As always, we'll have to wait and see, but for now I am convinced the name Gavv derives from ガブッ, the Japanese onomatopoeia for biting.

This is my thought as well

My cold shot prediction is the "VV" in the name will look like teeth or fangs in the logo

Exactly.

So, bite rider? Well, if his finisher was a bite instead of a kick and punch, that would be a really interesting innovation. Well, what a fitting way to celebrate Amazon's 50th anniversary.

A bite themed finisher could be pretty dang cool!

My wish: a plot in the style of a road movie set in an unusual world (fantasy, post-apocalypse, another planet) about a rider. You can use LED panels to create an unusual environment, most importantly, not all the time. Something like the story of Hokuto no Ken, but with a rider. Or even better: the main character accidentally receives a belt and looks for a worthy bearer for it in this unusual world, not noticing how he himself becomes one.

If it is "bite" themed I'm curious what that... actually means lol

One of the rumours going around before was the candy/snack stuff with the belt that chomps on the candy/snacks gimmicks right? So this could definitely tie into that sort of imagery

But, if we assume the biting nature is something uncontrollable, like a curse, then it is quite possible that the hero will be forced to choose between people and kaijins. And then the world would be better off being more like ours. Also, to complicate this choice, it is possible that he is hunted by a government organization that does not distinguish him from kaijins, and has its own riders/pseudo-riders.

Also, I'd like to see Gotchard take a cue from the previous show's 10th anniversary celebration. That is, have the tertiary rider wear a hoodie and transform with a bracelet instead of a belt.

The kids will definitely like this. Plus, we'll have a belt with a personality again, which doesn't happen often. It will be possible to arrange crossovers with Kivat and Krim.
