By the time Future Trunks goes back to the future, he is strong enough in Super Saiyan form to destroy Future 18, Future 17, and Imperfect Future Cell.
In
Shin Budokai - Another Road, Future Trunks is able to defeat Future Dabura, and later states that he could destroy Good Buu, showing that he had become far more powerful than during the Cell Games. During the game Trunks was capable of defeating not only Future Dabura but perfect puppets of Final form Frieza and Perfect Cell in his Base form.
Future Trunks is an important character in the story of
Xenoverse, he works for the
Supreme Kai of Time as her assistant and the head of the Time Patrol, he and the Time Patrol are based in
Toki Toki City (in Age 850) which houses the
Time Storage Vault. Because of the events that happened during the Android Saga, Trunks had wished to atone for his sins, thus joining the Time Patrol. Due to the main timeline's history being distorted, Trunks wished for a strong warrior to help him in fixing the timeline.
In
Dragon Ball: Xenoverse, Future Trunk's power is shown to have drastically improved over his last appearance. Upon meeting the Future Warrior for the first time Trunks takes all of his attacks and shows no signs of damage or fatigue. Later with the Future Warrior assisting him, Super Saiyan Trunks was able to fight on par with Mira (suppressed), a being whom was confident enough to believe he could beat Super Saiyan 3 Goku and Majin Buu at the same time easily even while suppressing his power. Later while working with the Future Warrior they were able to beat Beerus and Whis while they were testing their power, a feat that not even Goku could do. Shortly after while he was possessed by Demigra not only was he able to fight nearly on par with the Future Warrior but he was also able to resist Demigra's control and eventually broke free of his own will, a feat no one else was shown to be able to do.
