I second Roadblock V4, Sub-Viper, Snake Eyes V26 and Shock Viper.
I feel the same about another bunch too. Some because of the sculpt, but mostly due to the colors.

Actually more because of a personal color preference. I like V1 a lot too, but the green on his torso and knee pads/boots never matched on all the V1's I got through the years. Same thing goes for the skin colored sleeves + collar and the squares on the gloves.

Duke V4 looks more imposing than V1, who's smile is a bit too friendly IMO. I do like V1 because of the resemblance to the cartoon + comic, but V4 is extra realistic.

I prefer this version over V1, because of the camo scheme and that camo looks much more like the original card art.

Only compared to Range Viper V1. I only would've painted the eyes black.

Because she's visually more interesting.

Better colors than V2.

I really love the V1 as a figure, awesome accessories. V1 doesn't fit in with the IG ranks enough though, color wise. V2 became a Cobra figure, I like the jungle theme. Would've preferred the helmet done in brown.

Compared to Flak-Viper, since Nullifier V2 had absolutely nothing to do with Nullifier V1. Awesome color scheme, it's one of my favorite troops.

Compared to Mega-Viper, this is just
I'm still in doubt about Lifeline V4 compared to V1.
