So, I stand corrected. The Authentics Bravo figures are a LOT bigger than Core class. I took shots of them next to several contemporary figures, and they are nearly as tall as Bumblebee/Bug Bite. I thought maybe they might be roughly the old Basic size, but they are even a little bigger than Energon Arcee, but slightly smaller than Cyberverse One-step Whirl. So, scale might be a little off, although maybe okay for Primal?
