Just unpacked him this past weekend and so far, I'm really loving it! Here's a quick summary of my thoughts on Prometheus: Alt modes on this set really shines, they captured the vehicles very well, and the vehicles are quite fun to play with. Transformation between modes was intuitive and fun, but I do have some complaints about the amount of panel-forming. It's not nearly as complex as FP Diesel, and is a lot more intuitive, but I can't help feeling there's more they could've done to better integrate the panels on the bots. Bot modes are very consistent throughout the set, and they all have the typical blocky TFC aesthetics. However, I personally would actually prefer them to have slightly different looks that more accurately reflects their characters. Last but not least, combined mode! He's very imposing in this mode, and with the exception of Groove, very G1 accurate. I do wish Streetwise's leg mode could be a bit more involved, but at least they added the missiles to bulk up his calves a bit more. He is far sturdier than any TFC combiners before. The back-and-forth ratchets are a little weak, but once you get it posed, it has no trouble holding the pose. The combined mode head also does look a lot better in person than in photos. I do like Guardia, too, and will definitely be getting him down the road.
