In the same box from BigBadToyStore as Artfire was Prime Starquake and Dark Energon Wheeljack.  I keep internally calling it my Super Expensive Box of Entirely Redecoes, but I think that title's taken by BotCon each year.   Skyquake I had on preorder 'cuz, well, he's a tailender, so no guarantee he'll hit stores in great numbers.  Beast Hunters stuff is already coming out, so his time on the shelf is limited.  And I had Dark Energon Wheeljack on preorder 'cuz he's friggin' Slicer.  In fact, he had Decepticon faction symbol Reprolabels stickers on him in about thirty seconds, once I looked up on Transformers Wiki to see whether he had photos taken of him yet.

Because Skyquake has been dead in fiction for years (seriously, he showed up to die in the first episode of Transformers Prime's proper first season), I started to come up with a backstory for him.  He doesn't really have a present- or a future-story, so that's all he gets.  And, hey, look, he came in a box from BBTS with another guy based on a Europe-only release from the early Nineties.  That's right, he and Slicer are now super badass partners-in-evil.  In the past.  Before Skyquake got locked in a closet in a mountain on Earth.  Where Slicer is these days, I dunno.
