A blueprint of a suit Eggyhead designed that he can't actually build

Materials:
Crystal of Creation
Crystal of Destruction
Reality Ruby
The Golden Egg
2 Dimensional Diamonds
8 bars of Galactic Gold
3 bars of Omega Alloy
1 Multiversal bar

No no keep going what else

that's it

Collector: eggy, I'm not sure ANYONE can build this

And what is the purple gem on the left?

(Currently there are only three chapters who canonically know about it, Mr. void, creator, and the banisher. Unless I missed something)

(*characters)

i have one random idea

Eggy: Idk, heard about it somewhere, don't know much about it though.
