Most Powerful Sci-Fi Weapons?
date
newest »

In terms of raw power, I guess that nothing can beat the killer planet featured in STAR WAR: THE FORCE AWAKENS. As portable weapons go, however, the choice is a lot more diverse and, in a way, a bit disappointing. Too many SF movies and books use what amounts basically to souped-up assault rifles from today. The notable exceptions are from the STAR TREK series, with its phasers and disruptors that vaporize opponents.


On the large scale, the Virus Bombs and Cyclonic Torpedoes of the Exterminatus (Planet Killing) in the Warhammer 40k universe are about as powerful as things get, unless you want to count the weapons in various SF novels that cause a sun to go nova.

Whatever that thing was called in Jack L. Chalker's Well World series that forces the universe back to its neutral energy state. It literally destroys reality and once it becomes too large it is unstoppable even by the planet-sized computer that *controls* reality.

Are you thinking of the 'Ultimate Weapon' designed by the computer Hactar in Douglas Adams' Life, The Universe And Everything?

I'd forgotten that. Now I'm going to start shuddering when I watch cricket again.

I'm pretty sure I remember a multidimensional weapon of mass destruction as well but I can't remember from what.


Black holes in the center of the planet, always fun.
I always felt Vernor Vinge's 'Bobbles' were such an interesting way for a possibly 'peaceful' race to get rid of dangerous and troublesome planets.

With science fiction, I would always choose a lightsaber. With fantasy, I would always choose Excalibur.

Also because it's my current goal to poke and prod and dig around everything Brandon Sanderson related, I'll also suggest the most powerful weapon in his 'Cosmere' must be a whole 'Adonalsium', whatever that may turn out to be exactly. Or even two Adonalsiums!

In the same vein, I'd go with the Molecular Detachment Device from Ender's Game.

As did the transwarp drive in The Wounded Sky. Doc Smith had a lot of super-weapons, such as the Nega-sphere, which devoured planets. Let's not forget the Ultimate Nullifier, which was once used to destroy an entire universe. There was also a universe-hopping device I read about in a short story, which had the unfortunate side effect of consuming the universe it was leaving in order to get to the next one. And the psionic amplifier from World of Ptaavs which allowed the Slavers to order every living thing in the galaxy to die.

I don't want to get sucked down the rabbit hole. But I'm sure Tv tropes has a decent starting list of things even stronger.
Destroys multiple dimensions/realities/universes level
Destroys an entire universe < havn't seen anything posted above this yet.
Destroys an entire galaxy
Destroys a solar system
Blows up a planet
...
I'm pretty sure there are multiple in that top level in SF/F.

Crap. Good point.
Looks like TV Tropes classifies them all the way to Class Z as the worst (or best, depending on your perspective).
Lyndon Hardy's multi-dimensional destroying demon in Riddle of the Seven Realms (where his void-creating fire will destroy all dimensions that utilize that magic) and Stephen King's The Dark Tower (multiverse reset) are Class X-5.

Definitely the Starkiller Base from Star Wars: The Force Awakens. The reason for this is because not only is it stronger and larger than the Death Stars, but it also has a much longer range. The Death Stars could destroy only one planet with a single shot while Starkiller Base can destroy entire star systems at greater distances.
