The Parlamentarian

No idea what is it, but it's made up yet more powerful than anything

On the topic of bigass nonsense swords, I'm a big fan of Soul Edge (mostly for Soul Calibur 2 nostalgia reasons)

"Favorite" is a strong word, but I really like the caber from Beastmaster.

It looks like something impractical that some artist would draw, but then it turns out it's pretty similar to throwing weapons that certain African tribes used

In the real one the purpose of the shape is to ensure that a sharp part of the weapon always hits your target, IDK if the movie prop would function that way but it certainly evokes the same feeling when I look at it.

The Buster Sword from FF7 is just what a santoku kitchen knife dreams about becoming when it grows up. Chopping onions will never be the same again once you slot in a Mega All materia.

I'd say any fictional iteration of Gáe Bulg because I fucking love mythical spears. I also really like the grotesqueness of the relic weapons in fire emblem three houses.

There are a lot of contenders, and I guess my favorite is going to depend on various different categories. But the first one that popped into mind just because I think it's really cool is Fromsoft's recurring moonlight sword. Started in King's Field and then carried on into the Souls series and even Armored Core has an equivalent.

I like it because it's a cool design and also has a cool effect. It's the full package, ya know?

I think maces need more love. All the movie and game heroes use swords but a mace would fuck somebody up. Maybe a flail if we want to get fancy.

the kirkhammer from Bloodborne is one of my favorites! pretty much all of the weapons in Bloodborne are all-around fantastic but the kirkhammer specifically is the one I had the most fun with and I love it's design

Fukken lightsabers, man

The Ashbringer from WoW

The Gonne.

Guild Wars 1 had a lot of unique and weird weapons but the Fiery Dragon Sword is one of those rule of cool weapons even though it makes no sense practically.

I'm partial to absolutely ridiculous weapons like a coffin that shoots bullets or beating someone to a pulp with a literal full sized cross that jesus would've carried. The most unwieldy impractical things possible.

i liked the soul stealing chaos runesword from the Elric series

I like keyblades because they're customizable and beating the shit out of characters like Sephiroth and literal titans with a giant key is just funny.

The glaive from Krull

Such a goofy thing

Roland's revolvers from The Dark Tower. Forged from the melted steel of Excalibur. I really hope the next adaptation they're doing will be good

“Here is my sword,” said Intra. “Your semiotics cannot contain it. Its blade is made of gloaming steel, look how it whispers!”

“But Lord Intra,” said the assembled, “You have no sword!”

“So it is,” said Intra.

side note but I really enjoyed how the character raelza in this handyman saitou anime has a similar sword to Guts's but it shows a slot on it/her armor that she locks it onto and it's like, nice, they actually show that instead of the sword just being stuck to their back like a magnet

Bleach had (has? I hear it's back on again now) some really great ones. Basically every weapon has multiple forms where it gets cooler and cooler, often culminating in a battlefield filling sentient monster.

Abarai Renji has Zabimaru, a hooked whip sword that transforms into a flying bone dragon.

Kuchiki Byakuya has Senbonzakura, which looks just like a normal katana but its special form scatters into thousands of tiny blades which are only visible as cherry blossom petals blowing in the wind from the light glinting off them.

Ichigo, since he's the protagonist, has an extra special sword that gets smaller instead of bigger in its special form, which concentrates his power and makes him extremely fast and strong. It's normally like Cloud's sword but shrinks down to become like Sephiroth's but all black.

I kinda liked the Galaxy Eater from the 50th anniversary of Doctor Who. The implication was that it had the capacity to erase whole galaxies from time, but it never got used it because it developed a conscious. It judged anyone who tried, manipulating them psychologically and temporally.
