This what if follows the events of the Facing the Emperor chapter, which follows the 23rd World Tournament chapter. Start there first.

Frieza, at long last, had been defeated. The one that existed as a reminder for the Saiyans that they can never truly rest and a reminder of their time as slaves... Is no more. Thanks to the power of the legend, Celeron the Super Saiyan!

Once the Dragon Balls have been used and Piccolo brought back, Kami returned to life as well, which rendered the Dragon Balls of Earth useable. However... Someone had already been waiting for it. Someone lurking in the shadows... The remnants of the Red Ribbon Army: Doctor Gero.

After he had collected them, he had used the Dragon Balls to find warriors powerful enough to eliminate Son Celeron and Son Goku for destroying the Red Ribbon Army. Said warriors were already on their way to Earth, while our heroes had been getting off of Namek.

At the very same time as our heroes return to Earth... A new child had appeared. One with the power to transform into a Super Saiyan, a warrior from the future: Layla. What message does the future have for our heroes?
