>>7098588Here we have Shockwave in robot mode, you can see the big cannon as his left arm, but if you look under his armpit you see the shoulder piece for what becomes the left front leg in tank mode (which keeps the same shoulder design as his normal arm). As the transformation involves spinning that arm back and swapping what would be the leg upwards, it seems that it would be possible to give Shockwave a second left arm in bot mode.
