Explain what you mean by lemon energy and max flare.

Edison is a bit of a lesser version of this example but allow me to explain.

Lemon Energy was used by Gaim, Duke, and Baron.

Max Flare was used by Drive, Mashin Chaser, and Mach

That's how I've seen it anyway, Ghost used it, Specter used it, and while Alan didn't have a Driver, he still used it on experiments.

I think what Enchilada meant to say was that Edison has become widely used by more than just one rider much like how Gaim and Baron used the lemon energy lock seed when it is Duke's primary go-to lock seed.

Lately it's been the secondary rider who is the character out of left field that we haven't seen before and the tertiary rider is the character who's obvious. (Mainly with Drive with Gou and Chase.)

Heck that's even true with OOO, Birth was out of left field and then Gotou became the next rider.

That must be a hint without a doubt.

Someone who attended the pre-screening of Chou Movie War Genesis sketched Necrom, but he lifted his face up to quickly, so Necrom's face might be incorrect.

Honestly that face doesn't really look like anything, and the rest doesn't tell us a whole lot either. It does look like his head shares a lot of the same details the other Ghost Riders do, so that's interesting (if it's accurate, that is).

Well, I hope we'll be getting official pictures around the time Genesis comes out.

Good point - even with Wizard, Gaim (arguably), and Double.

So I was looking at stills from the latest Genesis trailer and in one of the shots Boost is totally using the Sunglasslasher.

Man, make up your mind, Toei.
