Selina is brilliant and well, she knows it. She swears she is the smartest of her family, something they tend to scoff about it, and does not suffer fools lightly. Manipulative to a degree, Selina has a way with words and the ability to wrap even some of the smartest people around her little finger. She tends to lean more towards moral ambiguity more than her other siblings and often does wrong things for the right reasons, a fact that irritates Bruce to no end.

She is the type willing to get her hands dirty when it proves necessary and holds little remorse for this fact, preferring not to burden herself with unnecessary guilt. While she might argue with her siblings she is loyal to all of them and is that one person they all have fallen back on for help at least once in their life.
