The Prison Planet[1] (監獄惑星 Kangoku Wakusei) is a set of seven planets chained together and used as a prison by Fu.


One of the planets resembles real world Earth, another resembles Saturn, one planet is mechanized (like the planets of Universe 3), while another appears to be made almost entirely out of lava. The planets are tied together by massive chains, with a keyhole being present at the center.

One of the planets that makes up the Prison Planet is Babari from Universe 10,[2] here referred to as Green Area. Future Trunks was initially imprisoned on the Slum Area[3] planet of the Prison Planet. King Cold's forces are locked in combat with Hatchiyack's ghosts on the Chaos Area planet.

The nucleus of the Prison Planet is the Core Area, where several powerful warriors were contained.[4] It is a volcanic planet.[5]

The planet contains its own new set of Dragon Balls, simply referred to as "Special Dragon Balls" by Fu, which are needed to leave the planet.


The Prison Planet was created by Fu in the second version of the future timeline where Future Trunks lives after the "Future" Trunks Saga[6] as an experimental site[7] and also as a prison, numerous warriors from across time and space were imprisoned here as part of Fu's experiment.

In the game and anime, following the end of the battle between Ultra Instinct Goku and Super Saiyan 3 Cunber, the planet exploded, in the manga the planet's were separated by Oolong's wish and returned to where they came from.
