Eiji's parents are alive, as far as we know. We had no info on many other Riders' parents, like, say, Godai's or Hibiki's.

Shotaro's parents are never mentioned, presumed alive?

If Roidmude 006 wasn't destroyed and his body possessed by Banno, what would you imagine his advanced form be? Since 008 is Tornado.

Exceed Gills is SO incredibly badass one of my favs!

I think I'd just have a bit more action in Kuuga.

There's some cool stuff going on, but I feel that it can get a little boring at times.

Also: Ultimate Kuuga's rider kick. I wanna see that.

But it would destroy the planet.

You don't see Ultimate's Rider Kick. You just see the oncoming wall of destruction coming towards you.

Would have that been true or just another hyperbole in the series?

considering his midway powerup can cause almost nuclear effects, I wouldn't be surprised if his ultimate rider kick COULD destroy the earth.

Believe no one.
They're all fucking liars.
It's just hyperbole.
The size and radius of his kicks don't match how large they tend to describe.
