1. Tien
   Yamcha
2. Chiaotzu
   Krillin

A member of the Three-Eyed clan, Tien was trained by Master Shen of the Crane School. Using the skills he learned, Tien entered the 22nd World Martial Arts Tournament, where he faced off against Goku in the Finals. Tien won the match due to luck when a truck hit Goku as both fighters fell to the ground.

1. Ki sensing ability
   Scouters
2. Wristwatch
   Ki radar

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.

1. Yamcha
   Goku
2. Vegeta
   Tien

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.

1. Extended Saiyan
   Saiyan God
2. Super Saiyan
   Saiyan Blue

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.

1. Frieza Arc
   Buu Arc
2. Saiyan Arc
   Cell Arc

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.

1. Frieza Force
   Ginyu Force
2. Kai Force
   Elite Force

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.

1. Kame House
   The moon
2. Namek
   Hyperbolic Time Chamber

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.

1. Hyperbolic Time Chamber
   The Lookout
2. Fire Mountain
   West City

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.

1. Teleportation
   Self destruct
2. Revival
   Body switch

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.

1. The Dragon Balls
   Absorbing humans
2. Training
   Solar power

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.

1. Spirit Bomb
   Kamehameha
2. Tri-Beam
   Special Beam Cannon

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.

1. Goku
   Gohan
2. Tien
   Piccolo

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.

1. Chi-Chi
   Videl
2. Bulma
   Kami

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.

1. Earth
   Sacred World of the Kai
2. Demon Realm
   Namek

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.

1. Gohan
   Krillin
2. Goten
   Vegeta

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.

1. Teleport
   Summon the dead
2. Turn invisible
   Heal others

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.

1. Dende
   Chiaotzu
2. Kami
   Nail

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.

1. Kamehameha
   Kaio-ken
2. Spirit Bomb
   Instant Transmission

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.

1. Android 16
   Android 17
2. Android 19
   Android 20

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.

1. Goku
   Vegeta
2. Trunks
   Gohan

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.

1. Spirit Sword
   Z Sword
2. Energy Blade
   Sword of Hope

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.

1. Heavy
   Unnecessary
2. Ugly
   Too powerful

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.

1. It caused Gohan to transform.
   It was too bright.
2. It made him weaker.
   He wanted Gohan to know darkness.

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.

1. Pods
   Saiyan DNA
2. Vegeta's ki
   Seeds

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.

1. Fight him
   Bring him food
2. Shine his shoes
   Make him laugh

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?"

1. He gets a heart virus.
   He is outmatched in battle.
2. He is wished away.
   His power is stolen.

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.

1. Leg
   Arm
2. Ribs
   Back

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.

1. Destructo Disc
   A ki blast
2. A sword
   Scissors

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.

1. Three
   Six
2. Eight
   10

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.

1. Spirit World
   Other World
2. Heaven
   Namek

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.

1. Luud
   Popol
2. Slug
   Yardrat

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.

1. To release the darkness in his heart
   To gain access to Majin Buu
2. To defend the earth
   To defeat Majin Buu

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.

1. 100x
   300x
2. 500x
   1000x

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.

1. His power
   His speed
2. His ki
   His technique

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.
