It really all depends on whether you find being covered in gold statues ridiculous in a charming or unpleasant way.

So Zi-O Trinity is Zi-O's Climax Form and Grand Zi-O is Zi-O's King Form/Grateful Damashii pretty much.
Zi-O Trinity is alright, love the CMYK color palette they got going(Cyan for Woz, Magenta for Zi-O, Yellow for Geiz, and then the suit's base color being Black). Also like how the watch strap part on the helmet reminds me of Kamen Rider ZO a bit. I think it will look better in live-action as most of these tend to do so looking forward to it.
Grand Zi-O looks great and a nice nod to Blade King From mostly and also a bit of Ghost Grateful Damashii.
Also, judging by how Kuuga, Kiva, Decade, W, OOO, Fourze, Ex-Aid, Build, and Zi-O is positioned on the flyer scan, I guess the heisei rider engravings on the armor will most likely be in this order.

Kamen Rider Kikai actor revealed

Just stumbled across this. So we basically have Kamen Rider Kikaider.

Also so much denim, I love it.

Kamen Rider Kikai is Rento Makina. He... loves to cosplay as Jiro from Kikaider because trivia. :lolol
For those still wondering who the actor is, he was the ice-eating gangler Zamigo in LvsP.

Oh haha Toei. I wasn't actually expecting this LOL. But he's a Super Sentai actor as well, though...

Now I want a secondary Rider called Kamen Rider Hakai.

What I found funny since you brought up the Hakai bit is that Kikai's color scheme to an extent is close to Hakaider's with the primary black and yellow/gold parts with bits of red. But mostly feels a lot like Gold Drive. :lolol

The full suit actually looks amazing for just being a repaint with a new helmet, really wish we got this as the design for the Guardians in Build.

Looks like a rejected Build design.

The suit is a modified Guardians suit after all.

Zi-O Grand is so silly but it works.

Trinity on the other hand...
