After Dragon Ball Superwas launched, the series became the new official sequel to Dragon Ball Z, thereby removing Dragon Ball GT from continuity, which fixed a major plot hole created by GT.
Dragon Ball Super: Resurrection ‘F’ was originally an anime film about Frieza coming back to life after being killed by Future Trunks in Dragon Ball Z. After the film’s release, the events of the anime made it into the Dragon Ball Super manga by being referenced in Dragon Ball Super Chapter 32 by Akira Toriyama and Toyotarou as well as by receiving its own manga adaptation. In the storyline, Frieza is wished back to life after some of his underlings collected all seven of Earth’s Dragon Balls, then he commands his army to launch a full strike against Planet Earth. During the invasion, the Z Fighters face off against Frieza’s forces, and one of the tyrant's loyal subjects who was believed to be dead made an unscheduled appearance.

Back in Dragon Ball Z’s “Frieza Saga,” Captain Ginyu, the leader of the Ginyu Force, inadvertently used his body-swapping powers to inhabit a Namekian frog. Frog Ginyu was then transported to Earth along with all other Namekian creatures after Frieza’s battle with Goku was on the verge of destroying the entire planet. From that point on, Ginyu existed on Earth, alive and well, just in the body of a frog. In Dragon Ball Super, Ginyu is able to switch bodies with a member of Frieza’s army and regain the humanity he lost all those years ago, and in doing so, fixes a major Dragon Ball GT plot hole.
In Dragon Ball GT’s “Super 17 Saga,” a portal to hell opens up above the Earth and a number of past villains come flooding out, including Captain Ginyu.
