As requested...
Here's Henri Ducard, a.k.a. R'as al Ghul in his ninja gear.
This one needs a bit of touching up with paint on the sword and a bit on the headsculpt. The whole figure, including the headsculpt, is one of Ironcrosshunter's figures. He still sells the unpainted headsculpt on Ebay.
The joints are really weak, so one of these days I'm going to have to disrobe him and tighten up the body. Until then, he's on the stand (the only one in my collection who really needs it!).
Here's R'as al Ghul, in his birthday party outfit:
The headsculpt is the more common Ra's headsculpt that shows up for sale from time to time. I think one of the members of these boards might have sculpted it, but since I bought it secondhand, I can't be sure which. It's more angular and stylized, and has an older, wearier expression.
The suit is all bashed by me - black coat, black shirt, black tie, black pants, black shoes. Notice a pattern?
I've been keeping an eye out for some super-dark green velvet from which to make his scarf, but it's tough finding a fabric that's dark enough (in the movie, it literally looks black unless you freeze frame it). I also have issues with velvet, so if I find some, that will be an additional challenge
I've also got a mini jewel thing that might work to add to his tie - he looks like he's got some white jewel pin or something on his tie in the movie, but I need to double check.
I'm also working on the red ninja robes that Watanabe's R'as al Ghul wears, and a sculpt is on the way from an artist here. I've got all the fabric, just need to sew it together. So that'll be a third "R'as al Ghul," though in actuality it's a decoy!
If HT ever does release a R'as al Ghul, you can bet it'll be the black ninja gear outfit. It's much more visually interesting and unique. Plus, not only do they not like doing just normal, fancy suits, but they know they'll be able to sell more ninja gear sets because many will buy two in order to bash a Bruce Wayne ninja.
In fact, if we ever see any kind of release, I'd bet it'd just be Bruce in the ninja outfit. Then you've got the unique factor, plus a more iconic character, plus the opportunity to sell extras to those bashing custom R'as al Ghul's, PLUS no need to deal with likeness rights, since they already have Christian Bale's.
I mean, I'd love to see a release with a Bruce head, a Ra's head, a ninja outfit, and the black suit outfit, but it's just not going to happen. That's why I've got these customs.
