Speaking of Den-O, does anyone else feel like Gaoh should've been the main villain instead of Kai? He looks cool, sounds cool, has a badass rider form, and mere powerlust is more of a motive than Kai had.

1) Besides just Wizard, Beast, & Wiseman, couldn't they just make another secondary rider/mage before Beast? Like say.... he's from Section Zero?

- Wizard: He was involved in the ritual and he was able to suppress the Phantom through hope.
- Beast: During an excavation, he found the belt sealing the Phantom Chimera.
- Wiseman: Fueki lost his daughter Koyomi. Drowned in despair, he created Carbuncle and placed it inside his Underworld.

But if there was another... we know a Phantom called Drake became Sorcerer, there can be someone who easily drowns to despair, cause he doesn't have a future... but wants power. Eventually, this Phantom comes out seeing its Gate's memories, he'd rather fulfill his Gate's dreams rather than destroy people's hopes.

I can imagine him fighting like Vergil from DMC since Wizard fights like Dante.

2) Too bad they could've added more Phantom generals. We had Phoenix, Medusa & Gremlin. But Haruto's friend Kazuya could've become one. Couldn't they just make Kazuya one, just to add one more?

I'm disappointed in Kai and Nega Den-O.

I mean, they should've made an alternate timeline counterpart of Ryotaro with good luck. He'd be controlling the Imagin and transform into Nega Den-O instead.... but a Liner Form kind of look.

Absolutely he should've been the main villain. He was perfect for the role, and it's one of the biggest disappointments of the season he wasn't the Main.

A mop would've been a better main villain than Kai. Not like a talking, sentient mop. Just a regular mop leaned up against a wall or something.

Is kamen rider ghost like kamen rider wizard?

Ghost still has yet to première.

So what's the deal with Narutaki? What is his goal? Is he a villain? Hero? Comic relief who bitches about Decade being the reason a car driving through a large puddle soaked him? Haven't seen and probably won't watch Decade for a while.

Narutaki barely amounts to anything at all. He's probably closest to that last example.

He's supposed to reinforce that Decade is ultimately a villain.
However, Decade sucks and is bad and is a fucking waste of time, so it's unresolved and Narutaki is more of just a nuisance by series end.
