Telford, here's a link to a list of subatomic particles:
http://en.wikipedia.org/wiki/List_of_particles
Just append a particle name with the word "beam", and you have an exotic weapon that would be the envy of any self-respecting galactic despot.
Kaluza-Klein Cannon - Based on the
Dilaton particle. Causes the strong and weak nuclear and the electromagnetic forces of the target to bleed into the other seven dimensions of spacetime, thereby reducing the target into a plasmonic goo.
Fracton Beam - The name of this weapon implies at first glance that it causes the target to fracture into a million pieces, but nothing could be further from the truth. The Fracton is a particle that induces the enforcement of
fractal rigidity, not
fracturing. Then and only then, once rigid, the target fractures into a million pieces.
Majoron Beam - Yeah, find the hidden word in that one. This weapon inhibits the mediation of neutrino mass violation, which causes the billions of neutrinos passing through the target to hit with the impact of bullets. This weapon is ineffective without a neutrino source (like a simple star) nearby.
Neutralino Beam - This weapon doesn't just neutralize your target. It
Neutralino-izes your target. You can see, of course, how much more effective that would be.
Omega Meson Beam - This weapon works best because, you know: Omega.
Exciton Beam - Uh, you can come up with your own theory of operation on this one.
Slepton Beam - I'm thinking this weapon renders the target craving for a cigarette.
