Operation: Dagon

What if the skeletal remains of the godzilla species that was found housing the larva of the two MUTO's to be repurposed by Apex after the subsequent death of the two nefarious insects. Having the remains be turned into a new weapon, to be reborn in metallic flesh, never to be given rest once more. Only for this experimental reptilian mecha to be taken into the custody & control of MONARCH after the destruction of Mechagodzilla, given the rightful name of the skeleton that it puppeteers; Dagon. Hidden within the depths of one of MONARCH's many facilities, to be repurposed to not be a weapon to oppose & usurp godzilla, instead to be a protector over the looming threat & unpredictability of the titans. Its pilot, Harold Newgate, can only wait for deployment once more... only for things to take a more drastic turn than expected.
