Time Stops For No One is a My Hero Academia roleplay server taking place in an AU where All For One, arguably the most influential character in the anime/manga, was never born in the first place. As such, the quirk One for All was never created by him, meaning that the world never had a Symbol of Peace and crime rates are as high as they have ever been.
By virtue of so many quirks never having been removed from the gene pool, the superpowers possessed by humans are more powerful and complex on average than in canon MHA, making the numerous Outlaws that roam the streets significantly more dangerous. The world needs even stronger Heroes than ever before to keep them in check, and UA University is the place where the best of the best, those whose quirks have power rivaling that of top Heroes, are trained.
So knowing this, what will you do? Maybe you'll become a Hero fighting for justice on behalf of those who can't protect themselves, or perhaps member of The Crimson Wing, a villainous organization that seeks the destruction of the very concept of order. Perhaps you'll choose to pursue your objectives on your own as Vigilante or Villain. You're even free to just sit back and watch chaos ensue.
Regardless of your choice, be sure to write a story you can be proud of, because time will neither wait nor turn back for those who don't.
