Ganbarizing honestly has a lot of cool original finishers for the Riders that I wish sometimes were in the show.

Like there's a finisher for Valkyrie where she rushes towards the enemy, kicks off them into the air, spins rapidly while dropping before slamming her leg directly into their head.

Other highlights for me include Build KeyDragon going Kingdom Heart's and summoning a keyhole portal to stab the opponent into it. The portal appears above Build who proceeds to roundhouse kick the fallen opponent with a boot full of flames.

And then one of the more hilarious ones for me, Zi-O Decade Armor throwing a Rider Card at the opponent and summoning Final Attack Ride Cards all over which he proceeds to zig zag through while kicking out before kicking against the enemy.

I almost prefer these colors for Cross Saber

Alternate reality where Saber gained the power of his allies by cutting them down and being washed in their blood.

I like Cross Saber's arcane blue color, but that sanguine red version looks like it could be good for a Kamen Rider Dark Saber, like how Dark Kiva was a repaint of Emperor. I would have called it Sabre with French "re" but I think that sounds too similar to Sabela.

It's also the spelling in British English, so it would work as a dark counterpart with the whole words and book theme of the series.

The blue color scheme for Xross Saber makes sense though. Fire goes from red to blue as temperature rises, no?

Fire's naturally orange, unless you add a certain chemical compound to change its color to red.

Well, sure but the blue on Xross Saber isn't supposed to be fire, it's supposed to be space/the cosmos.

The "Fire" aspect on Xross Saber is technically represented by all the stars scattered around the suit, as fire at it's hottest is an eye-searing white.

Yes, I should have said reddish. My bad. :lolol

I'd say it works both ways but what you said has more weight than mine with the flame color transition thing being more trivial. But because of his status as the fencer of fire I think it still justifies repainting him from a hot hue to what we tend to consider a "cooler" hue.
