1. Numchucks...
A friend of mine, when we were playing Star Wars RPG became convinced that light-nunchucks would be the ultimate weapon.
Now, it's not as studly as Tom Sellick, but he is a ninja; several times British Martial Arts Weapons champion and one of the few people in Britain licensed to teach nunchucks, so he knows what he's talking about. Anyway, this sounded about as stupid as most of his ideas, so we decided to set up a challenge: He has a pair of nunchucks mostly covered in boot polish, to represent the blades, and someone pokes him with a broom handle, similarly covered in bootblack, and we see how much of the polish makes its way onto his person. It took many months to convince him to take part in our scientific experiment.
But, anyway, the moral of the story is that lightsabres are cool, and nunchucks are cool, but light-nunchucks are really, really stupid.
#5 Whatever the throwing star with knives thing from Krull was called. As a kid, I just thought that thing was too cool for words.
It was called the Glaive. Which is confusing, because a
glaive is a type of polearm.
#4: USS Defiant (Deep Space Nine).
If you're going to go for Federation starships, then the
USS Prometheus has to win. You think you're fighting just one ship, and then it splits up into three, and you're surrounded!
OK, best weapons ever dreamed of, in no particular order:
Excalibur. Not only was it the most powerful magic item in the world, but it also conferred kingship on its owner. What's not to like about that?
HMS Habbakuk. During WWII, the British started building a destroyer half again as large as any other ship in the world. What makes it fifteen varieties of awesome is that it was made of
ice. Well, pykrete, which was a sawdust suspended in ice. It was never completed (the Admiralty ended up deciding that their resources should go to more traditional projects), but what was made of it to 20 years to melt.
Micro black holes. Used at least three times in Niven's
Known Space series (
The Hole Man,
The Soft Weapon and
Borderlands of Sol). In one case it was used to disable space ships (through a quirk of Known Space physics), so they can be robbed, and then all the pesky physical evidence just gets fed into black hole...
The tornado grenades from
Mystery Men. 100% effective, 100% non-lethal. Maybe the blame-thrower, from the same source, too.
Laughter. "Power, money, persuasion, supplication, persecution -- these can lift at a colossal humbug -- push it a little -- weaken it a little over the course of a century; but only laughter can blow it to rags and atoms at a blast. Against the assault of laughter nothing can stand." -- Mr Mark Twain.
