Flaws // Virtues
Virtues: Focused: This doesn't mean that Niki tunnel visions but when she's doing something, she's devoted to that task. She's not one to procrastinate and tackles things head-on. Better to get it done and move on than let it sit as a reminder of something left to do that's only 90% complete.
Decisive: Rarely is she wishy-washy about anything. Give her choices and she'll pick something, ask an opinion oh she has one. If you need someone to decide between this or that, Niki is your girl.
Confident: Looking on the bright side of things, not really but for the sake of things, she'll go with that. She can be 100% confident that things are going to fail. But ultimately, it is what she views as a sign of a good leader and because of this Niki will use her confidence to try and help bolster someone else confidence in themselves and remove whatever doubt they were feeling.
Flaws: Competitive: Everything is a competition, even if you don't think it is. She has been alone for a very long time and perhaps it is a way of validating her existence since her world died. Either way, she has a need to one-up others and doesn't lose graciously.
Headstrong: Nikita will take others' advice into consideration. But at the end of the day, she's going to do what she wants. For centuries she has taken the role of Senshi, guardian of her homeworld, to heart, and views herself as a leader and carries the weight of her decisions be it positive or negative. If she asks someone their opinion that's one thing. But if she didn't, well be prepared to be told that their advice was not warranted nor needed.
Aggressive: She has quite a bit of pent-up emotions, not like she's had anyone to talk to for quite a while. Inadvertently this means she has a bit of a short fuse and can trigger easily. Sometimes this can manifest as a physical reaction which might not be that bad when powered... but it is why she's taken up MMA fighting. Typically it's just verbal as she doesn't want to bring
too much attention to herself, however, she is unrelenting in her assaults when things escalate. She might not start a fight but she damn well will finish it.
