Jet, known on his home satellite as the "Black Dog" for his tenacity, is a 36-year-old former cop from Ganymede (a Jovian satellite) and acts as Spike's foil during the series. Physically, Jet is very tall with a muscular build. He wears a beard with no mustache, and is completely bald save for the back of his head. Spike acts lazy and uninterested, whereas Jet is hard working and a jack-of-all-trades. Jet was once an investigator in the Inter Solar System Police (ISSP) for many years until he lost his arm in an investigation that went awry when his corrupt partner (and friend at the time) betrayed him. His arm was replaced with a cybernetic limb (later revealed to be by choice, as biological replacements were possible, he wanted the fake arm as a reminder of what happened), yet his loss of limb 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. As a character, Jet is the quintessential oyaji or "dad" even though he often wishes people would view him as a more brotherly figure (so as not to seem old).
In a later episode, another Vicious/Spike parallel is set up when Jet finds out that it was his old partner Fad who betrayed him (though in Jet's case, there was no love affair involved). Fad arranged for Jet's death in a setup, but he survived with only a missing arm and a scar on his face. It is worth noting that Jet managed to face the demons of his past and let them go, in contrast to Spike, who was killed when he confronted his. This is likely due to the contrast in the two approaches to the past. While Spike hid and fled from his past, Jet tracked it down and confronted it.
The class president in Toru's class (1-D), he is a highly respected member of the school: due to his much-revered older brother and his own excellence in both academic performance and character, he is referred to as "Sakamoto-sama" by his peers regardless of their seniorities, and all students bow when they see him, though he feels somewhat intimidated by such reverence. For pretty much the same reasons, he has been hand-picked by Arisada as the next in line for the student council president and has on quite a number of occasions shown great leadership skills.

In the SAC universe it is shown in that Hideo Kuze is the first person she ever loved, and her relationship with Batou seems to be one of a close platonic trust.
Like Yumi, Shimizu has had a negative experience with persocoms: her husband bought a persocom and eventually she became unimportant to him compared to the persocom. He spent more and more time with his persocom until he forgot about his wife completely, locking her out of the house one night because he was so enamored with it. Because of this, Shimizu was no longer able to trust human men.

At first, Takumi was not part of any team (he was just loosely affiliated with the Akina Speed Stars), but later, Takumi joins Project D, a super-team created by Ryosuke Takahashi aimed at capturing all the time records in Japan. But despite this, he has yet to beat his father in a race.
Along with Jheese, Butta sits out the fighting until Gokuu arrives and defeats Reacoom singlehandedly. Butta and Jheese jump in to attack Gokuu, but the Earth Saiyan proves both faster than Butta (much to his fury) and stronger than both of them. He then defeats Butta with two crippling blows to the back, and shortly thereafter, Vegeta finishes Butta off by dropping a knee on and breaking Butta's neck. He and Jheese fought Tenshinhan when they tried to invade North Kaio's planet in an anime filler, only to be defeated. He was once again defeated later by Gokuu.
