Which ones would they be and why? Here's my list, from least to most important:
5. The Dark Knight utility belt
Who doesn't want Batman's utility belt? There have been many incarnations, but this one is my favorite. Most utility belts are limited to a bunch of pouches or cylinders, but on this one you can configure it to a variety of different canisters.
4. Luke's ROTJ lightsaber
To be honest, there aren't many lightsaber designs I like; most of them are too bulky and look very hard to use. This one actually looks usable. Plus, I'll never forget when I first saw the green blade. That was the coolest thing!
3. DL-44 blaster
Easily the most popular blaster in Star Wars. I love it's rugged look, and the scope is just awesome, suggesting a long range capability as well as close range.
2. The Dark Knight grappling gun
I freaking love this thing, especially how, instead of having an internal mechanism, the cable is wound up using the front of the utility belt. This made it more believable to me because, frankly, a lot of grappling guns are just ridiculous (I'm looking at you, Animated Series Batman). It also looks very comfortable to hold.
1. Deckard's gun
Anything that's powerful enough to take down a replicant is something to be feared. I would feel like such a boss wielding this, and would be terrified on the other end of it! I love the design, especially the bolt-action mechanism and dual triggers. They make no sense, but look SO cool! I also love how it uses real bullets instead of being a laser gun, something not very common in futuristic weaponry. And, like the Dark Knight grappling gun, it looks very comfortable to hold. Why does Harrison Ford always get the best guns?
Those are mine, now what are yours?
