"It was poetic using Earth's dragon to save me from Earth's Hell. Oh, you can't imagine the depths of my suffering there. I spent most of my days strung up like a damn pupating moth, trapped over a field of delicate little flowers where bands of angels and fairies and enchanted stuffed animals lived! They played songs and danced asinine jigs as if their only care in life, was when they would get their next warm, fuzzy hug! Instead of ruling the universe with an iron fist, I was serenaded by teddy bears!"
Earth's Hell (地球の地獄 Chikyū no jigoku), is a district of Hell, close to Other World, where evil characters go if they died on Earth. Though it wasn't shown in the original Dragon Ball manga, it is seen in Dragon Ball Z: Resurrection ‘F’ and Dragon Ball Super.
Hell has drastically changed due to Akira Toriyama being more involved. The area in which Frieza is kept is a scenic, flowery field with trees throughout it, run by the Angels of Hell. Frieza is sealed in a cocoon, hanging from a tree above a field of flowers where stuffed animals parade while fairies and angels dance. Earth's Hell notably has more areas aside from this flower field, such as an underwater area where the flower field in which Frieza was kept is located, a rocky volcanic area above that section and a frozen tundra. Bats appear to be a common inhabitant of hell.
Dragon Ball Z
Hell appears in Dragon Ball Z: Resurrection ‘F’. Frieza is in Hell being tortured by the Angels of Hell while they played their music. Sorbet and Tagoma wished Frieza back to the living world, Frieza leaving his cocoon in Hell. As Frieza was revived and killed again, he was sent back to his personal Hell after his death by Goku, again being tortured by the Angels.
