What characters who died in Part 1 would be a powerful Ninja in Shuppiden

[Demon of the Hidden Mist]

Off the top of my head i cant really remember alot of ninja that died part 1. Some are Zabuza,Haku, Sound Four,Kimimmaru(bad spelling),3rd hokage
it should be commen sense that if any of these ninja were still around they would be much more powerful cuz ninja keep training to get stronger. What ninja that has died in part 1 would have been a great ninja. My pick would be Zabuza he was such a cool character. He would have beaten Kakashi if it wasnt for Naruto and Sasuke. I think if he didnt die he would be one of the powerful characters around today

Possibly, Zabuza would be cool.
I think that Dosu would be the best though.

Sound Ninja 4. (including Kimimaro)

[TOKIE_TOKIE]

kimimaru, haku, dosu, zaku

[Hidden Ninja45]

Haku would probably be a lot more powerful. The first Sound Ninja 4 would probabably be more powerful. The second Sound Ninja 4 and Kimimaro I think wouldn't of gotten any stronger.
