the Eggalomaniac uses this because he has the crystal of destruction

equally as powerful as sword of creation

Well...

I think we should leave this as a theoretical weapon

With the story I have planned this likely won't happen. Sorry

oh ok
well then I'll make it like this:
the Eggalomaniac combined the Eggscalibur with the power of the crystal, and made this.

Mr. Void has the crystal

This seriously cannot happen

IT'S AN ALTERNATE DIMENSION

Oh

NVM then

Just wait until that knife goes in and steals it and become his bröther
