So one of the leaks is a G.I.Joe/Transformers crossover for SDCC. Have there been any rumors as to what this will be? I highly doubt it'll be an old G.I.Joe vehicle repainted like previous SDCC exclusives and I doubt it'll actually include a G.I.Joe figure since those have moved on to 6" scale. So it's pretty likely it'll be a Transformers figure, most likely from Earth Rise, repainted like a G.I.Joe vehicle. Problem is there's a real shortage of outright military vehicles in ER so far, just Megatron, Starscream (et al), and Doubledealer which would be kinda weird to use.
There is one that came to mind that could be neat, but I don't know if it would be different enough to warrant being made: The Defiant launch complex out of Sky Lynx. the Defiant has a crawler, a shuttle, and a base mode just like Sky Lynx. Only trade off is swapping a second shuttle for beast modes. The dino bird half would be in black and white and the lynx half can be darker blue with gray legs. Maybe change the gold parts silver.


(Incidentally, while looking for pics I cam across this neat custom
Lego Defiant Sky Lynx.)
There's also obvious things like proper green G2 Megatron (was he already leaked?) who debuted in the G.I.Joe comics, or mirroring the 2013 SDCC Jetfire and repaint Siege Jetfire as a Joe SkyStriker. If they do use Siege there's also Skytread, Impactor, and Hound.
There really aren't a ton of options, but I'd be really happy to see Sky Lynx as the Defiant happen.
