I finally watched Majuu Senshi Luna Varga and it was pretty good.

This is the OVA that Trixie The Golden Witch once described as revolving around the protagonist's Vagina transforming into Godzilla.

I initially suspected that she might have been exaggerating how much the creature actually looks like Godzilla.  Then the first time I looked at clips from it I went "yeah Toho could probably have sued them".

Now finally watching the OVA proper I'm back to thinking maybe he isn't quite that identical to Godzilla.  In episode 4 another Kaiju shows up, they are called Varuga, and it in some ways looks more like Godzilla and in some ways less.

All that was just the matter of if these Varugas look like Godzilla.  I was not expecting episode 4 to also possibly imply some Lore that makes the Godzilla resemblance perhaps thematically relevant.
