Indeed. The new DX Kiwami Key will unlock the secondary faceplate on the Kachidoki Lock Seed. You won't need a new Kachi.

and even if you missed out on Kachidoki there is a DX Kachidoki and Kiwami set coming out around the same time as Kiwami's lockseed.

Huh I did not like it when it was first shown to be a cast-off armour but the toy reveal has me digging it, the toy captures the look and gimmick perfectly and I love the Kiwami design, my only hope is that it has the ability to use Kachidoki Arms so i can display him with the best version for the what 3 seconds it would be in that form. on the other hand i might never use it so i could take a crack at painting it to look a bit better, this also reminds me of the Gaim that came with Watermelon a mostly unpainted only focused on the gimmick version of a prior toy.

Hmm. This looks pretty cool. Even if it's ripping off Kabuto so much :)

Feel free :lol

Guys I have the new saying.

PEEL OFF! CHANGE FRUIT MAN.

And a 2nd image has appeared!

It looks like this confirms there aren't indentations on the shoulders to attach other fruit Arms. And it doesn't appear the helmet section is NOT removable either as with the other figures. The visor isn't set back into the helmet like it is on figures which have the swap ability. So it's safe to say this toy doesn't have any of the usual change gimmicks. Then again based on this forms premise, it shouldn't anyway.

It's too bad it isn't compatible with the previous Arms. It makes sense that it wouldn't be since that's not the point of Kiwami, but the armor swap gimmick is what made the line fun. Makes this an easy pass for me.

Well, pretty cool gimmick for the figure at least! I guess Kiwami arms isn't really an Arms Change and is just it's own thing.
