In terms of character's weapons in Deception, I don't really have a favorite because I almost never use weapons, only the two main fighting styles. If I had to pick though, I'd say Jade's is one of the most useful.
As for level weapons, I definitely have to go with the Quadspade in Liu Kang's Tomb. Whenever playing that level I always make sure to make use of this awesome weapon.

I like Ermac's weapon!!!

I'll say Scorpion's ninja sword because it goes on fire while whooping asses.

My favorite weapon is the Kwan Do.

me too I think (over 20 days)

hook swords!! 2nd is kwan do!!

Nunchauks-One f the most fastest weapons in de game and very useful.
Blades-This weapon does serious demage if u noe how to use it.

i personally like the axe, nunchaku, gauntlets, naginata, kunlun dao, morning star and kali sticks, but my utmost favorite has to be ashrah's *winks at tomzers and giggles* kriss! that thing is fucking powerful! if used right ashrah *giggles again* is a beast!
stage weapon concerned... has to be the cleaver, it's hard to get it due to the fact it's right infront of the damn meat grinders, but the shit is extremely powerful, again in the hands of ashrah it's even more deadly.

I really enjoy fighting with the Nunchaku, Kori Blade, Katana, and Kali Sticks.

I also like the Sai.

Definately Kobu Jutsu. Were Jax's Tonfas always exactly like the Kobu Jutsu, or did they just do that for this game?

Yes Kobu Jutsu is an amazing weapon and its Tanyas saving grace because one of her fighting styles is quite weak.
I also like Scorpions, and Kenshis katana.

I like sai and nunchaku.

i forget to say katana

Hookswords by far. Kabal > You.
