Does exactly what it says on the tin. What would you consider to be the best transformation designs? Here's my top ten below. Please note that I'm not a fan of Bayformers, but I'm sure some figures like Battle Blades Bumblebee would make the list. #10: Universe Cyclonus - Although not complicated, I would never have figured out that the nose of the jet folds into the robot's chest. Perfectly accurate in both modes and is "everything Galvatron is not", as fans say. #9: Animated Bumblebee - The fake car kibble on the chest had me guessing for a while, but it was really the way the functional trunk folds into it that impressed me. #8: Classics Mirage - Designed by the same guy who made Classics Bumblebee and credited with reigniting my passion in Transformers, it was Mirage that showed me how an updated vehicle mode can still transform into a cartoon-accurate robot. #7: G1 Blitzwing - A great transformation design for such an early figure. Blitzwing had two radically different alt modes and still managed to show less kibble than his Animated counterpart. #6 Animated Leader Bulkhead - I was genuinely surprised at how much fun this figure is to transform. Clearly a lot of thought had gone into concealing his six large wheels in robot mode. Also, his kibble becomes a chair! #5: Universe Prowl - Paint problems aside, this easy transformation not only allowed for a perfectly cartoon-accurate robot mode, but had shoulder missiles that were not separate accessories. That's awesome. #4: G2 Smokescreen - A childhood favourite. Smokescreen's transformation was elegant and remains a textbook example of just how articulate a Transformer can be. Until Classics Mirage came along, that is. #3: Animated Samurai Prowl - The samurai armour unfolds like origami and slips onto Prowl like a glove. Made all the more amazing by the fact that is was designed only after being featured in the show. #2: Masterpiece Optimus Prime - Had to make the list. The definitive Optimus Prime had two entirely different grilles and a Matrix compartment that slides into a LED switch. #1: RTS Wreck-Gar - What can I say? Asymmetrical limb design, convincing dirt bike mode, tailpipe axe, wheels faithfully on left limbs, and he can friggin' ride himself! No wonder people are army-building Wreck-Gar.
