Born on Ord Mantell immediately after the Clone Wars, Major spent her formative years on scrapyards and hunting in the grasslands of the jewel of nowhere, where her parents had run away to be happy apart from the governments they spent so many years working for. She practiced with her father's guns, read through the old books he collected, spoke to many of the old clone wars veterans of her hometown, she practically devoured military knowledge from the time she was old enough to ask questions. And all the while she practiced building and fixing things among the old junkards of Ord Mantell, until one day in her own home she found her father's old armour. Strange, she assumed he'd have thrown it away, but it was badly damaged.

So she took it upon herself to fix it, at first to show off to her father and see if he wanted it, however she was caught sneaking the plates out of the house to her workshop, and rather than punish her, her father simply said "That old gear isn't me anymore, if you want to fix it, do it for you." And so she did, modifying the size to fit her much smaller frame, adjusting as much as needed to ensure it was ready for use, at first because she wanted to wrestle Savrips without dying but as the Empire encroached, and TIEs began to circle the skies of Ord Mantell, she took on a different plan. She knew her father harboured fugitives from the Empire often, including a jedi general (His own words), but that he was not interested in fighting anymore. However, she was, and wasn't afraid to tell him she planned to fight alone if need be. Knowing she was too stubborn to be turned away, she was instead led to a Cell he had contact with, because no one can win a war alone.

She took with her two of her best friends, a Twi'lek girl named Rin, who her father called "Slip" due to her size and stealthy nature, and a human they all called "Gauntlet" for her propensity to get into fistfights, though her name was Jira. After some basic Rebellion Training, they were sent on their first mission with a team of rebel operatives, a prison break, however over the course of that mission Rin was killed and Jira captured (Though it has since been revealed she survived, and now works for the Empire.

Parent: Major's father, CT-9165 ("Showoff") fought in the 327th Star Corps under Commander Bly and General Aayla Secura, until Order 66, where he watched his brothers gun her down, and though he was programmed to believe it was needed, his relationship with a young Pantoran diplomat, cemented after the war, gave him the time and security to realize that it had all been a setup. He taught Major well, and worked alongside rebel cells since the early days of the Alliance, however considers himself a washed up failure, leaving Major to restore the family image by taking the fight to the Imps for him.

Guilt: Major accidentally sent an old friend into the hands of the Empire, causing her to become an ISB Agent, and lost her other childhood friend during her first assignment with the Rebellion. She has to atone for both of those mistakes, as well as every death under her command, in the blood of tenfold Imps, or die trying.

Loss Prevention: The rebellion is strapped for men, and veterans fight harder and longer than bringing in fresh recruits after every mission. All perfectly pragmatic reasons for Major to excuse her real motivation. Suicide missions, sacrificing men for the greater good, staying and fighting a fight that will result in heavy casualties.... that kills her friends as well as her foes, and she considers each man and woman to die under her command a personal failure. While this has the potential to damage specific ops, the Rebellion knows that most of the time this move is as pragmatic as it is instinctual, and maintaining life is just as important, if not moreso, than maintaining victory.

"Stocky" would be a good way to describe a first impression of Major. She stands at 5'4" (162cm) and is densely muscled, which is usually hidden under her armour or heavy coat, with light blue skin covered in smatterings of small shrapnel scars and piercing violet eyes, and shoulder-length white hair usually in a long braid that falls over one shoulder, she usually carries a cocksure expression and stands with a relaxed confidence that somehow feels more military than the rigid stiffness associated with such a descriptor, she is always in control of her movements, her salutes strong and her back straight.

She usually is seen around wearing her customized ARC Trooper Phase 1 armour she took and modified from her father, replacing the 327th Star Corps yellow signifiers with Rebellion Red and splashes of tasteful blue, especially on the long Kama worn around the waist. This armour masks all of her distinguishing features when fully worn, though it cuts a distinctive and unusual sight in the galaxy in the modern day.

Outside of her armour she is usually in a Rebellion Officer's Uniform, revealing her right arm has a long diagonal scar running along the forearm. if ever caught out of uniform she wears a heavy jacket and gloves, and heavy boots to ensure people always hear she's coming.
