A vengeance from hell

Almost a year after the terrible battle against the demon Buu, the land finally returned to peace, but due to the consequences and the powers that Buu used, causing damage to Goku's dimension that was of great proportions frees the most menacing enemies from hell, of both the sagas and the films (specials), that is. Frieza, Coola, Cell, all of Doctor Maki Gero's androids, Tales and more; this also includes old enemies that the Sailors thought were defeated and to make matters worse, two enemies from Trunks' future join this imminent threat, and we'll have the worst of them all; the first monster that almost defeated the Z warriors, the second was Kid Buu, (however that is before the Cell games) and the Sailors are in grave danger like no other they've had in their life.
