The MUTOs come from the same era and ecosystem as Godzilla, they are Godzilla's natural enemy like Lion and Hyena. Think about it, they nest their eggs near radiation sources and the first set of eggs where found inside what could possibly be a Godzilla skeleton. Back in prehistoric times there were no man made nuclear reactors, so they had to get the radiation from more...organic sources, like Godzilla. Even if the MUTOs themselves are not parasites, their young parasite of Godzilla species, killing them by stealing their life giving radiation. That may be the reason their claws generate EMPS, somehow they soften up Godzilla making him easier to kill. Like with some versions of Superman, kryptonite doesn't take away his powers but he is now vulnerable to injury despite being powerful. The females grew big to defend their nests from Godzilla and the males gained flight to hunt down Godzilla and/or find mates. The MUTOs are a species that evolved to fight/prey upon Godzilla, Godzilla's species naturally hunts them down with extreme prejudice. They are unique from Godzilla's previous foes since they were actually designed to not be just a powerful threat, but to also actually kill him.
