I decided to retcon Dimentio713's origin story to what you see right now. This all takes place before the Mechamentio arc started to pick up.

Let me tell you a story, a story about a child who was destined for greatness… The trials in his life was difficult, the people he met helped to become. This child was neither a villain nor was he a hero, he was a simple child who fought for the truth. A child who fought for what was right. Of course, he wasn't REALLY a child, he was actually 13 years old, just now in his teenage years. It all started on an April 18.

A young boy walked in a city, noticeably, the sky was green, and he was Filipino. He had a blue Raccoon Mario t-shirt, a grin on his face, denim pants, oval glasses, and simple running shoes, but that was not his only trait about him, he had a mask on him. The mask was black on one side, and white on the other. It seemed to be grinning with its bright yellow eyes. He also had a watch that told the time, like all watches do and was apparently listening to his iPod.

I don't care what you're thinking as you turn to me

'Cause what I have in my two hands is enough to set me free (set me free)

I can fight the feelin' to resist it over time

But when it's just too much to take you sneak up from behind

Is it me? You say, you're looking for?

Let me show you who I am and what I'm here for here for

Heaaay!

Try to reach inside of me!

Try to take my energy!

Let me show you just what I'm made of

Simple curiosity, trying to take a bite of me

Let me show you just what I'm made of now...

People looked at him, they all either had a cloak over them, or a mask on their person.

"As per usual, I made a scene." He said to himself, "Honestly, I'm probably the DUMBEST person I've ever met…"

He looked at the crowd, embarrassed, "Sorry…" He said, but everybody left, going on with their lives.

He sighed, "Why'd Dimentio-sensei ask ME of all people to go on a mission, he didn't specify and he DIDN'T make sense…" The boy's name was Dimentio713, our protagonist, and a deadpan snarker, at least when he was thinking…and a pretty jolly person to be around. I know, he had a bit contradictory personality…but what do you expect when you lived your whole life in a different dimension.

He was a student of Dimentio-sensei, not really one of the smartest, not the strongest, but he was pretty positive…despite his snarky nature. His sarcasm only came when something stupid happens… Either to himself, or to something happening related to technology. He's what one would call, a bit of a critic. So he walked, he was needed somewhere and gosh darn it, he'll be there! He dashed to where he was needed, where we will go to… Soon.

Now there was another student of Dimentio-sensei who admittedly looked goth and female. Of course, she would've been goth if she had black eye-liner, and pretty much looked like she hated life. Now she didn't hate life persay, she only really, really didn't like one person… Only a bit… His name? Dimentio713. She didn't like how annoying he was, but of course, she couldn't do anything about it. Her name was Dimentia713 and, like Dimentio, she was Filipino, with her black shirt with a Poison Mushroom which showed her midriff (thankfully not much), a pink streak in her hair, an annoyed look on her face, and long pink skirt and she got up. She looked at her mask and sighed as she looked at her left hand, right now it was gloved, now the reason it is gloved was because… Well, you'll find out later! Often times, she didn't have to wear the glove, but today she had to, it was a bit inconvenient, but she didn't let it worry her.

She walked off, looking into the distance when she remembered something important,"Need to go to Dimentio-sensei's office soon." She told herself, "He needs me to go on a mission… When was the last time I went on a mission, I just remember that I failed, no I didn't fail, it was Dimentio713…but he acted pretty cute…" She then came to realization, "WHAT THE HECK! WHAT AM I THINKING! …Ay naku…" Dimentia ran off to go to Dimentio-sensei's building.

A black-cloaked boy looked around his black hair rustling in the wind, "Alright… Time to go to Master Dimentio's office." He said to himself, "Hey… Will my scene end quickly? Cause I didn't have time to introduce myself…"

A few minutes passed as the boy looked around, "Oh."

He put up his hood, now the boy had his face covered by the cloak with only glasses visible, his hands were covered in black, his name was Fawful212 and he waited for a few minutes, "Is it d-"

So Fawful212 was interrupted, don't worry, he'll be in the plot more later on…but not right now. Anyways, where were we? Oh yes, where Dimentio713, Dimentia713, and Fawful212 were all headed toward right now. Clearly, we will expect something some forced comedic interactions… What with Dimentia disliking Dimentio, Fawful being a normal kid, and Dimentio snarking…in his head.

Dimentio put on his mask and fire started to appear around him. Inside the fire, there he was…on fire. Yeah, him not burning was kinda a shock…the only thing that wasn't on fire was his mask, the mask's eyes were closed and suddenly it opened. A firey tail appeared behind him and the fire faded away, showing a monkey with a mask…with its tail on fire. Gee, fire seems to be a HUGE theme going for Dimentio713… Anyways, with this form he could run fast… I guess it's because fire equals fast, I'm not sure, but he also had fire abilities…and magic.

"Yay, I became a freak of nature!" Dimentio said in his head, "If I ever start crossdressing... I'll rethink my life."

Actually, he kind of liked this form, he just didn't enjoy it often. The transformation isn't really fun persay, in fact it was kinda hot there. Let's just say the first time it happened… "Wait… When WAS the first time it happened?" Dimentio pondered.

It was clear that Dimentio did not remember much of his childhood… It's not that he was bad at remembering things, but he was, but because it seemed to be a closed-off memory, a memory that could potentially destroy him…or fix him.

So yeah, he just ran… Was he a coward, far from it! In fact, he was reckless...

"MY HOMEWORK!" "MY SPEELN!" "MY KNEE!" "Hello I'm the Nostalgia Crit- WHAT THE HECK!" "I LOVE YOU DIMENTIO!"

"SHUT UP!" Dimentio exclaimed annoyed, "Who the heck are you anyways!" Dimentio said, no doubt confused.

The voice that loved him was silent and Dimentio blinked, "I'm leaving now..." He ran again. So Dimentio watched the area go all around him, loops and turns was in his way, but he didn't care, it was fun! He noticed a sharp turn coming straight at him, he put his hand on the ground started to move his feet...as if he was drifting.

"Kids," Dimentio said, breaking the fourth wall, "Don't try this at home."

He started to run backwards and relax, "Ah, life is good... Life is- Oof!" Dimentio got up and started to dust himself, "Geez, I'm really sor- ...Oh, it's you Dimentia, how's life treating ya?"

"I've been better..." Dimentia said, looking at Dimentio, "Until you came along that is."

"Does Little Miss Tsundere have a crush on me?" Dimentio teased the goth-looking girl.

"No." Dimentia said, deadpan, "Look, I wanna go inside. Now."

Dimentio grinned, wanting to be friendly with her, "Dimentia, I know that you have SOME problems, but still, you need to open up!"

"I'll open up when I feel like it." Dimentia retorted, "I need to get into this building, so please leave."

Dimentio started to smirk, "Actually, I need to go inside too!"

"You know... She's really annoying at times, honestly, I'm just trying to be friends with her." Dimentio thought.

"I can hear you." Dimentia thought back, "You forgot I'm psychic."

"A Psychic Tsundere." Dimentio had a smirk on him, "What are ya, goth too?"

"I'm not Goth! I'm just a Psychic Tsundere!" Dimentia exclaimed, now blushing, "...Let's just go inside."

Fawful212 came and looked at the building, "Thank goodness I'm not late..."

There was a lot of commotion going now. Dimentio looked around, Dimentia walking ahead of him, "Hey, wait up!" the young boy said, "Geez, how annoying..." A figure bumped into him, "Holy pineapple!" He exclaimed.

"My goodness! I'm SO sorry... I'm kinda clumsy." He said, "Name's Fawful212."

"Dimentio713." Dimentio said, "I take it that you're in Master Fawful's section."

"Yup!" His glasses seemed to be sparkling, "I need to get to Master Dimentio's office right now."

"Alright, let's go to Dimentio-sensei then." Dimentio said with a grin, "So why do you cover your face with a hood?"

"..." Fawful was silent.

"Oh..." Dimentio said, looking at his acquaintance, "I take it you don't like talking about it."

"Yeah..." Fawful looked at Dimentio, "Hey, you still have your mask."

Dimentio laughed, "Oh!" He took off the mask, becoming human once more, "So..."

"Huh... You look familiar..." Fawful said, "That face..."

"Really? Well, it doesn't matter right now." Dimentio said, "Let's just go to Dimentio-sensei, shall we?"

Fawful nodded, "Alright."

Dimentio-sensei started to walk around, his face looking up, "It's been awhile since...HE had my body..." He thought, "He hasn't shown up for awhile... I hope it stays that way..."

"DIMENTIO-SENSEI!" Dimentia yelled, "You called?"

Dimentio-sensei smiled, "Good to see you Dimentia. Wait, your partners will be arriving."

"...Would you believe that sensei went off easy on me?" Dimentio's voice said.

"Didn't know he would do that... Master Fawful would be 'Fawful212 you must be having attention with moreness'!"

Dimentia coughed as Fawful and Dimentio looked at her, "Oh! Dimentia713!" Dimentio said, grinning once more, "Didn't expect to see you here!"

"Wait... I have to be with THAT dumbcake!" Dimentia exclaimed.

"Were you referring to me?" Fawful asked her.

"Nah, you're cool." Dimentia said, waving her arm noting that she didn't care about Fawful212, "It's him I'm worried about." She said, pointing at Dimentio.

Dimentio-sensei sighed, "Look you three, I'm sending you on a mission so that you three can get along."

Dimentia sighed, "Really? Great..."

Dimentio-sensei looked at the three, "Listen to me, alright? I really want you to get along. Your mission is this: Meet new people, get along, and more importantly, fight off what ever attempts to harm you or your friends."

Dimentio nodded, "You got it!" Dimentio looked at Dimentia and Fawful, "You guys ready?"

"No." Dimentia deadpanned, "I'm far from that."

"I'll get ready the teleporter." Dimentio-sensei said, "Master Fawful?"

Master Fawful came in, "You had calling of me Dimentio-sensei?"

"Be sure to finish up the project. You three will have to live with each other for awhile."

"Joy..." Dimentia said, sarcasm dripping in her voice.

MONTAGE TIME!

Dimentio was seen eating ice cream and sat down, "Time for some daily reviews of random stuff."

"You review stuff?" Dimentia snarked, "How moronic."

"Oh shut up!" Dimentio retorted, "I'm watching Naruto! ...Clearly orange suited ninjas are the BEST way to be hidden!" He said, rolling his eyes.

"Alright..." Fawful was seen screwing something in, "PLEASE WORK!"

It blew up in his face, "...Of all the possible things, this is THE WORST POSSIBLE THING!"

Dimentio looked in the door, "Hey! You have black hair!" He said.

Fawful's glasses looked annoyed as he put his hood back on, "Suddenly, I don't look up to you anymore."

Dimentia looked at her mask and put it on, pink energy surrounded her and she looked like a ballerina with things that looked like red hairpins. The mask covered her face and she looked around, "Alright..." She focused all her energy into a ball and blew it up, "Looks good." She took off her mask and looked at the glove she currently had on and sighed, "Why do I have this glove?" She asked out loud. She took it off revealing dark energy around a clawed hand... Almost demonic. She put it back on, "Hopefully tomorrow it won't happen again..."

Dimentia watched Fawful complete a device, "You done?" She asked.

Fawful glasses started to shine once more, "Almost!"

Dimentio entered the room, "Hey guys! What's up?"

"Fawful's completing a device." She said.

"GOT IT!" Fawful's glasses gained a happy look, "YES! YES! YES!"

Dimentio's eyebrow rose, "So what is that?" He asked inquisitively.

"A device I've been working on for awhile. It'll help us know where we are." He said.

"The project has doness!" Master Fawful exclaimed.

"Really! Awesome!" Dimentio's eyes started to sparkle, "Now to go where no man has gone before!"

"Wow... Dimentio's putting lots of effort into this..." Dimentia started to smile, "Guess he isn't as annoying as I thought. So why did I not like him?"

Dimentio-sensei looked at the three, "Now then... If you have any problems, be sure to come back here. The only reason we're using this teleporter is because it's frankly more easy that way." Dimentio,

Fawful, and Dimentia were all in a metallic room, "You three ready?"

"One question Dimentio-sensei." Dimentio said, "Where are we going?"

Dimentio-sensei smiled, "Home."

A pink-haired girl looked up as she walked outside a hotel, "Great... My life couldn't be worse." She had a long sleeved sailor fuku and stockings, "First I get sent to this country, the Philippines, by my mom... Who probably is using the money that I worked HARD for herself. Plus, dad is off somewhere." She screamed to the sky, "COULD THIS DAY GET ANY WORSE!"

As soon as she said that, a multi-colored portal appeared before her, showing a young boy with glasses and a Raccon Mario t-shirt, a goth-looking girl, and this Org. XIII reject coming out.

The Org. XIII reject looked at her, "Hi. I'm Fawful212. Our sensei/master wanted us to come to you."

A strange ball came out of the portal, "I'm DAL 9000, your helper!"

"Dimentia... Can you believe that sensei let a robot help us... What if he..." The boy looked somewhat nervous...which was directed to the goth-looking girl.

"Look. He won't, sensei said that he's like a human. We have to help him." The girl said, rolling her eyes.

The pink-haired girl looked at the odd group, "My name's Akira. Akira Kogami. And personally, I REALLY don't want to be a part of your dumb group." She started to walk away...until she realized something, "I can leech off of them! ...This can help me..." She turned back around, "I'm really sorry for my grumpy frown! Here! I'll be a part of your group!"

Fawful212 looked at Akira, "Alright. Welcome to the group." He started to shake her hand.

"...Perfect."
