The Dead Zone is a hyperspace void of darkness created by Garlic that sucks people in and leaves them floating through pitch blackness forever. Garlic's son Garlic Jr. opened the Dead Zone twice by heightening his ki to open a portal to it, but both times he was sucked into it and the void closed up. When sealed the first time, the seal shattered into various pieces, which all have Garlic Jr. knocking futilely to escape. Although a void of darkness, it is not immune to the effects of time from the main dimension even when closed, which is especially evident by how Garlic Jr. ultimately escaped the first time due to feeling the energy of the Makyo Star's passing by Earth.
In the movie, Dragon Ball Z: Dead Zone, he opened it in an attempt to suck in Goku, Piccolo, Kami, Krillin and Gohan. Gohan was able to resist its suction and knock Garlic Jr. into the Dead Zone. He swore to come back and reminded them that he was immortal, and at the end of the movie, one can see a withered Garlic Jr. trapped within the glass-like fragments of the Zone.
Garlic Jr. remained in the void for about three years until the Makyo Star got close enough to Earth, allowing him to escape from it. In the Garlic Jr. Saga, Garlic Jr. reopened the Dead Zone in retaliation to his dark plans being foiled (Kami and Mr. Popo had broken his curse on the people of Earth using the Sacred Water). Piccolo, Krillin, Kami, and Mr. Popo were nearly sucked into the Dead Zone, but Gohan destroyed the Makyo Star, draining Garlic Jr.'s fearsome strength and causing him to be sucked into the Dead Zone once again.
Being immortal, Garlic Jr. is still trapped inside the Dead Zone by the end of Dragon Ball Z and will be for the rest of eternity.
