Who of the Kamen Rider Club is a Zodiart?
 

This is something I've been having fun theorizing. I wonder if one of them will turn out to be one of the bad guys, undercover.

I have gone over all the possible suspects in my head and my favorite one is JK. I could see him actually being fairly nuts but hiding it behind a smile. A liar has to know how to be convincing.

I think Miu is too independent to be fooled, Daimonji and Nozama might be too overpowered with guilt to cover their identities, and the rest of the group seems genuinely against the Zodiarts.

Unless Kengo has some motives he's not talking about....

Who have you suspected of treason? :p

My money is on Yuki =p She just hides it with her adorableness and her songs of Hayabusa. That and the way she dodged Perseus attacks the other week. Her only motive would be to evolve so she could travel into space i guess =P

My money was on Kengo originally, given how much he resented the Kamen Rider Club, but he seems to have moved past that now. And given JK's introduction into the Kamen Rider club, it won't be surprising if he ends up betraying them.

Creepy Tomoko seems like the obvious choice.

Honestly with how controlling, and evil hot, Miu is I'd put my money on her to be the traitor

I was actually thinking about something along the lines of this back when we were introduced to the concept of surpassing Last One/becoming a Horoscope. I wanted it to happen to see Gentarou and the club deal with the consequences of failure, having someone they tried to save/befriend turning to the "dark side." Then I took it a step further and thought about if one of the club members would become a switcher and this might happen. I was considering either Kengo or Yuki, as either of them becoming a Horoscope could lead to some real good drama/storytelling with the right writing.

Kengo could be the likely one the more I think about it. He's obviously frustrated by his inability to become Fourze. His frailness or disease, whatever it is that makes him unable to become Fourze, is obviously something he hates. I think if he had the opportunity to use that power that he might. Maybe at some point he'll be faced with the temptation to use the switch and give in. Once he does, who knows if he can comeback. He may not be able to let go once he can actually reach the same level of power as Fourze.

Now this sounds really good and if it doesn't happen then It will all be deca.. I mean Den-o's fault.=p
I'd say anything like this wouldn't happen, but who expected Eiji to become a greed? So who knows, it'd certainly be interesting to watch.

its rarley ever the one you suspect the most, nor is it the one suspects the leasts ussually. it is ussually the one you suspect the middelest. and i suspect miu the most middlest...wait does that not make it me suspect her the most...my brain...

I know that I've joked that given the writer did Gurren Lagann, that they'll kill off Gentarou and everyone else will then have to become Fourze.

Interesting theory though. Whatever the case, Kengo is probably the best candidate. Plus, he'd make sense as someone to target given he's essentially the field commander who does all the tactics/strategy.

After all, Libra is FAR more tactical in his choices of switchers than Ms "Hand a switch over to every pouty kid I see" Scorpion was. Plus, he has the shapechanging ability to disguise himself - 'twould be easy for him to sew discord and sway Kengo over to his side.
