Part 2: The Alien Mis-Match

The two princesses continued staring in shock as Ben had to facehoof himself in the face not contemplating on how many ponies he had to explain this story to. He sighed and came forward as he did a courtesy bow when both sisters lowered their gaze towards him.

“It’s a pleasure to meet you, your Majesties. I’m Ben Tennyson…and this whole ordeal is somewhat my fault,” Ben stated.

“Did you turn our royal subjects into these monsters?” Luna asked with a hesitated glare.

“Not directly if that’s what your thinking,” Ben replied as he scratched the back of his mane.

“Calm yourself, sister. We must let him explain this situation before jumping to our own conclusions,” Celestia explained.

“Thanks. Me and my friends, who are named Gwen, Kevin, and Rook, accidentally came here by some unknown means. It’s a little hard to explain, but we aren’t from this world per say and definitely aren’t ponies by choice,” Ben stated.

“He’s from another world where they are humans and what’s known as an alien. He has a device on his wrist that lets him turn into different species of creatures. He was gonna demonstrate for us before Pinkie had to get excited,” Twilight added as she came forward ruffling her wings.

“I just wanted to press the button!” Pinkie defended.

“We came over and some sort of green bean of energy turned us into these creatures. He had no control over his watch so he’s not the one to blame,” Twilight finished.

“A device that turns this colt into…aliens? What even are those?” Celestia asked.

“Look! We are heroes from another world and we kick a lot of butt! Is that enough of an explanation for you?!” Kevin yelled which made both alicorns gasp in shock at the demanding tone.

“Kev! Are you trying to get us killed?!” Ben yelled at his best friend pushing him back.

“To put what my…friend here said in actual diplomatic words…we’re lost, we’re confused, and we’re stuck,” Gwen added.

“Well, I can firmly see it wasn’t intentional so I believe you, Ben Tennyson, but our lack of knowledge on other worlds outside Equestria is very limited. Also, we know more about magic then actual technology as Equestria has very little use for it. I’m afraid we will be of no help to you all,” Celestia explained.

“So, we’re stuck here forever?” Ben asked.

“I wouldn’t go that far,” A echoing voice replied as a blue mystical portal opened up as another pony made their way out into the throne room.

This pony was an earth pony with a short jet black mane, goggles with green lens around his neck, a white lab coat with a yellow trim decked out with bronze epaulettes, brown shoulder pockets, a buttoned-up brown vest, four brown boots on his hooves, one of his front hooves having a metallic glove on, and a cutie mark of a pocket watch. The four otherworldly ponies gasped as they saw who it truly was.

“Professor Paradox?!” Ben recoiled falling on his flank.

“Surprised, I see. Yes, yes, it is. I have to say that alternate reality physical features are very peculiar,” Paradox replied as he looked over his new appearance.

“Ah hate to spoil this reunion, but who’s this feller?” Applejack asked.

“I’m Professor Paradox, Miss Jack. A time walker to be more exact as I can walk through many timelines seeing many pasts, presents, and futures,” Paradox replied.

“How did you know her name? And time travel?!” Twilight recoiled as she backed up in surprise.

“Ah yes, you would know what I’m talking about after the very reckless actions by Miss Glimmer. I would tell you to keep a close eye on your student,” Paradox suggested as he walked passed Twilight.

“How did you get here? I thought you only walked through the timelines of our universe,” Gwen stated.

“Gwen…I can travel between dimensions and explore various spaces of time as I please, but just like any human dweller, I am forced into the form that universe demands. I seen you needed help when the whole Earth was about to blow up and shifted you all to another dimension entirely,” Paradox explained.

“You’re the reason we are here?” Kevin asked as he jabbed a hoof at Paradox.

“That’s correct. Your timeline is inhabitable after it’s destruction by the blast that sphere caused,” Paradox replied.

“So we have no more home?” Rook asked with a shocked look.

“Grandpa Max?!” Gwen added as she hugged Kevin.

“My parents? Everyone in Bellwood? They’re all gone,” Ben replied as he looked down with his head.

Twilight and the rest of their friends felt a little teary-eyed as well knowing what could happen if they lost their loved ones. Twilight came over and helped Ben back to his feet levitating a handkerchief over to his eyes to dab them of tears.

“Yes, a tragic end that is, but it’s never too early to save them. With my assistance, rescuplting time will not be too much of a challenge or there’s the benefit of depositing you all to another timeline exactly like yours,” Paradox explained.

“Kinda hard to transport us anywhere else since we don’t have a way home now,” Kevin stated.

“That comes later. I can’t give you the main details, but you’re about to serve a much bigger purpose here,” Paradox explained.

“How would you-wait, a bigger purpose?” Ben recoiled as he looked at Paradox

“How is something like that possible?” Twilight asked as she looked equally as shocked.

“The many wonders of inter-dimensional travel allows me to explore anything in full view and as it were to happen, there’s multiple timelines where this sort of accident has happened. Each much different in context, but similar in execution. Equestria is on a path of war in each timeline and this one may have devastating consequences if you were to leave now,” Paradox replied in a very serious tone.

“Serious consequences…?” Twilight wondered as she held her head down to think.

“Not like it’s anything different from the normal baddies we faced,” Spike added.

“Yet we shouldn’t take this dire warning as anything different. After the changeling forces kidnapped me and my sister along with the rest of Ponyville and Canterlot, I made an oath to take any threat seriously no matter how little we would pay in the end,” Celestia explained.

“Then we have yer back as always, Princess,” Applejack declared as she nodded her head.

“Yeah! We won’t be taken by surprise anymore, because only I do the surprises around here!” Pinkie exclaimed.

“Consider this a free one. You have a crisis to attend to. Ta-ta for now,” Paradox explained as he checked his pocket watch before disappearing in a blue flash.

“What did he mean by that?” Spike asked as a huge rumble shook from underneath the castle putting everyone on edge.

Celestia and Luna kept themselves steady on their hooves as they had fearful expression on their faces as they darted their eyesight over to one another.

“The gem vault!” Celestia exclaimed.

“Who could be trying to break into that vault for a bunch of gems?” Discord asked with a thoughtful expression.

“Diamond dogs,” Spike answered as everyone gasped not hearing that name in a long time.

(Scene Break)

The royal guards were fighting a whole horde of big muscular dogs in silver armor armed with spears outside the castle gates, but the rumbling heard was down in the caves below as a dog wearing a red jacket used giant boulders on the lock mechanism of the turning wheel for the vault.

“Are you sure this is working, Rover?” Spot asked as he came up to his fellow leader.

“You got any better ideas? I’ve been at this for an eternity and I’ve only managed to crank this thing a few inches,” Rover replied.

“Maybe we should find bigger boulders?” Fido recommended as he stroked his chin.

“Argh! These are useless! The entirety of Canterlot’s gem valuables and we are gonna pull off the heist of a century even if I’m running to the end of my chain to bark. It’s always worse than my bite,” Rover declared as he walked his past his partners.

“And with our forces keeping the guards busy, no one should suspect us down here,” Spot added.

Suddenly, a long slender body appeared from the rocky ceiling as Discord slithered down in a snake formation and appeared right in front of the Diamond Dogs smirking startling them as he returned to normal.

“Discord! What are you doing here?” Rover asked.

“Just seeing what you boneheads thought what you were doing and clearly you didn’t think ahead of this plan,” Discord replied.

“Aren’t you supposed to be in solid stone or something?” Spot asked.

“Let’s just say that won’t be happening anytime soon. Unless Princess Celestia decides that harsh punishment for you,” Discord replied.

Discord snapped his fingers bringing Twilight, Fluttershy, Pinkie, Spike, Ben, Kevin, and Gwen to his presence as they all stood ready against the trio.

“Diamond Dogs! What do you have to say for yourselves?” Twilight asked as she stood up front.

“The Princess of Friendship?! Oh boy, we’re in the doghouse now!” Rover exclaimed as he fell on his backside.

“First villains to acknowledge that their toast,” Kevin muttered as he stared at the dogs unamused.

“Oooh, toast? DISCORD, TURN THEM INTO TOAST!” Pinkie screamed which echoed in the underground caves as crumbles of rock fell from the ceiling.

Medium-sized rocks fell to the floor giving the dogs an idea to fight back as Fido started picking up two rocks at a time throwing them at their adversaries as Spike created fireballs to counter the rocks from hitting his team. Ben tried fiddling with the Omnitrix to get it working, but he only got green electricity in return. Gwen created a mana shield with her horn blocking out the rocks while Spike released his dragon breath melting the rocks.

“We ain’t gonna be able to hold them off like this forever!” Gwen exclaimed.

“Then let’s get rough!” Kevin added as he absorbed some stone and ran punching rocks away heading for the Diamond Dogs.

Spot got slammed into the side of the cave as Fido blocked shots from Kevin, but Kevin hit a double punch to the face slamming him into the other side. Rover sweated a little bit as Kevin smirked coming up just as Ben saw more electricity coming out of his Omnitrix before another green beam shot forward reaching Rover. Kevin gasped and got blinded by the green light as Rover’s body started changing.

Rover’s body started growing as he became more muscular and grew green diamond-like rough skin as his eyes became fully yellow as large diamond shards stuck out of his back. His feet and claws became sharper as he laughed looking at his new form.

“Hahahahahahahahaha!!!!! Whoa, talk about a being stuck between a rock and a hard place!” Rover boasted as Fido and Spot both gasped at the appearance of their fellow leader.

“Ben! What the heck?! Why’d you turn this mutt into Diamondhead?” Kevin exclaimed as
Rover reared back a fisted claw sending Kevin back to his allies.

“Just what we needed as well,” Twilight muttered as Spike sent a stream of fire at Rover, but Rover summoned a wall of green diamonds letting the fire fizzle out quickly.

“My fire isn’t having any effect,” Spike observed.

“That’s because he’s Diamondhead or a Petrosapien. He’s resistant against any kind of energy and can even absorb it all to send it back at us,” Ben explained.

“So we can’t hurt him?” Spike asked.

“I’d take that explanation alone as a yes,” Discord replied.

“Wait…you said I could do the same thing…so if I blast Rover, then I can just push his energy back at him,” Twilight concluded.

“Two energy resistant beings could create a cataclysmic shockwave. It could cave us in,” Gwen warned the Princess of Friendship.

“Sorry Gwen, but if I don’t do something, the whole vault is going away with these thieves,” Twilight stated as she charged up a rainbow surge of magic.

Twilight fired a stream of alicorn magic as Rover stuck his hands together growing a green diamond shield as the offense struck the defense allowing Rover to absorb the energy. He giggled redirecting upwards as the blast went through the ceiling of the cave as a large hole showed everyone under a gold grand ballroom. Rover fired large shards of diamonds at the group as Gwen creates a mana shield over her, Ben, and Kevin while Twilight flew away. Discord and Fluttershy used their slender bodies to slip through shards as Pinkie got impaled in the back, but easily used her slime body to reattached herself together giggling and bouncing around the place.

“He’s too strong! I can’t use magic to shake him!” Twilight exclaimed.

“Come on, you dumb watch…I need something from you!” Ben complained as he slammed down on the watch.

Omnitrix malfunctioned. Life forms are unavailable. Primary functions are unavailable. Possible shutdown is recommended,” The Omnitrix spoke back through a glitchy tone.

“Well, there goes our main weapon,” Kevin stated.

“Wait…Ben, what if you reset everything?” Gwen asked as she created another mana shield that was already cracking due to the shards.

“Reset? I could break this thing more than it is now,” Ben replied.

“What I mean is….urgh…reset the cycle and set everything back to default…maybe recalibrate the DNA from everypony,” Gwen suggested as she created her third shield, but the magic was taking a lot out of her.

“Like the Highbreed…they had blank DNA and you used the Omnitrix to reset their DNA using some of your own forms. Maybe you can take back DNA in this case,” Kevin explained.

“Better than no plan, I guess. Omnitrix, access recalibration, command code override,” Ben ordered.

Command system override complete. Omnitrix recalibration functional. Would you like to reset device?” The Omnitrix asked.

“Recalibrate Petrosapien sample. Code 000 Recalibrate 0,” Ben ordered as a green beam started appearing from his watch.

Petrosapien sample selected for recalibration. Choose form to switch to default setting,” The Omnitrix instructed as Ben saw Rover beginning to swing around him.

Kevin went out there to distract him punching back at the leader of the Diamond Dogs getting some punches in, but ultimately, he got swatted away with one rough claw. Discord snapped his fingers creating a blaster with a red foam cover over it leading to a big container of chocolate milk as he put some goggles over his eyes with orange lenses. He flipped a switch on the container blasting a wave of the brown substance drowning Rover in the milk. Ben came up shooting the green beam building from the Omnitrix blasting Rover as the Diamond Dog started shrinking.

“What are you doing?!” Spot exclaimed as he held his head.

Rover shrank back down as all the diamonds started crumbling to smaller pieces and his grey skin returned. He looked at his form returning to normal as he fell on his bottom and felt his vision becoming a lot more blurry.

“Oh, I don’t feel so goooooooddddd…,” Rover stated with a woozy voice and his face turning dark green.

Petrosapien sample recalibrated and returned to Omnitrix. Default settling enabled,” The Omnitrix reported.

“Sweet! I guess you can teach an old dog new tricks,” Ben stated.

Kevin walked up to the dog trio as they all were fearful of the stone-covered earth pony as he smirked at their trembling frames. He took Spot’s head and Fido’s head as he clonked all three heads together effectively knocking all three leaders out.

“Now, stay down,” Kevin ordered as he returned to his normal form.

“That was so much fun! I was all squishy and bouncy and floppy and gooey!” Pinkie exclaimed.

“That was a little too real. Can we go back to normal?” Fluttershy asked as she fiddled with her tendrils.

“I don’t know about that Fluttershy. I could always use a fellow slender friend to chat around or have adventures with,” Discord stated as he stroked his small beard.

“But I don’t want the animals to be afraid of me!” Fluttershy protested.

“Ah found them down here, Rook!” Applejack exclaimed as she hopped down in the hole with the Plumber cadet as they landed while throwing dust in the air.

“We were helping the royal guard fend off their dog soldiers and it looks like the field is clearing out,” Rook stated.

“Not to mention, this form gave my bucking a super charge. Ah was kicking those dogs left and right,” Applejack added with a smirk.

“Well, you won’t have to worry about being aliens forever. I found out what was wrong and have a chance to correct the wrongs,” Ben stated as he pointed to his broken Omnitrix.

(Scene Break)

Back in the main throne room, Princess Celestia and Princess Luna sat atop their platform as Ben finished changing Twilight back to normal letting the Omnitrix shuffle the alien samples back into the database. Ben then tapped on the Omnitrix seeing the familiar green wheel of selected aliens, but it shut down quickly going red.

Recalibration is complete. Alien database reconfigured and set to default mode. Shutting down for recharge,” The Omnitrix explained.

“I knew that was going to happen,” Ben stated.

“I’m just happy to be myself again. It felt cool and all being made of fire, but I’m better not being a living barbecue,” Spike stated.

“As much as I love plants, I’m glad I am not one no more and I’m so glad I didn’t accidentally hurt anyone,” Fluttershy added.

“It wasn’t all bad, you two. Not the ideal animal I wanted to become, but that feller sure packed a kick in his steps,” Applejack stated.

“I just miss being a squishy body alien,” Pinkie added with a sad expression.

“I want to congratulate all of you in your efforts in making sure that The Diamond Dogs did not success in raiding the gem vault,” Celestia interjected as she smiled warmly.

“It’s not like they were that hard to take down,” Kevin stated.

“We were just to glad to help,” Gwen added.

“However, I do have concerns if this means war between your two species,” Rook suggested.

“The Diamond Dogs are usually non-hostile, but their determination to get into the vault worries me that the leading ambassadors are planning something. This won’t make relations with them any easier,” Celestia explained as she held a hoof to her chin.

“What’s their infatuation with gems and diamonds?” Ben asked remembering encountering Vulkanus that one time he had Taydenite that Kevin forcefully absorbed so he had a supply to sell.

“Most likely they consider that their treasure,” Kevin added.

“More or less, that’s true. They are usually miners and work in the underground caves to find lost gems to bring back to their stash. Some even might make profit of it if they really wanted to,” Twilight explained.

“However, they would never dare consider coming to Canterlot in order to raid the vault. That is an act of aggression against the throne,” Luna noted.

“I’ll contact the ambassadors and see what lead to this decision. I don’t think they ordered a premeditated attack on the castle, but we cannot be too sure,” Celestia stated.

“Most likely someone else put them up to it. Probably spun some kind of story to make you all look bad or fed their lust for greed,” Ben suggested.

“Whatever the case, we still thank you four for helping out and you all as well, Princess Twilight, Applejack, Discord, Spike, Fluttershy, and Pinkie Pie. Once again, you’ve proven your dedication to Equestria with your service,” Celestia praised.

“All in a day’s work, Princess Celestia,” Twilight stated as she flapped her wings a little bit.

“In the meantime, I would like to invite Ben and his friends to stay at the castle for tonight and be our guests at dinner. I would like to know more about where they came from and about the Omnitrix Ben has around his hoof,” Celestia invited.

“We’re certainly taking that offer. You don’t mind, right, guys?” Ben asked as he turned to their new friends.

“It’s a once in a lifetime opportunity that the princess asks anyone to stay in the castle,” Applejack noted.

“We’ll see you all back in Ponyville soon enough. If you chat with Princess Celestia, she can tell you all about how Equestria was founded and all the amazing features of our world,” Twilight stated.

“Then I guess that settles it,” Rook concluded.

“It would be our honor to stay with you for the night, your Majesty,” Gwen stated.

Princess Luna smiled friendly at everyone, but something suddenly irked inside her as she felt a twinge of....jealously....jealous of her sister. This can’t be right....she grew out of that since she became reformed. She also felt a smidge of hatred as well and she had to shake her head loose of the thoughts.

“Are you alright, sister?” Celestia asked over to her occupied sister.

“Huh? Oh, yes, I'm quite fine. I became in my own head for a second there,” Luna replied honestly as Celestia nodded.

(Scene Break)

After the sun was settled by Celestia and Luna raised the moon to take over the night shift as well as listen to ponies in their dreams, Ben, Kevin, Gwen, and Rook all shared the same bedroom with the boys on one side and the girl with the alien on the other.

“What a weird first day this has been,” Gwen stated as she stared up at the ceiling.

“Saying that is the understatement of the century,” Kevin retorted as he placed his hooves behind his head.

“It’s really by some miracle we aren’t dead right now and that’s all thanks to Professor Paradox. I can’t shake that feeling of this world being on a path of war, though,” Ben stated.

“War is definitely not normal and the last one we got involved with wasn’t pretty,” Gwen reminded.

“That was pure pettiness and Argit made some serious coin off it,” Kevin muttered.

“I recall you helping him trade weapons to the red and blue sides,” Ben retorted over at his best friend.

“I’m partially reformed and you know this,” Kevin muttered as he turned on his side with his back facing Ben.

“I know this is worrisome especially after today’s events, but we better get some sleep and worry about this in the morning,” Rook stated.

“Rook’s right. A good sleep and rest are needed. We can sort out details when we are back in Ponyville,” Gwen added.

Kevin took that as the cue to get some shut eye as Rook and Gwen flipped the covers on their smaller pony bodies while Ben still had the thought in the back of his head. Paradox was a reason they were here, but what’s the purpose of it? What’s this state of war Equestria would be put through? He guesses he would find out sooner or later, but things happen so quickly for him and he needs his prep time so he can go hero when it’s necessary.
