What is your favorite rivalry between 2 Kamen Rider?

Those 2 Kamen Rider hated each other so much that their battle will be like a bloodbath

Knight and Ryuki. Those two were a ton of fun to watch together.

Quick question has Team Baron dance with me full song been released yet?

I want to do a poll about secondary Riders but the poll only allows 13 choices, so I'm just gonna ask you guys here: Who do you think is the most iconic secondary Riders, and the one who should be representing the secondary Riders?

For iconic I would say(not based on personal preferences) Knight, Kaixa, Garren(for many reasons), Zeronos, Diend, Accel, Meteor, Baron.

Who should represent? Knight.

Just split the vote and go with pre- and post Decade…

Knight. Probably.

Kamen Rider Ryuki may as well be retitled Kamen Rider Knight considering how much main character duty he pulled. There's being a deuteragonist and then there's functionally being the main character without the billing.

If that's the case, Kuuga should be called Ichijou: Feat. Kuuga for who did what...

I want to say Riderman since he was the original secondary Rider and set the tone for all the ones that followed, but his arc was an important but relatively minor part of V3. So I'd probably go with Knight, Zeronos, or maybe Accel. All three are really well-known and representative of the friend/rival relationship that the best main/secondary Rider relationships represent. I'd also mention Meteor, but I feel like he's less iconic overall than the ones I listed.

I also think there's a lot to say for G3, Gills, Garren, and Chalice, but those were multi-Rider shows that played up the various relationships more (yes, Ryuki was also multi-Rider, but the Ren/Shinji dynamic was still very prominent).
