Despite hailing from the end of Generation 1, Overlord is not a character I'd been particularly aware of until comparatively recently, since I'd 'grown out' of collecting TransFormers by the time he arrived in the UK. My first experience of him in anything like his original form was via the Titans Return version, which was a little too cut-down in terms of functionality versus the G1 original. Improved articulation only gets you so far, after all.
However, I believe that my first experience of the character was via this strange BotCon exclusive repaint of the Revenge of the Fallen/N.E.S.T. Global Alliance Bludgeon, itself a reimagining of a G1 Pretender. While that character wasn't the best fit for a movie offshoot toyline, the figure was great... and I might have been in the market for some of the other repaints if they weren't all so hard to obtain, to one degree or another.
I missed out on this figure around the time of BotCon 2012, but eventually found one reasonably priced on eBay, and took the plunge, even though a tank-only version of the character is already missing half of what made the original so interesting. How does it compare, though..?
