HI! It's Foster/Dodger here! I am excited you're here! I got my three:
Deke Sun-Crichton:. He's the son of John Crichton and Aeryn Sun (if you do not know, those are two of the original crew of Moya from Farscape). He's kind of the expositional guy around here, explaining the ship, the universe, and keeping people from annoying Pilot too much. He's still pretty young (20s), but he has a tendency to act a little older. He's also tech-savy and a decent pilot. Probably (definitely) the closet in age to Cindy here.
Bucky Barnes (MCU):. Bucky currently thinks he was last awake in 1945 thanks to our current plot, so he's a bit...lost. BUT he comes from post TFATWS and was settling in until then!
Carol Danvers (MCU):. She comes from after Endgame and is also settling in, the newest arrival. ;)
