Plasma net

Plasma nets are green energy-draining nets used by the Transformers. They aren't always effective.

Fiction

The Official Transformers: Generation 2 Annual

In order to finalize the capture of the dinosaur-minded Dinobots Snarl and Grimlock, Soundwave threw a plasma net over them. But it didn't work out as planned, because the net responded to their circuitry, causing a "negative ion feedback". Not only did it bring them back to consciousness, but it also fixed their minds and made them remember their identities as Autobots. The Dinobots!
