Senshi Sorauoko

Senshi is among the most powerful characters which is due to his quirks. He can get a bit out of control at times, but has matured and can, for the most part, control himself and his quirks. He was born into slavery, got freed and became a hero, saw his mum die and so tried to gain the power to stop people from dying, leading him to become a villain. After years of pulling the strings in Japan, he was defeated and banished himself to an island, where he stayed until Jennifer came and introduced him to Seattle. Now he helps people out indiscriminately as he isn't allowed to become a hero again.
== Description ==
=== Appearance ===
He is 6'2 with quite long black hair. His eyes are also black, but could be a good indicator to see how uncontrollable he is, if they were yellow, it's best to get away. Because of all the injuries he's sustained, he was given the power to stop ageing once something traumatic had happened, but in this case he activated it instantly, making him look around 24. But unfortunately stopping him ageing did not prevent him from getting other injuries and so wears a mask to help him breathe.
=== Personality ===
Senshi does have some slight anger problems, but only really shows itself if he's reminded of traumatic events, or a friend is on the verge of death. Other than that, he's normal and likes to joke around, even more so since he knows he can practically get away with what ever he wants
=== Quirks ===
Light Sword - This was Senshi's natural quirk and wasn't given to him by All for one. It allowed him to produce a sword made of plasma, that emitted a red light. He could also manipulate certain aspects of it, for example he trained so it could come out from anywhere on his body, how many of them there were and how long they were. 
Copy of All for One - This was given to Senshi by All for one which allows him to harness other people's quirks. It isn't exactly the same as All for One's as it does have a limit, which is unknown, but Senshi has manipulated this so it can control other people's quirks rather than outright taking them. 
Control - This quirk gives Senshi the ability to have more control over himself and his surroundings, which allows him to keep himself younger. And how powerful he is linked to his emotions, if he is angry, he'll become much stronger but lose control. 
Sense - This quirk lets Senshi know certain things around him, like who they are and can be used to know if anyone he knows is in danger.
* Telepathy - This grants him the ability to communicate with other people over long distances, though it is more difficult to use with people he doesn't know.
* Project - This allows Senshi to create a hologram like person that can do stuff which he might not be able to do if it was miles away.
Alter - This quirk allows Senshi to change certain things, which could be used to move things with his mind, to change a wild animal's mind, taming it.
* Telekinesis - This gives Senshi the ability to move things with his mind, whether it be objects or people.
* Alter environment - This goes well with telekinesis as it allows Senshi to change certain parts of things, like moving a tree root out the way, or healing an injury someone has.
* Affect mind - This allows him to alter people's minds, commonly used to tame animals, to conceal himself so he won't get recognised or to trick someone into doing something.
Though these quirks are powerful, it takes up a lot of Senshi's energy, especially quirks that affect other people, like healing them or even bringing them back to life.
== Backstory ==
Senshi was born into slavery for a Japanese mafia where he lived with his mum. Then after an inspection with by a small squad of heroes, he was found and liberated from it. The mafia covered up their slavery by dening it and saying they were paid for manual labour, which meant Senshi could get freed since he was only a child, but his mum had to stay there. 
From then on, Senshi wanted to be a hero like the people that had rescued him but was unfortunately he was deemed “too emotionally unstable” and so wasn’t accepted into any hero schools. However, one of the heroes that had freed him was keen to train him, despite him already having another apprentice. His name was Seishin seikatsu-ryoku and his apprentice, Nomusuko. 
While Senshi was still training, Seishin and Nomusuko were called to take care of a villain, although Nomusuko defeated him, the villain had killed Seishin. Having to fulfil his master’s role, Nomusuko kept training Senshi who was still rejected into the hero schools. When Senshi reached the age of 15, he took part in the Provisional Hero Licence course, which Senshi managed to get into and ace. 
Now officially Nomusuko's apprentice, Senshi went on a further 7 of being a hero, defeating villains and developing his quirk, all the while All for one began to get into his head. He said how if Senshi joined him, he could give him much more abilities which could even stop people from dying, the ne thing Senshi wanted most at this point. By the time Senshi was 22, he had fully sided with All for One, and carried out as he called, Operation Long Knife, which saw a massacre of the vast majority of Heroes across Japan. In return All for one kind of delivered his promise to Senshi. All for one entered him into a program that gives people the ability to take people's quirk. Despite all the other candidates dying, aside from Nine, he survived, and as a test, he took 3 people's quirks, which included Control, Alter and Sense
For a further 17 years, Senshi basically ruled Japan, not for power but because it stopped a lot of crime and villains. He managed this by using a network of Japanese gangs and mafias to keep control over their local area. A lot of these gangs were either on board with Senshi's plan, or just in it for the money. Everyone was so scared of what would happen if they did anything villainous, that they didn't even try it. This technically did make Japan safer, but made also made it a much more scary place. Soon, Senshi challenged All for one, though it was unclear why, most likely over disagreements about who was leader, and during the fight, All might showed up and defeated the now weakened All for one. Amidst the chaos, Senshi escaped. 
Although he'd later banish himself, in shame to what he had caused, to a small island off the coast of Washington, America. He lived in relative peace, with heroes keeping a close eye on him in case he'd try anything. Senshi lived like this for 6 years, until he decided to head to Seattle when he was 45.
