Parademon Gun (Earth-6531)

"Forty-seven known alien objects hit the ground after the portal closed above Manhattan. All dormant, all dead. Except this one."

- - Agent Jasper Sitwell

The Parademon Gun is a direct-energy gun and the most common weapon of all of Darkseid's Parademon armies.

History
When the Parademons invaded Earth for a second time, this time under the command of Loki, the artificial warriors used these weapons as their primary offense.

After the Parademon Command Center was destroyed by Iron Man, all Parademons were killed, and their weapons left behind. Many groups sought these weapons, and their technology in general, in numerous attempts to create their own and reverse-engineer it.
