Age 781 is a major year in the Dragon Ball universe.
- According to Daizenshuu
- The 27th World Martial Arts Tournament takes place. Mr. Satan wins. Buu comes in second place.
- According to the Ages in the Xenoverse games
- The present day events of the Prison Planet Saga seemingly occur.
- The events of the Universal Conflict Saga seemingly occur.
- The events of the Universe Creation Saga seemingly occur.
Alternatively, since Shenron was summoned in the anime version of the Universe 6 Saga (making it occur a year after the Golden Frieza Saga), the anime's version of the Universe Survival Saga would have to occur this year due to Super Shenron's usage in the Universe Survival Saga; making it have to occur a year after the Universe 6 Saga. This would in turn move the above events in Dragon Ball Heroes to Age 782.
