I am here for superhero AU!!
Kageyama Tobio: Universal irreversibility to pair with his kingly image. He used to be really reckless with his powers and that lead to him being disliked and even considered a villain by some. After learning the appropriate times to use them effectively and for the good of others, as opposed to just himself, he becomes a one of the most renowned and loved superheroes ever.
Yachi Hitoka: Yachi can totally see into the future! Like, always small things that never make sense to her at the time but once all the pieces start falling into place, she’ll be able to make decisions on whether to either change it or let it happen. Will only ever use her powers for good. She doesn’t know how to control her powers and they can be a little inconvenient at times.
Iwaizumi Hajime: Iwa has the power of electric manipulation. He’s by far, and always has been, one of the most responsible and well-controlled with his powers. Sure, he’ll give some people (namely Oikawa) little zaps every now and then but he would never use his powers arbitrarily. He’s a hero is every sense of the word, always trying to do what’s right.
Kuroo Tetsurou: The power of suggestion. Kuroo might not always use his powers in the most serious ways but he’s never irresponsible with them. He’s definitely not a villain but he’s not a straight-laced hero either. Likes to toe the line between the two and sometimes pisses off the other heroes when he doesn’t agree with their methods and does things his own way. The results are usually good though.
Ho ho ho~ Alright! Lets do this.
Nishinoya Yu: Mentally generated weaponry/objects. Luckily he was in a confined area when this was discovered. The first time took so much concentration he passed out for 3 days.
Sugawara Koushi: Power of Healing! His heart is so open to the world around him. He draws his energy from organic life and it filters into life energy. It can be dangerous at times so he can’t go placing his hands on just anyone. The way it works is he cleanses his energy with raw organic matter and when he puts his hands on someone, he exchanges their energy with his clean one. Then disposes of it when he has time to cleanse. But if he runs out of that type of cleanser, it will exchange with his own and he will start to get physically sick. So he really needs to think before he acts.
Hinata Shoyou: Danger sense. When he found out what his power was, he literally yelled. THAT’S IT?! His danger sense can depict which direction the danger is coming from but he has yet to figure out how to pinpoint.
This is so much fun!
Michimiya Yui: Emotion manipulation; she is able to help her friends and teammates smile when hey are down, and can calm people down when they are angry. A negative side effect of this is if the other person’s feelings are particularly strong, she will end up carrying those feelings for a while until she can release them.
Tanaka Saeko: Super speed, she can easily breach the speed of sound while at a light jog, but she has yet to reach the speed of light. Along with this, she has a super high metabolism, she could probably eat a whole hog roast and still feel peckish.
Oikawa Tooru: Luminescence. He can literally dazzle people with his smile, leaving them blinded for a few minuets. He never needs to worry about being scared while going to the toilet at night, as he can shine bright enough to not have to turn on the light. He has to sleep with an eye mask on though, as he cannot sleep if it isn’t 100% dark.
