- Death Ball: Small ball of Ki used in a technique to destroy a planet via a chain reaction.

- Ki Blade/Cut: Capable of slashing thousands of meters of area with his finger (at 50% power).

- Telekinesis: Capable of moving rocks to throw at a target at high speed, or paralyzing weaker targets with Ki techniques and making them explode.

- Tsuibi Kienzan: Uses his Ki to generate up to two remotely tracking and homing energy discs; are much more effective when he uses his hands to increase their speed and cutting ability

- Punishing Blaster: Frieza gathers energy in his right hand, raises his hand, thrusts his hand forward and fires a massive blast causing massive damage. This attack is strong enough to destroy a large island and was used to kill Nail.
