Protoplasm stripper

Protoplasm strippers are Cybertronian technology from the Generation 2 portion of the Generation 1 continuity family.

The protoplasm stripper is a cylindrical device meant for separating the worthwhile parts of organic creatures from the rest. Evidently, it's something you'll see the Decepticons use a lot more than the Autobots. The only version shown so far was designed for humans of the size range as seen on Earth, but it's likely versions for other sizes exist as well.

Most of the protoplasm stripper is made of diaphanous material so it's user can keep an eye on the disassembly process.
