Instead of Death Battle, RWBY watches arguably the best Cartoon Network show of the olden days of Cartoon Network.

These RWBY Reaction stories aren't exactly new but I wanted to throw my hat into the ring. Some above force has taken the RWBY characters to have them play and react to video games involving their multiverse selves.

As well all know it, and to the pure misfortune of Aizawa, class A1's the class that everything happens to. More specifically, a certain green bunny is also always in the middle of those everythings. So it really shouldn't have been a surprise when our favourite character got hit by a quirk during his internship with Endeavour. A simple mistake really, a small fight, some mistakes being made, a bigger fight because of those mistakes, etc etc... but what happened in between those fights was one little quirk accident. After learning about the quirk they dismissed it as harmless and it wouldn't have any affect on people. But of course, this is Izuku we're talking about, something has to go wrong. So let's watch as some new types of Izuku's from different universities join Izuku and his class for a really strange get to know you. So hop along for the ride as Izuku's friends learn more about him in one day then what they did in almost a year. Every part of Izuku and his thoughts out in the air for everyone to see. (AN: Idk how this will go so wish me luck. As surprising as it is MHA and all its characters do not belong to me! All and any masterpieces of art used are not mine, credits go to the artworks respectful owners. Also own nothing except the events in the story. Hope you enjoy!)
