Cyclonus and Heatseeker are perfect additions to this stellar lineup.
Heatseeker reuses the Strongarm and Ratchet transformation scheme but the mold is all his own with two great looking modes that have unique looks. My favourite part is how all the red from the robot mode gets centralized in vehicle mode along with the killer headsculpt. There is some really minutious detail there with an immaculate spec of blue paint to show his monocle and bring out his Kopaka Nuova look. He also has articulated feet, which Strongarm and Ratchet don't have.
Cyclonus really blew my mind though. He retains his super sleek altmode but does something no other Cyclonus toy has ever done: show no signs of a robot mode underneath. Through some brilliant engineering, he ends up hiding every detail from his torso in alt mode. Minus the arms, of course, and it is to bad that they don't end up more compact in alt mode. However, they do peg in securely and do blend in with the cybertronian nature of the vehicle.
A large chunk of the alt mode is folded very neatly on his back in robot mode, but it does en up giving him extra crests behind his helmet. You will see in the images that you can always pose him with that backpack lowered to get rid of that look.
Speaking of posing, he has far more articulation than most other legion classes in the line (probably the most articulation) with his transformation giving him knees and his arms being on ball joints like Legion Starscream and Windblade.
He has a great colour scheme too, with two purples alternating in different areas, one being that rich deep purple you only see in the sweetest grape drinks.
My main issue with him is the headsculpt. It just looks too cute and animated, like it belongs in a show for much younger kids. Comparing his headsculpt to Heatseeker would have you believe they were from completely different shows. But aside from that, he is awesome for me.
I am glad to welcome them both to my team of Decepticons!
