Hmm, for my fursona he has ice powers so he usually just uses that, but it's to difficult to explain the awesomeness of his ice powers.
For real life there's this dude at this flea market who sells weaponry and if there was an attack going on there and I was at that stall I'd have over 3000 ways to kill any level of atttackers, one thing he has that is insanely epic is this huge thing, it has a wristband that attaches to a large twisted and insanely awesome shield-like thing that is in itself a powerful weapon because the entire thing is pretty much a blade and two large blades protruding from the front. Then it has many small needles attached and a shooting mechanism. Out of the 3000 ways to kill people from his stall about 320 ways resolve around that weapon. Also he has a huge display case of butterfly knives and army knives, then Japanese weapons (Katanas, Nunchaku, throwing stars, Shurikens, etc.), pirate weapons (Some are actually cutlasses with a gun built into it) then a whole bunch of other various blades, swords, shielding, projectiles, etc.
If there where a zombie invasion or something I'd go to that flea market, also there are food stalls and electronics stalls so I could survive quite a while.....
