The inspiration for Spike's martial arts is found in Bruce Lee, who uses the style of Jeet Kune Do as depicted in Session 8, "Waltz for Venus".
He has fluffy, blackish green hair (inspired by Yūsaku Matsuda's role as Shunsaku Kudō in Tantei Monogatari)[3] and reddish brown eyes, one of which is artificial and lighter than the other.
A recurring device throughout the entire show is a closeup on Spike's fully natural left eye before dissolving to a flashback of his life as part of the syndicate.
The purpose of this cybernetic eye is never explicitly stated, though it apparently gives him exceptional hand–eye coordination – particularly with firearms (Spike's gun of choice is a Jericho 941, as seen throughout the series).
During the course of the series (set in 2071), Faye crosses paths with Spike and Jet twice and makes herself at home aboard their ship the second time around, much to the consternation and disapproval of the two men, both of whom have their own reservations about women in general.
She has many bad habits, such as drinking, habitual gambling, smoking cigarettes and occasionally cigars, becoming unnecessarily violent, and turning on partners when the profits seem too skimpy.
Upon awakening from her 54-year cryogenic sleep, not only was she saddled with a massive amount of debt that she had no means to pay, but she was also diagnosed with total amnesia, a stranger in a mysterious world that she was not a part of and did not understand, surrounded by people who claimed to be helping her but were only there to take advantage of her naiveté.
Utterly betrayed by someone she thought she could trust after waking, Faye found herself burdened with even more money to pay, and the situation resulted in the hardening of her personality to an extreme degree.
His loss of one of his limbs coupled with the general corruption of the police force prompted Jet to quit the ISSP in disgust and become a freelance bounty hunter.
Jet also considers himself something of a renaissance man: he cultivates bonsai trees, cooks, enjoys jazz/blues music (he named his ship the Bebop, referring to a type of jazz), especially Charlie Parker, and even has interest in Goethe.
"Radical Ed" could be considered a "free spirit"; she is fond of silly exclamations and childish rhymes, is easily distracted, has the habit of "drifting off" from reality sometimes in mid-sentence.
Ed's generally carefree attitude and energy act as a counterpoint to the more solemn and dark aspects of the show and is the anime's primary source of comic relief.
Her father, Appeldelhi Siniz Hesap Lutfen, recognizes her immediately by her birth name of "Françoise Lütfen" and while initially unsure of her sex, leaves shortly after to continue his unending quest to document every asteroid that falls to Earth from the wreckage of the Moon.
In the manga, she was a friend of a timid young boy in the orphanage known simply as "Tomato" (the name given to her PC in the anime), who, like Ed, knew a great deal about computers and the net.
The original character design appears in session 5 as a young boy that steals an adult magazine from Annie's bookstore by smuggling it under his shirt which eventually he takes out and reads.
Over the course of the series, Ein answers the telephone, steers a car, uses the SSW, plays shogi, operates the "Brain Dream" gaming device (to hack a supercomputer in a few seconds), and generally performs tasks that an average canine would not be able to accomplish.
It takes place immediately after Mao signs a peace treaty with a rival crime syndicate, the White Tiger, expressing a desire for relief from the hypervigilance of gang warfare.
Although his precise motivations for enlisting are debated, his testimony helped frame Gren, his squadmate in the war, for spying, which raises the possibility that he himself might have been involved in military espionage on behalf of the Syndicate and chose to pin it on his admirer.
Lin (リン, Rin) is a young and loyal member of the Red Dragon Crime Syndicate who is asked by Wang Long to accompany Vicious on a drug deal to the moon Callisto.
He appears in "The Real Folk Blues Part I" to rescue Spike and Jet from Syndicate assassins, which leads to him revealing Vicious's coup against the Red Dragon leaders.
He reappears in "The Real Folk Blues, Part II" during Spike's attack on the Red Dragon headquarters, aiding him in the running gunfight against the Syndicate minions.
After escaping from jail, Gren worked as a saxophone player at Rester House, a bar in a sector called "The Blue Crow", which is located on one of Jupiter's moons, Callisto.
Judy plays the stereotypical dumb blonde, and always appears in an open bolero jacket with nothing underneath, frequently wiggling her hips with excitement.
They make various claims about what they did before becoming old-timers, including bounty hunting, building the stargates, farming, piloting planes in a war, sinking the Bismarck, digging ditches, and crop-dusting.
In the film, they help Jet and Faye distribute the antidote for a deadly, hallucinogenic nanovirus by flying 20th-century era antique planes over Alba City.
Hex is a talented programmer widely considered to be a genius due to his long-standing hold of the Champion Seat of the CosmoNet Chess tournament series.
Watanabe added that he does not see this as a "particularly unique feature" of Cowboy Bebop: The Movie, and that all people have moments when they "lose our temper and want to destroy everything".
An ethnic Arab with a considerable amount of knowledge of "beans", he is really Doctor Mendelo al-Hedia, the man who developed the nano-machinery that was to be used as a virus for the military and vaccinated Vincent in attempt to keep it under control.
After revealing to Spike, in a later scene, the nature of the nanomachine virus and the vaccine given to Vincent, armed men show up and Rashid runs off, followed by the sounds of gunfire.
Mad Pierrot Tongpu (real name unknown) was part of an experiment to create the perfect assassin by a secret organization referred to only as Section 13.
