As some thought, the Shockwave and Longarm toys in Animated (seen at SDCC presentation) are indeed the same toy. The packaging proudly promotes a toy with 4 modes, even if the two robot modes are not too different from each other (nor are the two alt-modes either).

At least we have another double-spy toy to go with Punch and Doubledealer.
