Night Claw said, catching the spirit’s attention. “Three times, you’ve harmed my Twilight… Three times I was ordered to stand down and not do anything about you.” He continued, Discord leaning in and becoming interested. “If we are to be dealing with one another’s presence, I wish to end my own tension through a way of Astartes. A duel.”

“Oooh… How barbaric of you, Mr. Claw.” Discord said, waving off the thought. “And what makes you think I would accept such a thing?”

Night Claw suddenly grinned at his words. “Easy, Discord… Are you afraid to try and fight me? Is the great Master of Chaos so scared to fight me, at my peak? Are you telling me, that the Gods of Chaos from my world, far stronger than you?” That done it, the Spirit’s attention pulled straight back to the batpony.

“What are your terms, pony?” Discord asked, his voice filled with venom.

“No magic, only physical strength and skill… We go until the other can no longer fight.” Night Claw said, magic suddenly surrounding his form, transforming the batpony into the Night Lord, his right claw raised, eyeing it. “I will not use my claws or jump pack.” He said, detaching said items, Twilight using her magic to pull them out of the way.

“And what fairness is that, Mr. Claw? Or is it Xeron right now?” Discord asked, raising an eyebrow. “Hardly seems fair that I’m going to be fist fighting with something that could shatter every bone in a mortal’s body with one simple punch.”

“To you, it will be Mr. Claw… Only Twilight and Princess Celestia may call me Xeron.” Xeron said, glaring at the Spirit, who held his hands up defensively. “And use my memory of Astartes Legions… I will allow this one time chance, so it will be equal… Per my Legion’s Laws.”

Discord suddenly got a devilish look on his face, flying up to the Astartes. “You have yourself a deal, Mr. Claw.” He said, placing a talon on to the Astarte’s helmet… Discord’s eyes lit up for a second, and his grin became even wider. “I’ve made my choice, as to what form I will take.” He snapped his fingers, Twilight’s friends, and the Princesses suddenly appeared in the nearby stands. “Figured it would be better with an audience…. A battle of gods, in a challenge of strength!” He laughed, Xeron shaking his head.

“Just take your chosen form, and let us begin the bout.” Xeron demanded, as Discord sighed.

“You’re no fun, Mr. Claw.” Discord said, before a flash of light surrounded his body. It was so bright that Xeron and all those around them had to cover their eyes to shield themselves. When it died down, Xeron suddenly got a shock he wasn’t expecting.

“You bastard…” He growled, hate filled venom within his voice, leaving Twilight in a confused state.

Discord could have chosen another Chaos Space Marine, a Dark Angel, or some random Chapter Astartes; he could have chosen another Night Lord for all Xeron cared; but no… He had to choose that kind of Astartes for him to fight. The royal blue armor, the gold outlines, the golden Aquila, and that damnable ultra insignia. “I figured having you fight the very ones that drove your Legion from their adoptive homeworld would make the most sense… Now then, Mr. Claw.” Ultramarine Discord,the visor’s eyes being his own yellow with crazed red irises, put up his armored fists, ready for a fist fight with Xeron. “Shall we?”

“You choose… What?” Twilight asked, looking up at Xeron. “What is he talking about?”

“The Ultramarines, and their Successor Chapters, drove my Legion from our adoptive homeworld, where our Primarch was buried… Seems he thought it will be amusing for me to settle things with him, by taking the form of an Ultramarine.” Xeron answered, putting up his own fists while Twilight placed a hoof over her muzzle. “Remember Discord… In battle, facing a Night Lord in close combat is considered suicide.” Without even being told, Twilight teleported away from the two, joining her friends and the other Princesses.

With that, the two Astartes charged each other! Delivering powerful, armored, punches against one another’s frames, sounds of metal slamming against metal with each strike. When Discord delivered a dangerous elbow to Xeron’s knee, the Night Lord fell down but quickly shot back up and delivered a painful strike to Discord’s helmeted chin! The group flinched, as Discord flew back and slam against the ground, sliding back. “Is this all you have, Discord? I thought you would be much stronger.”

Discord sat back up, rubbing the chin piece of his helmet with a forearm. “Please, Mr. Claw… Give me a moment to regain my old fisty-cuffs skills and I’ll show you a thing or two!” The Ultramarine charged forward, recovered from the near knockout punch, and landed a punch to Xeron’s stomach, then followed with a direct hit to the faceplate!

Xeron backed up, shaking the daze off from the attack but soon found himself under a barrage of punches from the Ultramarine Discord, and unable to defend against the flurry of attacks. Twilight winced at each hit he received, holding both forehooves over her muzzle. She didn’t want to watch, but something kept her attention on the fight. “Come on, Xeron… Fight back…” She whispered, watching the Night Lord taking far too many blows from the Ultramarine Discord.

“At this rate, he’s going to get knocked out!” Rainbow Dash said, actually starting to panic. “Discord is moving too fast for him!”

“Ah know, ah didn’t know Discord could move that fast, or if one of them Astartes, as Xeron calls’em, could… That there armor seems ta bulky.” Applejack said, sharing Rainbow Dash’s concern. “His pride and honor be at stake, since he was the one that called fer this little show down.”

“Agreed, laides… Despite how brutish the challenge seems, Mr. Claw should not lose… After all, he’s doing this for Twilight, from what I understand.” Rarity said, fanning herself with a hoof.

“COME ON NIGHT! BEAT DISSY UP! FIGHT BACK!” Pinkie Pie screamed, bouncing up and down with midnight blue and red pom-poms… That no pony knew where she got…. Along with a shirt that had Xeron’s helmet next to a #1…

Just as Xeron took a punch straight to his stomach, Discord landed pay back punch to Xeron’s chin! Sending the Night Lord back and skidding across the arena…. His boot keeping his armored body up. “Seems like Sir Night Claw underestimated Discord’s ability to fight.” Luna said, looking up to Celestia. “Sister? Should we worry about his health?”

“No, sister… Since this is about Twilight, I doubt Xeron will allow himself to lose, in front of her.” Celestia said, making something click in Twilight’s mind.

“Come on, Xeron! I know you can win!” Twilight shouted, frantically, as Ultramarine Discord charged towards the nearly beaten Night Lord, readying one last devastating punch. “Xeron!”

Her words ringed within the Night Lord’s audio sensors, his gaze locking on to the charging Ultramarine then, when he heard Twilight call for him… Something snapped within his mind, the visor of his helmet lighting up. The moment Ultramarine Discord swung, Xeron grabbed hold of his armored fist, his grip starting to break the ceramite armor. “Time to end this…” He growled, before slamming his knee into Discord’s stomach, causing him to hack out and try to gasp for air. While Discord was bent over, Xeron grabbed his helmet and slammed his knee into the face plate.

Discord started to back up, dazed from the strike, but could not respond fast enough. Xeron was already on top of him, delivering more devastating blows to his chest, stomach, and faceplate. The group, in the stands, started to cheer at the Night Lord’s second wind! Discord was now on the defensive, and Xeron was moving far too fast for him to put up a proper defense.

When Xeron slammed a powerful punch to Discord’s stomach, again, the Night Lord gripped both hands together, holding them up. “YIELD!” He roared, before slamming the hammer-like strike down on to the back of Ultramarine Discord’s helmet! The moment he collided with the ground, the tiled ground suddenly cracked due to the force of his impact.

Blood spat out of his gorget, Discord slowly bringing himself up, his arms shaking. “Discord, Lord of Disharmony and Chaos… Never… Yields.” He growled before Xeron delivered a powerful kick to Discord’s head! Sending the fake Astartes flying back and slammed into the ground.

“Yield…” Xeron repeated, more like a demand now, watching as Discord slowly stood back up.

“Never….” Discord growled back, summoning what strength he had left. The two charged one another, once more, ready to deliver a punch to their opponent. When they got close enough, the two swung… Discord finding his punch failing, falling down, as Xeron delivered a bone crunching strike against his helmet! This caused Discord to fly back, royal blue pieces of metal flying off of his helmet, and then painfully crashed against the ground.

A few moments passed, the fake Astartes didn’t budge an inch. The group wondered if he was planning something, but their thoughts ended when Discord’s transformation spell faded and revealed the draconequues’ form. With that, the group cheered, even the Princesses, as the Night Lord stood victorious. “He did it! He won!” They yelled, Twilight teleporting next to the Astartes, as he slowly transformed back into a batpony… His body covered in bruises.

“He… Put up… A better fight than… I thought.” Night Claw said, between breathes, as Twilight nuzzled into his neck.

“You had me worried he was going to knock you out!” Twilight complained, looking up at him. “It wasn’t that long ago that you woke up from that coma, too! No telling what damage all this could have caused.” She gave a pouting face, as Night Claw raised an eyebrow.

“Then it is a good thing I heal fast.” Night Claw noted, before kissing the side of her cheek. “Though… Wouldn’t mind having you as a nurse.” He teased, making her blush.

They were interrupted, when Discord, weakly, held up a taloned finger. “I-I… Call… For a rematch…” He managed to say, before his arm fell back down.

“When we’re both healed, I won’t mind another duel with you, Discord.” Night Claw said, smirking a bit. “For some reason, wailing on you puts me in a good mood.”

“Ha…Ha…. Ha.” Discord, sarcastically, laughed before passing out.
