While fighting 100% Final Form Frieza in the storyline, if you can get close enough without him attacking you, repeatedly press Y + LT. You can keep hitting him without him being able to attack back. If he does get out, you can also repeatedly use a Kamehameha.
Use the Left Analog-stick and Right Analog-stick to roll the Dragonballs along the ground. Press X and Y to make the Dragonballs bounce very high. Repeated pressing can result in extreme height on Dragonball bounces with the correct timing. Press A and B to get a weaker bounce.
