Tons of different kaiju out there.
Thank you.
If Boon is worried about copyright, there are tons of creatures and characters to draw from in the various mythologies across the world, including Orochi, the Wendigo, Kronos, the Cyclops, Hekatoncheires, the Hydra, etc. There’s definitely shortage of possibilities.
I beleive the selling point is the monsters for the films. Of course there’s also the option of making original monsters that also take on the tropes of Kaiju as well.
Even so, I think if he’s interested, he should go along with it.
