Ultra Act Mantle on Figuarts?
 

So I'm looking at the ultra act brother mantle on Amazon and I know ultra act is pretty close to figuarts. Would the mantle fit any? Thanks for any info

Its specifically designed to be plugged into the back of one of the various Ultra-Act Ultra Brothers (Taro, Seven, Ultraman, etc). It's designed to only work properly with them. You have to remove a plug built into their backs and physically plug a tab into them from the Mantle. So no it isn't really intended to be used with any other figures. Ultra-Acts are a bit larger than SHF's anyway so it would look a little silly.

And we have an Ultra-Act thread for any future questions you might have.
