Movie 4:

The Movie starts off with Gohan and Ickoris going to visit piccolo so they can show him a dance while gohan whistles(Yes believe it or not, this does have a point). But, Piccolo, in pain, yells for Gohan to stop. There is a small planet Heading towards the earth and everyone is freaking out, so Goku goes with Krillin to try and deflect it with their Kamehamehas. Although they fail and it still crashes down.. An evil super namek named Slug is the one who owns the ship, he orders his crew to launch a satelite which completely freezes the earth. Slug sees Gohan with a Dragon Ball on his cap so he decides to round them up, he wishes to be young and this is granted, making him extremely powerful once again. Goku and Piccolo Take out Slugs men then try to take him down. Slug is more powerful then Goku though at the time. Goky then turns into a Super Saiyan for a while, and wrecks Slug like he's nothing. Slug then becomes a giant and starts beating on goku. Piccolo tears off his own ears, then yells for Gohan to whistle again; because nameks ears are extremely sensitive, so whistling hurts them.. Slag drops to his knees, and Piccolo gives his energy to Goku. He flies up above the clouds and forms a Spirit Bomb, which he then uses to kill slug. Yakirobe comes and gives out Senzu beans. Right before the movie ends, we see Master Roshi waking up then saying what a beautiful day it is!He slept through the whole thing!
