KR Drive could use a dark rider. Maybe a viral KR Drive.

Anyway I hope Freeze Roidmude won't be killed off very early because he is the one who responsible for Global Freeze, indirectly injure Akira Hayase and I heard he have connection with Shinnosuke's Father's Mysterious Death.

He could gain more evolved form than his Freeze Form, Maybe he could combined Heart, Brain and possibly Medic into 1 unstoppable Killing Machine. Who know? :)

What about the Promised Number? Is it still involved?

I can imagine they will keep 001, he feels a lot like final boss material or maybe they could combine to make a super Roidmude.

For example Tomari: " They morphed together."
Krim: " Be careful Shinnosuke, this could be dangerous."
Tomari: " Yeah, so what Rodimude are you now then?
Super Roidmude: "We are the combination of two of the Roidmude 003 and 001, we are Advanced commander Roidmude Brain-Freeze."

Lel.

... That pun...

I am glad the both of you found it amusing :)

In fact that made me want to write another one so here is this

Super Roidmude: " We the fusion of Roidmude commanders 002 and 003, we are he..."
Medic: "I knew you were up to something Brain."
Untransforms
Brain: "If you do not mind Medic, we are in the middle of an important experiment that may allows us the power to defeat kamen rider.
Medic: " Oh I see what you are doing Brain, you are just trying to get Heart for yourself"
Brain: " Oh perish the thought, Medic.
Heart: "My good friends calm down, aren't we all colleagues together, if you want Medic we can all combine together.
Brain and Medic: " No not with her/him"

Tomari : Oi Belt-san, what on earth is going on there, it seems like some sort of feud ?"
Krim: "From my experience this is what they call a lovers spat, but I will explain more about that when you are more ready for this type of talk.
Tomari: " Hah, what is that supposed to mean, oh whatever, I am done thinking about this.

I just had an idea...what if chase is based off of Shinnousuke's dad? Idk lol

Probably not but it can be quite the funny idea.

Speaking of which
Chase " By the way Tomari, I am actually your father."
Tomari " What, you have to be kidding?
Krim " It is true actually, I have know this entire time and not told you."
Tomari " You know, I am just not thinking on this more, I need some fresh air, I am going out."

Gou " So did he actually fall for it? "
Krim " Indeed, I must say it is quite fun to play pranks everynow and then. "
Gou " It's thanks to this guy here the prank worked.... I still hate you Chase.
Chase " Likewise"

PLEASE PPL! This is no time to be funny!
