The best Bionicle weapon ...

[YoYoFantaFanta]

There are some really great ones, like Mata Nui's sword (I made it in silver and put it on the canister set instead of his Thornax launcher), Hewkii Mahri's Aqua Warblade, Phantoka Lewa's Air Saber, Piraka weapons, Inika weapons, Onewa's Proto Pitons, Matau's Aero Slicers, etc.

 

Best launchers IMO were Midak Skyblaster, Tridax Pod, and Thornax Launcher.

[Kanakalackin]

I wasn't overly-fond of the Tridax pods. They were great "bombs", but you couldn't really get much accuracy out of them.

The Nynrah Ghostblaster is my favorite projectile weapon. If used right, they could shoot pretty far, and the design was also good.

 

As for a specific piece, my favorite has to be Vahki Vorzakh's eraser staffs, they just look so cool.

[Kanakalackin]

Oh, we can do non-firing weapons!

 

My favorite non-firing weapon had to be Gadunka's head. One bite and half a baraki would be gone!

[Chro]

Mahri Jaller's sword. You never seem to see it in MOCs, even though it's a really cool sword.

Never see it in MOCs!? I see / use that all the time... XD

Does his face count as a weapon? LOL.

 

 

In-story... that's hard to pick. In set form, I like the Piraka's weapons, especially Thok's ice gun.

[Lachanu]

The weapons of the 2005 titans.

[ShadowVezon]

My favourites were the thornax launcher and Hakann's gun.

Projectle (that I own): Zamor Launcher. Yes admittedly the spheres do fell out, but a simple bohrok shield on the top and Hey Presto! That ball doesn't fall out anymore! Levahk's shields were the best for this since you can easily reload it without taking it off

Projectile (that I do not own): The Exo-Toa's arm cannon, always wanted that launcher...

 

Non-Projectile (that I own): Hewkii's aqua-blade blade. So many MOCing potentials for this excellent piece

 

Non-Projectile (that I do not own): Pridak's blades, oh the fun I could of had with those

[Just A Dot]

Mahri Jaller's sword. You never seem to see it in MOCs, even though it's a really cool sword.

 

I loved it with one of the parts of Mata Nui's shield used as a pummel. It looked so epic.

[Kazi the Matoran]

2001: Pohatu's feet and rock ball. I just thought that was so cool

2002: Again, Pohatu's feet, and his new Nuva claws

2003: Takanuva's staff

2004: the brown Vahki's blades, because they make the best shield ever

2005: Matau's blades, and Nokama's what'sits

2006: Riedak's saw/drill thing, Axonn's axe, and Nuparu's laser drill/gun thing

2007: Carapar's claw, Jaller's sword, Hahli's three-pronged blade

2008: Lewa's sword, Chirox's blades, Onua's shielded blaster and shield

 

That's it for me, really. My all-time favorite though, is Pohatu's feet and rock ball. He was the first set I got, and will likely be the last set I take apart, if or when that happens.

[Madara: Mangekyou Master]

Exo-Toa's arm cannon, Jahler Mahri's sword, Kopaka's Ice Sword, Lewa's Axe, etc. etc. I'd go on, but there have been a huge number of awesome weapons.
