Doom Slayer: I have 3 of CT's Predacons and I'm eagerly awaiting the rest. Their articulation is good, you can get some good poses done. Firmament might be a bit more tricky, with the wings being a bit heavy. The quality of the materials used is very good. I have a tiny paint chip somewhere, but other than that, everything works great. Be aware that the transformation is quite a process, I would suggest using a video like EmGo's Just Transform It to help you.
