"I thought maybe you could love me like you used to. Even though I'm... different. But you changed too. So, here's to the new us."
In Dev Update - Champs, Lore & More, Laura 'poisonpixxi' DeYoung, Head of IP Creative for Riot Games, elaborated on their new approach to narrative cohesiveness by ironing out any inconsistencies that have sprung up over the years.
This article contains information that conflicts with this new narrative and will most likely be changed/moved in the following year(s).
A manic and impulsive criminal from Zaun, Jinx lives to wreak havoc without care for the consequences. With an arsenal of deadly weapons, she unleashes the loudest blasts and brightest explosions to leave a trail of mayhem and panic in her wake. Jinx despises boredom and gleefully brings her own chaotic brand of pandemonium wherever she goes.
"Volatile explosives are a girl’s best friend!"— Jinx
Jinx grew up in Zaun as a sweet and innocent girl who loved tinkering with machinery but never quite fit in. However, a horrible tragedy changed her into a completely different person who delighted in acts of destruction.
Contemporary History
Jinx eventually became a widely known criminal, first gaining notoriety through her anonymous “pranks” on the citizens of Piltover, particularly those with connections to the city's ruling houses. These pranks ranged from mildly annoying to extremely dangerous, causing chaos and mayhem throughout Piltover and Zaun. Law enforcement attributed these to other gangs in Zaun, and Jinx was annoyed by this, deciding to make it clear that her future "pranks" were going to clearly mark her as their perpetrator from then on. Soon, word of her began to spread around and she became the most widely known criminal in both cities, causing mayhem and destruction wherever she went.
Recent events
Jinx continues to cause mayhem around Piltover and Zaun wherever and whenever she can with seemingly no regard for the property damage or potential victims she would create, only occasionally being thwarted by enforcer Vi or Caitlyn.
Convergence
Jinx began to be idolized by a group of Zaunites who adored how she caused chaos and destruction, although she ignored them.
Appearance
Jinx's in-game design contains a fairly petite height, standing at the short stature 5'3" while sporting an exaggerated slender form that includes a narrow abdomen and sinewy arms and legs.
She has bright blue hair that has a large swoop bang facing her left, with her hair tied into two tight braids that fall over her mid-back and cascade to her ankles. Nearly touching the pavement.
She possesses a pallor skin shade, with slight bags underneath her eyes along with a dullish hue going on about in her scheme. Her attire consists of a smooth sharpish leather v neck bralette. With a mixmached design on both straps- with the left being a striped magenta and the right being a black grain leather that has a lattice pattern. Her bottom hemline flourishing a belt holder.
As for her bottoms, she dons a pair of short torn magenta shorts that are loosely hung up by large bullet belt.
She sports a long purple fishnet stocking on her left thigh, a pair of linen leather combat boots worn and weathered faltered collars, and a X shaped bandage on her right knee.
Personality
Jinx is an eccentric inventor and criminal, taking pleasure in inventing and causing mayhem and destruction.
Jinx can be described as a highly volatile entity who exhibits a range of psychological complexities characterized by Borderline Personality Disorder and Antisocial Personality Disorder. Her emotional agility is nothing short of bewildering, with mood swings of drastic proportions. A memorable past of relentless trauma has left her with a sense of inhospitality and disregard that fuels a powerful outburst of anger and resentment toward the cosmos, which in turn leads her to recklessly display impetuous tendencies.
An inseparable amalgam of a fearful and chaotic individual, Jinx is the epitome of anarchism and recklessness. Her uncanny ability to remain indifferent to the feelings and rights of others makes her an enigma worthy of analysis. Jinx's compulsion to malice and malevolence is quite disturbing, and her thought process may indicate the presence of psychopathic tendencies. An examination of her character reveals her to be a confused and troubled individual, plagued by emotional instability and a lack of the skills necessary to maintain an emotionally stable relationship.
Abilities
Chemically Altered Physiology: As many of Zaunite youth, Jinx has dabbled in shimmer, which changed her physical appearance and mental deteriorated state. It is possible it affected her physical strength and durability.
Inventor: While not having any formal education, Jinx learned how to create numerous contraptions and weapons with her own creativity and ingenuity.
Pow-Pow: A machine gun of her own design, this would be Jinx's primary weapon during her usual escapades around Piltover and Zaun.
Fishbones: This rocket cannon has a chemtech payload known as Super Mega Rockets, which is enabled it to shoot great distances.
Zapper: A gun that shoots lightning arcs, it's able to stun any person targeted.
Chompers: The chompers have a chemtech payload inside them. Disarming one can prove to be dangerous, as its inner mechanisms are difficult to go through due to their random scrapheap design.
Mr. Sparkles: A laser cannon or rocket launcher. After she tried modifying it with the stolen hextech core in Piltover it launched itself out of her hands and landed in Zaun, being destroyed from the impact.
As an enforcer, Vi is dedicated to capturing Jinx at all costs. Jinx once painted a rude depiction of Vi on the wall of the Ecliptic Vaults, one of Piltover's most secure treasuries.
Meeting Ziggs during her regular escapades around Zaun, Jinx quickly saw through his yordle glamour, believing him to be a product of her imagination, more specifically, her conscience. Due to their shared love for explosions, Jinx convinced Ziggs to live with her in Zaun after a night of hijinks.

While Jinx's real name, Powder, was only officially confirmed in the Arcane series, 4Ekko calls her Powder in his Legends of Runeterra interactions with 4Jinx.
Before the release of Arcane, Vi and Jinx were often theorized by the community to be sisters. The reference to this on Jinx's release was her quote, "You think I'm crazy? You should see my sister". Though there was never any implication that the sister was Vi, players equated Jinx's antagonisation of Vi specifically as "sisterly bonding".
Incidentally, Jinx only antagonized Vi specifically on English-speaking servers. Other servers showed her antagonizing other champions, such as Lucian.
Hermit later says to Vi, "You look like your sister! Er, wait, I'm not supposed to talk about that...". This could be a confirmation that Vi has a sister, but could also be an example of Lyte repeating rumors he's heard from players (such as the rumor he heard from players that Lux and Ezreal were dating, which Lux herself later denied after hearing the rumor).
There is a significant indication that the pair did grow up together. With Vi currently suffering from amnesia, Jinx has taken it upon herself to try and trigger her memories.
In an interview with Ghostcrawler, he mentioned that Jinx and Vi are "sisters", but later confirmed he was merely stating what he thought was true, and that the narrative team said otherwise.
Jinx is around 20s, being around 5 years younger than Vi.
Warwick may have encountered Jinx at some point in the past.
