I like the Boomerang Idea that rocks.
It'd be cool if you could use the whip like the Guys in Welcome to the jungle.

I think Kira or Tanya should have the weapons you say. Tanya's boomerang was cool, and a whip for another lady fighter would be a good idea. The ladies always get sexy weapons...the fans, sai's, I hope they keep them with the more skillful and interesting weapons, rather than the huge swords and such that the men seem to get.
Long live the ladies!!!!

Well I have already said before I'd like Kira to get a ball and chain, like Go Go Yubari on Kill Bill!

Tanya's Boomerang should be retained. It should be similar to a Predator's throwing disc, ie. sharp and high tech. One fatality should involve it taking out an arm on the way through then lopping off the head on the way back. Tanya should then hold it in the air and we should all see blood dripping from it.

The boomrang ideas here are cool. I think it would be logical to think that Tanya will continue the use of the boomerang as her weapon of choice....however I think that chances of us seeing a whip are very, very slim. Also The Kwan might not be the final weapon for Sindel, that could change like the fighting styles at anytime. I think that it should, or if it doesn't take the Naginata away from Hotaru, because IMO the weapons are too similar. Then again they seem to be used quite differently by Sindel and Hotaru, so scratch what I said about taking one or the other out...but that still doesn't mean that Sindel will end up with the Kwan as her final weapon. Hotaru's weapon fits him, Sindels current weapon seems out of place in her hands...so we'll see.
