I'm not a fan of the Fossiliser concept (although credit to Hasbro for doing something new and innovative).

I did grab Wingfinger as I have a soft spot for pterosaurs; and I have Ractonite as Tha_Phantom gave it to me to "open" the gate on Fossilisers - which gives me something to compare her to, I suppose.

Yes, she's not that massive, but the beast mode wingspan is damn impressive. I love that beast mode!
