How is it tough?

Since a bunch of the elements is there for the humor caused with the juxtaposition of Saitama's boredom with his vast power and your battle shonen tropes. 

With Saitama out of the focus  you get what amounts to a less Nascar version of Tiger and Bunny with goofier looking heroes.

It is tough because I have to a. find a way to limit characters' powers so they don't become overpowered but at the same moment allow them to be extremely strong and b. try to adapt the OOC so people that are unfamiliar with OPM still understand the overall mechanics and possible ploting.
