I'll confess that I was wrong about Shoji being the most recent, as I forgot that Kamen Rider Bake exists.

Making Gavv the show where two rangers became riders. That's kind of wild in hindsight.

Wait for it...

That teal and yellow combo for Plasma is awesome.

Nice shot

While not exact, this gave me a flashback of that one shot of Kotaro and Nobuhiko in Kamen Rider Black Sun where they are clenching onto each other's outerwear collars.

I'm guessing his Rider form will look slightly less evil.

In hindsight, having a protagonist Kamen Rider in a black suit pitted against a rival/nemesis in silver and framed like that shot has to be a subtle nod to Kamen Rider Black and Shadow Moon. Yes, Zeztz's suit design is a nod to the OG Double Riders, but having two individuals in a Kamen Rider show respectively in black and silver give off strong Century Kings vibes.

Neat interview with a producer on Zeztz.
