I have the DC Direct Mera currently among my display figures but she's a bit too tall and her articulation is a little limited. I recently got an ML Nakia on sale. I didn't have any plans for it, I just thought it was a cool figure with good armored costume design so I bought it and just stored it in case I need it for something. While working on a different custom it dawned on me that Nakia's costume is mostly green. And that led me to put this together since I already had all the parts. Pretty simple custom, swapping in ML Eternals Sersi torso just to change the look, repainting some parts of Nakia's costume and filling in the unpainted groove lines that Hasbro didn't bother to do. I still really like the DC Direct Mera so I don't know if this will replace her for display. Maybe just temporarily.
