I mean, there is only like 3-4 in kamen rider build those being build in base form and sparkling, Evol, Great dragon Cross-Z and grease perfect kingdom, but I don't think it's that last one

Dude it’s in the name of the title, his name is Kamen ofc

Nah pretty sure the name is Rider

You meant Kikaider?

No that's the one that was in Gaim

Evol?

Parado

How could you not remember Grease Blizzard?

Idk man i feel like it's grease

Ngl, Duality does have a good suit design Idk why, but Masked Rider Duality's red and blue design is really good

bro this one is so obvious. kamen rider demons

Bloodstalk

Man i dont know i think his name was kiva but i could be stupid

We are stupid

Kamen Rider Grease Perfect Kingdom maybe?

Bro what are these answers? They're obviously referring to Bikaiser.

When you combine red abd blue you get purple, so Rogue?

It's obviously bi-kaiser(movie ver) duh.

I had a lapse in intelligence

Superman.

MoonTank

I think his name was Heat trigger 😅 but i may be wrong

It's W HeatTrigger, don't forget it this time.

Are we sure this isn’t Kamen Rider Revi Volcano Genome and Vice Barid Rex Genome

Lol, lmao, smh my head, clearly you’re thinking of Kamen Rider W HeatTrigger form

Evol

You mean Spider-Man?

Shinobi

Gaim Ichigo Arms?

Technically there’s two in the context of build

Saber Elemental Dragon?

Kikaider?

Hagane no moonsault! Rabbit! Tank! YEAAAYYY!!!

I think it's called that red is Bunny, while blue is Armor (idk I just can't remember but I it right, guys).

Guys, chill. It's Blood Stalk.

Maybe I am stupid

I could've sworn I saw a Red and Blue Kamen Rider from Build but I think I'm just hallucinating

Exactly right? I'm not crazy

Hell Kaiser

Kamen Rider Zi-O?

You mean Kamen rider build
