alternate story without vegeta
without vegeta, no one would have heard of db and frieza wouldnt be immortal. and then piccolo would have ruled the earth because goku wouldnt have trained further and piccolo wanted to conquer earth, gohan would still be a wimp with a pl of 1 - 500000, krillin would still be a bald spanish pimp, there would be no trunks, hmm goten, could be, could not be, boo wouldnt be because they wouldnt have enough energy to free him, but cell would be perfect, and goku would say as he sees him " what the heck! " because cell would be 1000x times no 50000x times faster and powerful.
cell would squeeze him with his mind. just with one look. but cell would have to stay on earth. he doesnt have the ability to live in space from frieza. but frieza would see him because of their monster big plasma screen scouter, and frieza just makes a deathball and destroys earth with cell before he kills him. but cell feels the deathball and send it back with a kamehameha. and then frieza dies on his planet. cell renames earth to wasteland because that name fits better now. on earth there is only one guy left. cell. and because there is no one left, he is tired. but because he has piccolos ability to make a doulbe of him he will train to be the strongest, that he already is. by the he killed babidi and the other guy so no boo. but cell is so dumb that he frees boo . but boo thinks "boo likes green guy" "boo helps green guy to go to other worlds" and they travel to everywhere. sometime they come to a planet called namek and cell says that he protects them if they give him the dragonballs. and since then he is immortal (now he can survive in space), much faster than light, and the last wish was for repopulating earth because he is bored.
