Sinister is going to try to create a "Super-Omega" mutant and will end up regretting it like Magneto did.
Magneto once tried to create an
artificial super-mutant ("Alpha") and ended up being regressed to childhood by it. Sinister is looking to play around with the genes of various Omega-level mutants, including several
Reality Warper types. He may end up the victim of his own creation(s), as will Krakoa.
