Freeza series
Yes, Dragonball Z returns in another season after the fight against Vegeta. This series helped improve Dragonball Z a lot because it is here that we are introduced to the Saiyans' ability to turn "Super Saiyan." (This series is twice as long as the Vegeta Series!) Freeza, who destroyed the Saiya planet in the battle with Bardock (Gokou's father) is in search of the Dragonballs to become immortal. The Z Warriors discover about Freeza's plot to conquer the universe and travel to space to stop Freeza and his minions. Vegeta joins the surviving Z Warriors, but only to insure that Gokou survives the battle so that he could kill him personally. (However, Vegeta ends up marrying Bulma, and Bulma is now pregnant with Trunks.) Everyone was killed in the battle against Vegeta except for Gokou, Gohan, Klilyn, and Yajirobe. Piccolo died protecting Gohan, so the Dragonballs of Earth vanished. Without the Dragonballs, Kami dies as well. Bulma later discovers that there are Dragonballs in the planet Namek (Piccolo's home planet), but it would take thousands of years to travel there. Then, Tao Pai-Pai appears and tells about the ship that Piccolo and Kami took to travel to Earth. With a faster spaceship, our heroes reach Namek and encounter Freeza. Next, and throughout the rest of this series, the Z Warriors fight against Freeza. Freeza had called on Team Ginew to fight the Z warriors, but Team Ginew was killed by Vegeta (except for Ginew, who accidently turned into a frog when he tried to swap bodies with Vegeta and Gokou threw a frog in his path). These battles go on episode after episode... On one battle, Gokou gets angry enough (when Klilyn gets killed) and reaches Super Saiyan level for the first time. (This is when the golden hair comes in.) He finishes Freeza off (as well as destroy Freeza's planet) with a single blast, and Freeza learns about the true powers behind a Super Saiyan. Afterwards, Gokou escapes to planet Yardrat, where he learns the ability to teleport. Freeza's father, Cold, later learns about Freeza's defeat and quickly gathers Freeza's body parts, which are floating around in space. His henchmen re-ensemble Freeza. (This is why Freeza was half robotic.) Freeza tells his father about Gokou and his powers, but his father believes that he is the universe's strongest warrior and doesn't believe him. (These villians are space conquerers.) Freeza, his father, and his crew land on earth to seek revenge on the Z Warriors, as well as destroy Earth on the way. But all of a sudden, a figure comes out of nowhere and adult Trunks appears. He turns into his Super Saiyan level and aids the Z Warriors in their fight. Trunks faces Freeza and his crew and easily kills them. (The dead Z Warriors were restored to life with a wish from the Dragonballs on planet Namek.) Trunks introduces himself as Bulma's and Vegeta's future son who grew up and traveled back in time with medicine to prevent the death of Gokou so that future would not be in chaos. Everyone thinks that Gokou is dead, but Trunks tells that Gokou is on Yardrat and will return soon. (This is the story of what happens in the next Dragonball Z series--the Cell series.) However, Vegeta is jealous over the fact that there is another Saiyan around -his own son- now, who is stronger than him. Character Notes: Gokou: Looks the same as he did in the Vegeta Series. However, he is able to turn into his Super Saiyan form 1 in this series! Gohan: is the same height as Klilyn now and has a mushroom haircut. (not strong enough to reach Super-Saiyan mode yet) Klilyn: Looks the same as in the Vegeta Series. Piccolo: Is officially one of the good guys now. (still no change in appearance) Vegeta: Begins to turn good, but doesn't admit it. He uses the excuse that he is only aiding Gokou so that Gokou will live long enough for him to kill Gokou personally. (does not turn Super Saiyan yet) Trunks: Vegeta's son. Because his father has black hair and his mother (Bulma) has blue hair, Trunks' genes gave him purple hair. Trunks comes from the future to save Gokou so that his future would change (but it still didn't). Trunks is a cool looking character with a split haircut. He can also turn Super-Saiyan. Freeza: galaxy conquerer. He killed King Vegeta (Vegeta's father, also the king of the Saiyans) and took over Planet Vegeta, where he used the Saiyans as mercenaries. Then, he killed Bardock (Gokou's father) and destroyed Planet Vegeta. Freeza can change into a few forms before reaching perfect form, but he finally is killed by Trunks.
