This is somthing I worked on that is a crossover between RWBY and MHA. I have 7 chapter already done but I will say yes this goes through the MHA story with RWBY Characters in it but is is mainly from Ruby's POV for the majority of the time.
Disclaimer: I only own one character in this entire story no one else.
MY RWBY Academia Prologue
Welcome to the Super Human Society
"In our world, about 80% of the world is born with a superhuman ability known as Quirks" A silver eyed girl said as she was writing in a notebook "Due to that a new profession was born known as Pro-heroes with scenes played out just like in comics."
"Oh, sorry journal, I should mention I am Ruby Rose and one day I will be the number..." She said when a knock on the door came "Huh?"
"Ruby, it's your father" a male voice came from the other end "Just wanted to let you know if you don't leave now you going to be late"
"Ah! Sorry dad" Ruby said rushing to get out of her seat tripping as she does. We see her room decorated in hero memorabilia with some posters of well known heroes like White Thorn, All-Might, Kamui Woods and a few others. It also had a very rose theme to it with pillows and curtains
She gathers her things and opens her bedroom to be greeted by her farther Taiyang.
"Honestly, you not going to be a hero if you can't keep track of the time" Tai said with a smile
"Haha, very funny dad, where's mom and Yang?" Ruby asked him grabbing some quick toast
"Yang has already left for class at UA while your mom has been busy on a case at her agency so she left really early" Taiyang explained
Ruby nods smiling. Her family was a little mixed in terms of some areas for one her father was in the 20% of people who were born quirkless but it hasn't stopped him from being able to support his family and be a good person teaching at one of the local schools
Her sister Yang is more of a half sister, she is currently nearing the end of her first year as UA, the top academy for Heroes, it is the place Ruby wants to go and this year she is able to qualify for the entrance exam. Yang's homeroom teacher is there uncle Qrow.
Her mother Summer Rose is the Pro-Hero White Thorn and is where Ruby mainly gets her powers relation from. Summer is one of the best heroes, least in Ruby's eyes, holding the rank 22 on the Pro-Hero Boards.
"Well, I best get going" Ruby said speeding to the front door "See you later dad!"
"Ah! Ruby I said be careful using your rose tornado in the house!" Tai said only for the front door to close he sighs and goes to get ready himself
The house was more an apartment complex and Ruby was walking to the stairs she spots one of her friends who lives in the same apartment complex "Hey Izuku!" she calls out running up
"Ah! Oh, hey Ruby, how are you today?" Izuku said jumping from the sudden shout
"I am good, ready for another good day at school?" Ruby said as the two walked
"Yeah, I am mostly just hoping Kacchan isn't too hard on me today" Izuku said as he walked with her
"I really don't know why you let that guy walk all over you" Ruby said shaking her head "I mean I know you two have been friends a long time ago but he has changed too much"
"I guess but I have my reasons" Izuku said with a smile
Ruby looks at him concerned. She was aware Izuku desired to be a hero but didn't have a quirk but she admired his spirit. She remembers the first time meeting him.
Flashback
We come back to several years ago a young Ruby who was in kindergarten at this time, was out with her sister Yang and they walk near a park. Ruby notices three kids beating up a young Izuku who had stepped in to defend another kid.
Seeing how rough the blond haired boy was going to deliver an explosive punch. Ruby moves to intercept taking the blunt in her shoulder leaving a mark on her shoulder
"What the…?" The blond said surprised
"Why don't you leave them alone?!" Ruby said tears from the pain in her shoulder
"I don't know who you are, but that quirk of yours is nothing compared to mine" The blond boy said with a smirk punching his hand making an explosion
"No Kacchan! Don't hurt her!" Izuku said crying as he looks up from the ground
"Shut up Deku, she got involved she gets the same punishment you getting, maybe she will put up a fight" Bakugo said with a smirk
"Want to rephrase that?" one voice said and the three boys look to see Yang glaring as she was in, as she was in her rage form her blond hair glowing and her eyes fiery red it was intimidating especially to kindergartners
"Oh...I think I hear my mom calling!" The boy with wings said flying off followed by the other one.
Bakugo was a bit nervous but was better at hiding it said "Whatever, this is a waste of time, just next time remember your place Deku" He then runs off
Yang sighs calming down she looks to Ruby who was helping Izuku up "Are you okay?" Ruby asked him
"Y-Yeah...sorry about….getting you involved?" Izuku aid noticing the bruise on her shoulder
"It's okay, I just acted and didn't think" Ruby said rubbing her head
"Seriously Ruby, I can't believe you did that, you know you still not used to your quirk" Yang said going over "But I am proud of you baby sis"
Ruby smiles and looks to Izuku "Why didn't you use your quirk to defend yourself"
Izuku looks down "I'm...Quirkless" he said in a low voice
"Oh...well that isn't so bad" Ruby said surprising Izuku "Our dad is quirkless but he still amazing"
Yang smiles and moves back letting the two talk.
End of Flashback
"Ruby! Izuku!" A voice calls out bringing Ruby out of her flashback and sees another friend of her and Izuku, Oscar Pine. Someone who goes to the same school as Ruby but they all three take the same train so they walk together
"Hey Oscar, did your aunt enjoy those cookies my dad made?" Ruby asked him
"Yeah, she really did, she promised to make a pie for you to say thanks" Oscar said
"Awesome" Ruby said smiling
"So Izuku, found out any new facts to add to your journal?" Ocar asked Izuku
"Of course, here let me..." Izuku said but was cut off by a loud noise the three look and saw a huge creature on the train lines causing havoc "Woah! That is one huge supervillain!"
"Let's go watch" Ruby said excited and the three rush up.
As they watched they overheard that this guy attempted to stach a purse but lost control of his quirk. The Pro-Heroes Death Arms and Backdraft were ensuring the public safety
"Man, I am not sure if we'll make it to school in time at this rate." Oscar said
"Ahhhh!" Ruby said amazed as she saw a figure approach in "Look guys it's Kamui Woods!
The villain growls "Get away from me or I'll break you toothpick!"
"Oh this is going to be good!" Izuku said with a smile
"I agree, he might be new but he already made a big name for himself" Oscar said with a smile
A man next to the three notices said "One look at those dopey grin and I can already tell you three are fans"
"Uh...kind of..." Izuku said embarrassed
"Well I am, Kamui is one of my current favourite heroes. If he ever starts an agency I want to work along side him!" Ruby said with a smile
"I thought you wanted to work with your mom, White Thorn?" Izuku asked
"I mean yeah I do, but I want a chance to prove myself without people thinking I am mostly being helped by her" Ruby said rubbing her head
"Speaking of..." Oscar said and points as a white cloaked figure jumps into the battle sending some powered leaves at the villain stunning him a bit in surprise.
The figure looked like a much older and more mature Ruby complete with the hair colour and silver eyes after her hood came down. She was Summer Rose aka the White Thorn. She looks to Kamui "Like some help with this guy?"
"Through I am sure I can handle him alone, I won't refuse the offer of a more experienced hero" Kamui Woods said nodding.
"Don't sell yourself short, I've been meaning for a chance to work with a great up and comer like you" Summer said smiling.
The two rush in to fight the villain and Summer uses some fresh leaves she has in her bag and sends a Diamond storm at him knocking the villain allowing Kamui to get into position
"Assault, robbery and Illegal use of powers during rush out traffic! You are the incarnation of evil" Kamui said as he gets his super move ready
"Evil is a strong word for this guy. I go more annoyance" Summer said getting another diamond storm move ready just in case.
"There his special move!" Izuku said pointing
"Come on tree man show us something flashy!" The man calls out
"This is great right Ruby? Ruby?" Oscar asked and looks at her and sees literal stars in her eyes
"I can't believe my mom and Kamui Woods are working together!" Ruby said this was the best day for her now seeing this live.
"Preemptive Binding: Lacquered Chain Prison!" Kamui shoots out wooden branches at the giant villian.
However suddenly a giant woman came out and knocks the villain down shocking everyone in sight. Turns out this was a new hero here Mt. Lady and because she finished off the villain folks cheered for her, or just happy for a moneyshot.
"Wait...she's getting all the credit?" Kamui asked still in stunned shock
"Don't dwell on it Kamui" Summer said patting his shoulder
"Geez, talk about a spotlight stealer" Ruby said a little angry at Mt. Lady's actions
"Maybe but the important thing is the villain is stopped right" Oscar said
"I know but I wanted this to be a perfect moment for two of my favourite heroes, even if one is my mom." Ruby said nodding "What do you think Izuku?"
The two look and notice there friend already in his notebook writing in an entry for Mt. Lady reviewing her quirk and possible weaknesses and mumbling to himself making the two sweatdrop one thing they know is that when Izuku gets on a thought train, he really gets into it.
"What's that fanboy? You taking notes over there? I assume you three want to be heroes too huh?" The man from before asked them
Izuku looks and smiles before saying "Yes, more then anything"
"I definatly want to be one too" Oscar said with a smile
"It has been my dream to be one like my mom, and I will be" Ruby said nodding and looks up to Summer who was still comforting Kamui and noticed her. Ruby waves to her
"Don't worry Ruby, trains will restart soon" Summer calls out but adds "I hope you get a good grade on the homework expected to be handed in today"
"Ah!" Ruby said shocked and realised she forgot to do it she looks down "Ohhhh..." she groans saddened by that fact. Today started so well but this is some of the down moments of the day while Oscar and Izuku pat her back.
Well there we have the prologue I hope you like this as I have other surprises in store other then some nice Ruby and Summer Rose interactions in store I gave a lot of thought with this series
