To give your character his alternate costume, select him with Y instead of A.
This is my favorite charater of the entire game, and I know ALL of his moves and combos. I have also mastered every character (Especially Lee)except Iruka. Anyways, I know to get a Knock-Out with Lee within seconds! This all you have to do (You might want to practice this on Training to get it right): First, press <-- + B towards the opponent to block and hurt him/her at the same time, and to get him/her into a corner. Then, press <-- + B, B, A, A, A, and he/she should fly up (They wouldn't fly over to the other side of the arena because they are in a corner.) and come back down. When he/she is about to hit the ground, press B, B, B, B, B, B, A, A, A, A, and he/she should fly up again and come back down. When he/she is about to hit the ground, press X for Lee's special since you got up your Chakra Gauge from doing the combos. The opponent will hit the ground and bounce up into your special that starts with a kick upward. Right after you do the attack, run towards the opponent by pressing towards the opponent then pressing towards the opponent again (Just hold it this time!)and press A while they're getting up. He/she will fly across the arena. Run towards him/her and press --> + A right when they got back up. This SHOULD K.O. the opponent and leave you a Perfect Victory! Note: The opponent will sometimes use his/her Substitution Jutsu (See Handbook for details) to avoid your combos. If he/she does, just try again.
As Haku, jump up in the air and press A to fire needles. If you hold it, they will remain in the air, but it uses Chakra VERY fast. Let go to release them. Once you hold them, they will automatically point to your opponent. It will follw them wherever they go. NOTE: the needles can only go down, or in a 90 degree angle. They will not go pointing at you if your opponent is to close. Also, hitting L and R may dodge it. The chances of it not are like 3%.
For those that need help with Survival Mode, use Kyubbi Naruto because he's fast, strong and a true killer.
To get Kyubbi Naruto, beat one player with everyone including Rock Lee.
To get Rock Lee, beat story mode, then he will challenge you. If you beat him, you unlock him.
To unlock rock lee you must beat storie mode without a continue. Once you fight lee (be careful he's tough!) you will unlock him
Reccomendation:Set the game level to easy before doing this.
At the start of the battle, use the A button combo and it will take damage as much as special, then use his special, then use the A button combo to finish it off
You can play with Haku without his mask by pressing X or Z.
Kyuubi - To get Kyuubi Naruto, you need to beat Story Mode with Naruto first,when you get to Rock Lee,with no continuing,beat him and you will Unlock him.After that, go back to the Main Menu and choose One Player mode.Beat every single character including Rock Lee twice(I think) and after you beat the last one, you'll get a message saying you can use Kyuubi Naruto by pressing X or Z when choosing a character.
Sharingan Kakashi - Beat One Player mode with Kyuubi Naruto and then go back to One Player character select and beat One Player mode with Kakashi, at the end it will say to press X or Z while choosing a character to activate Sharingan Kakashi
During an opponents' special, hit A and back at the same time. Make sure that you hold it when your opponent hits you. The only downfall is that you can't copy Haku's special because it's a "secret jutsu".
