[Optimus Vader]

The pilots were always "sold separately" and the costs haven't changed since this was first announced. The pilots are "sold separately," but will be up for sale at the same time as it's corresponding lion, so they will ship together.

I have no idea why they're sold seperately though. I guess there could be people who would only want the figures and not the lions? ..because I believe you do need the key to transform them. I'm sure there are ways around the key thing, but that's how it's supposed to work.
