Godzilla: King of the Monsters - King Ghidorah / Monster Zero

I was brought on to the Godzilla: King of the Monsters pre-production phase through Studio ADI to help design Rodan, King Ghidorah and Mothra. Before focusing on Rodan, I worked on King Ghidorah / Monster Zero. I went through a handful of designs, starting with quick thumbnail silhouettes, then flushed out / blocked out, rough 3D concepts all under the supervised by Tom Woodruff Jr.
This design explored the tail bone structures.
