I don't know if there are any candidates already, but I would really like to try and write the story once we've finished everything.

The writing part is going to be a lot of work so we're going to need a group of people. You two can be two of the people helping to write the story. Yuu, we'll save all those dark parts for you because I want some "juicy" parts in this. The story is going to be the very last thing though.

I must warn you though, my stories can get really messed up to the point that it could easily fit in an adult horror visual novel.

Maybe I'll just settle for a couple of two parters

I'm all for adverse effects from the final form, but we don't want it to rip off Blade/OOO/Gaim, TOO much. :p

Don't worry I can handle the messed up stuff, but let's not put too much of that in the story since it's about a hero.

If you want we could make it that using the final form could kill him instead of turning him to a monster. And since said form is extinction based, we could make it that using the form slowly destroys his body and fossilizing it as he uses it .

Is there a summary of the custom rider so far? I'm interested in what's been developed, but there's a lot of pages of brainstorming and revisions to go through.

Page 97 or 98 for the summary, page 100-101 for the design

Hmm, reading back on the themes relating to the final form reminds me of something I tossed around in my head recently. When the protagonist acquires his final form, it was a point of divergence in the fictional history, one where he was able to overcome the challenge (physical and/or mental) and achieve control over his final form, and the other where he does not and gives in to the uncontrolled power (which could turn into one of them alternate timeline movies). In addition to the fossilized look of the form, the driver itself would be the one that's slowly fossilizing as he uses it, because the uncontrolled power the hero is suppressing with his will is slowly damaging the driver instead. When it comes to the end of course, there could be a final moment where the driver is nearly completely fossilized, and the hero may have to make a sacrifice to go into that last battle.

Let's not make the final form fossilize him or turn him into monster. Let's just make him lose his mind when in that form and go crazy. Later on he can overcome the effects and control the form.

Or we can make it like Kuuga Ultimate.
