Faaaaaaaaaak..... I didn't even realize this was an SDCC exclusive (or, at least, that it debuted at Comic-Con)... But either way, thanks to Amy from Lulubell, I got me an EMPEROR LARVAGON!!! http://www.lulubelltoys.com/velocitron-larvagon.html
Thanks guys! Looks like there has been another new mutation taking place over the last few weeks with Larvagon. Almost like he's been merging with another type of monster... I should be able to get you some photographic evidence by next week!
