Future Trunks and his timeline suffered severe damage indirectly caused by the diminutive villain, Emperor Pilaf.
One of the most renowned characters in Dragon Ball Z is a warrior from a different timeline - Future Trunks. In the timeline where Future Trunks lived, Earth was nearly destroyed, and most of the Z warriors had perished. Why did this happen?
Dragon Ball Super unveiled the horrifying reason behind this catastrophe, revealing a seemingly insignificant antagonist, Pilaf, as the instigator.
In a concise flashback chapter, Dragon Ball Super revisits Future Trunks' timeline. At a crucial moment, when Trunks was still a child and the battle against Androids 17 and 18 continued, Goku succumbed to a heart virus and passed away. With the strongest warrior gone, the Z fighter group couldn't defeat the two Androids created by Dr. Gero. Subsequently, Gohan and Bulma desperately sought the Dragon Balls.

The story of what transpired in Future Trunks' timeline is disclosed at the end of chapter 2 of the manga Dragon Ball Super. Pilaf, along with his henchmen Mai and Shu, collected all the Dragon Balls to summon the dragon god Shenron. However, Pilaf ignored Shu's warning and wished to become young again. Unfortunately, Shenron misinterpreted their wish and turned them all into infants.
The problem here is the final wish that Shenron granted in this timeline. With Piccolo's demise shortly after, the Dragon Balls turned into ordinary stones. No one knows how to reach Namek to have Dende wish Piccolo and the Z fighters back to life.

Pilaf's actions not only destroyed Future Trunks' world but also sealed Earth's grim fate. By stealing crucial wishes from Bulma and Gohan, Pilaf paved the way for the Z fighters' downfall, leaving only Bulma and an aged Trunks in a dark future.
In summary, this short chapter has explained some inconsistencies, such as Mai's age in the future. Pilaf's audacious desires significantly reduced the chances of defeating the Androids, creating the darkest timeline in the story.
Ultimately, the presence of Emperor Pilaf, initially thought to be a minor annoyance, became a major issue. The story of Pilaf and his interference in Future Trunks' timeline is evidence of how even secondary characters can have significant impacts.
