GFan, I call him "Aspiga" as well, seeing as that's what he's called in the original dubbing for "Son of Godzilla" and "Destroy All Monsters".
Until 1998, Toho's official/international name for the monster was "Speiga". Around that time they switched over to Kumonga. I've never let someone "tell me" I "have" to use whatever over another. I say rock the hell on GFan. Make up your own mind and call him what you want.
