Chapter 1: SUGGESTIONS
This FF's main focus point will be Hit's Time-Skip/Lag abilities in MHA.
However, the problems are:
(Tell me if you agree with the solutions, how i should change it, etc)
Problem 1. Timeskip is useful in a close combat/melee instance, but against opponents such as Dabi, Todoroki, Stars and Stripes (Elemental/Long Range/OP like Stars and Stripes) it's quite meh.
Solution 1. Give MC a secondary quirk that isn't OP, but would be helpful, like giving him a quirk that allows him to control "energy" (Ki), or minimal Ice/Fire, or a multiplier/boosting quirk, etc. (Obvi he would still train in martial arts, gym, etc).
Problem 2. The Power scaling in MHA is quite.. iffy? One second it's a normal hero high school, then we have AFO, then Shigaraki AFO, Stars and Stripes. and those OP ass quirks/people
Solution 1. Instead of upgrading Timeskip as slow as Hit did in DBS, make it so its easier to train. So like by UA, MC could skip time for 3 seconds (not best amount) for example. That may sound OP, but with the quite normal bodies of MHA its decent at best probably. (i havent watched/read mha in a while, i might be wrong/most likely am)
Solution 2. Make MC have some natural Limit Breaker like Saitama, where he has no max strength and constantly grows.
Solution 3. Make Ki a natural energy in MHA, but only MC will know of it and how to use it.
Problem 3. There's probably some other problems and solutions. This is where i want you lot to give tips/suggestions in paragraph comment/main comment
