Black Powder's usual personality is probably the most normal among all the Crossbones, even compared to Malie, and she overall carries the vibe of not quite a good person, but not quite somebody outright evil either. One can easily get the idea that she would have turned out a nicer, more moral person had her parents not abandoned her to Scum City, but her experiences on the island have instead made it so that while she lacks a moral compass, she's not a fundamentally bad person either. Indeed, she even often regrets that she has to fight or attack certain communities she feels aren't quite deserving of what will happen - but also doesn't hesitate in the least, as she's come to see the Crossbones as her family, and will do anything for said family, no matter how dark - not aided by how most of the Crossbones treat her rather well, even if Absynth is rough towards her like usual and, at least early on, Akane is suspicious that she's not completely committed to the Crossbones' cause. She values the other Crossbones without exception however, even Absynth, as she admires Absynth's assertiveness and strength, and often spends a lot of time with Malie, owing to how they're both the only Crossbones useful for deception and how they're both young girls as well, to the point you'd almost wonder if there's something between them - and indeed, there may be, however it is rather unclear. Black Powder is homoromantic, though it's hard to tell what sexuality she is, though it overall leans closer to asexual, but this comes up only very rarely in the story itself, mostly with regards to Amber, who she had quite a crush on during her time infiltrating the village, and while that came and passed, it's clear she still cares about her to a degree, disliking facing her and wishing Amber would join the Crossbones so she wouldn't be forced to attack her - a source of rare hesitation Amber often exploits to deal with Black Powder, even if she too regrets how things ultimately ended up. Despite how Akane is suspicious of her early in the story, she does look up to her and sees her as a role model, wanting to be as strong, willful, and full of personality and presence as the leader.
