Dreamweaver wasn't a normal quirk by any means. If anything, it was special. While a part of him hated to think that, Midoriya Izuku knew the truth had to be hidden away forever.
No one could know the full extent of his quirk. Even his parents couldn't know.
To the world, Dreamweaver let him adjust the dreams of anyone he touched while they were sleeping into something more pleasant. It was an emitter with a physical trigger of skin to skin contact. There was a time limit, only lasting seven hours, before the recipient woke up.
But that wasn't exactly true.
He couldn't just make pleasant short dreams that people would wake up from feeling refreshing. No, his quirk was so much more than that.
His Dreamweaver could at its base, let him control the dreams of those around him. With a simple light touch, he could change them to whatever he wanted. He could even keep them from wanting to wake up.
Poor Katsuki.
How many years had the blonde been stuck in his dream world of being the number one hero now? Five years? Almost six? It had been so incredibly easy to affect Katsuki, stubborn, brilliant, cruel Katsuki.
He didn't feel bad about it.
No one suspected the coma that the explosive blonde had fallen into was actually a dream world shaped by him. He had cried, big fake tears, when he heard his Kacchan wasn't waking up, but no one knew why.
Midoriya Izuku never told a soul about what happened that afternoon, that he'd figured out how to delay his quirk until the person fell asleep. He would never tell anyone about the months leading up to his revenge, how he'd practiced daily on his parents without their knowledge. With them, he was careful to help them wake up, but unless he guided Kacchan out into the world of awareness, then the blonde would remain trapped forever. And on the off chance he woke up, Katsuki would be devastated to learn it was all just one long dream. That he wasted years saving nothing, doing nothing, existing only in a hospital bed.
Which was fine with Izuku.
Some people would wonder what his poor friend had done to deserve this, but Izuku knew better than to admit anything. Because the brat absolutely did.
Bakugou Katsuki was a bully, an ass, and a murderer who would have gotten nothing but a slap on the wrist for pushing a quirkless boy out of a window to his death. Kacchan claimed it was an accident, that his quirk went off accidentally, that he didn't know Nakahara Shou was that close to the window. No one cared because it was a quirkless kid who died.
No one but Izuku.
Even his parents just tisked sadly, telling him that was just how quirkless were, weak, vulnerable, and breakable. The two heroes he tried to talk to brushed him off when they heard Nakahara-kun was quirkless, and the officers he told just laughed at him for even trying. It wasn't fair.
Izuku knew that if no one would punish Katsuki, then it was up to him. As the boy who had once been friends to both, he had the perfect way to get his revenge. He didn't have to do anything, just touch the monster, and let his quirk do its thing.
Besides, he was genuinely curious how long his quirk could last without being reapplied.
Was that vigilantism, he wondered as he held the letter from Yuuei in his hands. Maybe, maybe not. It was definitely justice though.
Plus, without Kacchan around, Izuku thrived. He was finally able to separate who he had been as a toddler to who he wanted to be. Izuku had been able to try new hobbies, talk to people without fear of getting bullied for his "weak" quirk. He could practice building his endurance and speed every day without worrying about hiding burns under his clothes again. Heck, he could even talk openly about his dreams of being a hero without being immediately shut down. It was nice.
It was justice. Nakahara-kun could rest in peace without fear of anyone else being hurt like he had been.
Which was an underground hero. One who would take the spot that should have gone to Katsuki, if the monster wasn't still asleep. He could help people who needed it, who deserved it, and maybe, just maybe, he could be more.
And maybe, just maybe, the worst of the worst could take a long, long rest. He was good at that.
He yawned as he opened the letter, listening to the message with half an ear. He needed a nap. Maybe he could visit Kacchan's dreams again, playing a villain or a hero that looks up to the blonde, just to make things even more devastating.
Izuku grinned, green and gold eyes mostly hidden behind heavy lids. He was going to be a hero. He was going to live the life, the real life, that Katsuki craved. Then, one day, when he knew that Katsuki could never ever become a hero, he'd help the blonde wake up and watch him shatter.
That was the least he deserved for his... actions.
If no one else would protect the quirkless, if no one else would at least try to keep them safe, he'd do it himself, leaving a trail of dreamers behind him if needed. After all, he just needed one single touch to catch them.
For now, though, he had things to do. Things Katsuki would never get to.
It was time to draft his first hero suit.
And if he happened to decide on a name for himself as well, then no one would need to know yet.
Somnus would keep the entire world in a peaceful dream if he had to.
The best part was that no one would know. No one could guess that the boy with the pleasant dream quirk could capture, lure, and trap people in their dreams until he decided to release them. His wrath would be hidden behind wide eyes and pleasing smiles until his victims fell asleep. Then they were in his domain.
He wondered passively if he could make nightmares too. Maybe. If anyone deserved to be trapped in never-ending nightmares, it was Katsuki.
That could be a cool experiment if nothing else.
He snorted as he sketched, Katsuki the guinea pig. Only alive to help Izuku gain better control over his quirk. The irony was as sweet as caramel.
