I've been thinking about Toyguru's comment about a Filmation character replacing a 200X figure.
Now, of course, he could have meant Shadow Weaver.
But what if it's The Enchantress?
She's sort of an evil variant of The Sorceress.
She could use the Sorceress's top and skirt in dark pink. She could use BG Evil-Lyn's cape.
She could use Frosta's arms and legs... That is, of course, if Frosta is on the way
All she's need is a new head.
The other thing is that there is clearly a floating palace shown on the new map of Preternia.
It's likely either Kothos's palace, or The Enchantress's right?
