I just think the final stone should ditch the egg shape for the sake of being different. To set it apart from the other five. Also, what about the Omni stone itself? Did we discuss how that should look?

I dunno, just it being a meteorite gives the implications that the extinct are given an alien power, so unless that's fine with everybody else, I would like to see if we could weigh our options just a little more with ideas for what the extinct stone could look like.

btw, the reason I suggested a serated arrowhead was you probably don't realize this, but you can turn a serated weapon into a dinosaur head, as done by poiwer rangers dino charge.

I honestly don't think there's any kind alien power implication at all. It's not like its power came from a meteor. It's just common knowledge that most scientists believe a large meteorite ended the dinosaurs in some way, so by association their extinction could be represented with the shape of a meteor. Simple as that.

We could just say the meteor fused with the Extinct ' DNA or something like that.

Gaim had padlocks that summoned fruit that turned into ancient warrior armor. Not everything in KR has to fit one theme.

some of those locks not even being fruit at all.

This is going to be longer process than I imagined. A lot longer.

And cavemen used arrowheads, so it's not that big a stretch.

I don't even know why we're discussing this. Let's just go with the meteor shaped amber.i just want to start discussing the design of the villains.

Just to put here my 10 cents, I also think a meteor/asteroid/comet-looking amber would fit the extinction theme better and look freaking cool as a bonus.
