A great point I saw for the show is that each saga kind of sets up a different character for the secondary Rider role.

Episodes 1-11 is about Ryugen as Gaim's go-to guy and a slow look at the secretive side to his character. Episodes 12-19 have some focus in which Kaito becomes less of an enemy and more of an ally, but on temporary terms.

And while we're still in the 20-onward saga, there has been a lot of Takatora and a lot of explaining what his deal is and how he and Kota CAN get along, were nothing stopping them. By now, all of these guys have a story going on at high speed, which makes it exciting to see who takes the role first.

But going by "who appeared first" rules, technically Baron would definitely be classified as Gaim's true secondary, he meets the "gotta antagonize the hero" requirements as well and makes for GREAT contrast. And while Zangetsu appears an episode earlier, the official site doesn't really seem to officially acknowledge him until episode 4.

Plus like it's been said here, they definitely market Baron under that role a lot. It always struck me that whenever you see promotional material for the movies, you hardly see anyone besides Gaim and Baron, to the point I've had friends ask me "Are any of them even in the movie?"

I would have to go with Baron being Gaim's Secondary, instead of Micchy.

Gaim really doesn't fit in with the past several years of Rider formula so it's hard to say, but if you did try to shove it into that mold for comparison I'd say yes that Baron is the closest to the Secondary Rider trope.

I would say out of pure having to pick one Baron would be the secondary even though for a while it seemed Micchy was but I definitly think as far as the series goes story wise there isn't a true one Secondary rider since there are so many at this point.

guys there is a very simple answer to your question:
if you noticed over the last few years the drives for all secondary riders the driver voice had less of a japanese accent then the main rider's driver
in gaim's case its baron because his driver is the only one that fits the description i mentioned

[Tmclaughlin7]

I'd say Baron as well.

[MagnaKabutoX]

I would have to say Baron! Baron has many elements to a secondary rider than Michhy!! Let's be honest here, Ryugen would of been a secondary rider but due to the fact he betrayed Kota (even though he doesn't know about that)! I would have to say that Kaito is definitely the better choice for the secondary rider spot!! I know that most people that watches Gaim said this already but... I want Kota to realize that Michhy is betraying him. He was using the Genesis Drive and pretend to be Takatora. I guess Kaito is right he really needs to be stronger. When I mean "he" I mean Kota

In the beginning, I always found it weird that Baron was considered the secondary Rider and not Ryugen, because those were the days when Kouta and Micchy were straight up allies.

Now that Micchy has basically gone into straight up villain territory and Kaito has become more of a reluctant ally, I think Kaito has the best case, followed by Takatora, depending on how the rest of the story plays out.

[MagiRed]

Yeah, I'd love to see Baron as Gaim's new permanent ally...or even Takatora after he gives his brother a sound ass whooping as the original Zangetsu.

But you know who else I'd gladly accept? Bravo. I freaking love Bravo in this show, and I didn't think that I would when he made his debut.
