Choose SS Goku, Majin Vegita, and Bardock as a team for the best results. Use Goku first. Keep blasting him. Every time your energy level starts to go down too far, use Bardock and keep blasting. Eventually he will get around. However by the time he does that you will already have him down far. When your life gets into the red, use Goku's ultimate attack. If Goku dies, try the same technique with Majin Vegita. If you do not get it, try again.

Well, this is the team that i always use, and it's easy to beat the MAximum mode with it. You need Majin Buu, Dabura, and another warrior of your choice (Preferrably Broly, he has more health than any other DBZ character in the game), and use Dabura's spear throw to keep the enemy at bay, while charging your power with Buu, then unleash your team attack on the enemy, keep repeating as so. If you run out of support uses or Buu gets low on health, switch to Broly to conserve Buu until you get enough power to change back to Buu and attack again.

This will tell you how to use the Triple Fury Family Kamehameha to it's best use.
To use this, pick your team to be Gohan (SS2), Goku (Normal) and Bardock. Use Bardock to get your power up to 200%, then unleash the team attack. Normally, with just Goku and Gohan, the attack would hit the enemy full on. This time, the enemy blocks the attack, but Bardock appears at the top of the screen! He unleashes a Ki Cannon attack, and your opponent takes a huge amount of damage! A lot of characters are usually killed outright by the attack, it is so powerful.

Happy battling!

Okay here is what you do. Select ssj Goku, Gohan(Teen) and ssj3 Gotenks. When you are in a fight get your power to 200 and press the team attack button. The attack will start off with Goku and Gohan blasting the tartget then Goten will appear at the top and add his own blast the resulting attacxk will do 153 or 160 rush which whill K.O your enemy.
