I want to put this figure's head on something else, but I don't know of anything in a similar scale that has the same kind of ball-jointed head/neck. This is the best I can do to convey it's size. What would work? I can put her on some Gundam kits, but their joints are a bit small so it's not a great fit. Is there anything sorta like CORPS that has this type of neck? Any help will be much appreciated!
G.I. Joe, Marvel Universe/Infinite, and Star Wars are all close to that size and use similar neck/head joints.
Don't look at them in the faces.
Well maybe, Black Widow is okay. But no, don't look them in the face.
Black Widow (MU and Avengers movie versions)
Baroness, Scarlett, Lady Jaye, Jinx (G.I. Joe)
Wasp, Aurora, Scarlet Witch, X-23, She-Hulk, etc. (MU).
There's also the Star Wars figures. I think they use the same basic neck ball joint.
Baroness and Lady Jaye are together in a 2-pack from the GI Joe 50th Anniversary series. Wave 1 has shoddy paintwork as you can see.
Black Widow in the middle is from Avengers Assemble line from 2013~2014. Best headsculpt of the character but the body is largely reused from the Avengers movie black widow figure.
