Diffraction sword
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.
