Null-ray
- The null-ray is a weapon from the Generation 1 continuity family
One of Starscream's signature weapons, the null-ray is capable of stopping any electircal device with one shot, be it human or Transformer.
Except Megatron. All a blast from the null-ray does is make him angry. It doesn't work on the Dinobots either, but they were already pissed at Screamer.

After causing a tidal wave at Sherman Dam, Megatron ordered Starscream to shoot three of the generators with blasts from the null-ray as part of their efforts to make Energon cubes. Why they would need the generators to stop working is beyond our understanding, but Megatron's schemes always have layers within them. More Than Meets the Eye, Part 2
After being discovered by Bumblebee, Starscream shot him with the null-ray, allowing the Decepticons to modify his memory circuits to lead the Autobots into a trap. Transport to Oblivion
