O'Brien Family
Balance of Chaos

Jeremy O'Brien
-
Titles/Aliases: The Anchor, High-End Hairstylist, "Jeremiah" (only when he’s in trouble)
-
Legacy: Hailing from Dublin, Ireland, Jeremy is a world-class hairstylist whose path completely rewrote itself the night he bought a pint for a gorgeous Australian girl in a London pub. Having survived a highly toxic childhood under a fanatically religious mother, Jeremy carries deep scars from his past. He famously wore his family's traditional tartan kilt to a courthouse wedding just to spite his mother’s toxic demands, and later disowned his biological family on the spot to protect his sisters and the woman who holds his entire heart from their bigotry.
-
Personality: Warm, unflappable, and famously, unconditionally infatuated with his wife. Jeremy doesn't just love Livvie—he absolutely worships her. She is his soulmate, his "tech fairy," his entire world, and his reasons for breathing begin and end with her and their twins. While he handles massive celebrity client tantrums with easygoing charm, his easy smile drops the absolute second an outside force threatens his family or tries to drag up past ghosts to cause Livvie pain. His protective instincts are ironclad; if you cross his wife, his Dublin accent thickens, his dad voice drops, and he will unapologetically help dismantle you.
-
Key Relationships: Husband to Livvie; devoted father to twins Rose and Killy; best friend and confidant to Michelle Bradley; honorary brother to chef Trevor O'Sullivan.

Livvie O'Brien (nee Olsen)
-
Titles/Aliases: The Tech Fairy, "Teic Sidhe," Cranston Tech Security Consultant
-
Legacy: Originally a brilliant cybersecurity expert from a small town near Brisbane, Australia, Livvie is a civilian powerhouse who accidentally stumbled into the world of superheroes by successfully breaching Eltarian security protocols. Her unmatched hacking skills were so impressive that legend Billy Cranston recruited her as a specialized consultant to code ancient Celtic magic into the Morphin Grid. When a fanatical extremist group known as the "Prayer Warriors" targeted her family, Livvie unleashed absolute digital retribution, exposing their multi-city operations to the authorities.
-
Personality: Brilliant, fiercely independent, and a total digital vanguard. While she can effortlessly take down corporate firewalls and rewrite government infrastructure from her private office cave, she is notoriously banned from the kitchen for once managing to literally burn water. Livvie speaks with a unique, unmistakable blend of a deep Australian accent heavily warped by over a decade of living with her Irish husband.
-
Key Relationships: Wife to Jeremy; fiercely protective mother to Rose and Killy; close ally to Billy Cranston; part of the cutthroat "unholy trinity" of protective mothers alongside Amber O’Sullivan and Gina.

Killian "Killy" O'Brien
-
Titles/Aliases: "Ki Ki", The Little Observer, The Pattern Prodigy
-
Legacy: One half of the O'Brien fraternal twins, Killy is a quiet anomaly in the family tree. At just two and a half years old, he shocked both his mother and legendary Ranger tech specialists by demonstrating a subconscious ability to look at hyper-advanced alien code or complex Celtic magical layouts and instantly point out pattern deviations. His unique mind allows him to see geometric alignments that completely evade standard human eyes.
-
Personality: Methodical, hyper-precise, and remarkably serious for a toddler. Killy craves symmetry and absolute order in a chaotic world. Whether he's monitoring his father's toast to ensure it's a perfect shade of golden brown, declaring that "butter needs straight lines," or meticulously sorting his silver and carrots into neat zones, Killy is the literal anchor of order to his twin sister's chaos.
-
Key Relationships: Son of Jeremy and Livvie; twin brother to Rose; favorite little apprentice to his mother's tech work and his Uncle Trevor's kitchen plating techniques.

Róisín "Rose" O'Brien
-
Titles/Aliases: The Chaos Fairy, "Ro Ro," The Whirlwind
-
Legacy: The other half of the O'Brien twins, Rose was born with an overabundance of her mother’s wild, bohemian spirit. She is famous for her legendary "fairy energy," which has caused literal domestic panic. After "The Potion Incident"—where she silently escaped her crib at dawn to mastermind a multi-room trail of absolute destruction—her parents were forced to install a prison-style, door-length security gate at her room just to ensure the household could sleep safely.
-
Personality: Bubbly, fiercely dramatic, and delightfully mischievous. Rose commands the room the second she walks in. She views the entire world as her personal stage, regularly turning sports practice into interpretative fairy dances and using full-blown toddler tears as a tactical delay method. She has a deep love for glitter—once completely ruining her brother's cast by dumping a bottle of craft sparkles down it, forcing an emergency trip back to the hospital for a replacement.
-
Key Relationships: Daughter of Jeremy and Livvie; twin sister to Killy; absolute darling of her "Da"; best friend and toddler partner-in-crime to Tomi Bradley and Tiffy Jordan.

Susan "Sosaidh" O'Brien
-
Titles/Aliases: The Reclaimed Sister, Little Susan
-
Legacy: As Jeremy’s younger sister, Sosaidh bore the brunt of her mother's fanatical religious control, which almost trapped her in a cycle of domestic abuse with a man named Seamus under the guise of "God's will." For years, she stayed passive, desperate for her family's conditional acceptance. Her life fundamentally shifted when she broke free from her mother's orbit, embraced her true self, and fell deeply in love with Abby. Her journey culminated in a stunning maritime wedding where she triumphantly walked down the aisle on her own terms, backed by her big brother and a chosen family that loves her unconditionally.
-
Personality: Resilient, deeply emotional, and fiercely evolving. Sosaidh has shed the skin of the passive girl who needed everyone else's protection, stepping up as a strong woman who knows exactly who she is and what she wants. While she naturally possesses a big, expressive heart and a gentle disposition, she has developed a powerful boundary line when it comes to keeping her toxic biological family away from the beautiful, honest life she has built.
-
Key Relationships: Wife to Abby; younger sister to Jeremy and Alan; sister-in-law to Livvie; doting aunt to Rose and Killy.

Dr. Abby O'Brien (nee Winslow)
-
Titles/Aliases: Marine Biologist, "Abs"
-
Legacy: Abby is a brilliant marine biologist whose deep love for the reef initially kept her on research boats, but her true legacy is as the emotional anchor of the group. Long before she joined the O'Brien family by marriage, she was Livvie’s college roommate—and the literal sister of her heart who stepped in and saved Livvie from absolute despair after a tragic accident claimed Livvie's parents. When the O'Brien family drama escalated into high-stakes thrillers, Abby stood as the unyielding vanguard, keeping the household safe and supporting Sosaidh through every wave of emotional fallout.
-
Personality: Pragmatic, fiercely protective, and the ultimate calm in any emotional storm. Abby cuts through pretense and religious hypocrisy with deadpan, logical precision. She is a natural caregiver—whether she's looking after her research students, cooing over her beloved fur babies (Sunny and Chewy), or coordinating with the rest of the chosen family network to ensure a perfect, safe haven for the people she loves.
-
Key Relationships: Wife and protector to Sosaidh; life-saving best friend and sister to Livvie; sister-in-law to Jeremy; favorite auntie to the twins; close colleague to professor Saoirse Riordan.
