Mecha-Ghidorah!!!!!! Would be so ****ing awesome!!!! Or maybe use it to create a new kaiju from his and other Kaiju cells, a new origin for Destoroyah maybe or some new Kaiju. Maybe Kiryu has the memories of Ghidorah instead of Godzilla, who knows?
If people weren't lazy, we wouldn't try to be efficient. If we weren't efficient, we'd never get anything done.

Definitely a new Titan made from the head of Ghidorah and cells from other titans. They could blast it with radiation reviving it and causing it to mutate into a new monster. It would have the personality of Kevin( the best head) but be more cruel and angry because it remembers how Godzilla killed him. He will have nothing on his mind but to make Godzilla suffer by killing his subjects and destroying the world he wants to protect.
Have him be erratic and random with his patterns. A being of pure chaos to foil Godzilla ‘s natural order. I can picture him being the best and baddest rival for Godzilla suppressing even King Ghidorah and Destroyah.

Ye, I kinda agree with Lazy, MECHA KING G.

no clue because i guarantee mecha ghidorah, kiryu, or other giant robots will not happen
Look upon my works, you mighty, and despair

Maybe they could grow a new Ghidorah from it unique to the Monsterverse.

I honestly think it would be cool if they spark the head to life and it regenerates itself into a zombie-like KG. Even more powerful and out of control than the original.

Godzilla takes it and starts the Monster Island Puppet Show, Fridays at 6pm.

LMAO
