Are you guys serious?? lmao Zabuza was defeated by a part 1 Kakashi with no MS. Speed will always outclass a slower opponent, and Zabuza has no strength feats whatsoever. You people are a joke.
Minato can summon Gamabunta with no hands like he summon Minato. And then Gamabunta finishes the job for him. Or Minato enters in his instant SM to win with a combo kicks tht will finish Zabuza.
