A frog Rider and a lion Rider. I guess Riders can be anything these days, huh.

Lazer Boost looks pretty sweet! I wonder if Ziin's going to have to sacrifice himself for Ace to get his Lazer Raise Riser though.

Considering how these Riders are from the future, it makes sense that the idea that Riders can be anything can be taken to a whole new level.

He'll probably give Geats an extra one. Hope he sticks around him, Tycoon & Na-Go.

Oof. I am not a fan of these Sponsor Rider forms on the whole... And most of them being big CGI monsters is not helping.

Y’know it would be pretty funny if Toei/Bandai’s takeaway from Donbrothers is “people like the CG characters cuz CG cool!”
Also boost mk 2 and laser boost look really cool & I’m looking forward to seeing them in the show.

I didn't think we'd get another two-tier upgrade form after Command.

So from Magnum to Laser.

Wow, another two-tier upgrade, that's pretty cool. I hope that Tycoon, Na-Go, and Buffa get to use Boost Mk. II/Laser Boost Mk. II, but even though they all have their own Supporter Rider, I have a feeling that this will be a Geats exclusive, since we found out about Boost Mk. II through hacked sounds. And it seems unlikely that they'll get a turn, since Boost Mk. II has such a clear kitsune motif. Such a shame, too, since they've been pretty good about showing the other Riders using the Buckles, too.

As for the reveal of the other Supporter Riders, I think it works. Since they're from the future, it definitely gives off the impression that they're not of our time if they're capable of changing shape so drastically like that. And maybe it speaks more about Ziin and his fondness for Riders that he's the only one that remotely resembles a traditional Rider. Not to mention that them being support means that they don't need to necessarily take away any attention from the main four.

Shame that it doesn't seem like Boost Mk. II can be used with the Laser Raise Raiser by itself. Would've been interesting to see it be used as an alternative barrel.

Tbh I wouldn't count Command as a two-tier upgrade since it's basically utilizing all the functions it has on first use. You just have to build up to it like a meter and it's fully been accessible since the start. While you could argue it is, it's definitely not like the prior two-tier upgrades we've had.

Mk II and Laser though is definitely more in line with Shining/Assault -> Primitive/Elemental -> Barrid/Volcano where you have a singular item, with an add-on item that adds to it further.

As for the Supporter Riders... apparently it's their "Ideal Self" so you know. I think that works nicely for why they are the way they are. Also who knows how far the term Kamen Rider has gone in the future, to the point where I bet Xiin being the only humanoid one is purely because he's so enamored with Ace.

Ziin's like the guy who plays human characters in D&D. I can respect that. Maybe he wants to feel closer to the contemporary Riders by using their image, while the other sponsors want to assert how advanced they are by distancing themselves from humans through their physical appearance.

You say that like a grown man idealizing himself as a frog will be a normal everyday occurrence in the future.

so Fox and Wolf, Cat and Lion, Buffalo and Bull...I cant help but feel there is a reason why Tanuki's supporter is a Frog...
