Maybe the Assault Wolf key still lets Fuwa transform while Aruto uses the Assault Trigger? That would answer the "what does it do without the add-on" question.

Zero-One theme song stuck in my head. TM Revolution does not disappoint.

Old, but, I think we could talk about it

No Burning Falcon yet.

But how do you think you'd picture Zero-One's final form? I know it's early, but just thoughts before that form can reveal to us.

I wonder if Aruto will finally get Flying Falcon back from Jin when he beats him with Shining Assault Hopper.

I would picture it as... Don't know really. We know he's using something on the side of his belt for it. So... I would have that look like the center of Ichigo's Typhoon, but Zero-One style. And have a unique ProgRise Key called Justice Hopper, abbilty Heroic.

I would have the form be a mixture of all his Hopper forms. With a unique spin on it. Not sure what that would be though.

Btw, Metal Cluster Hopper comes out March, I think? And Rampage is February

If they first end up siding with Thouser, Jin will eventually choose to join Zero-One. Hopefully Jin ends up with Burning Falcon and Aruto has Flying Falcon back.

RKF gives our best look yet at Thouser.

Thouser with black mask and purple eyes? Interesting. Maybe Thouser have two helmets with different colors.

while I preferred gold/silver/blue, gold/silver/purple is kind of unusual and looks cool too.
EDIT : oh and beetle faceplate is black now
