It's a weird thing.
Anakin only has Sith Eyes when he's killing the separatist leaders(Or when he's burned). Neither of those times is he anywhere near the lava robot, lol.
To my mind, the normal version should have had the lava base, and a swap out Sith Eyes sculpt. Even if they made is a deluxe version.
Either that, or the Sith version needs a head with normal eyes.
I'm not complaining that HT made the decision they did. They *are* a business after all.
I have bought the normal version, and also the Sith one. I just like to have all the looks. And as most sellers are trying to get $100 for the base, and close to $150 for the sculpt, i would far rather have both figures, than buy the parts to have both looks.
