it was the 4th that stopped the kyuubi. he was standing on top of gamanbunta and then he sealed it. you should use manga info rather than anime info since this is a manga discussion forum. it's been said on several occasions that the 4th sealed the kyuubi in naruto so we must take it as fact.
Simple answer Yondaime. YouTube - Naruto episode 1 part 1
Check clip. Those two people are regular Konoha nija's. Most significantly they both die when Kyuubi swings his tail wiping the both out along with trees. Next in the video are a group of chunin and Jounin who hold Kyuubi back till Yellow Flash arrives. When yondaime fights the Kyuubi, you can clearly see him alone on Gamabunta. End of.
YONDAIME. every character in the manga said so, why doubt them?
the other people you mention, where ninjas trying to slow him dowm untill
the 4th came to help them, even in the anime they say that.
unless this was a joke thread this deserves to go to some kind of hall of fame for its stupidity
Your mom my guess ! Shes uber ninja XD
What chakra type are you?
A pie in the sky?
