I just have to say, the summoning he did on Zabuza was different to the summoning he's done otherwise. The reason for the scroll was so that the dogs knew what scent to follow (he wiped his blood - for the contract AND scent - on the scroll) - THEN the had to make sure they were summoned into the ground to burst out where Zabuza was (this is why he didn't just summon them where he was standing and let them sniff him - Zabuza would have known they were comming - hence the need for the scroll).Originally posted by: Edort4
Kakashi was inside mist very worried about sasuke and naruto fighting a very strong opponent, and at that time of the history fights were less ficticious, to make a crappy summoning of 6 dogs he needed 2 minutes a scroll, his blood on the opponent and a lot of hand seals. Now he summons in a blink of an eye.
Otherwise, he's only needed blood for the contract which he's put on his hand and the seals which (as we have seen are pulled off VERY fast - they are only slowed down so we know what they are doing.)
And now for something on Topic - If Haku is so much stronger than Kakashi... why did he suicide by jumping in the way of Kakashi's attack? why didn't he just use his superior strength and ability to stop him? Plus we have to consider that at that time, Kakashi wasn't even at his top form - he mentions during his cliff training that he's let himself go - whereas Haku was going all out.
Oh, and something esle - Naruto is a great ninja, not the best, but he's not the blithering idiot people make him out to be. He's masterd 1 Jounin level skill, and reinvented 1 Sannin level skill, and neither require the Kyuubi to use. Without the Kyuubi, he'd STILL be pretty good, even with low-grade Chakra control.
