Few know the true Sheridan Alder, but if there’s anything you should know it’s that she’s caring and intelligent. Of course she’s also responsive, ambitious and confident, but they’re often slightly tainted by a mindset of being a bit pessimistic in certain occasions as well.

Strengths & Weaknesses

Her caring nature though, this is what she’s so well-liked for. Comrades frequently count on this and her incorruptible nature especially when they need comforting or support. Though she takes her job sometimes a bit too serious, Adler is known to let her hair down once in a while which can be quite surprising for those around her. She maintains an active lifestyle and will always give something new a go. She has been described as being fearless, passionate and reckless, her fearless and passionate traits also makes her narrow-minded while she undergoes a mission. Her focus is on the mission objectives, instead of including the people around her. She has been working on this since being promoted to a First Lieutenant.


Determined to walk on at least fifty alien worlds before she retires, Sheridan has planned a long lasting career ahead of her.
