Author's Note: Okay... Lets be serious here, I am not sure how I managed to get an entire chapter done after an agonizing day at work but here it is... Also, I am going to address something from one of my reviewers and clear some things here. Cy Man brought up to me several issues with the first chapter and some lore problems my first chapter had. While I do appreciate the feed back, but couldn't you at least not been such a genitalia about it man and not bring up the issues I already know I had for my first chapter. I will be honest with all of you and my first chapter was rushed, particularly the first half of it, as i was hyped up on adrenaline for uploading my first chapter, and I tried to lay down the ground work as best as I could in that state.

I also know that the Klyntars aren't normally born from eggs, but since Venom was, in Marvel Comic Canon, i decided to implement it for Toxin, though this chapter will clear up some things for this story's canon. I also know the Klyntars are Asexual, but I also came up with another excuse for their "reproductive work arounds" in this chapter as well. And Toxin is different in this one because I wanted to make a version of Toxin that is unique to this universe. There is also the fact that I didn't want to use Toxin in the first place, but a fellow author had convinced me to use Toxin instead of his grandfather, Venom, which is what started this whole mess to begin with

Anyway, I digress, while Cy Man was a real a Jerk with his review, he did have a point, and its the reason why I decided to try and revolve my stories around the Canon of both the Symbiotes and MHA as best as I can. And after this, I won't be posting any chapters for a few weeks, as things are about to get crazy at work with Thanksgiving coming up. The Next chapter will be the MikuPairing bonus chapter I promised you guys, and I'm going to take my time to get it right once the poll has ended. So please enjoy this next chapter, and I hope you're ready for a surprise in this one! WEB SWING!

Chapter 3: An Agonizing Alien

Finding his way back to UA, Izuku tries to find the classroom he is assigned to, trying to figure out where it could actually be. "Come on it has to be around here somewhere!"

Calm yourself Izuku, we've still got a few minutes before the ceremony, and by my calculations, we should be close now!

"Right!" Izuku says, "There it is!" Izuku finds the label for the classroom and he smiles as he reaches for the door.

Good, now all we can do is hope Glasses and Bakagou isn't here… Had no sooner than Toxin said this, they see the two arguing with each other.

'Just our luck…' The two think at the exact same time.

"So you're fromh some big elite school!?" Bakugou shouts, "All the more reason for me to end you!"

"How rude, and you say you want to be a hero!?" Iida shouts.

Alright Izuku, just enter slowly and quietly, and maybe they won't notice you!

'Right…' Izuku thinks, slowly placing a foot in front of himself and carefully stepping but that is when the floor creaks a bit and both of them look at him.

'CRAAAAAAP!' Izuku and Toxin think, thinking of rushing to their seat only for Iida to be in front of them in an instant.

"You! I am pleased to see you made it, I am Iida Tenya from Sosei Middle School!"

"M-Midoriya I-Izuku! A pleasure to meet you as well!" He shakes hands with Iida.

"I was actually impressed with your performance during the exams, not only did you not hesitate to go into action, but you had also deduced the true nature of the exam when I hadn't! Truly impressive!"

'No we definitely didn't!' The two think.

"Finally, I found my classroom!" Mikumo says, opening the door. "Izuku!" He rushes over and several tendrils with sharpened ends are aimed at Iida, Mikumo glaring at him. "Back off, you bully!"

"Mikumo, stop! He wasn't bullying me!" Izuku says, Mikumo looking at his cousin.

"After what he said to you at the entrance exams, yeah not buying it!" Mikumo says.

"It's true…!" A girl with black hair tied in a frilly ponytail. "He was merely expressing congratulations to Midoriya-kun, so please don't act like this!"

"Come on, Mikumo, you're better than this!" Tsuyu says, to which Mikumo looks at her then back to Iida.

"Tch, if I catch you bullying on Izuku again, there won't be enough of you left to fit in matchbox…!" Mikumo says, retracting his sharpened tendrils into his body.

"Hey you're one of the two who helped us out during the exams!" A familiar brown haired girl says, rushing over. "Thanks for during the exams, I'm sure a lot of us would've lost if you hadn't taken charge of the situation and rallied us!"

"I-it's no trouble!" Mikumo says, hiding his face under a hood made of Virus's body.

"Gero…?" Tsuyu asks. 'Is he shy around girls? Odd, he was talking normally when he spoke to me…'

"If you guys are done being all buddy-buddy then sit in your seats…" A voice says. "This is the Department of Heroics, not recess…" Everyone turns to see somebody in a large yellow sleeping bag lying on the ground, everyone shocked and wondering who he is, but Mikumo starts shaking in terror, noticing something around his neck as he crawls out of the bag.

"Oh no…" Mikumo says, backing up. "It can't be…!"

"Oh, something got you scared, Red?" Bakugou says, to which Mikumo grabs Bakugou by the shirt.

"Don't you know who this guy is!? THIS IS SHOUTA AIZAWA, ERASEREHEAD!" Mikumo shouts in terror. "He expels every class on their first day!" This causes everyone to look at Mr. Aizawa in utter fear, believing their Hero careers are over before they even started.

"Oh no…!" Izuku says.

"How do you know so much about me, kid? I go to great lengths to keep a very low profile…" Aizawa asks, glaring at the young man. "How do you know who I am!?"

"Well…" Mikumo says, bringing out a journal called "Hero Analysis for the Future" just like Izuku's. "While Izuku studies heroes and their quirks as a hobby, I pretty much do it for the sake of knowledge…" Mikumo turns to the page on Eraserhead, with highly artistic drawings and what scant information he could find in great detail, as well as theories on his quirk. "And for the sake of defending myself." Aizawa looks at the notes and he gets a look on his face that scares most of the students.

"Interesting, most of this information is accurate, though not all of this is public knowledge, how did you get this?" Aizawa says.

"I kind of took bits and pieces here and there and built up my own theories with what I had available." Mikumo says.

"Well I will say this is impressive, but you, or any of you, are out of danger. Instead of sending you to the entrance ceremony, I'm going to run Quirk Apprehension tests on all of you, so I want you all to be ready for this, and whoever falls into last place is going to be expelled!" This terrifies everyone. Slowly but surely, through each test, Izuku and Mikumo use their quirks subtly but with enough of a presence that it satisfies Aizawa, and by the end of it, they are in the top 5. The first day ends on an exhausting high note for everyone, though Izuku and Ren are especially tired, more mentally than physically.

"I could use a milkshake right about now…" Mikumo says, his head hurting.

"Same here…" Izuku says. "My head is pounding!"

It's not our fault, you two were trying to keep us from fully manifesting, which was causing you mental agony!

Trying to keep us within you whilst using our powers is rather taxing, as using us in only fractions is something we never trained for, at least not for percentages under 25% or lower.

We really should invest some time in practicing those levels, that would probably help these two get used to using only a fraction of our bodies!

Agreed…

'We're right here you know, we can hear you two talking…!' The cousins think to their symbiotes.

Sorry...

"Midoriya! Akatani!" A voice calls to them, revealing it is Iida, who walks to them.

"What do you want, Richie Rich?" Mikumo asks, still angry with this guy.

"I came to check on you two to see if you guys were alright, I could tell you two were struggling during the tests…" Iida says, his hands performing bizarre motions, "But I think it was more of you two not trying to show off, rather than you two actually struggling to keep up with everyone."

"H-hit the nail on the head!" Izuku says, shocked. "Well you see, our Quirks are pretty much identical… And…"

"We really don't want anyone knowing the full extent of our powers…" Mikumo says, calmly. "Our quirks also produce our costumes, so it's difficult to keep them underwraps, as our quirks appeared much later than most others due to Singularity Disorder."

"I see, so you haven't fully mastered your quirks! That makes perfect sense, you're still used to using them at full force, but not at any lower levels!" Iida says. "I believe i can understand that, and you are both at a serious disadvantage due to the lack of time your bodies needed to adjust and evolve in order to become accustomed to your Quirks!"

"Exactly…!" Izuku says, smiling, to which Mikumo takes mental notes for his excuse later on. "Anyway we were just heading home!"

"Yeah, see ya…" Mikumo says, walking away with Izuku.

"Alright, be here early tomorrow!" Iida says.

"Yeah yeah…" Mikumo says.

"Later Iida!" Izuku says, the two walking off. As they continue on and arrive at the train station, Mikumo smiles as he gets a devious idea. "Uh oh, I know that smile!"

"Lets try train surfing!" Mikumo says, smiling.

"E-eh!?" Izuku asks.

"Come on, Izuku, it'll be fun!" Mikumo says, smiling.

"Sorry but I think I'll take the usual way back home."

"Alright then, not gonna force ya1" Mikumo says, jumping up as Izuku enters the train, landing on the roof and using Virus to adhere himself to it while sitting in the Fudoza stance. "Alright, Virus, get ready to stuff yourself!"

You had me at "stuff myself"!

Not fair!

"It's against the law to Train Surf, Toxin, so please don't get angry…" Izuku mumbles.

But I'm starving here! Toxin then notices something, Pink Acid, 9 o'clock!

"Huh?" Izuku asks as a pair of arms pull him into a hug.

"Midoriya!" Ashido says, smiling as she hugs him. "So we're taking the same train home, this is awesome!" Izuku is turning a bright red, to the point he is glowing with heat, and Mina can't help but think he is adorable in this state. "Oh my, are you having some impure thoughts?"

"N-n-n-n-n-n-no!" Izuku says, "Absolutely not!"

"Oh calm down, I'm just messing with you!" Mina says, smiling. Despite this, her cheeks had a faint magenta coloring to them, her black and gold eyes merely watching him with adoration. This was Toxin, the vigilante who saved her from a villain who took over her body and used her Quirk against innocent people. Mina couldn't forget the moments she was in his arms during that shockwave, how he held her gently yet firmly, as if he were trying to shield her from a storm, and the tendrils wrapping around her body to free her, how they squeezed her tightly without hurting her. The most unforgettable moment for her was when Izuku's eye met hers and time ceased to exist as those precious seconds before his mask reformed were like an eternity. "Still I am excited that I get to talk to you more before we switch trains!"

"W-w-well I could make for worse company!" Izuku says.

"By the way, where is that hot-headed cousin of yours?"

"Oh Mikumo? He's train surfing to our next stop!" Izuku says.

"What? Isn't that dangerous?"

"Yes but it is kind of necessary for us to be something of workout maniacs and adrenaline junkies." Izuku says. "The Quirk we share is called Symbiosis…"

"Symbi-what now?"

"Symbiosis! You know how Tokoyami's quirk allows him to create a Living Shadow?" Izuku asks.

"Yeah, via his Dark Shadow Quirk!"

"Well we're able to do something similar, only difference is we made our bonds with microscopic organisms that somehow developed their own quirk!" Izuku says. "Would you like to meet mine?"

"Oh this is gonna be cool!" Mina says, not understanding a word he said but now excited to meet the being that Izuku's quirk bonded him with.

"Alright, just be prepared for something freaky!" Izuku says, concentrating as he offers his hand to her. Mina, looks as she gently takes his hand, both of them blushing, but then Izuku's Symbiote forms in his hand and connects them.

Hello, Mina Ashido…

"Who said that?"

I did… The two of them then appear inside of Mina's head, where they are on the location of the final battle of her favorite movie, Aliens, the Sulaco. She looks around, terrified, but then her foot lands in something sticky.

"Ew!" She says, stepping backwards, only to find the green goo has Midoriya in it. "Midoriya!"

"Be not afraid, child…" Toxin's voice reaches to her as the symbiote appears in it's suit form, with it's razor sharp teeth and claws. "We cannot harm you here."

"Who are you? And where are we!?" Mina shouts.

"I am consciousness of Izuku's Symbiotic Hero Suit." Toxin explains. "I am sure you can figure out what I am…"

"Wait…" Mina says, looking around. "You chose this area? Does that mean you are an alien?"

"Correct!" Toxin has vanished and walks around her as a hunter green version of the Alien Queen. "I am an extraterrestrial symbiotic being from another Galaxy, from the Planet Klyntar…"

"Whoa… An Actual Alien!" Mina says, her terror turning into excitement. "So you said you were a Symbiote?"

"Correct, Izuku's quirk, Symbiosis, made it easier for me to bond with him, as it allowed me to bond with him on a cellular level; we are now one, and we benefit from each other greatly. Izuku gains access to all my "Quirks" while his Quirk allows me to obtain both sanctuary and sustenance from his hormones and proteins." Toxin explains. "Please do not hate Izuku for hiding this, but if somebody were to discover me, and somehow managed to remove me from him, especially a villain, I would be forced to bond with them, causing my sense of honor and justice to vanish, turning me into a bloodthirsty monster."

"I see! Don't worry, Toxin, I'll keep your secret safe!" Mina says, "Not every day a girl gets to meet a real alien!"

"Speak for yourself, based on what Izuku has shown me, the stereotypical alien look fits you! No offense intended!"

"None taken!" Mina says, smiling, and the group is snapped back into reality just a minute before they pull into the station. "Man that was a rush!" She smiles at Izuku, "You took a big risk revealing that to me!"

"I-I know…!" Izuku says, "But despite everything, I have a feeling that I can trust you with this secret!"

"So does Mikumo have this kind of creature too?"

"Yes, his is called Virus!"

"Virus?" Mina asks.

Do not underestimate a Klyntar due to their name alone. Even the weakest of us, when bonded to a powerful enough host, becomes equivalent to your worst nightmares…!

"Wait did I just-?" she then looks down and blushes with a slight look on her face. "My so bold…!"

"Huh?" Izuku asks, looking down and letting go quickly, Toxin detaching. "S-sorry about that!"

"Hey it's okay!" Mina says.

My apologies but I just wanted to play with you both for a moment, and Mina, if you wish, i can contact my people's hivemind to see if they can send you a Symbiote as well!

"Can't you create one from yourself?"

That would be ill advised, a Klyntar who spawns outside of the conditions of our homeworld runs the risk of said spawn becoming corrupted. That had happened to me as well, until my Grandfather had me sealed in an egg to receive treatment for my corruption.

"Huh?" Izuku asks. "But I thought…"

That I was born from that egg? No, it was actually both my purification chamber and my transportation from the Andromeda Galaxy. We Klyntar normally don't hatch from eggs. Without a host, we're practically genderless in all sense of the words. Normally, our bodies generate "seeds" that we can shed from our bodies that become full fledged Klyntar once they bond with a host. However, when we obtain a host, we take on the traits of their gender, and modify our "genetic" structure to compensate and amplify their "Quirks". However, when two Klyntar, one that recently bonded with a male, and one that recently bonded with a female, come together, they amalgamate, and in doing so, are capable of producing eggs that carry Purebred Symbiotes, in which they can be raised in any environment and need not fear becoming corrupt until they bond with a host.

"I see…! Still, how are you going to get a Symbiote from Klyntar to all the way over here?"

The Agents of the Cosmos, an army of noble and honorable extraterrestrial warriors whom our people have bonded to, can transport one of our own to meet with you in secret and pass on a Symbiote to you. However, I must warn you that, like all of us, we have a dark past that we wish to expunge, and with that dark past comes a power known as Emotional Empowerment, in which your body will become stronger due to powerful emotions. However you will be tempted to utilize your negative ones more often than not, and doing so will corrupt both you and your partner.

"Thank you for the warning, Toxin!" Mina says, noticing they are pulling into the station. "Welp I'd best get going…! See you guys later!" She then rushes home, smiling about today's events, still trying to sort through all the information in her head. 'Despite having a huge bombshell dropped on me, I think today was pretty good!' She looks to see Izuku and Mikumo meet up, and then thinks about both of them have Symbiotes, and she begins to wonder what it would be like to have a partner like that. She enters her train and begins making her way home, to which she thinks about having someone like Toxin as a partner, but then again, what are the chances of something like that happening?

No sooner did the thought exit her mind, there is an explosion nearby, the young woman stunned, but something in her forces her legs to start moving, the young woman locating the source of the explosion her eyes seeing a pink and purple amorphous creature that looks like Toxin in its liquid form shielding innocent people from a Villain's attacks. "HAHAHAHA! You can't beat me, you puddle of sludge!" The creature doesn't speak but it's white eyes make it obvious it is angry, glaring at the villain as the young woman rushes over.

"Hey! Over here!" Mina says, rushing to the civilians and funneling them away. The creature looks at her and in its core, it senses something about her. Mina gets the people away, the creature moving towards her, it's menacing eyes having a softer feel to it. The young girl turns her black and gold eyes to reveal a woman in an odd military uniform, and in the back of her mind, Ashido can sense what the person is, and the symbol upon the shoulder patch is emblazoned into her mind. "You need a new partner to survive, don't you…?" The creature nods, and gently reaches out one of it's tendrils to her. "Alright… Let's go…!" She grabs it, and the creature begins to bond with her.

Thank you…

The next day, in UA, as the students get through their second day of school, everyone is wondering who their Heroics Teacher might be, and who should arrive but All Might, who smiles as he looks at the students. He has everyone change into their hero costumes, however, in the locker room, Mina looks at her Hero suit and smiles. 'Hey do you think you can copy my acid proof suit?'

I am bonded to you now, at least until the Agents come to collect me, so I believe I can copy the qualities of your costume until then.

'Thanks! And don't worry, we'll get you home! Hero's promise!' Mina says. 'Still it's a wonder how you Symbiotes can change your hosts like that…!'

I know it seems strange, but we Klyntar have to have a host to defend ourselves, and it requires a very careful balance of traits to draw out our greatest abilities whilst resisting our primordial traits.

'I understand… Still, I will keep an eye on you until your friends come to bring you home, and hopefully you can put in a good word for me to get a partner of my own!'

I believe that can be arranged… So… Do we have a deal?

'Of course!' Mina thinks, smiling.

Perfect…! Oh I had forgotten to give you my name the last time we spoke… My name is...

Author's Note: And that is a wrap on this chapter! I hope you guys enjoyed this and the little surprise I put into this one. To be honest I had not intended to have Mina learn of Toxin so soon, but after what I had went through with Cy Man's review, I had decided to accelerate things a little bit. And I want to know if you can guess which Symbiote bonded with Mina based on Color description alone. The First Five who can guess who it is correctly the will earn not only bragging rights, but... Lets just say that the prize involves them having an Agent of the Cosmos Oc coming to pick up Mina's Temporary Partner in a few chapters, as well as suggest a name for Mina's Partner later on in the story^^

Anyway, as I had said earlier guys I'm going to be taking a few weeks off in order to deal with my situation at work and to recuperate from the review that Cy Man had given me, as well get ready to make the MikuPairing Chapter I had promised you guys. So I hope you can all forgive me but that bad review, as well as its sender, had really put me in a dark place right now. I'm not going to do anything crazy, but right now I need to clear my head and refocus myself. I sincerely apologize and I hope you can all forgive me for disappearing like this, but I honestly need the time to deal with all the excrement that is going on in my life. Anyway, I'll catch you on the Flip Side! WEB SWING!
