If we're getting another mechanical expert with scanning technology and enhanced strength that kinda rules out all three of my possible characters. He's also the son of Village scientists which matches Trixie's background too.

Perhaps I should switch out to play as a medical specialist, such as a field medic who can help patch up the team if they get injured? She would have come from outside the Village, a survivor who had been rescued from an enemy attack after having been part of a small group of wandering refugees and had learnt her medical knowledge through trial and error field experience under the guidance of an old mentor.
