I Love how the edge is a mammoth snout as well. Nice little detail they added.

I like how at a glance, he looks like a color-swapped Den-O. This is probably the closest to a Legend Rider form out of the bunch. Of course, I won't jump to conclusions since there's still more as of yet unseen.

These legend rider forms are awesome. They're not just the old rider designs slapped over the suit, it's a blend of the current style and old details with a creative animal twist.

Revice is shaping up to be fantastic design-wise.

I like how I can see the Den-O in there but not if I didn't know to look for it to begin with.

Den-O is about trains,one of Go-Onger’s two train-themed Enfine is a Mammoth Engine, coincidence?

Yes, probably a coincidence.

lol

I wonder if the inspiration for those odd positions when they combine to form their transformed animal might be from that Japanese game show Brain Wall.

oo maybe, perhaps

The Shiva Sisters to whom Daikaijuman was referring are an incarnation of the ice-elemental Shiva Summon which appears often in the franchise, but in XIII there are two of them and they can combine in to Snow's awesome motorcycle! I can definitely see the resemblance to Revice.
