Yeah. If Evolto could have a semi-redemption arc and turn into an anti-hero even though he is so sadistic and twisted, Desast, a charming, funny, villain could more easily become a bit more heroic. Heck, he isn't even associated with the Megid anymore, he is only by himself. I can see him and the Sword of Logos Squad getting in at least an uneasy relationship if they were to need to fight some larger threat. Look at when Desast fought Ren Akamichi. They were fighting each other and were having a blast. They both loved the fact that they were fighting, together. So, I say that at least Ren Akamichi would love to be able to spar with Desast almost everyday. Heck, imagine if Desast got himself a Holy Sword that allows him to gain forms based upon the Alter Ride Books. I mean, they are under the category "Villain Rider", so there are some possibilities.

Seriously, that was just my inner MatPat from Game Theory, Film Theory, and Food Theory coming out. It was just me connecting the dots.

I guess I kind of sound like this.

I kinda prefer the idea of him retaining his sentience after being converted into a Wonder Ride Book, & able to use it to access his Rider form, either with Kurayami or with yet another repaint of the buckle that Calibur and Saikou use, only being able to use a sword after transforming in the latter case.

Just realized something that I don't think I've seen anyone pointed out about Saikou X-Swordman. Like I've seen people complain about and ask why he's so colorful, but it makes total sense that it's that way rather than just "it's based around comic books". You know what color light is? White. You know what happens when you shine white light through a prism? It turns into a rainbow.

So yea, it definitely makes sense that Saikou goes from "white" (if you consider the color of the Kin no Buki Gin no Buki WRB to be white with its clearish silvery blue) to "rainbow" with X-Swordman.

There's also something to be said about stained glass here. with each panel having its own color.

Yeah. Does anyone realize that the Main Story Announcement for "Kin no Buki, Gin no Buki", the translation of the name of the Story, and everything else about him represent "Gold and Silver"? And that he is all about Light. He is the Sword of LIGHT. Everything about him is Gold, Silver, And Light. And White Light is made up of all Colors in the Rainbow. So, him having such a colorful suit makes sense. Also, consider that the suit is called "Saikou Shadow". Shadows are wherever there is an absence of light. So, using Stained Glass to add color to shadows is pretty fitting.

Let me just stop right here and let's start speculating about what potential Wonder Ride Books we might see in the future.
So, looking at the current "Primitive Dragon", there will have to be something that can counter its berserker state. So, I say a Saint George based Wonder Ride Book could tame Primitive Dragon. Also, I have just realized that the previous time a Main Rider had a Berserker Form with a Dragon as part of it was Kamen Rider Build KeyDragon.

KeyDragon wasn't a berserker form, except for the Hazard variant, which I don't think was ever seen in-show because by the time Sento got the Hazard Trigger, it had already been established that anything dragon-themed went to Banjou.

And, uh... I don't want to be rude, but you've been saying your Saint George theory ever since Primitive Dragon was revealed, if not before. We get it. It is a neat idea, but bringing it up over and over won't make it any more likely to be true, or any more interesting than it was the first time.

Yeah. KeyDragon was a form that had a time limit because it was too strong for Sento to utilize. If used for too long it caused him damage.

KeyDragon got used briefly during Hazard, it was mostly a last resort against Evolt when he first showed up to possess Banjo.

Though by that point Sento had been using Hazard so much via the FullFull Bottle that the forms lasted fairly long before the automatic system started to kick in to where he had to switch to a FullFull form.

I guess I mistook "Berserker" with "Time Limited". Sorry.

I just thought of this, but what if there are two upgrades that let Touma control Primitive Dragon, and the first lets him use a dragon form(think Ryuki's Final Form Ride), while the second lets him control it more conventionally.
