Jet is the level-headed captain of the "Bebop." He is somewhat old-fashioned, enjoying activities that take patience such as tending to his bonsai trees and old strategy board games. Like an older brother, he looks after Spike whether Spike appreciates it or not. He acts as if he dislikes Faye due to his old-fashioned, almost chauvinistic attitude but he cares for her as well.

Jet was once a policeman nicknamed the "Black Dog" because of his reputation to never let go after "biting", relentlessly dedicated to bringing criminals to justice. His days as an ISSP officer  left him with a bionic arm and a scar on his right eye.

An old fishing vessel Jet bought second-hand on Ganymede shortly after he left the ISSP. She is the cozy home of Jet's rag-tag group of bounty hunters.
 

Faye is a tricky gambler but her slick skills are not enough to save her from massive financial debt. She cheats at casinos and behaves brashly in most situations. She acts as though she hates her shipmates but they are all she has in the world.

Three years before she stepped aboard the "Bebop," Faye awoke from cryogenic sleep with amnesia. The only record of her previous life is an seventy-year-old video recorded when she was an enthusiastic schoolgirl.

Sometimes referred to as "Radical Edward," Ed is an eccentric genius hacker from Earth prone to fits of ferocious beast-like rage when provoked and other displays of strange behavior. A longtime fan of the "Bebop" and its crew, she managed to follow their exploits with her computer until the opportunity to board the ship literally arrived on her doorstep. Ed adores her shipmates but Spike and Faye often tire of her. Ein is her constant companion.

Though Ein may appear to be an ordinary Welsh Corgi, he is in truth a "data dog" developed at an illegal research lab for purposes unknown.

Signs of Ein's true nature are demonstrated time and time again but his human companions never notice. He seems to be able to drive, answer phone calls, activate machines and even hack into computer systems.

Vicious is a ruthless top-ranking member of the "Red Dragon" crime syndicate. A loner by nature, it seems his only companion is a black-feathered alien bird. He mercilessly carries out the will of the syndicate's elders though his loyalty to the organization is often questioned. His values and beliefs, like is choice in weaponry, are old-fashioned and highly resistant to change.
 

Vicious and Spike were friends, rising together within the ranks of the syndicate before his girlfriend Julia fell in love with Spike.
 

A woman on the run from her past, once romantically involved with both Vicious and Spike. She has remained elusive, last spotted on Callisto.

She was the first to learn of Gren's personal connection to Vicious.
