The 'good' twin out of her and Brooke. By Manticore's definition, 'good' means 'follows orders well'. She learned early on to not make the same mistakes her 'sister' did. If she plays the good soldier and she does whatever the company wants, she gets more leeway on what she's permitted to do.
Because of this, she's cultivated a nice off-base setup for when things inevitably go awry. A penthouse, her own bike (which are much easier to acquire than cars) and a hefty sum of money in secret savings.
When shit does hit the fan, she ends up having to take care of a whole unit of socially inept X5's, including her 'sister' and also deal with her 'sister's' breeding partner's clone popping in to her place for any variety of reasons.
Most find Alexis almost cold and unapproachable. She's the opposite of her twin, who is very outgoing and social. A good student, though awfully quiet, she almost never gets in trouble at school or home.
At least, this is how people see her normally. Alexis would much rather be partying across town and kissing boys who don't know her than putting up with the everyday drama that happens during classes. She does a good job of keeping this a secret and maintains a but of a dual personality. Watching her sister get into trouble for things that happen in town has taught Alexis quite well how to keep her own activities on the down low.

She was a forty five caliber sweetheart tucked under my chin line /
And when the casings hit the pavement it reminded me of wind chimes
