If we are still sharing our Shepard/Liara stories, I made a new Shepard yesterday.
Amelia Shepard Colonist/War Hero
Devastated by the loss of her family on Mindoir, Amelia joined the Alliance and vowed to one day make those responsible pay for the murder of her family. Upon joining the Alliance, it was discovered that she had biotic potential, and she immediately underwent the implant surgery, then rigorous biotics training. She eventually became the strongest biotic in the Alliance. This fact coupled with her 'War Hero' status, gave her some leeway with the Alliance brass, and she often avoided punishments for insubordination.
As for morality, she is fairly Renegade. She believes eliminating wrongdoers takes precedence over saving innocents. Her MO is to make the galaxy a better place by eliminating the wicked....she is similar to Samara in a way, but she follows her own Code instead of one created by others. She would never harm an innocent for her own gain, but will if she can eliminate a terrorist (she will kill Balak and sacrifice the hostages, for example). She distrusts aliens, but also humans. She is just a biotic ball of anger and hatred, fueled by what had happened to her as a teenager on Mindoir.
Amelia does eventually develop feelings for Liara, even though she wasn't too fond of her in the beginning, and didn't trust her. She is drawn to Liara, since she is the only one on the team that really questions her moral judgments...that makes her think about some of the things she has been doing these past years. This frightens and angers Amelia at first, but she grows to respect Liara for it and then finds it even endearing. Not only Liara's strength and courage, but her compassion and empathy for others drew Amelia to her.
