Diffraction sword

File:Headstrong boxart.gif

He's actually three paces to the right.

Fighting Headstrong is hard enough - his armor's thicker than his mean streak is wide. But any Autobot unlucky or unwise enough to take him on not only has to deal with his formidable physical activities - he can't even see Headstrong while he's doing it, thanks to his diffraction sword. It bends light, making Headstrong appear to be where he ain't.
