Shrink Gun

The Shrink Gun is a prototype tech piece that works with Darren Cross's replication of Pym Particles. Although it was originally meant to shrink organic, it instead kills them turning it into a tiny puddle of protein substance.

Darren Cross still found a use for this gun, to kill sneakily business rivals. After Cross perfectioned his version of Pym Particles, he didn't use it again, probably because he thought of it as a failed experiment, or probably because it was too dangerous or impractical for another reason.
