Perfect Cell, Cell Juniors, and Mr. Satan are empowered by Towa's Dark Magic becoming Dark Perfect Cell, Dark Cell Juniors, and Dark Mr. Satan. The Z-Fighters & Gohan are overwhelmed and Dark Perfect Cell and two Dark Cell Juniors use their own version of the Father-Son Kamehameha to kill Gohan.
The Future Warrior arrives in Age 767 and saves Mr. Satan from being killed by Dark Cell by humorously kicking him out of the ring. The Future Warrior is tasked by Future Trunks in the Time Nest to defend Mr. Satan and they manage to do so until Mr. Satan attacks Cell and is backhanded by him into a nearby mountain. Mr. Satan survives and that part of the timeline is restored.
Towa uses her Dark Magic to take control of Mr. Satan turning him into Dark Mr. Satan, granting him the ability to fly and use Ki Blasts who then attacks the Future Warrior for getting in his way. Meanwhile, Goku steps up to face Dark Cell.
The Future Warrior defeats Dark Mr. Satan, only for him to be revived by Towa's Dark Magic transferring Mira's energy into Mr. Satan. Meanwhile, Cell destroys the ring and removes the out of bounds rule from the Cell Games.
Dark Mr. Satan is finally defeated and returned to normal by the Future Warrior, while Goku forfeits and announces Gohan as the one who will defeat Cell. Gohan steps up to fight Dark Cell.
Trying to anger Gohan, Dark Cell unleashes the Dark Cell Juniors on the Future Warrior and the Z-Fighters.
Towa uses her Dark Magic on Gohan, allowing him transform into Super Saiyan 2 without Android 16's words of encouragement and death. However the Dark Magic prevents Gohan from killing Dark Cell. Meanwhile, the Future Warrior learns that Future Trunks has discovered Mira and Towa's location and defeats the rest of the Cell Juniors.
The Future Warrior confronts Mira and Towa. The Warrior is later joined by Future Trunks who transforms into a Super Saiyan to help him fight Mira. Mira takes on both the Warrior and Future Trunks, while Towa goes off to fulfil some sort of plan of hers.
After a hard fought battle, the Warrior and SSJ Trunks defeat Mira, however Mira gets back up revealing he was holding back. Towa returns and reveals that her plan to remove the Dark Magic controlling Gohan, taking away his Dark Super Saiyan 2 form had succeeded. This occurs shortly after Cell's return from his self-destruction and Goku's sacrifice, which results Gohan being weaken and left to face Dark Super Perfect Cell in his Full-Power Super Saiyan form. With their work done, Towa and Mira leave Age 767.
The Future Warrior returns to the Cell Games and assists SSJ Gohan against Dark Super Perfect Cell in order to restore the timeline.
