What are your favourite Sci-fi melee weapons?

Anybody already say lightsabers?

 

Plasma whips

 

one of my personal fav's from demon's souls, the large sword of moonlight, in other words, the moonlight great sword

you can easily turn this into a sci-fi weapon in that it'd run on battery power and it's made of pure energy(instead of moonlight because this is sci-fi, but then again i see either way working out fine)

 

I'd like something with this sort of design:

 

Something along the lines of Djinn (AKA:your generic flaming sword) :

 

No one has even considered that yet. Not even george lucas.

 

Unconventional weapons: A shield, a boomerang shield at that. Both offensive and defensive. Comes in a variety of styles.

 

hey, i didnt feel like reading everything to see

 

*...WooooMMwwoOOMmmWOOOMMwoommM* I don't even know what you're talking about *WHHHOOOOOMMMMwooommMWOooomm...*

 

I'd like a pair of gloves or even a full suit with which one could absorb the impact of blows and send it back at the attacker.
Other than that, maybe some sort of proper laser blade that doesn't so much end as simply cease to be focused enough to deal damage.

 

Compared to Western blades, Katanas are godly.
Katanas are made for cutting, and they are quite effective at such.
Longswords/Broadswords were made to crush your opponent's armor and bones, preventing movement, leaving them open to stabbing them with a knife/dagger in the weakspots of their armor.

I could also argue that the longsword/scimitar didn't save their respective regions from themselves either

 

A laser whip would be cool.

 

What is this, Deadliest Warrior?

 

No this is Patrick Mythbusters

 

Really would love to enter that contest!

 

Looks like:


Regardless, we need these:

 

I did a quick search and didn't see anyone mentioning it, so I'll throw in the beam katana from "No More Heroes"

/me Copy-Pastes any weapon from Fallout.

Power-Fists!

 

I would like some kind of large glove you put on your hand, that gives you weapons like this, in the mega man battle network games.
(preferably the blades)

 

The only thing I'd like to see that hasn't been said already (I think...)
