Megalon is an alter ego of Calvin's Mother, and "ancient arch-rival" of Godzilla, who was in actuality Calvin. When Calvin was pretending to be Godzilla, he saw Heather, his mother and spewed water at her, which he imagined was "a mighty fire ball". After this, She chased her son back upstairs to the bathtub where he came from.
