Periodic table of Godzilla elements

This would actually make a really cool poster if enough were found. The Killaak metal? Maybe the Seatopian sand? G-Cells? Regenerator G-1?

Granted some of these aren't "elements" but might be close enough ideas to make something out of.

Exactly. It may not be an element, but if it is important enough in the series, it should be placed in the table. Absolute Zero gun, Micro Oxygen, Godzilla's Atomic Breath. I think this would make a great shirt, but we need more things first.

Space Godzilla's crystals could be an unknown element. The weeds from Godzilla vs Mechagodzilla II seemed to have some unknown features too. 

Mothra and Godzilla eggshell.

the thought to be extinct trilobite embedded in godzilla's footprint?

The maser based weapons. The Hydrogen Bomb. 1954 Godzilla's skeleton and DNA.

I'm thinking that there should be something from Godzilla vs Biollante but will have to research it. This a really fun topic. Feels like a Godzilla scavenger hunt.
