Ramón appeared in the 1980 movie called Alligator. Although small by the standards of many kaiju, remember that this mutant Alligator grew up in the cramped sewers underneath Chicago, IL (USA) and didn't have enough time to mature before encountering humans and their explosives. There are sure to be even larger creatures lurking deep in the sewers and forbidden swamps that will someday rise from the muck and destroy.
