– Head, torso, butterfly joints, hands, boots and cape: Banshee (2023 X-Men 60th Ann. 3-pack)
– Arms, midsection, pelvis and legs: Prowler (2018 Lizard wave)

It's hard to designate a "base" figure since it's pretty much half Banshee and half Prowler. I chose Prowler since he's green plastic in the most places where paint rub would be a concern (e.g., knees, elbows, pelvis). The proportions for his sculpt are also fairly close to the new buck Banshee came on.

I pried open the torso and masked it off, along with the forearms and shins, then used a combination of Mr. Hobby and Tamiya acrylics to try and match the green (torso) and yellow (forearms and shins).

The color isn't exactly right since Banshee should sport a more vibrant "kelly" green, but this will do until Hasbro gets around to their own GSXM1 Banshee.
