The girls had grouped together in the middle of town, Applejack had explained their current dilemma. Twilight rubbed a hoof against her chin, "and Applejack you are sure when it changed it stood in a bipedal position with weird clothing and fingers?" The princess asked the earth pony, Applejack nodding.

"Ooooo I wonder if it likes parties! I like parties!" Pinkie Pie said as Rarity sighed, "Pinkie darling we know you do."

Rainbow Dash rubbed her hooves together, "well it has been a while since a good monster attack!" She said grinning widely as she started to hover over the group, Twilight smacked her face with her own hoof. "Girls we just need to find it, who knows where it could be now?" She asked them.

From Applejack's description it sounded like a human...but she had to be sure herself, Fluttershy spoke up. "W-well I may have an idea where it could be...maybe s-still in town? Applejack did say it had a weird green hourglass collar around its neck...when it was a wolf.."

Twilight looked at her, "good idea! We either look for the hourglass or anything else that has a weird physcial appearance similar to a bipedal stance."

The girls thought for a moment before nodding, "split up it couldn't have gone far if that's the case." Twilight said as the gang all split off into different directions.

Nick was laying on is back looking at the Omnitrix, "dude this is so awesome! Aside from getting stuck in a 9 year old girls dream this Omnitrix is awesome!!" He said as he looked through the list of aliens, clicking the top it sliding back and he slammed his hand down on the dial. Instead of his choice of Four Arms his bones stretched out as fur grew along him. Spike like weapons popping out of the top of his hands along with claws growing from his finger nails.

He blinked a bit before looking at his hands, "LET ME TELL YOU SOMETHING OMNITRIX! RATH DID NOT CHOOSE RATH! RATH CHOSE FOUR ARMS!" He shouted at the device, Nick seemingly was near the entrance of the Everfree Forest as he looked around growling to himself.

"While Rath is pretty cool Rath chose Four Arms!" He stated as he growled a bit before shaking his head. Looking back at the town he then said, "Rath wonders if their still looking for Rath." He said as he heard the beeping of the Omnitrix shifting back to his human form.

"God Ben is right that is inconsistent." Nick said to himself as he then looked at his watch, sliding his fingers up a bit to look through them more, the sound of hooves making him jump a bit as he quickly whipped around, his hand over the popped up dial.

His eyes fell upon what looked like a Pegasus, Unicorn or both? His eyebrow raising as he narrowed his eyes, “Wait!” she shouted holding her hooves up defensively.

Nick narrowed his eyes, “who are you? You're the first pers- pony...To not immediately attack me!”

“You're a human right?” she asked as Nick's eyes widened a bit, “well. Yeah. I am human.” He replied.

“What are you doing here? How did you even get here?” She asked Nick.

“No no. You're gonna answer my questions first, where the hell am I? What are you? Who are you? And how do you know what a human is?” He responded taking charge of the situation.

She sighed rubbing both her hooves against her eyes and letting them slide back down, “my name is Twilight Sparkle, where you are right now is Ponyville in a place called Equestria, I am one of the 4 princesses that rule this land with the power of friendship and kindness. As for how I know what a human is? I went to the human world on a mission assigned by my fellow princesses.”

Nick blinked a bit, “well I think you're the most friendly pony I've seen. An orange one with a cowboy hat attacked me.” He said moving his hand away from the Omnitrix the dial being pushed back down and the top popping back over it automatically.

Twilight narrowed her eyes his looking at him, "now could you answer my questions please?"

"Well...I don't know what I'm doing here. And as to how I got here?" He raised his right arm showing the Omnitrix to her, "this watch. It sent me here after I bought it from a merchant in a convention." He said as he chuckled to himself, Twilight tilted her head.

"What's so funny?"

"Ah nothing I just realized how insane this situation is!" He said as he leaned his head back laughing harder as he rubbed his eyes before shaking his head. A purple aura surrounding his arm as he was pulled forward toward Twilight.

"What is it? I don't believe I've ever seen a watch like this before." She said curiously examining the watch.

"It's called the Omnitrix. It allows me to turn into various alien forms, while also being nice and snug attached to my wrist." He said feeling the force of her magic trying to pull off the device.

She sighed relinquishing her grip on his arm with her magic, Nick shook his arm a bit as he put his hands in his jacket pockets. "You think your friends will not try to kill me again if you talk to them?" He asked her, Twilight gave a sheepish smile. "I hope so."

"Well that's really assuring." He replied. He then sighed, "names Nick by the way." He said as Twilight nodded smiling at the human.

"So what? We headed back into town?" He asked looking at her his Omnitrix flashing yellow, "Uncatalogued DNA detected." It said a yellow beam scanning over Twilight, "amazing..." She said looking at the watch as it finished turning back its bright green.

"Yeah, it scans and copies any new species so I can transform into them." He said as he looked at her, grinning a bit at her confused face.

The alicorn just shook her head to get out of her trance like state at the information, "we should probably head back to the town." She simply replied as Nick nodded, "aye. That should be fun."

A few minutes had passed after Nick and Twilight's initial run in, the time giving Nick to fool around with his Omnitrix out of curiosity. 'Nicholas Devin Taylor, messing around with the most powerful piece of technology in the known universe! God.' He thought to himself a smile on his face.

"Bloxx, Heatblast, Swampfire, Four Arms, Frakenstrike, Brainstrom, Greymatter. Jesus Christ there's more aliens in here then I thought!" He said as he looked at the alicorn, the two hadn't talked since their walk back to Ponyville.

The only form of talking was coming from Nick either talking to himself or talking about the watch.

"There's the vermin!" A familiar voice filled Nick's ears as in the blink of an eye something slammed into his back making him fall forward and roll along the ground as he groaned a bit. Looking up he saw a rainbow blur fly into the air and stop as a pegasus was shown floating with her hooves on her waist.

Nick stood up as he felt the all to familiar orange pony slam her head into his chest, the force actually knocking flat on his ass. "Ok that's it!" he shouted as he jumped up scrolling through his list of aliens before pushing down the pad as the dial popped up and he slammed his hand down on it.

His skeleton growing as his hair disappeared and a reptilian like skin grew along his body as his size increased. A green belt wrapped around his chest with the Omnitrix symbol on the middle of it, "Humungousaur? Oh hell yeah!" He said as he felt another strike from Rainbow Dash shaking his head as he looked at her, seeing her come back another time he dodged and quickly grabbed her tail throwing her into the ground.

Pinkie Pie's eyes widened, "Dashie don't worry I got him!" Pinkie said as a wide smile spread across her face, then pulling out her Party Cannon out of nowhere she fired a round.

A cake hitting Nick's left eye as he roared trying to get it out of his eye, it stinging from the fact cake was in his eye.

"Girls stop!" Twilight shouted Fluttershy shivering standing beside her, Rarity using her magic to surround Nick's legs with a blue aura managing to trip him and make him fall on his back.

Rainbow Dash recovering and dashing forward snatching Applejack's lasso and flying toward Nick wrapping him in it.

"U-um girls I would listen to T-" Fluttershy was cut off as Pinkie Pie shot another cake at Nick who was laying on his back trapped in the lasso. It hitting under his chin as he growled at them.

"GIRLS STOP!" Twilight shouted all of them pausing as they looked at her, "listen. This thing, Nick. He isn't a changeling! He's one of those humans I was telling you girls about!"

"But then what the buck is he now?! Only changelings transform like that!" Rainbow Dash replied.

"If you'd let me go I could show you how." Nick said looking up.

"No way buddy! We finally got you!" Rainbow Dash said narrowing her eyes getting face to face with Nick, Twilight gave Rainbow Dash a look. "Rainbow Dash. NOW!" She said asserting herself as the rainbow maned mare growled and flew back ready to take the lasso off.

Nick simply sitting up and growing, increasing his size easily snapping out of the rope. The ponies jumping slightly especially Dash and Applejack.

"W-why didn't you just do that before?" Rainbow Dash asked Nick.

Nick smacking the Omnitrix on his chest reverting to his normal form, "because I wanted to see if you'd let me out, or cool your hot head off. And because I wanted to see your faces." Nick said grinning widely letting out a small chuckle.

Applejack grumbling a bit, "girls this is ridiculous!" Twilight stated.

"Well he did slam Dashie into the ground the big meanie." Pinkie Pie stated as she looked up at Nick.

"Only because she smacked me in the face full speed." Nick responded to the bubbly pink mares statement.

Rarity rubbed her chin looking at Nick, "now darling you where going to explain how you transform? So we know you're not a changeling?" She asked raising an eyebrow. "Then after that we have to talk about your wardrobe, those clothes are horrendous!"

Nick looked at her, "hey I like my clothes. And as for how I transform?" He pulled his sleeve down showing the Omnitrix resting on his wrist. "This is the Omnitrix, a piece of alien tech that allows me to turn into I believe 99 or more different aliens. But trust me there are a hell of a lot more forms in here, millions." He explained as he used touched the faceplate of the watch, sliding it up scrolling through the holographic list before pushing down on it, it sliding back as Nick slammed his hand down on the dial.

His body seemingly shrinking down, his hair extending and changing a pure black. Green fur growing along his body as his fingers shrunk down hooves forming, a tail growing as his eyes turned a bright green the transformation complete as he stood up straight looking at them.

The Mane Six staring at him as they examined him, the Omnitrix logo on his flank. "I got this one from the orange ponies DNA." He said.

"Darling I like your mane! It looks amazing!" Rarity complimented as Nick chuckled a bit.

"And you're sure you aren't a changeling?" Rainbow asked him, "YES!" He and Twilight shouted in unison.

Pinkie Pie bounced around Nick, "this is awesome! We gotta throw a party for you Nick! Don't worry I won't forget I'm great with names!" The pink mare said smiling widely.

Applejack rubbed her jaw a bit before shaking her head adjusting her hat, "well...I suppose if you got the trust of Twi, then I guess I'll give you a second chance."

"Agreed." Rarity said as Pinkie stopped standing in a bipedal stance scooping Nick up in a big hug. "Yes of course!" She said with a wide smile.

Fluttershy looking at Nick, looking at him shyly for a bit before giving him a soft cute smile. Nick smiling back as he looked at Rainbow Dash.

The mare looking back at him, "yeah whatever.. she grumbled.

Nick smiled as he heard the beeping of the Omnitrix it reverting him to his human form as he stretched a bit, "thanks guys I guess."

"If you want you could stay at my house." Twilight said smiling at Nick, the human nodding. "That would be nice." He said smiling back at her.

Rarity's eyes then sparkle, "I could make so many custom designs for you! YOU HAVE TO COME OVER TOMORROW AFTERNOON!" She said excited.

"I'd be fine with that. But for now. I'd like to just get some shut eye." He said letting out a small chuckle.

The girls nodding as they lead him back to Ponyville.
