Usagi, sans the drama surrounding her abduction, which is mainly irrelevant since she didn't know about it till recently, was a military brat. So she had a pretty strict upbringing. However, her father was away a lot, for very long periods of time. Despite her mothers attempts to rein her in, Usagi was one of those 'daddy won't pay attention to me, maybe he will' types.
It stuck pretty much through out her adulthood, and still continues today even though that guy is dead now and she's not really in contact with her biological father.
If we're talking about actual POWER as in 52,000 SP in Vulcan Nerve Pinch, then Usagi also has a decent amount of that as she was accepted into and trained by the CN/SWA 'elite special operations academy.' She graduated from that prior to being certified capable of receiving capsule implants.
Essentially out of her pod, Usagi just acts pretty much like she did when she was in school. She was more reserved for a while, but :drama: and now, primarily because she's high as a kite 24/7 (she's even doped up during down time...) Her main 'egger' tendencies are mainly spending money like she has an unlimited supply (because she essentially does) and walking around with an smug sense of invincibility.
I think I got the jist of posting down now.
