Hello! 
I’m sorry to bother you, but I was wondering if you could help me out, as I am aware of your vast knowledge on obscure monsters.
I have a fanfic called Age of Kaiju and I’m starting to plan out how I will incorporate Gamera into its universe. Since I’ve already done Gamera in his own fanfic, I want to only use some obscure monsters from his rogues gallery.
One such monster I’ve decided to use is the Gaira/Namagon creature from Gamera 3D (who I have renamed Gainamagon). However, I am also aware that another creature was planned for the film named Son Gokuu, but I can find no information on it except it was a mythical creature that would help Gamera battle Gainamagon. 
Do you happen to have any information on Gamera 3D’s Son Gokuu? Also of note, does any information exist on another obscure Gamera Kaiju named Leoman?
Thank-you if you do answer this.

I gave you a watch thanks to your kaiju profile on Hedorah, I loved the video

Since you have 3 different dA accounts, I’m rather confused.

Which one of the 3 linked on the youtube channel is the most focused on Brandon’s cult movie reviews?
