10. King Ghidorah Was Originally Rainbow Colored
Sure, this tidbit may not necessarily concern Godzilla himself, but it pertains to one of his most famous enemies and is too interesting not to mention. King Ghidorah is a golden scaled three-headed dragon first introduced in Ghidorah, the Three-Headed Monster, and is commonly believed to be Godzillas greatest enemy. The character is so defined by its distinctive golden look that it seems impossible to believe that it was originally conceived to have rainbow colored wings and a purple body! Yes, Ghidorah was nearly a rainbow monster, which no doubt would have stripped the character of much of its menace. The production realized it wasnt quite working, and decided on the more menacing and elegant golden look it now has.
