This is not a fight where Plot no jutsu will helpGaara would win cause Gaara is one of the main characters
Hell no, not at once, is not like kakuzu will be standing there waiting to get hit.gaara his giant sand wave would crush all his hearts at once
I say Kakuzu wins, because they are both long range fighters, but he has more options and flexibility with his attacks. Gaara just has sand.Kakuzu might be a very bad matchup for gaara because:
gaara's sand coffin might not even affect kakuzu because of kakuzu's doton hardening abilities.
Kakuzu has both lightning and water monsters who could potentially be super-effective against gaara's sand.
That being said, I think the kazekage takes this, but only after a really hard battle.
I understand him having five hearts but being an Akatsuki Member doesn't really mean anything when your battling.kakuzu would win because he has 5 hearts, and because he's in akatsuki!
Base naruto about 200 chapters ago defeated 3/5 of kakuzu and that was when his rasenshuriken was only 50% complete, base naruto could probably completely defeat kakuzu now without summons. It would be kind of embarrassing if gaara couldn't beat kakuzu.I say Kakuzu wins, because they are both long range fighters, but he has more options and flexibility with his attacks. Gaara just has sand.
Kakuzu had also a century worth of battle experience, while Gaara comparatively is still fairly new to battling.
Its also basically a 5 vs. 1 fight. Gaara doesn't have the ability to win, I think.
