#1: ER Sky Lynx. Even went so far as to make a full-blown space-themed photoshoot with him, which you can see here:

#2: Netflix Soundwave, with Ravage and Laserbeak. I don't think I need to say much more.
#3: ER Scorponok. Just may be the best of the Titan-sized figures so far.
#4: ER Optimus Prime, and by extension, "Alternate Universe" (dead) Optimus Prime. Ended up having a LOT of fun re-creating his death scene, and building a coffin for the "dead" Prime.

#5: Netflix Bumblebee. Aside from the obvious appeal of having a poseable 'Bee that's a classic VW Beetle again, it's more special to me because it was a Christmas gift.
