As much as it sucks, it's how HT works and I don't see it ever changing, they simply never make a 2 in 1 set that has ever part to make both figures, you can make one or the other without buying extra bits, that's it.
Superman - 1 body for 2 heads and outfits
Two-Face - 1 body, 1 pair of pants, 1 shirt for 2 portraits
Marucs Wright - 1 body, 1 pair of paints, 1 shirt for 2 portraits
DX Joker - 1 body for two complete individual figures
The Joker was a real kick in the balls for collectors, all they needed to do was throw in a second body for a special, deluxe figure to make both of them and they didn't.
I guess I'm just used to the games, which is why I bought a second MMS117 T-800, in antipation that such a game will happen with T-800 where you'll get the Cyberdyne weapons, but you'll not get another clean portrait and outfit for the Cyberdyne scene.
Yeah it's Hot Toy's style unfortunately. The other example I can think of is the Resident Evil 5 STARS Chris figure, it came with a shirt that should have been included with the original, BSAA version of the figure.
I mean, i've just ordered Final Battle John Connor so i'm now on the hunt for the correct rifle! You never know if they are genuine mistakes though and that they are lucky enough a 2nd version of that character is coming out which they can include the accessory with.
