Dragon Ball Z
Super Saiyan Goku used this attack in his battle against Freeza in his Full Power form on the nearly-destroyed Planet Namek. After being elbowed into a cliff by Super Saiyan Goku, Full Power Freeza attacked and knocked Super Saiyan Goku down to the ground before saying he was just a beast. However, Super Saiyan Goku stood up and replied he would rather be a brainless beast than a heartless monster like Freeza. An angry Full Power Freeza tried to attack Super Saiyan Goku again, but Super Saiyan Goku dodged the attack and countered with the Meteor Smash rush, smashing Full Power Freeza across the ground.
