Here are my Top 5

5 - RTS Wreck Gar
Great solid figure with a perfect 'dirt bike' alt mode - perfect for a JUNKion
The axe head should have been red though...

4 - Generations Wheeljack
I don't have this yet, but from what I've heard its an even better use of the Tracks mold. A pity they couldn't use the modern Stratos for this new mold.

3 - Generations Straxus
Yeah we all know him as Darkmount, but finally a figure for a memorable G1 Decepticon.

2 - United Scourge
A slightly better recolour of the Generations mold. He just looks better with the right eyes

And My number 1:

1 - Generations Blurr / Drift
I couldn't really separate them. I think this mold is better than the Sunstreaker/Sideswipe mold. I like guns + swords. The use of hilts/scabbards were perfect. Now if only a 3rd Party created a G1 style head for Blurr. I wonder how that would look????
I'm a Drift lover, not a hater. HOw can this mold not be appealing??

The next in line for a United/RTS/Generations future wave:
Now if only the end up making a proper G2 Jhiaxus figure......
