Rio has issues with secrecy and lying which are never fully explained, but it is those issues which make Jerrica reluctant to reveal her masquerade to her long-time boyfriend for fear that he will feel betrayed and made a fool. Rio has a hair-trigger temper, and is disgusted when he discovers Kimber made the same date twice with two different men. He attacks her verbally, which sparks a fight between him and Jerrica, who decides based on his behaviour that she cannot reveal her secret (Glitter and Gold).

Although extremely jealous at the time Jem spends with other men such as Johnny Deacon, Red Johnny Mack, and particularly Riot, Rio does not seem to equate his own behaviour—seeing both Jerrica and Jem romantically simultaneously—with being unfaithful. he is even more confused in Greece when he meets a stranger and immediately is drawn to her, unaware that she is Jerrica in disguise (Midsummer Night Madness). After saving her life, Rio develops a tentative friendship with Minx, bonding over his desire to build a synthesiser. However, when Minx builds it for him, they argue and she goes back to the Stingers (Change of Heart).

He directed The Misfits Hit it Big, run a film studio (Starbright), run two music companies, and his fortunes have yo-yoed, going from wealthy to destitute, mainly due to his relationship with the Misfits (Rock Fashion Book). In an effort to remove himself from the position of being under Pizzazz's thumb, he bought out Harvey Gabor's shares of Misfits Music with the intention of renaming it Raymond Records. He then immediately offers Rory "Riot" Llewelyn half of the company, which is renamed Stinger Sound, in order to ensure the Stingers sign with his label (The Stingers Hit Town). However, despite his live-hate co-dependant relationship with Pizzazz, he cannot seem to rid himself of her completely. Their lives continue to come in constant contact, a fact he sometimes bemoans, and other times blesses as it offers him new opportunities to make it big (or go broke). He often treats Pizzazz like a wild and wayward daughter, with a mixture of genuine fondness and barely disguised contempt. And he perfectly happy to continue to manipulate her, if he can get something out of it.

Eric a schemer, a liar, and a manipulator out to amass money and power any way he can. However, he draws the line at murder, and even warns the Holograms when Lexa, the Regent of Mordavia, planted a bomb on stage set to go off during the Holograms command performance (The Princess and the Singer). he usually hires people such as Zipper or his pet genius, Techrat, to do his dirty work, rather than getting his own hands dirty. However, Eric also seems to have genuine admiration and respect for Techrat, referring to him as a genius (The Music Awards). Eric is obsessed with regaining control of Starlight Music, and has a rivalry with Jerrica Benton that has long since passed from professional into personal, bordering on genuine hatred on both sides (Out of the Past). He has tried gaining control of Starlight through Kimber Benton by offering her a solo recording contract, appealing to her vanity, and then finally by outright trickery through promoter Dave Daniels offering her a contract designed to force her to forfeit her Starlight Music shares if she and Stormer failed to produce a hit album (The Bands Break Up).

While performing with his band in Venice Beach, Sean asked Kimber to write a song for him, angering a jealous Pizzazz who tricked him into an interview with Cool Trash magazine which quoted him out of context (Scandal). While shooting a science fiction film for Howard Sands with Jem as his costar, Sean was injured attempting to perform his own stunts and impress Kimber, who had become engaged to stunt man Jeff Wright. Sean broke up Jeff and Kimber's wedding by sending Rio as his proxy with a counter-proposal. Kimber then broke off her engagement(s), stating she was too young to get married but that when she is ready, she will marry Sean (Hollywood Jem).

Harvey befriends Kimber Benton at Christy's Stables, when the girl is thrown from a horse. He opens up to Kimber and the rest of the Holograms about his relationship with his daughter. His first instinct, upon hearing about the trouble she causes the band is to pull out his chequebook and pay for the damages. He claims to not be able to do a thing with her since her mother walked out on them years ago but it is obvious that, for all her careless ways, Pizzazz truly wants his attention far more than his money. Pizzazz feels betrayed when he flies the Holograms to Mullberry in his private jet, choosing to spend Father's Day with Kimber Benton instead of his own daughter. Kimber encourages him to try and connect with his daughter, but they argue and Harvey gives up without a fight (Father's Day).

Emmett was crushed when his wife, Jacqui, was killed in a plane crash in 1979. A brilliant engineer, Emmett began working on a computer to be used to re-create musical performances using life-like holograms. He named the computer "Synergy" and programmed it with the recordings and likeness of his late wife, Jacqui. However, he quickly realised that Synergy was much more than he had originally envisioned, and the potential for the holographic computer being used as a weapon was too great. Using the profits from Starlight Music, he purchased the defunct Starlight Drive-In, where he constructed the computer in secret. While working on the super computer, his health began to fail. He hired a young music executive, Eric Raymond, to manage the day-to-day operation of Starlight Music.

Before his death, he realised there was no way he would complete the patents on Synergy in time. He constructed a pair of remote holographic projectors in the form of a pair of earrings. He also purchased costumes, instruments, and a car, and had them hidden in the drive-in, and made arrangements for the earrings to be delivered to Jerrica. He willed half the company to his daughters, and half the company to partner Eric Raymond, unaware that Eric was embezzling from the company.
