Kreon Air Raid. Clip-on and plug-in wings, along with the neat little clip-on SSRs, the 1x1 Round w/Vert. Bar, and the 1x1 Plate w/Double Bars (closed ends) are all cool pieces. You may be able to use the helmet as the nose cone to some sort of giant rocket.
Kreon Firestrike. Yeah, this one's a little blurry. The black piece
2nd from the left in the middle row is a 1x1 Round w/Vert. Bar.
Kreon Silverbolt. That 1x1x2 Cone piece is pretty interesting. And, as always, I like the Kreon bazooka piece.
Kreon Skydive. The usual suspects here.
Parts. I'm having fun experimenting with those Black and Grey pieces that are used to make the Combiner form.
Can you build a frame, or frames, right away? Yes. The Kreons are good for 4P scale. (+5)
Is it below, at, or above the golden ratio? Above. (-10) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? No. (-5)
Score: B- (-5). This one could be a good army maker at 4P scale. Especially if you find it at $0.07 per piece like I did.
