Where is the proof you may ask. In S4, Will showed Mike a painting of a three headed dragon
No. Ghidorah will not be in stranger things 5.
Ghidorah isn’t like even the first 3 headed dragon ever, hydras have existed all over in mythology, and the Slavic Zmey Gorynych also has three heads.
if this was at all meant to relate to Ghidorah, it would just be a reference.
Plus thematically the drawing wasn’t really supposed to be foreshadowing at all, it had more to do with will’s struggles with being gay.
...I have no words.
Also, G. H. (Gman), I 100% agree with you on this.
