This incarnation of Shockwave has the ability to change his body, using this power to assume the guise of Longarm in order to creep up the Autobot ranks and serve Megatron incognito. To further his guise, changing his actual G1 color scheme to a grey pattern, Shockwave provides his Longarm guise with an alt-mode like that of a burly rough terrain crane.  Shockwave features four distinct modes; his normal robot mode and a shorter, stockier Longarm robot mode, each with its own alternate mode - a Cybertronian tank and crane, respectively. His faction insignia can be flipped between Autobot and Decepticon.
