Thanks to Stompy for tipping me and GPS boy about Jetstorm/Jetfire. Thanks heaps, mate!
Played w/ Jetfire and Jetstorm today and I'm still mulling over it. Don't have them b/c Ibrokeplayed with Jaydisc's. Another ambitious toy. My initial impressions are Energon/Powerlinx but the link mechanism operating vertically rather than horizontally.
Jet mode:
They're identical but the legs kind of just sit there. You can get them very snug BUT the two hip pads that give it the sleek jet mode fall off way too easily. According to Jaydisc, Peaugh has said this is a commonplace problem so not easy to avoid. Thinking about it I suspect it might be possible to get it right once you acquaint yourself with the mold much like Classics 2.0 Prowl. I've yet to decide if I can be bothered opening in it. I like the cockpit, it can be opened and the lightpiping in the head comes out nicely in the cockpit. The wings aren't too flash. They're pretty short. Not perfect but okay.
Robot Mode
Very nice. I like the articulation and the sculpts. Very nice. No hip articulation but it didn't bother me.
Combined Robot Mode
If you agree with Golden Phoenix (or Anorexia personified if u prefer) that Marvel Crossovers Venom is ugly from behind, this Safeguard is an absolute mess. Really destroys the figure for me. It adds balance problems to the toy which can be navigated by bringing them closer to spider-like arms. But the spider-like arms at the back don't make sense given this is a jetmode/elemental type bot. I particularly like the concealing of the heads in going from individual robot mode to combined robot mode. Very nice. The head has no articulation which was disappointing as it takes displayability out a lot. There's also a very lovely extra height gimmick in one leg of each robot to give the combiner an extra cm or so.
Combined Jet Mode
Why did they even bother? Nuff said.
Overall
I liked it. I'm uhmming and ahhing over it I guess b/c the primary gimmick of this set (the combining) doesn't execute as well as I would've liked. A lot of originality here in the design though and I guess that makes it a win in my book. It's much like Energon I suspect. The first few powerlinx figures were cool b/c the concept was new but if Hasbro persist with this level of combining again, it'd become tiresome and downright uninteresting.
