It's the same fabric figure as DX12, just missing some parts EMP gun etc.... and has new face plates.. BeastX says so..

please read the instructions included before attempting to move or remove parts..

some clothes cannot be removed without damaging it.. most Hottoys figures can remove the hand palms and head for alternate use..

depending on the clothes.. if its buttoned up.. you can remove and put them back on... but if it its stitched.. then its not meant to be removed...

pull out all the head hands and feet from the peg.. then slowly figure out from there..
if the jacket is tight fit.. try moving the arm to the back to slide the jackets out.. some slip it with the arm upwards to the head..

you can try search for hot toys wolverine reviews/tutorial.. that figure is meant to change clothes

You can strip everything from alfred and bruce... Except probably Alfred's fatsuit... which may require undoing some stitches.

HT has always been customiser friendly with their default clothed figures.... with some exceptions like Spidey

Apart from puny and fragile plastic "press/snap buttons".... dressing up a 1/6 Dolly is almost like dressing a full size human but with more "velcro"...

zips, clips, belts, pockets functions like a 1:1...

Apart from bringing the knees to the chest... Truetype male bodies pretty much can achieve human articulation (and beyond).

... frankly, dunno why you want to do that for. If you want to experiment just get a plain body to toy around with it before attempting to do it on an expensive one. I personally dun see this stuff as toys cause they don't come cheap. Secondly, I would advise you to google the type of 1/6 scale body, and available parts, while figure out how to work around with them (male - different body build, and female - different body build). You will then understand more before doing it to your expensive ones ...

... use a tweezer to adjust especially when your finger can be clumsy for tiny areas ... as for the head (connection) adjusting - use a hair dryer and blow hot air to the figure's connector to expand the plastic or rubber for easy detachment, attachment or adjustment ... careful when blowing hot air to plastic in order not to melt them ... just blow them a bit and test the movement -- bit by bit until it work ...
