Android 8

This is the first android that we get to see in the series, when ordered to kill Goku he teamed up with him instead. He stars in Dragon Ball but we get to see him again at the end of Dragon Ball Z when people are donating energy towards Goku's Genki Dama.

Android 13

Android is the main enemy in movie 7. He stars with androids 14 and 15.

Android 16

The sole purpose of this android was to kill Goku. Android 16 was never meant to be activated and in Future Trunks timeline he was never seen. He does not seem to like fighting and enjoys nature. Later he fights against Cell and when he dies it triggers Gohan into turning SSJ2. Unlike 17 and 18 he is a full robot .

Android 17

Unlike Android 16, Android 17 was based on a human. After he is activated he destroys his Creator (Dr. Gero Aka. Android 20). He is too powerful for the Z warriors at first and he enjoys having a good time.

Android 18

Android 17's twin sister, she marries Krillin later in the series. Krillin used the Dragon Balls later to remove the bomb that is inside Android 18 which surprised her.

Android 19

Android 20's bodyguard, this android is extremely weak and requires to drain energy from other beings to survive.

Android 20 (AKA Dr. Gero)

Dr. Gero is the heart and sole of the original Red Ribbon army. When Goku destroyed the entire army when he is was child, he decided to build a android that had the power of a whole army. All the androids above were built by him. His most powerful creation is Cell.

Barta

He is the fastest member of the Ginyu force. The is known as one of the fastest person in the universe before Goku shows up and proves them wrong. He usually teams up with Jiece for his attacks but he is still fairly powerful by himself.

Babidi

The arsehole that resurrected Buu. By himself he is extremely weak but he is advantage is that he can easily turn other people into Majin people. His top skills are that he can change the surrounding enviroments around people easily.

Bibidi

The most powerful magician of his time. He created the evil monster called Buu. Buu is so powerful that he kills 3 of the Kaoishins. The remaining one finishes Bibidi off in the end.

Bardock

The father of the most powerful Saiyan ever. When bardock was destroying a planet, a person on the planet cursed him so he could see the future. You can read about him here.

Bojack

This guy is in Movie 9 and is extremely powerful. He easily defeats all the Z warriors. He has dark green skin and you could say he dresses like a pirate with his bandana.

Bra

The 2 second offspring of Vegeta and Bulma. In the series she doesn't really do a lot. She is half saiyan but sure doesn't show it like pan who is only a 1/4 saiyan who fights as much as she can. I thought Bra would be more violent because of her fathers influence.^_^

Dr. Briefs

The great scientist himself. He created Capsule Corp and is one of the leading engineers and scientists around. Unlike Dr. Gero, he puts his skills to a good use. He is also the father or Bulma.

Mrs. Brief

Bulma's mother. In my opinion she acts a bit naive. She also seems to be always spoiling little kids like when Trunks is in a hurry looking for the Dragon Radar she tries persistently to offer him some food and drinks.

Brolly

The legendary Super Saiyan-Jin himself Brolly. He is extremely powerful and the reason why he and his father survived the explosion was because of his immense power. Brolly goes crazy and also wants to kill Goku because he was so weak and kept on crying which drove him nuts. He is in 3 movies, Movie 8, Movie 10 and Movie 11.

Bubbles

King Kai's pet monkey. Kaio Sama uses Bubbles who is used to the immense gravity on the planet as a initiation.

Bulma (Bulma)

The daughter of Mr and Mrs Brief, she was the second person to be introduced in Dragon Ball and was always searching for the dragon ball s in the original series. She has no fighting skills like the others, but she is a brilliant engineer and inventor. She later marries Vegeta and has 2 kids, Trunks and Bra.
