Dragon Ball Z: Dead Zone

Piccolo (Dragon Ball) is attacked and supposedly killed by a group of shadowed fighters. Meanwhile, Chi-Chi (Dragon Ball) along with her father, Ox King, and Gohan (Dragon Ball) are attacked by the same group. Goku is out fishing during the attack and after sensing danger, he returns only to find his son has been kidnapped. The group responsible for the attack are Garlic Jr.'s henchmen, and it is later revealed that their reason for kidnapping Gohan was to retrieve the four-star Dragon Ball that was attached to his hat. After gathering the remaining Dragon Balls, Garlic Jr. summons Shenlong (Dragon Ball) and he immediately wishes for immortality. Shenron, never having had to grant this type of demand before, grants Garlic Jr. his wish. A furious Goku arrives to try to take back his son, but soon discovers Garlic Jr.'s new power. Kami (Dragon Ball) makes an appearance (which surprises Garlic Jr., who thought that his henchmen had killed Piccolo) and meets up with Goku, and describes a brief history of Garlic Jr. and his father Garlic. Goku then proceeds to try to find Gohan when he is attacked by the villain's gang, whilst Kami faces Garlic Jr.
