30MS SIS-D00 Nevarlia [Color A]

Neverlia uses Color A and the D type body (comparable to G), however her skin colors are more desaturated than other A colors.
Skin color inconsistency in the 30MS range is not uncommon, sometimes A looks more like B, while Neverlia has darker skin than B but has less color in it too.

Aesthetics:
There are crenelation details on the limbs and torso, which I'm personally not a fan of.
The body is fairly busty and uses black, dark purple, purple and lilac.
Neverlia has a lilac hair style with a movable back part and side strands.

Mechanics:
Neverlia's D type body uses updated engineering and has a wider range of torso movement and the hips are different (larger range, more fragile).

Equipment:
3 face plates, serious face, smiling with snaggletooth (same as box art), moaning face(!)
Armor - Horned tiara and thigh plates
4 pairs of hands - Holding, fists, grabby and peace fingers
1 Shield with small wings (or backpack)
1 Tail - Uses flexible cable
1 Trident
1 Backpack adapter and 3mm peg extender
Various purple ring parts

Conclusion:
If you want an 'evil girl' in the 30MS line, this is pretty much your only choice. Your only other choice would be Color C "Ilshana", I think.
The trident, tail and mechanical bat (shield/backpack or just on its own) will go well along with other 'evil' style builds, such as 30MF.

As mentioned, I don't really like the crenelations, but the hair is cool and despite the desaturated skin color, I like two of her faces. I'm not a fan of the snaggletooth, not because of the motif, but because the mouth isn't very nice, it's painted on and not very well.

I don't see the point in having her skin color on the torso, it may as well have been covered so you could fit any Color B or C with the body.

That being said, it's a good kit, an improvement on the older 30MS kits.
