Yeet I love this character so much So I actually already have a story/world that I could incorporate her into, Basically, it's set in a futuristic alternate universe thing, where there are tons of large-scale wars decimating the population, so they're fought by genetically modified soldiers instead of 'real' people. Nitro isn't a soldier, she's an experiment. Instead of just making soldiers stronger or faster, the Confederation is trying to make them control fire. Nitro is the first experiment who wasn't killed by her own fire. She's kept in a facility to test her limits and 'train' her. Unlike the other mass-produced soldiers, she's a special little experiment, so she won't just be killed when she shows rebellious behavior (which is almost always). So her whole life's goal as been to try to escape to the wastelands/wilderness, which is what most of the world is now because of the wars. The part of the story that I already had follows three regular soldiers who find a reason to hate the Confederation and escape somehow. And maybe they'll meet up with Nitro once both parties are free. It's a work in progress, like most of my stories. This scene shows Nitro jumping through a window, crossing the 'point of no return' into freedom. That fire in the background is hers.
Music - Point of No Return by Starset The lyrics fit the scene, if you listen. I used the watercolor brush in Medibang Paint Pro for the fire, in case you're wondering. Her name is not copying anyone else's characters, it derives from the word 'nitrogen', which is an element on the periodic table of schience shtuf
