The first character sounds even with mental limitations like S class because he/she falls under the boundary manipulation power

BOUNDRY MANIPULATION
Capabilities : The user can manipulate boundaries - material, spiritual, conceptual, metaphysical, and so on. Since everything is physically and existentially defined by boundaries, the possibilities offered are limitless - for limits themselves are nothing more than the boundary Possible/Impossible, and the user can manipulate even that. Simply put, there is ultimately nothing the user cannot achieve

Sorry to sound like such a meany but we need to be careful with such abilities.

It would with only a slight increase in power make one a god/goddess
