As boring as Shin Godzilla's movie was, I think you're low-balling him quite a bit. Shin Godzilla vs. Evangelion also proves this otherwise.
If anything, it'd be more or less a case of "what happens when an unstoppable force meets an immovable object?"
"Get off my god dang lawn, or I'm gonna kick yer ass!"
With the most recent exception of Cetrion in MK11, the Gods and the Elder Gods have no backstory. Only that they've governed the course of the realms since the beginning of time. Since the theme of the MK games has always been how gorey one can kill the other with their fatalities, and how progressive the series became once MKX was made, sex isn't really something the series will ever tackle, nor is it something they really need to...
Who would that make Rodan or Baragon? (depending on which movie this references...)
IIRC, the specials were made because of COVID interfering with their schedule. As for the monster count, last I heard, the team blew their budget when they made Genegarg (Which might explain why Alien Barossa looks so "cheap"). Not sure what the deal with Destrudos was, but by that point, I stopped watching the series. I gave up on Ultraman Z after that crappy resolution to the Red King arc they had going on, but that's a convo for another time/place...
Glad you like the pics! A lot of people I've spoken too really like that first pic too. But I had to include the other one(s) since I like Arstron.
