Blowout

“Blowout: Defective Model”

Over the years, Hasbro has used several Megatron toys as the basis for new characters (with varying degrees of redecoing). The most well-known of these is Megaplex, the winged robot in the upper left. He was released in the Machine Wars line, and his packaging bio explained that he was Megatron's "decoy." This idea actually goes back to the heyday of Generation 1, when small monochrome rubber figures of various Transformers were included with the standard toys as a promotion. They were also called "decoys," and naturally there was one of Megatron.

Rounding out the group is Archforce from Generation 2, who looks nearly identical to Hero Megatron because he was simply the European release of that toy. His packaging bio was basically Megatron-ish, but no acknowledgement was given for his uncanny resemblance. G2 also gave us Blowout, whose toy is just Go-Bot Megatron cast in translucent plastic. This resemblance was likewise left unexplained, though his gun's ability to "draw energy from distant stars" sounds a bit like Megatron's ability to "connect [his] cannon interdimensionally with a black hole, where it can draw on anti-matter as its power source." Thing is... Blowout is an Autobot!

My own explanation for all this is that these characters are indeed Megatron clones, but for some reason Blowout's programming went awry, and he wants to switch sides.

Now... knowing all that, bonus points to anyone who can name the three Autobots he's headed towards! Well! ~fourth-heir figured that one out pretty quickly. Good job! The three Autobots are, from top to bottom, Thunder Clash, G2 Sureshot, and Firecracker... all Optimus Prime doppelgangers. I don't think they're "decoys," since that doesn't seem like Optimus's style, but maybe there's been a Primus apotheosis outbreak.
