Dragon Ball Z: Lord Slug

Gohan (Masako Nozawa) visits Piccolo (Toshio Furukawa), who is annoyed by a whistling tune Gohan has learned to play due to his advanced Namekian hearing. An alien army led by Lord Slug (Kenji Utsumi) descends upon Earth, planning to convert the planet into a biological spaceship using magical Dragon Balls. As Goku (Masako Nozawa) and Krillin rush to intercept the meteor threatening the planet, Gohan defends civilians against the alien soldiers, eventually teaming up with Piccolo to stop Slug's army and defeat the powerful Super Namekian in an epic battle.
