For this 2019 version Hasbro used the helmet from the 2008 Darth Vader figure (it's only a 2-piece helmet, the face mask is glued-on or sculpted onto the dome and only the dome and collar can be taken apart), and they used the soft-goods robe from the 2010 Darth Vader figure (where the robe is removable, this wasn't the case in the 2008 version)
Unfortunately the soft-goods robe is made out of very thin material so that when the light shines on it you can see through it
The helmet closes the gap to the bottom part where the collar is quite well, and there isn't much of a gap, but it sits on top of the collar very loosely
Darth Vader has no balancing problems
