Monarch is a secret government organisation that studies kaiju in the film series that incorporates "Godzilla" (2014), "Kong: Skull Island" (2017), and "Godzilla: King of the Monsters" (2019). These films are predicated on an ecological theme. Godzilla is a primordial creature who feeds on radiation, returning to the surface world to restore the so-called "balance". It is unclear what the symbol itself represents, but it could be the wings of a butterfly. Or, indeed, Mothra.
