Quirk Swap

Royal Love

Izuku is a princess and Katsuki is a prince. They both belong to different kingdoms and since they were born her father and his mother agreed to an arranged marriage between the two. After the two of them turned seven their parents would bring them anytime they needed to see each other to allow the children to get to know each other. They would sometimes get along but most of the time they would bicker and argue. As they got older the arguing turned into teasing and turning more playful interactions, they would spar during sword fighting lessons, share interests for their future and go on 'adventures' together (just roaming around the nearby forests).

One day Katuski is invited to The Midoriya Kingdom by Izuku's father to discuss the agreement. When he learns the truth he struggles to see her in the same way. He suspected that these feelings were building but he didn't truly believe them, he just wanted his friend. But he didn't think that Izuku would be coming to stay a week late, the reason is that her kingdom is at threat of The Todoroki Kingdom and if anything was to happen to the king his daughter needs to be safe. The next few months Izuku is kept safe within The Bakugou Kingdom and she and Katsuki grow a lot closer. One day in the evening after dinner the two of them were sparring when the castle was attacked by people looking for Izuku, the two of them are able to defend themselves until their leader makes himself known as Dabi and they begin to struggle. During their fight he lets their intentions slip about "taking Izuku to take the kingdom much easier", this shocks Katsuki enough for Dabi to leave a gash in his arm. This distracts Izuku enough for someone to send a sleeping dart to her neck causing her to pass out. Katsuki tries to keep fighting but it’s struggling and Dadi is close to killing him but then an archer appears, killing Dabi and the others trying to take Izuku. The archer relieves himself as Shoto Todoroki, a son of King Todoroki but he has left his family after he learned his father's plan to either force Izuku into a marriage with one of his sons or to use her against her father to hand over his kingdom. Shoto works with Katuski and Izuku to stop this fight between kingdoms. A couple of weeks later Shoto discusses that Katsuki is planning to marry Izuku, Shoto agrees that it would be best to protect Izuku.

Wolf’s Trust

Izuku was abandoned in the middle of the woods, she would have died alone if it wasn't for the rescue of a great wolf. It was larger than most wolves making it more feared than anyone that saw it. But Izuku being so young wasn't afraid of it. The wolf would take care of her and she would take care of it. She called it Kacchan

One day while the two were walking they came upon a small town. Like always when they found one Izuku would go into the town for some supplies. But this day something was different, in the town a prince (Monoma) was doing some rounds when he saw Izuku. He found her very attractive and wishes to take her back to the castle. She refuses, to which Monoma uses his guards to try and take her. Due to this, she cries out that they're hurting her and Kacchan hears her. He took off running and found her quickly and knocked the guards away from her. He stood beside her and wrapped his tails around her in order to protect her. Monoma starts to bad mouth the creature causing Kacchan to pounce on him. Izuku had to calm him down and they left. Izuku and Kacchan had to move as quickly as possible from the village before they were found again.

One day late at night Izuku and Kacchan are ambushed. Izuku was knocked out when someone put a cloth over her mouth and nose while another person held her arms back. Kacchan saw this happen and became more hostile before one of the men said "fight anymore and we'll kill her", this caused Kacchan to stop fighting back in favour of keeping her alive. Kacchan was knocked out with a similar substance as Izuku and they were both restrained. When Izuku woke up she was in a comfortable bed, wearing new clothes and her hands were tied. It wasn't long until a maid came in with food and tea then left. Izuku was confused and ignored the food until hunger got the better of her. While this was happening Kacchan awoke in a cage with a muzzle on. Monoma approached him and Kacchan tried to growl but the muzzle stopped him. Monoma mocked how loyal of a pet he was but didn't know that Kacchan was more than that. About half an hour after Izuku had eaten she started feeling tired and weak, which is when Monoma walked in. He then sat beside her and started to touch her. She tried to get away from his action but she was too weak and fell to her knees. Monoma was satisfied with her state and pulled her up to hold her. He stated "your perfect for my plan" and then pushed her on the bed and got on top of her. She was so scared but she was too weak to fight back. She was close to screaming for help but Monoma told her "you scream and that mutt of yours dies". After Monoma had finished his business with her he left her in a puddle of her own tires and locked the door. He didn't have the intention of having her as his bride just as a toy.

One night Kacchan was visited in his cage by a sorcerer called Uraraka. She told him she was told to come here in order to fulfil the deal. He agreed and she turned him back to his human form. He walked into the castle and could smell Monoma, which annoyed him. He followed Monoma to a room, he stepped in and heard him say "are you ready my pet". This made Kacchan angry that before Monoma could even start he had grabbed him by the throat and already had him on the ground. Monoma was scared for his life and even more so when Kacchan said: "let us go and never come near her again". Monoma was only looking for his own self-interest and let the two go. Kacchan was carrying Izuku in his arms and brought her to a cave. The next morning Izuku woke to find a stranger hugging her, she was confused and scared until she thought she recognized him. He opened his eyes and looked into hers. He introduced himself as Katsuki Bakugou, a man cursed to be a monster until he cared for someone other than himself. She felt nothing different towards him and still felt love for him.

Detective Bakugou

Sherlock Holmes AU

Katsuki Bakugou has been London's best detective for quite some time now. Katuski was incredibly intelligent, but he also had a roaring temper. He works with his childhood friend, Dr. Izuku Midoriya. Izuku is the only one able to keep Katuski in line. After Izuku worked as a medic during a war he had a limp leg. When he returned, Katuski was happy to have his friend back safe. He moved in with Katuski after his mother died while he was away.

One day while Katuski was experimenting in his lab, Izuku came to him and explained that he had a new customer. His name was Shoto Todoroki, he wanted Bakugou to find his missing older brother after he received a letter from him years later. After some negotiation from Izuku, Katuski agreed to find him.

(Investigation)

Eventually, the pair were able to find the building where the brother was hiding. But it was revealed to be a trap. Katsuki shoved Izuku away, wanting to protect him, and found himself in an unfair match. He was able to hold his own until Izuku held a gun to his head and his hands held. Katuski stopped in order to protect his friend. The leader made himself known, requesting that Katuski make him something. A gas like poison to be released at the Todoroki Wedding, all the richest people in London will be present. They plan on ambushing the event with a mass murder of all the elites. Katuski begrudgingly made them the gas, due to them threatening Izuku's life. Little did he know that Izuku was able to escape and warn Todoroki as well as the police chief Iida. He had one of their street friends wonder near the place in order to slip Katuski a note: Izuku figured that the criminals had limited surplus and so when looking through his notebooks he found the most likely one he would make and sent an ingredient to nullify it, he knew that they weren't keeping him in good condition for him to break out. Katuski was impressed and proceeded to add the ingredient so the gas wouldn't work after a couple of days. Dabi went to greet his brother for a reunion and so they could get the gas into the wedding, little did he know Izuku had already warned him. He planned on keeping 'Touya' in his sights. He let Izuku know and things were falling into place.

On the wedding day, Shoto was able to make 'Touya' the best man in order to keep in sight. Izuku was able to get an invitation to confront Dabi. He was confused and unable to warn the others, he tried to fight him but Izuku was prepared and held his own. Meanwhile, Katuski had already placed obvious clues as to where he was. The police were able to arrive early. They arrested everyone and let Katuski free but not before he noticed something. One of the men was missing, Shigaraki. With that Katuski raced to the chapel.

Dabi couldn't hold it any longer, he knew he was trapped, so why not go out with a bang. When he handed over the rings, he had his gun ready. Once he had an opening he pulled it out and held it to Shoto. People screamed in shock but Izuku anticipated this. He already knew that Dabi had a special gun for fire. People were calling his bluff but Izuku intervened to calm them and explain the truth. Katsuki got there in record time, he got down to the maintenance room and found Shigaraki with the gas machine. They had a fight, Katuski won and cut off the gas flow. Iida, who came with him, tied up the Shigaraki. Katuski filled a bucket of water, passed it to Iida and took Shigaraki, walking off with Iida following. He made it to the main room, kicked open the door to a bunch of scared people and threw Shigaraki in. "Don't worry about the gas, already taken care of!" He proudly spoke. He looked over at Dabi and Shoto, "Just as I predicted." He stated smugly. He moved out of the way while motioning for Iida. The water was thrown on Dabi and Shoto, rendering Dabi's weapon useless. Katuski held out his hand towards Izuku and immediately caught Izuku's cane. Dabi was confused and didn't realize that Izuku had come up and had pulled Shoto out of the way. Katuski took his chance and got Dabi onto his hands and knees after a quick beating. "I think you might want to postpone it?" Katuski said, looking at Izuku and Shouto, only to be replied with "That's all you have to say!" From Izuku.

All the criminals were arrested, Katsuki and Izuku shared their accounts and they were personally thanked by Shoto and his fiancé. They ended everything with a cup of tea.

Izuku Midoriya works in the castle of the Todoroki Kingdom as a handmaid to Princess Fugumi Todoroki. The two have been close since Izuku started working at age 15 for Fugumi being 4 years older. She became a kind of friend to her brother Shoto Todoroki, in secret they would have small conversations. But Izuku's past would come back to haunt her when a dragon rider came to the Todoroki Kingdom. The rider was called Katsuki Bakugou. She was once friends with Katsuki but one day had to move with her family. During the attack, Izuku protecting Fugumi thinking the attack was for the family but when she realized it was for her Shoto becomes the protector. It wasn't enough and Izuku was taken by the dragon and rider.

(I’ve this idea for a while now and can’t think of anything to continue it sorry)

Quirk - Siren’s Eye

It allows the user to have similar abilities to a siren. If they makes eye contact with anyone, the victim will feel an overwhelming desirer to obey the user. The user can only control one person at a time and the control will be broken once eye contact is broken or the task is complete.

Because no one can make eye contact with her she wears special glasses that block all chances of someone falling for her quirk. The reason for the quirk being related to a siren is because of her incredible beauty.

Strengths - The task has an almost 100% chance of being completed - also the user will have a natural attractiveness about them which allows the victim to be drawn to the user.

Negatives - The quirk never turns off, so any eye contact has to come with a task.

Support - A specially designed set of glasses/goggles which a one way style material to stop unnecessary victims getting controlled.

Happy Birthday Tokoyami, first time uploading fanart. It’s Tokoyami in the deaign of the shadow man from Princess and the Frog.

Also, due to the prophecy people keep trying to him safe in order to stop the darkness from becoming unstoppable.

They are apprehended by King Todoroki's guards and taken to the castle. They learn who Izuku is and the king decides to keep him 'safe' but it's more like a captive. The king's son, Shoto, releases Izuku and Katsuki knowing that the darkness will never go away if Izuku doesn't stop it.

(I know it’s not that developed yet)

Inherited quirk au

After the sports festival due to Todoroki's inexperience with his fire quirk they are both taken out of bounds, Todoroki is announced the victor after Izuku passes out. Before she is able to leave for the award ceremony she is cornered by Endeavour again. He makes the offer for her to be engaged to Todoroki with the intention of their quirks producing a powerful heir for the Todoroki family. She refuses to say that her parents wouldn't allow him to only say that he has his ways.

Quirk - Nullify

This is an emitter type quirk that can turn off other people’s quirks. It works by the user having a radius around them that can turn the quirks off. With counselling or training they can change the size of the radius to make it bigger or smaller but be warned if it gets too big it can put a strain on the body. Even more training could result in them being able to single out certain people that don’t need their quirk turned off but much like before too many people with working quirks can strain the users concentration and physical state.

As a hero, I believe they would act as an underground hero much lick Eraser head but they can still hep out with larger style attacks with just turning the main threat off.

As a villain, they would be a descent threat and probably be being recruited by the League. They could force a hero into fighting group of quirked people while they’re left quirkless for the time being

The Map Pendant

Izuku is a boy living in a harbour town. One night there is an attack from pirates. Izuku tries to find his friend Uraraka but runs into trouble along the way. He turns a corner to find the captain seemingly looking for something. He turns around to look at Izuku and smirks. The captain begins to walk towards Izuku and in response, Izuku starts to run. The captain chases after Izuku until he runs into a dead-end where the captain is able to trap him. They have a short conversation:

I- what do you want from me!?

C- from you nothing. but you are going to give me and my crew really good pay.

He knocks Izuku out with a strong blow to the head, he tries Izuku's hands just in case and walks back to the ship with the boy on his shoulder. The rest of the crew make it back and the ship leaves with Izuku inside. Izuku wakes to see a blond-haired, yellow-eyed male looking at him. Izuku is scared but then is calmed by the man called Kaminari.

After a while the captain/Bakugou comes to talk to Izuku, where they have a conversation:

I= are you going to kill me?

K= if we kill you we won't get our pay. Why would you think that?

I= ‘cus when you hand me over he's gonna kill me anyway.

K= how do you know who our employer is?

I= ‘cus he's my dad.

Bakugou plans to release Izuku but they already made it to their location. Izuku snuck the necklace into Bakugou's jacket knowing he couldn't read it but to also keep it out of his dad's hands. Izuku is headed over to his father and Bakugou's crew is paid off rather well, leaving Bakugou feeling guilty. His crew makes preparations to leave when Bakugou finds the necklace and immediately plans to save Izuku.
