Chapter One: Origin
Disclaimer: This will be a very strange AU. I don’t own My Hero Academia or Spiderman.

A female voice was heard saying,” Okay let’s start from the beginning this is the part where I tell you my back story right? Well, if someone told you that I was supposed to get a quirk from the number one hero and become a hero like him and I still thought an explosioning Pomeranian as a friend then I’m sorry that person lied to you.” She laughed at that part. She then continued,” The number one didn’t choose me he chose someone who he thought as a niece and well what can I say A different life chose me.” The girl sighed as she continued,” This is the story of how I Midoriya Izumi become the number one vigilante Arachnid.”
Oscorp
Izumi was with her class on a field trip to Oscorp. Izumi who was standing at 5’7. She had short green hair with a streak of white, she had green eyes. She had her school uniform as they looked around the lab area. Even though she saw this so many times thanks to her best friend Harry Osborn allowing her to see most everything she is still excited to see everything. She smiled as she saw Harry walking with his father Norman Osborn. Harry was a Japanese teen standing at 5’10 with short brown hair, and blue eyes he was wearing a private school uniform. His father was a Japanese man standing at an unnatural 6’5 with auburn hair that like his son was short with blue eyes, he was wearing a suit and tie.

Izumi smiled as she approached them and said,” Harry, Mr. Osborn morning.” Norman smiled as he said,” Izumi how many times do I have to tell you, You can call me Norman we are basically family.” Izumi smiled at that as she knew that every first Saturday of the month they ate over at one of their houses. Norman continued,” Hey who is picking you up, Izumi? I hope you’re not getting a ride with that delinquent Bakugo.” Norman Osborn said the name Bakugo with disdain as Izumi knows he never really liked him and after he found out he was bullying her and using his quirk on her threatened him with preventing him from going to any hero school if he did anything to her again. Bakugo never did anything to her anymore, It also seemed that the school or maybe the teacher was messing with her grades as he was fired and replaced with someone new. The new teacher was nicer and stopped anyone from bullying and everyone liked her except for Bakugo and his goons as they couldn’t get away with anything anymore.

She answered him with, “No my Uncle Aaron is picking me up. Though my cousin Hana was supposed to but had to cancel cause of hero work. “Norman nodded but it seemed like he was debating what was better Aaron or the Bakugo’s driving her home. Izumi never understood why Norman and her Uncle, her mother’s brother never liked each other as every time they had dinner at Izumi’s house he would show up and antagonize Norman. Her mom would get annoyed and after seeing her angry face both Norman and Aaron would stop.

The three of them walked towards the wall and soon Norman said,” I know you have seen everything in this area before, so I have here a special pass for you to see the special science area within reason of course. You can’t enter the closed doored rooms.” Izumi grinned but then asked,” What about Harry?” Norman said,” Someone has to keep the other students in line and Harry is the only person I trust.” Harry said with a joking smile,” What that means is that you trust Izumi here with your special area but not me.” Norman shook his head and said,” No Harry I truly need you to make sure not of the school kids from the two schools mainly Bakugo from messing things up.” Harry looked at Izumi and mouthed the word, “Liar.” Izumi giggled as Harry then looked at his dad with a smile and walked away, Harry went to the group and Norman after giving Izumi a special pass went to his office.

Izumi went towards the only door that never opened for her which was labeled High Research. Izumi used the pass and the doors opened and Izumi walked in. She looked around in many of these areas were locked and she knew the reason. Many of these rooms had a high risk of containment breach and the only ones who could stop it were special employees who wore hazmat suits and were allowed to use their quirks in these situations. In rare instances, Norman would step in but no one knew what his quirk was all Izumi knew was that he was stronger than a normal human and had resistance to many things like physical damage from anything less than a strength quirk or fire damage.

It seemed that research that Oscorp was doing in this area was on quirk animals. The law only protects quirk animals that can talk and walk like the principal of UA University Nezu. But still in Oscorp, the quirk animals are not mistreated they are taken care of and are in an environment that suits them. It was so good that PETQA(People for the Ethical Treatment of Quirked Animals) couldn’t make an argument to set them free. As Izumi walks she sees a door open. Izumi said,” I assumed that all rooms that are for quirked animals would be closed.” Izumi walks in figuring that it means it is safe to walk in.

As Izumi went inside she saw what was working on, quirk spiders There were no casings to stop the spiders from crawling out, but it seemed that the spiders didn’t do that, and saw a panic button on the wall. Izumi smiled but soon as she heard movement looked to the left and moved toward the sound. Her eyes widened, and a blush adored her face as she sees a woman near her age wearing a skintight suit that emphasized her curves, her breasts, and her butt with black with black cat ears and a black cat tail standing 6’2 with blue eyes. Izumi knew who she was, she was the Black Cat a famous thief/villain who was able to escape any hero who tried to apprehend her. Black Cat smirked as she looked at Izumi with her blush with that innocent-looking face.

The Black Cat said,” Why hello cutie. What is a precious kitten like you doing here?” Izumi whose blush got deeper after being called a kitten replied with,” That is not important but what are you doing here?” The Black Cat giggled and said,” Well if you must know someone hired me for a job.” Izumi groaned as she should have figured that might have been the answer. Izumi backed up as Black Cat walked towards Izumi. Izumi got scared as even though she knew that the Black Cat wouldn’t hurt her it is still scary to see an infamous person. Izumi went to the wall and smirked as she hit the panic button. An alarm was soon heard as Black Cat gave a look to Izumi and ran out of the door as three security guards and other employees came in with Hazmat suits. Two security guards chased after Black Cat and the last one led Izumi out of the room.

After a while, Norman rushed in and asked,” Is everything okay?” The security guard said,” Yes when we arrived we saw the thief Black Cat run out of the room and my two partners ran after her and we saw Izumi in the room.” Norman asked Izumi” Are you okay did Black Cat hurt you?” Izumi said,” I am okay and no she didn’t she was probably going to knock me out like she does to everyone else.” Norman nodded as he asked for Izumi to tell them what happened Izumi explained what happened when she entered the area. Norman nodded his head and said,” It's concerning that someone wants to steal a quirked animal that badly that they would hire a thief to do it in broad daylight.” Norman looked at the two returning security guards, but they didn’t have the Black Cat.

Norman decides to show Izumi around as he also wants to make sure that nothing else or a quirked animal was stolen as they wait for the police. After a few minutes, the police came, and one person came up and introduced himself,” Hello I’m Detective Naomasa Tsukauchi and I need to interview Midoriya here.” Izumi asked,” What do you need to ask me?” Tsukauchi said,” I just need to ask you about your encounter with the Black Cat. I also need to inform you I have and lie-detecting quirk so I can tell if you are telling the truth or not.”

Izumi nodded her head as Norman was pulled aside from a scientist. Tsukauchi asked,” What were you doing in there?” Izumi answered,” To look around as it had its door opened.” Tsukauchi nodded as he asked,” Why is the open door important?” Izumi answered,” The normal rule for me when I look around here is that if a door is closed it is off limits and if it's open I can go it and look around if I don’t touch anything in there that is not the panic button.” Tsukauchi said,” Okay. Did the Black Cat say anything to you in there on why she was there?” Izumi said,” She told me that someone hired her for a job.” Tsukauchi nodded as he asked, “Is there anything else she said.” Izumi said,” Not that can indicate why she was there.”

Norman came up before Tsukauchi could continue and said,” I have been informed that a quirked spider is missing.” Tsukauchi asked,” Is there any special about this spider.” Norman said,” Maybe we have any found quirked animal from the wild or rescued from non-friendly experimentations. We don’t know what they did to them, and it will take time to figure out what the spider can do.” Tsukauchi nodded his head as he said, “Izumi has provided what we needed to know. She can go now.” Izumi nodded walked out of the High Research and joined her class.

After joining and being asked a lot of questions they continued with the tour. After the tour was finished, they went outside to be picked up by family or friends and Izumi smiled as she saw a 6’2 Japanese man with black hair and black eyes wearing a blue tee shirt and jeans with a leather jacket standing in front of a motorcycle with a sidecar. Izumi smiled as she ran up and yelled,” Uncle Aaron.” The man smiled as he hugged Izumi and said,” Hey niece how was it?” Izumi answered with,” Good but I did encounter the thief Black Cat.” Her uncle asked,” She didn’t hurt you did she?” Izumi said,” No she didn’t.”

Aaron nodded his head and gave Izumi a helmet as he put one on. Izumi puts it on and they drive away. As they drove they had the radio on and heard about All Might saving people or another Endeavor getting sued about property damage. Aaron said,” That lawsuit will not get any motion.” Izumi nodded as they soon reached her home. Inko opened the door and said,” Thank you Aaron for picking her up.” Aaron said,” Hey that’s what a brother is for.” Izumi enters as Aaron leaves.
After that, they talked about what happened in their day. After a couple of hours of Izumi doing work and other stuff, they ate dinner and went to their rooms. As Izumi was working on notes she didn’t notice something crawling on her leg. She gets up and walks her bed and right before she laid down she noticed a spider on her arm and before she could do anything it bit her. Izumi gasped as she swatted the spider. But soon she felt funny and went and laid down her bed.

This is going to be where Izumi discovers her powers and comment on any Vigilantes for vigilantes, you can either make on up and I will give credit to you or one from marvel or anyone in MHA. Sorry if this is shorter than the last one

Izumi woke up but she doesn’t feel well. As she tried to get up she feels sluggish and warm as she walked out of her room she saw her mom standing in the kitchen wearing a suit and tie. When she turned around she looked at her daughter and said,” Oh Izumi baby you don’t look so well.” She walked up to Izumi and placed her back of her hand on her forehead and said,” You have a fever.” Inko then guides Izumi back to her room and asked,” Do you feel hungry?” Izumi nodded as Inko left and after a few minutes with Onigiri and some water. Inko said,” I would stay home today but I have a to go to work and with Hana still busy with hero work…” Izumi asked,” What about Uncle Arron?”

Inko said” I don’t want to interrupt him, but it might be the only way.” Inko leaves and after a few minutes came back and said,” He will be here in 15 minutes I will call your school.” Izumi nodded her head as she started to eat and drink. Inko leaves as Izumi lays down and closes her eyes for a bit after finishing her food and her drink. After a while she awakens when she feels something that she doesn’t know. She opens her eyes and she her uncle Arron opening her door. Izumi smiled as Arron asked,” Hey young blood how are you?” Izumi said” Good bit I don’t understand why I got a fever all of the sudden.” Uncle Arron said,” Hey its cool I like when I have an excuse to come and visit.” Izumi nodded as they talked about stuff. Izumi sometimes took a nap and woke up a couple of times but all the time she woke up she felt her head was foggy.

One of the times she woke up cause of the same feeling she felt when her uncle came into her room she saw a dark-skinned woman of average height sitting on a chair. She also sees rabbit ears and reaches out and pats the woman on the head and said in a raspy voice” Cute.” She goes back to sleep when she heard the women sputter out something to a someone who had a female voice laughing. Izumi went to sleep. After a while she woke up and felt better and her head was clearer then for the third time she felt the same thing from before telling her someone was in her room.

She looked around and saw a woman with long black hair with black eyes who looked around to be 5’6 with a semi muscular frame. She was wearing a tee shirt a skirt. Izumi asked,” When did you get here Hana?” The 24-year-old woman smiled and said,” Three hours ago you were out of it and when my girlfriend came in here to help me watch over you, you pet her head and called her cute.” Izumi blushed when she heard what she did. She covered her blushing face as Hana was laughing.

Izumi after being humiliated asked,” Did I leave a bad impression?” Hana said,” Naw I told her how you get when you’re sick remember what you did to Meru?” Izumi blushed as she remembered Hana’s exe-girlfriend from UA who had a cat quirk who was in the general studies course. When Izumi was 6 she got sick so both Hana and Meru looked after her and Izumi in her fever daze cuddled Meru to both Meru and Hana’s amusement. Hana even tries to joke about Meru liking Izumi more, but Meru was able to flip it back on Hana by first hugging Izumi closer to her and then poking fun at Hana about being jealous that Izumi got a beautiful girl faster than Hana did Hana was shocked at the turned around. Sadly, three months after they graduated UA Meru had to move to America as she got a good job opportunity over there.

Izumi asked,” What time is it?” Hana replied with,” Around 4:30 pm if you want to take a jog I won’t stop you, but I suggest not to be gone long.” Izumi nodded her head and got up Hana left as Izumi got some new clothes on. And left, she started to jog a quick root but with only 5 minutes in and no one around Izumi got grabbed into an alleyway. But as she screamed a bit a hand covered her mouth silencing her.

A man said with a knife in his hand said,” Hand over all your valuables and nothing bad will happen.” Izumi tried to get away but couldn’t as she tried to yell for help. The mugger said,” You must not be so bright no hero will ever come to stop a mugging when there is no witness.” Izumi felt hopeless as she remembered a lot of things about not being saved from being bullied for a long time. But she muffled said” I'm going phoo treated” The mugger said,” What?” Izumi brought up her leg and stepped on it. The mugger yelled out in pain and Izumi got a few distance away as he lunged.

Izumi said,” Back the hell off.” Red electricity covered her arm as she punched the mugger. He was sent flying Izumi looked at her hand and saw her sleeve damage asked herself,” What the heck was that?” Soon a male voice was heard,” That was interesting.” Izumi looked to her left and saw a heavily muscled man with a simple wrap-around black mask tied over the top of his head, a tight-fitting dark shirt, jeans, boots, and a long hunter green trench coat. She saw he also had a scar and a cane.

Izumi said,” You’re the vigilante Knuckleduster.” The man looked shocked but soon nodded and said,” You’re right I’m surprise you know me well anyway you know when the police see what happened and if you show that to any hero school they will arrest you for vigilante and unlawful quirk usage.” Izumi said,” I don’t know how that happened I’m… I should be quirkless.” Knuckleduster was surprised but said,” Maybe you’re a very late bloomer.” Izumi said,” Late bloomers don’t get their quirks at age 14.” Knuckleduster said,” Okay but to tell the truth they might just say it’s a quirk to make it easier.” Izumi nodded and said,” So I can’t be a hero than?”

Knuckleduster looked like he was thinking and said,” How you become a vigilante and join us?” Izumi said,” What do you mean Us? Have you started another vigilante team like you did with sky crawler and pop step?” Knuckleduster chuckled and said,” In a sense yes but its more complicated than that and I can’t tell you more unless you join. Look come to the alleyway near Kiyashi Ward Shopping Mall in three days’ time around noon and give me your answer then.”

Izumi was stunned at what he said and before she could say anything he walked away around the building and what sounded like a biwa was heard. Izumi looked were Knuckleduster went but didn’t see him. Izumi was confused but ran back home. As Izumi entered Hana looked over and when she noticed her sleeve ran up to her and asked, “Izumi what happened?” Izumi made up an excuse that Hana would believe. Hana didn’t look convinced but didn’t try and push. Soon Inko returned and while she was happy that Izumi was better but was concerned with the sleeve. After eating dinner, they went to bed.

Next day after school

After Izumi got the work she missed yesterday and able to avoid Bakugo and his goons Izumi went to an abandoned warehouse. She theorized on how she got these powers. She figured it must have come from the spider that but her on Wednesday she fingered it must have been the quirked spider that got out. Izumi tried to activate the electricity from yesterday but couldn’t. Izumi got so angry that she punched a metal beam and to her surprise she put a dent into it. Izumi backed up and her hands turned the wall and when she tried to move she stayed stuck to the wall. Izumi panicked and pulled at the wall destroying it.

Izumi’s eyes widened at seeing the two holes in the wall and the two pieces of the wall stuck on her hands. Izumi tries to get the pieces of the wall off her hands but after while she just took deep breaths and calmed down. Soon the broken pieces feel off her hands.

Izumi walked to unbroken and placed her hands on the wall and said,” I can’t believe I’m doing this.” She tried to climb the wall and she was able to get up a bit, but she always fell. But after a while and after calming down she was able to get to the ceiling and after crawling for a bit she started to stand on the ceiling and even ran for a bit as she is doing this she is thinking of Knuckleduster’s offer. After a while Izumi found out she was more athletic and acrobatic than she was before and the more accusive movements builds it up the red electricity from yesterday or it builds up on its own slowly. She studied the electricity and theorized that it might be a form of bio electricity. She also discovered the weird feeling allowed her to navigate when unable to see, hear after she had closed her eyes and had her ears covered noise canceling headphones. She gets back to the floor.

Izumi is considering joining Knuckleduster and she sits down. She couldn’t tell ever Mr. Osborn that she got bit by his spider as she didn’t have the heart to tell him about this as he might try and find a way to remove her powers. But she still wants to save people and remembering the no one helped her yesterday. So she decided that she would join up with Knuckleduster. She then left warehouse.

Two days later

Izumi got to Kiyashi Ward Shopping and went towards the alleyway and met up with Knuckleduster who said, “I’m glad you decided to join us. Hey Maestro, we ready” Before Izumi could say anything a Biwa was heard and they disappeared.
