Trying to start with the heroes wasn't resulting in both groups being interesting, so I'm going to flip the script and do a dream team of the villains first, if that's cool:

- Demushu (Kamen Rider Gaim)
- Tenjuurou Banno/Gold Drive (Kamen Rider Drive)
- Masamune Dan/Kamen Rider Cronus (Kamen Rider Ex-Aid)
- Evolt/Kamen Rider Evol (Kamen Rider Build)
- Ark/Kamen Rider Ark-Zero (Kamen Rider Zero-One)

Basically I just took the most maniacal villains I could think of from recent Rider history and tossed in their pet Overlord whose simpleminded desire to fight everything in front of him seems almost benign by comparison. A fun villain team-up is all about the opposite of chemistry. I want massive egos with huge and conflicting plans for the world who are falling apart from the second they decide working together is going to help them somehow.

And who do I get to confront such an imposing group? Going by the "from the same show" rule, I have none other than:

- Ryouji Hase/Kamen Rider Kurokage (Gaim again)
- Jun Honganji/Kamen Rider Jun (Drive again)
- Haima Kagami, who was totally a Ride-Player that one time! (Ex-Aid again)
- Nariaki Utsumi/ Kamen Rider Mad Rogue (Build again)
- Yua Yaiba/Kamen Rider Valkyrie (Zero-One again)

So here I just thought of how I could make THE worst possible squad to handle all these huge threats to humanity, and then threw Valkyrie in there too, because leading this underpowered team of losers sounds like exactly the kind of undignified position she usually ends up in.

Could be a really good underdog story in here somewhere!
