Summary
Emitter. Mutant. Transformation.
The older generations liked to tell the tales about the old days, a time of peace (not really but roll with it), when no human had a quirk. But all that changed when a glowing baby was born. Only the government, master of bad decisions, could have prevented what came next, but noo, experimenting on babies is deemed atrocious and inhumane by most civilisations. More than 100 years have passed, and humans have yet to resolve their differences.
Eleven years ago, my mom went to the grocery store to get cleaning supplies, leaving me to watch All might’s debut video for the thousandth time. Some people believe there will never be a hero that will surpass him. But I know. I will not lose hope. I believe that one day, Windex will save the world.

Summary
Izuku’s struggling.
His twin brother was kidnapped and the police have no leads. To keep it from going public which could put his brother in greater danger, the principal of UA asked him to go undercover as Kyodai.So now Izuku's attending UA (his dream university), making friends (which he's lying to constantly), and arguing with his hotheaded roommate (who's unfairly attractive, but also a dick, but also maybe kind of... not? It's complicated and Izuku really can't deal with complicated right now).
On top of all that, he's juggling hero courses and classes and training with All Might. And now he has a Quirk to figure out as well.And then there's Bakugou (the infuriating roommate whom he mentioned before).
Since the sludge incident, the blond's been different and Izuku doesn't know what to think. When it comes to Bakugou, his feelings are all over the place and he doesn't understand them half the time.But the longer the mission goes on, the closer they become and Izuku doesn’t know how to balance all the lies he’s telling.
He knows the truth is going to come out. He just hopes when it does, it won’t blow up in his face.*NOTE: You'll need to read A:G&R to understand*

Summary
According to his parents, Bakugou Katsuki died during his first ever heat after presenting as an omega at the age of 14. His best friend, basically his older brother, mourned for him and cried for weeks unable to get out of bed. Eventually he figured he had to move on with his life, live the life Kacchan would have wanted him to. Two years pass and not a day goes by that Izuku doesn’t miss his little brother. Then one day everything changes when he hears screaming coming from the house next door, Kacchan’s old house. That in itself isn’t strange but the blur of ash blond fur that flies out the front door and to the woods was what caught his attention. Especially since he only knew one wolf that could possibly fit that description. Before he had time to think he was chasing after the wolf and leaving his pack behind.
