First, you need to unlock Piccolo, and unlock his 3rd and 4th tray slots. Then, Equip Piccolo with Special Beam Cannon lvl. 3, Destructive Wave and Light Grenade lvl. 3, Roast Pig(or something like that, it may be Roast Beef, etc.), Transform lvl. 2 (which should allow you to fuse with Nail and fuse with Kami), Hidden Ki lvl. 5(or 4, whichever is max), Ki Control! Lvl. 5(or 4, whichever is max), and Figher's Body lvl. 5, which is max. That will allow Piccolo to start a battle with full health, and when you get weak, Hold the X button and press down on the control pad or left analog stick twice to recover 5 bars of health. The other abilities allow you to stay in Ki Burn mode longer and allows you to consume less Ki while using your Ultimate attack. Since Special Beam Cannon does not allow a power struggle for the opponent to receive less damage, and being as fast as it is, it is literally impossible to dodge at close range, and very difficult to dodge at medium range. With Hidden Ki maxed, using Special Beam Cannon only consumes about 2 Ki bars instead of about 4 or 5. And when you are in Ki Burn mode, your ki doesn't decrease when using a ki-based attack, but instead over time. So when you have Ki Control! Max equipped, it allows you to stay in Ki Burn Mode for a good deal longer. So, before the battle starts, fly away from your opponent, charge your ki to a high level, then let your opponent get in close. When he/she is about to attack, use Transform! To stun them, then quickly enter max power mode, then use Special Beam Cannon. Then, Right when he gets up, he will roll to the side simultaneously. Right when the side step/roll is almost done, activate special beam cannon again. If both hit, then the opponent's fatigue bar will have been built up, and he will be temporarily stunned. Wait for him/her to COMPLETELY stand up, then use Special Beam Cannon a third time. Then, once he/she will get up, they will most likely Dragon Dash to the side. When the Side dash is almost over, then use special beam cannon a fourth time, and they should be dead. If you charged your ki high enough at the beginning of the battle, you could do this all in one Ki Burn Mode. I killed Kid Buu this way. Hope this Helps!!
