How Well Do You Remember "Dragon Ball Z"?

Unlike the members of Frieza's army, the Z Fighters had the ability to hide their true power level and could almost mask it completely in difficult situations. This ability made it difficult for Frieza's army to find them when they arrived on Namek, even with their scouters.

With Frieza defeated, one of Vegeta's primary goals in life had ended. Rather than return to conquering planets, the Saiyan prince decided to make a life on earth and started a family with Bulma.

In the backstory to how Frieza came to rule over the Saiyans, it was revealed that he destroyed their home planet because he feared the legend of the Super Saiyan. Vegeta always believed it would be he who reached the legendary form, but it turned out to be Goku.

During the Saiyan Arc, Goku learned that he's actually a member of the Saiyan race sent to earth to destroy all life. However, Goku fell down a ravine as a child and hit his head, changing his personality for the better.

Bulma invented the Dragon Radar to make locating the Dragon Balls much easier. The radar showed up in the first episode of "Dragon Ball," when Bulma first ran into Goku and their journey together began.

The five members of the Ginyu Force were lethal warriors who could hold their own against anyone in the galaxy. Though they were recognized for their fighting skills, they were also known for their unique poses, which they would strike before and during a battle.

In the Hyperbolic Time Chamber, time played out completely different as one day on earth equaled an entire year in the chamber. This time difference made it the perfect place for the Z Fighters to train as the Androids sought them out on earth.

The Lookout often serves as a place for the Z Fighters to retreat and train for some evil force attacking earth. Goku trained there before the 23rd World Martial Arts Tournament, and Krillin, Yamcha, Tien, Chiaotzu and Yajirobe went there to prepare for the fight against the Saiyans.

Captain Ginyu's body switch technique got him out of a lot of trouble, like when he stole Goku's body after his own was battered in battle. However, the technique also worked against him, as it did when Goku threw a frog between Ginyu and Vegeta while he was using the move, forcing Ginyu into the frog's body.

Imperfect Cell used a time-traveling ship similar to the one used by Trunks to travel back to the past, where he could find the Androids that would help him reach his perfect form. However, Cell first had to increase his power by absorbing the biomass of humans before confronting the Androids.

The Spirit Bomb is a technique that can only be used by someone with a pure heart. Otherwise, the attack kills the user. The strength of the Spirit Bomb depends entirely on the organisms that are willing to provide it with energy.

Prior to the events of "Dragon Ball Z," Piccolo was one of the main antagonists in the "Dragon Ball" series. Seeking revenge for his father, Piccolo fought Goku in the 23rd World Martial Arts Tournament, but Goku came out victorious.

The daughter of one of the Earth's top scientists, Bulma is extremely smart and a willing explorer, proven by her quest for the Dragon Balls in the "Dragon Ball" series. However, she also carries around DynoCaps, which provide her with all the luxuries she'd find at home.

The Demon Realm was created by evil wizards at the tip of the universe. Dabura was the king of the realm before Babidi placed a spell on him, turning Dabura into his minion as he tried to resurrect Majin Buu.

Together, Goten and Trunks used the Fusion Dance to form the warrior Gotenks. Though he was cocky and mischievous, Gotenks was also extremely powerful and was only the second Saiyan to transform into a Super Saiyan 3.

Dende was one of the main reasons Vegeta was able to raise his power level significantly as he prepared to fight Frieza because the power of a Saiyan, like Vegeta, increased anytime they were healed from a near-death experience. Once Frieza realized this, he killed Dende.

To defeat the Androids, Piccolo had to cast aside his pride and fuse with the very person who cast him aside years ago in an effort to purge all evil from his body. Both warriors were reluctant to join back together, but Kami sensed an even bigger threat than the Androids on the rise.

When Goku faced off against Vegeta, he had to power up his Kaio-ken by three to gain the upper hand in the battle. Then, after Vegeta decided to destroy the earth, Goku took the Kaio-ken up another stage, which saved the planet but left his body battered.

Aside from his desire to kill Goku, Android 16 wasn't all that bad a guy. He had a love for all other life and tried to protect it when he could, but his programming wouldn't allow him to ignore his pursuit of Earth's greatest hero.

Gohan always had a hidden power, which was only released in spurts when he got angry enough that he had no other choice. When he finally reached Super Saiyan 2, however, he maintained the form long enough to get a victory over Cell.

Though the Z Sword was supposed to be one of the strongest weapons in the universe, it broke after Goku threw a giant cube made of the densest material known at Gohan to test the sword's limits. Surprisingly, the sword breaking was actually what released its power, which turned out to be the deity, Old Kai.

Zarbon was obsessed with his appearance, so he didn't like to transform unless he was in a dire situation. Vegeta brought out this transformation in their first fight on Namek, though the monstrous Zarbon quickly overpowered Vegeta during this encounter.

Every Saiyan has the ability to transform into a Great Ape if there's a full moon around, including Gohan who is only half Saiyan. Piccolo realized that the Saiyan invaders could use this to their advantage if he didn't destroy the moon first.

To test the power of the earthlings, Nappa planted six Saibamen, which all had a power level of 1,200. The Z Fighters proved to be too much for the Saibamen, but one of them did latch onto Yamcha and exploded, taking Yamcha down with it.

Upset that Goku didn't find his jokes funny, King Kai demanded that Goku make him laugh if he wanted to receive training. Goku finally answered the demand when he asked, "Why did the chicken cross the road?"

Aside from warning the Z Fighters about the Androids, Trunks also returned from the future to give Goku medicine for when the heart virus finally hit him. His hope was that Goku could change the course of history and that events wouldn't turn out as bleak as they were in his own time.

Having finally become a Super Saiyan, Vegeta believed he was the strongest warrior in the universe. His arrogance got the best of him when he faced off against Android 18, who easily defeated him and broke his arm in the process.

Though he was considered one of Earth's strongest warriors, Yajirobe was never the bravest fighter on the planet, often choosing to run from a battle rather than go down fighting. He stayed around long enough against the Saiyans, however, to land one of the most critical blows of the fight when he cut off Vegeta's tail.

For a human, Krillin has many unique qualities when it comes to his appearance. Aside from the six dots on his forehead, referencing a practice carried out by Shaolin monks, Krillin also doesn't have a nose, which has become a running joke with fans.

In Other World, King Yemma, king of the Ogres, stood judge over the souls of the fallen, determining which souls would enter heaven or hell. Yemma informed Goku that if he took Snake Way to the end, he would be able to train with King Kai.

While on Yardrat, Goku learned one of his most famous techniques: Instant Transmission. At first, the move just helped Goku move quickly from place to place, but he eventually incorporated it into his fighting style and used it in conjunction with his Kamehameha.

Before he settled on earth, Vegeta relied on his ruthlessness and hatred to fuel his power. Believing that Goku only surpassed him because he had grown weak, Vegeta turned back to his old ways by allowing Babidi to cast a spell over him, which only gave Babidi temporary control of the Saiyan prince.

The idea of using gravity to train on the spaceflight to Namek wasn't the first time Goku utilized this training technique. When he trained with King Kai, the planet they were on had a gravity 10 times that of Earth. He just decided to up the ante on his way to fight Frieza's forces.

While training with Vegeta, Trunks thought he had surpassed his father in terms of power, and in many ways, he did. However, that power came at a great cost to his speed, which Cell demonstrated to him during their fight.
