By absorbing the powers of two fiery foes, you can transform into a fireball to charge and char anything in your path.”

Super Fireball is a Power Combo used in Kirby 64: The Crystal Shards made by mixing two Burning abilities. Super Fireball travels farther and does more damage than regular Burning, and the length of travel does not decrease with repeated usage.
Kirby transforms into a form somewhat like a phoenix and flies forward on fire. This attack is only different from normal burning in the way that it is larger, stronger, and travels farther.
