This one, i'm not sure what is happening here...

Mammoth Remix I suppose

Dual boomerangs is actually a really cool weapon. Have we had a Rider with a boomerang weapon before? I feel like it, but I can't remember off the top of my head.

Vice gets Sword Forms' shoulder pads as shields, it seems like.

Also, does Vice's head just, like, pop out of the hoverbike?

Den-O Wing Form used a boomerang.

Oh yeah! Now it makes even more thematic sense why the Den-O Genome has them.

The Double Bird combination seems awkward. If Vice was on Revi’s back perhaps it would be better. Don’t the coattails seem like they’re supposed to be tail feathers?

I feel like more CGI should've been used for Mammoth Remix

I can imagine when Daiji becomes a rider, he oughta gain himself a Devil too, except Vice’s opposite where he/she is a gentleman/lady - butler/maid. Like Deneb in a way, but not incompetent.

Vice is like Momotaros I suspect.

Don’t the Deadman Kaijin remind you of Blue Dragon’s shadows?

Likely, this is the pose before they remix.

Also, we are getting a Ton of looks at the Remix Forms. It's getting pretty cool.

The Deadman reminds me of the Imagin. You summon one and it ends up trying to fulfill your desire in a harmful way to become "complete."

At least that's the sense I got from the Saber episode.
