RabbitTank Sparkling huh?
So he injects a soft drink into his belt and he powers up via sugar high.... SOLD!!! :lolol

so how many riders do u think this series would have?

I'm thinking 2 or 3 in total xD

Ditto. Nitrogue and Bloodstark seem like the Mashin Chasers of the show.
But then again, maybe one of them or both of them will be evil Kamen Riders next year around the 1st Quarter.

Nitrogue and Bloodstark seem like characters who might turn good or be on their own side but I definitely feel that one of them will become a Kamen Rider.

1: The secondary Rider is indeed called Claws
2: Build appears in Ex-Aid episode 44 including his Gashat

Blood Stark and Night Rogue also appear to be 'Forms'...so, if they're the same guy, either they're Claws, or they're our Third Rider.

So does this mean the rumors about Ex-Aid ending at 44/45 episodes are true?

Or they're two different individuals. Their designs and combining weapon - and that they each have only one FullBottle - lead me to suspect someone (a later, third Rider, Claws, or Build) may use their FullBottles in the Build Driver to produce a split form much like Build's, half NightRogue and half BloodStark.

...That's why I said 'if they're the same guy'.

All I know is that I already am loving build in his pop rocks form:lolol
