As I'm walking back to the library, I hear the whispers of the ponies coming back to their homes.

"Look. He's the one who saved the town."

"Did you see what happened?"

"No, but I heard a few things. Explosions and metal hitting metal."

"I saw strange red beams flying through the sky above the buildings." Not everything they said was nice.

"Ugh, what is that thing"

"I think it's what saved the town from that other creature."

"Are you sure he wasn't the creature that attacked."

"Look at that thing, it's hideous." I hurried back to the library to avoid getting angry but I was already scowling. As I approached, a few of the ponies started wondering what I was going to do, since I'm too big to fit through the door. As I arrive by the library, I stop for effect… and then proceed to phase through the wall of the library. The gasps I heard from the ponies were priceless. As I step into the library, I see spike sitting by one corner looking worried. He sees me and then screams like a girl.

"AAH! Oh. Phew. It's just you Seth. Wait. What happened?! I-I-I heard booms and-and- What happened?" He asks, panicked.

"Don't worry Spike. Everything's fine now. Bad guy's taken care of and in the princesses custody. Now, if you don't mind, I have a duel to prepare for. You wouldn't happen to have a massive mirror I could use, do you?" I say calmly before my expression becomes mischievous.

"Oh thank- wait, duel? What duel? You said the princesses got the bad guy? And why do you need a mirror?" Spike asks me.

"My duel with Princess Luna tomorrow, yes they did and I haven't properly looked at this body yet." I answer.

"Oh."

"Somepony wanted a mirror?" Screwball says, appearing with a mirror that stretches to the ceiling.

"Gah! Where did you come from?!" Spike shouts.

"I heard Seth needed a mirror so I got one. Here you go!" Screwball says, pushing the mirror in my direction. I stop the mirror and turn it to look at myself. From top to bottom I see:
I'm wearing U. Big Chills cloak over my head and body, it bearing U. Cannonbolts colour scheme as well as the studs U. Cannonbolt has when he isn't in sphere form.
My face is mostly that of U. Humungasuar, with a few differences. Those being, four extra eyes on the lower half of my forehead and in-between those eyes rests one of U. Echo Echos speakers.
On the sides of my head where my ears would be, there is also a Echo Echo speaker on both sides.
My chin seems to have a line passing through the center of it. I stare at it for a second, trying to remember where it is from when I remember how U. Spidermonkey shoots his webbing. I think about trying to open my mouth in the same way and succeed, gaining a pair of disgusted groans from my audience.

"Ewww. Is your mouth meant to do that?" Spike asks me. I 'close' my chin and answer.

"I think so."

"Why?" Screwball asks me. "Is it for intimation? Because it works. That is really scary."

"Possibly. But it's more for this." I say, opening my chin and webbing Screwballs feet to the ground.

"Huugh. Sticky." She says.

"Of course it's sticky, it's a web." I say.

"Web? Like a spider?" Spike asks me.

"Yeah. Like a spider." I say, resuming looking myself over.
My skin is the colour of U. Swampfires wooden body parts, being a muddy gray.
I open my wings to look at the rest of my body, causing Spike and Screwball to ooh at me.

"Wooow. No wonder your wearing that cloak. It's actually your wings! Hey, where'd your studs go?" Spike says and asks.

"Yeah. What he said." Screwball says. I fold my wings slightly so I can see the outsides, and see the studs on my wings have vanished. I fold my wings completely and the studs emerge from the shoulder, wrist and back areas.
Huh. Guess the studs sink away when I unfold my wings. Must be so I can fly better. I think to myself. I unfold my wings again, eliciting another ooh from my spectators, and continue looking at myself. I see:
On my shoulders and chest, there are more Echo speakers, one on the side of each shoulder and one by the bottom of both my pecks.
Looking further down, I see what look like spider legs stuck to the sides of my stomach coming from my back. I try and get a feel for them, causing me to extend them slightly. Spike and Screwball see this and do a take.

"What are those?" Spike asks. "Are those spider leg- Ooooh, is that why you can spit webs?" Screwball looks like she has drawn the same conclusion as Spike.

"The legs and spitting are both abilities of one of my parts. If your confused, I will explain. My body is made up of multiple different beings put together. Each one of those beings are one of my parts. One…" I stop as I hear writing. I look to Screwball and see she is writing on a note pad. "Screwball, what are you doing?" I ask her.

"Writing this down for Twilight." She answers.

"Oh. Continue." I say as I return my attention to Spike. "As I was saying, one of my parts are called Ultimate Spidermonkey. It gives me the ability of a monkey and a spider combined and enhanced, hence, Ultimate Spidermonkey." Spike just stares at me in wonder.

"Wooow. How many parts do you have?" Spike asks dreamily.

"If I'm right? In this form? Six. Swampfire, Spidermonkey, Big Chill, Humungousaur, Cannonbolt and Echo Echo. By the way, each ones name has a ultimate on the front." I explain to the young dragon.

"Whoa. Wait, in this form? What does that mean?" Spike inquires.

"I'm pretty sure I can change my form, but I haven't tested it yet." I respond.

"Could you try it now?" Spike asks hopefully.

"I… could… But just to be safe, go stand over there." I say, pointing at one wall. Spike heeds my instruction and moves to a far wall, Screwball following him. Once they reach their safe spot I focus on my powers. Thinking about what I read in the note from the Genie, I focus on a attribute of one of the other ultimate aliens I've seen. Almost three seconds later, two reddish tubes have sprouted from my back, their ends expanded outward into the shape of strange funnels. When I'm finished, it looks like I have grown two pipes from my back, both emitting cold puffs of air.

"Alright. It worked." I say.

"W-what did you do?" Spike asks. " And what are those?"

"These," I say pointing to my new appendages. "Are the secondary mouths of U. Arctigauna and they can do this." I respond, ending my sentence by freezing one window shut. "Ta-da~"

"Cool. Literally." Screwball says then snaps her fingers, causing the ice to disappear and confusing Spike. I retract my extra appendages, as well as fold my wings and continue my self inspection to see:
On my arms are the blue pods I saw during my fight with Aggregor. I decide to risk it and pull one off. It comes off painlessly. But my experiment has spooked my audience again.

"Ah! What are you doing?! You can't just… oh wait, don't tell me, it's meant to do that." Spike says.

"Yep."

"Oh. What's it do?" Spike asks me.

"Explode. I think. Might be able to do more than that."

"Explode?! Awesome! Wait, DON'T SET IT OFF IN THE LIBRARY!" Spike shouts.

"Don't worry, I won't." I say, successfully replacing the pod in my upper fore arm.
Glad I can do that. I think to myself. I look further down my arms to see my four fingered hands with metal plating for knuckles along with the speakers on the back of my hand and palm. I focus on doing what I did in my recent fight and change my hands into launchers again.

"Whooaa. What are those?" Spike inquires.

"They're missile launchers." I say calmly.

"Missile launchers?! COOL!" Screwball shouts.

"What's a missile launcher?" Spike asks.

"A mid to long range explosive weapon." I say, changing my hands back.

"Oh. Please don't set off any explosions in the library, I'd have to clean it up." Spike says.

"Sure." I respond. I look in the mirror again and see I have U. Humungousaurs stumpy legs. Down my shins, there are a pair of Echo speakers on each leg. I turn so my side is facing the mirror. I see that instead of the turtle like shell that U. Humungousaur has in his back, I have a ridge along my spine that my wings are attached to, like Big Chill. My spider legs are also attached to the lower part of this ridge. I also see I have U. Humungousaurs mace ended tail. "Awesome." I comment.

"Ya think?" Screwball says jokingly.

"Well, I know what this body looks like now. Thanks for the mirror, Screwball." I say. Seth.
Now, where would a good training area be. I think to myself.
Hmmmm.

"Hey Screwball-" My question is interrupted by the door opening.

"Uuuugh. That took forever." I hear Rainbow say.

"It took an hour and a half." Twilight replies. "And besides, we needed to make sure he was contained."

"Yeah, I get that but still… Oh hi Seth, what are you doing here?" Rainbow says, her voice trailing off as she sees me and she asks a question, nervously looking at her shocked friends that have walked in the door. I am confused for a second before I realize I haven't properly met any of the main six except Twilight, Rainbow and Pinkie.

"Oh. Hi everypo-"

"AAAAAAAHHH! WHAT IS THAT?!" Rarity screams as Applejack gets into a defensive position, Fluttershy hiding behind her. Sensing the brewing confrontation, Twilight teleports in between her friends and me

"Calm down everypony! He's the one who saved the town." Twilight says to her scared friends.

"Yeah, don't worry. He's cool." Rainbow adds, calmly walking up to me.

"He's cool? What do ya mean? He's cool. He looks like a monster!" Applejack yells.

"Hey! He isn't a monster, he's awesome." Rainbow defends.

"What? The heck you talking about, look at him! He looks like something the Everfree spat out." Applejack yells, me starting to get annoyed at being insulted.

"I was found in the Whitetail woods, thank you very much." I say to the farm mare, eyes narrowed.

"You stay outa this!" Applejack shouts.

"Stay outa this?! You are Literally insulting me To My Face!" I say, taking a step closer in anger.

"Whoa whoa. We shouldn't fight-" Twilight tries to say but gets interrupted by Applejack.

"Yeah? What ya gonna do about it?!" Applejack challenges, also taking a step forwards.

"I will drop you in the Everfree if you don't shut up!" I yell.

"Alright. That's it!" Applejack says, charging me against the behest of her friends. I respond by turning into a ball, letting her harmlessly hit my now formed armour.

"Ow! You cheating bucker! What was that?!" Applejack yells. I unroll myself and stare her down.

"I can turn into a ball."

"That all?" Applejack says, going for another punch with her other hand.

"No." I respond, letting the mare pass through me. She trips from over doing her punch and falls on her face. She gets up and growls at me.

"That's ENOUGH!" Twilight yells, flaring her magic. "Applejack, listen! He isn't a monster. And Seth, stop riling her up!" Twilight says.

"Sorry Twilight." I say, sitting down.

"Yeah, sorry Twi." Applejack says but her eyes are still on me.

"So, what are you?" Rarity asks me.

"That's… not an easy question to answer. Originally, are you writing this down?" I suddenly say, looking to Screwball. She holds up a pen and paper pad in response. "Good. Anyway, originally I was a normal human being, don't ask what that is, then I buy I replica from a stall, next thing I know, I'm waking up in the Whitetail woods as a Osmosian hybrid." Seth.

"Okaaay. That doesn't really answer my question. And who are you?" Rarity asks Screwball.

"Oh. I'm Screwball, daughter of Discord." Screwball says, casually floating up to sit in the air.
A few seconds of dead silence pass before…

"WHAT?!?!" Everypony shouts. They start clambering about but I stop them.

"Could you all just shut up! She's not a threat."

"Not a threat?! How is she not a threat?! She's- wait." She suddenly stops and looks to Screwball.
"HOW DID DISCORD HAVE A DAUGHTER?!" Twilight asks incredulously.

"Chaos." Screwball answers simply.

"Ugh. Spike!" Twilight says.

"Twilight, no. You can't contact Celestia. She'll imprison her." I say.

"What do you expect me to do? Let her roam around causing chaos like Discord?" Twilight retorts.

"I'm right here and besides, I don't do that. I barely use my powers." Screwball, now on the ground, says.

"Really? I'll still need to tell the princesses. You can't be left on your own." Twilight says to the chaotic mare.

"Then I'll watch her." I say.

"What? Seth, no. You can't." Twilight says.

"Why not?" Screwball asks. "He's definitely strong enough to protect and keep an eye on me.

"Exactly. As of this moment, Screwball is my responsibility." I declare firmly. Seth.
What the? My thoughts are interrupted when Twilight says.

"Fine. But that means it's your job to make sure Screwball doesn't cause trouble. Understood?" Twilight asks me.

"Clear as crystal." I respond.

"Alright. By the way. That stallion you defeated has been taken to Canterlot." Twilight says to me.

"Thanks but he's not a stallion, he's a Osmosian." I say.

"Wait. Aren't you an Osmoian- Osian- that too." Twilight says, struggling to pronounce the name.

"I was turned into one, yes." I respond.

"I knew it!" Applejack shouts, running at me again. I just web her feet to the ground, causing her to fall on her face again. "Eww. What is this stuff."

"A web." Spike replies for me.

"A web? What, is he part spider or something?" Applejack asks. I extend my spider legs and place them on the ground but I don't lift myself up because I'm sitting on the ground.

"Yes." I reply, folding my legs back under my cloak. Applejack just looks disgusted.

"Since when do you have those?" Twilight asks me.

"Since I became this. I just didn't know about them before but I recently got a good look at myself." I reply, winking at Screwball. She smiles at me. I yawn all of a sudden, bringing my hand over my mouth.

"Oh wow. I didn't realize I was this tired. Hey Twilight, would I be able to sleep here? I don't have anywhere I can go." I ask the purple unicorn.

"Oh. Sure Seth. You must be tired. And, *Yawn* I think I am too." Twilight says yawning in the middle of her sentence and turning towards the stairs to her room. "Goodnight everypony!"

"Goodnight Twilight!" Everyone calls, head to their own destinations, with spike head to his bed and Screwball snapping up a sleeping bag.

"Hey Screwball." I ask her as she climbs into her sleeping bag next to me.

"Yeah?"

"Could make a me sized sleeping bag too please?" I ask her.

"Sure!" She says, poofing in another sleeping bag.

"Thanks." I say, phasing into my new sleeping bag. "Goodnight Screwball."

"Goodnight Seth."

Seth. Seth. Seth.Seth. Seth. Seth.Seth. Seth. Seth.SETH!

"Seth, wake up."

"ALRIGHT! I'M UP!" I shout.

"AH! Seth. What was that for?" Twilight asks me.

"Oh. Sorry. I kept hearing my name-" Seth.

"Bwuh. There it is again." I say, looking for who is calling me.

"What's going on?" Screwball asks as she wakes up next to me.

"What are you doing here?" Twilight asks Screwball.

"I'm supposed to be being watched by Seth, aren't I?" Screwball responds. "Anyway, Seth what are you talking about?"

"Yeah, are you alright Seth?" Twilight asks me. I try to respond but I get interrupted.
Seth. I hear again, this time sounding like it's coming from behind me.

"I… I think something is calling me." I say.

"Calling you? What do you mean-" Twilight gets interrupted as I phase out of the library. Twilight and Screwball teleport out as well.

"Seth, wait." Twilight says but I ignore her.
Seth.
Something or someone is definitely calling me. Seth.
Wait. Is that a woman's voice? Seth. That is definitely a woman's voice.

"I'm going to go check it out." I say to the mares behind me.

"I'm coming too." Screwball says, jumping on my back.

"Alright, hang on." I tell her. "Twilight."

"Yeah?"

"Tell princess Luna we'll have to postpone our duel until I figure this out."

"Alright. Be careful."

"I will." I say, unfolding my wings and taking to the air, surprising a few ponies who were looking my way.
A minute of following the voice later, she has become much clearer, to the point that I feel like I recognize her. I notice I am flying towards the Everfree.
Please don't tell me her voice is coming from there. I think. As I am flying I see a pink light shining from the inside the forest. I can feel that is the source.
Darn it.

"Is that it?" Screwball asks me.

"I think so." I reply. "Going in for landing." I say, angling my wings to descend. Ten seconds later, me and Screwball land in the forest, a few meters away from the light. From here, we can hear crying. The voice is also louder than ever. As we approach the light, I can see a silhouette of a woman sitting in the center of the light. She looks up suddenly and sees us, standing into a defensive stance and canceling the light. I see her whole body is a seamless dark purple, with her hair being a glowing pink.
An Anodite? Wow.

"Who're you?" She asks in a frightened echoing voice, her hands now glowing.

"Don't worry. We won't hurt you." I tell her.

"How do I know I can trust you?" She asks us. Hearing her voice so clearly, even with the echo, I can recognize it.
No way. Deciding to test if I'm right, I say something I hope she recognises.

"I am now more powerful than any of the seven deadly sins." I say with a serious look on my face. She gasps.

"Is it really a good idea to threa-" Screwball tries to say.

"SETH! YOUR HERE TOO!" I hear as I get tackle hugged.

"Bella?! It is you! Alright!" I shout as I hug my friend back. Screwball just looks at us, confused.

"Uhh… what's going on here? Seth do you know her?" Bella now looks at my friend and charge, only now seeming to notice what she is.

"What the?" She says, her voice not echoing as much now, but before she can say anything else I put my hand on her shoulder, drawing her eyes, and subtly shake my head. I hug her close again.

"Wow. Am I glad to see you. Except it seems I'm not seeing you-you." I say to make conversation.

"Your one to talk, look at you! What even happened?" Bella asks me.

"You know ultimate Kevin? Imagine that with the ultimate aliens."

"Wow. That's awesome."

"Your not the only one to say that.

"Excuse me! Can I have an explanation. Who are you, how do you know Seth and what did he say to you?". Screwball asks Bella.

"Allow me." I say. "Screwball. This, is Bella. She is my best friend. And what I said before is a reference that she understands."

"Oh." Screwy says. "Wait, is she from the same dimension as you?"

"Yes, she is." I say before I realize a crucial detail. "Wait. Did you meet the Genie too?"

"You mean the guy dressed as the Genie who sold me a wig?" Bella responds.

"That's the one. Wait. Why did you buy a wig?" I ask.

"I was looking for you and the guy said he'd tell me where you were if I bought something so I bought this." Bella says, pointing to her hair.

"Huh. Could have been worse. You could have ended up like me." I joke.

"Yeah." She says with a smile, before frowning. "Do you think we can change back? Or even go back?" She asks me. I just frown too.

"I don't know. I've only been here a day. But you might be able to change back, Gwen could."

"Gwen had a human body, I don't think I do." Bella tells me.

"Just try." I ask of her. She smiles.

"Alright." She says and closes her eyes. A few seconds later her face scrunches up before a wave of pink energy passes over her and I see my childhood friend standing before me.

"Told you." I say. She punches me in the side in mock retaliation.

"Wow. My second day here and already things have grown weird." I say.

Kudos if you can find the first Seth.
And sorry for the longer wait. I was feeling a little slow.
