Not sure if Scuttlebutt is the right section for a thread like this, but, well...

Elena Shepard
Colonist and Sole Survivor. Infiltrator.
I decided to go with Sole Survivor because Colonist also deals with everyone around Shepard dying and only her escaping.
Mixing Mindoir with Akuze, I decided Shepard would be the kind of person who would value the lives of those she cherished since she went through two experiences where everyone around her died - all her afforts would be to prevent that from ever happening again. She would tend towards order, going for the most peaceful outcome available. At the same time, she would despise deeply people who played with other lives or that saw them as expendable, leading to harsh and violent actions towards them even when not necessary (i.e. whenever she crossed paths with a terrorist, a Cerberus member, "scientists" like Saleon, she would kill them even if other option was presented). Despite that, Shepard is a practical person, the kind that would sacrifice few in order to save many if necessary (as long as the said few were not people close to her, as that is her weak spot).
ME: Mostly Paragon, but with some Renegade decisions due to what was said above (Balak, Saleon, Kyle, the Cerberus scientist on Newton). Placed saving Wrex above anything, had a hard time leaving Ashley to die, allowed the Rachni queen to restore her race (the fact I love insects weighed on this decision...). She was eager to get close to the Normandy crew, even though she is not the most social person around. Kaidan was a big help on that and it was not without guilt she chose to save him in Virmire knowing her personal feelings were in the way.
Since she was not the outgoing kind, she found a closer friend in Wrex than in (the most friendly) Garrus.
Weapons of choice: pistols during almost all the time until she (well, I) found out how freaking amazing sniper rifles are. Too bad it was almost at the end of the game.
Armor: Medium Colossus. Love its colors.
ME2: After everything and with Akuze on her background, working with Cerberus was something that bothered her all the way. Whenever someone pointed out the fact she was working with them, that would hit her deeply.
Maybe (?) because she was suffering from having to do something in a way she hated, it was very easy for her to relate with Thane. At first she couldn't understand how he could push any responsability aside when she couldn't ignore the pain of having to work with Cerberus, but that worked out in a way to make them as close as possible. Thane's impending death was a shadow that would haunt her, though, as Shepard still had many scars from losing people close to her.
With Wrex away, Joker was the only friend from old times she had with her from the start and that led to a very close and intimate friendship - not that any of them would admit it, obviously.
Mordin fascinated her as if she met a grandfather with views completely different from hers. Even though that led to many conflicts in their talks, they actually became close friends in no time. Legion and Jack were other new members with which she had a especial connection, relating to their stories and always having them under her wings. Because of that, she ended up losing Miranda's loyalty when they were starting to get close. Hopefully, things went better with Tali.
Kept the Paragon disposition with not many Renegade choices, so her scars fade away naturally.
Armor: N7 with some modifications. As evident by her bleached hair, she likes yellow/golden tones, so her armor pieces were always dyed in those colors.
ME3: After bonding so much with her crew and almost having to kill it on a suicide mission for the bigger good (hopefully everyone survived), Shepard was starting to grow a bit arrogant. She felt like she was risking everything she cared for for the good of a galaxy that, putting simply, complained too much. Renegade choices became much more common, as a "Shut up and let me do my job" aptitude started to arise.
Kaidan coming back from the past wasn't something she was expecting, but after everything that happened with Thane she couldn't see Kaidan as more than a friend now.
Her friends help was very important soothing the stress she was going through, mainly after Mordin's death. Thane's death, however, was more than she could handle. Shepard went through a difficult period after that and that was evident in her behavior (killing a sick batarian terrorist almost immediately after that, punching Han'Gerrel and ordering him to leave Normandy, telling the quarian she would happily watch they be annihilated if they didn't accept peace with the geth).
The shore leave on the Citadel came as a much needed break for her. After Thane's memorial she finally peaced her heart and accepted his death. Once the party with her crew was over, she was once again the Shepard of old times and ready to face Cerberus and the Reapers one last time.
At the end... at the end... I don't know. I can't really see any of those ends as the end of Elena Shepard's adventure. But I like to think she died and met Thane across the sea as they promised.
During her imprisonment, she stopped bleaching her hair but still went with the yellow/golden N7 armor. Pistols and sniper rifles were her weapons of choice once again.
