Future Trunks
Future Trunks is the older version of Chibi Trunks. He is a time traveler. When he grew up, he watched all of the Z-Warriors die, even Goku, who died from Heart troubles. Future Trunks travels back in time to save Goku with pills that he brought to cure his heart troubles so Goku could battle later with androids 17 and 18. While in the past, he defeats Freeza but is later killed by Cell. He was brought back with the Dragon Balls and then returned back to the Future more powerful and easily defeated Andriods 17 & 18.
Confusing huh?
