[Early life As a child, Powder had a good relationship with Vi, her sister, and her parents. However, when her parents died during a battle on the bridge between Piltover and Zaun, her and Vi were the only people left in their family. On that same day, Vander found the 2 siblings. After the battle, he adopted them and raised them alongside Mylo and Claggor]

[A few years later Vi, Powder, Claggor and Mylo venture into Piltover after getting a tip from Ekko regarding a Piltover citizen whom he had followed after he shopped at Benzo's. After finding the apartment, the kids loot the place and Powder discovers a box full of blue crystals. However, Vi hears Jayce and Caitlyn's footsteps and signals everyone to leave. Yet in a rush, Powder drops one of the blue crystals, setting off an explosion which blows up half the building. This notifies the enforcers and sends the kids on a chase through Piltover.]

[After the kids manage to evade the enforcers, they made their way back to Zaun with their stolen goods. They are stopped by a street gang led by Deckard, who demands they hand the bag over. Not willing to go down without a fight, Vi, Claggor, and Mylo take on the rival gang and leave the goods with Powder. Midway, Powder is chased by one of the gang members who notices the stolen supplies and she is cornered to the docks, where she tries to attack him with Mouser, though it sputters out and fails. Left with no other option, she throws the goods away, Which Accidentally lands in the ocean. As Powder manages to escape for good. Later, Mylo yells at Powder for losing the stolen goods and claims "she jinxes every job," though Vi silences him. Back at The Last Drop, the group is reprimanded by Vander for the trouble they caused in Piltover while Vi argues back, claiming that Piltover has plenty while they have nothing. Laying low To lay low, the group decides to hide in a run-down arcade. Mylo berates Powder for not being able to fix a target practice range; instead, she not only shows him how to activate it, but plays the range herself, showing Her excellent aim. Enforcers soon break into the arcade, and they run away once more with the help of Ekko. Later, several Zaunites gather at the Last Drop, and the group, including Powder, stands by a corner. They watch as several residents, including Sevika, claim they want to fight back, but Vander reminds them that Violence is not the answer, and that they "just have to stand together". The kids wonder why Vander still chooses peace, and Ekko informs them that Vander has a deal with the enforcers. While lounging in the basement of the Last Drop, the group is signaled by Vander that enforcers have arrived again. They hide on the ceiling, but Powder struggles to hang on; luckily, she manages to stay up top, and falls only after the enforcer leaves the basement. She decides to make more bombs, naming one "Whisker", and she shows them to Vi, who encourages her. Rescuing Vander Vi returns to the Last Drop, letting the group know what she saw, they begin to plan a rescue for Vander. Powder insists on joining, but Vi warns her not to and leaves her alone with a flare instead. Powder breaks down afterwards; in her breakdown, the Hextech crystals she'd swiped from the penthouse spill out of her bag, and she realizes that those were what caused the explosion. She makes her way to the docks with a monkey bomb loaded with crystals. She drops the monkey through the window and explosions are set off, killing Mylo and Claggor alongside several of Silco's goons; Vi and Vander are injured, Sevika loses an arm protecting Silco, and Singed's lab blows up with him inside. Powder makes her way to the entrance, only to find Vander dead and Vi extremely anguished, and in that anguish, she angrily calls her a "jinx" and leaves her sobbing.]
