Kerrigan, Queen of Blades from the Heroes of the Storm Cute But Deadly collection.
She is very topheavy, and her raised foot actually has a peg that sticks into the purple mini-base. For stability, it may be best to superglue those two pieces together, as the foot tends to pull free even when the figure is just standing.
Unlike Sylvanas, Kerrigan does not have any poseable parts. Her “wings” are surprisingly sturdy though!
