sorry for the lack of activity, there is so many things I want to do but I can't cuz lacking of time (including making a custom of this design), anyway there is the info:
"Two Heads" are man-made Transformers which resemble Shockwave with an extra head.
Several Two Heads were built by KSI. After Galvatron took over KSI, they were among the forces he sent to capture the Seed in Hong Kong in order to cyberform the Earth. Hound shot one of them in the face with his cigar, and another was taken out when Optimus Prime set off Lockdown's grenade to force the Decepticons to retreat.
