Here's the moms of each character in Galactiquest. (Except for Aiden. He doesn't know what his parents look like, and neither do I.) This picture is from a couple years ago, but I edited some details before posting here.
Tanya Allen - Doctor. Like her daughter, she was cheerful, outgoing, and very well-liked among peers and patients. Roxie doesn't have any memories due to her tragically dying in a tornado when she was only one years old. She was rumored to have a knack for sensing things to the point where it was borderline supernatural.
Santana Ibarra - Tech Support Worker. Aside from the buck teeth and brown hair, she and her eldest son Leon have few similarities. She's much more cautious and less clueless than Leon and his father, but wouldn't have it any other way. They have a strong relationship, and even though the idea of Leon going to space worries her half to death, she's happy that he's able to achieve his dreams. Unfortunately, she's in for a very bad time very soon.
Jung Hee Kim - Catering Chef. She's a very strong woman with some very strong insecurities that made her and her child's relationship... complicated. Things got even more complicated when Jun disappeared for months and came back making headlines for infiltrating the then-men-only space military branch. Their relationship is better now, mainly because Jun took it upon themself to help her work through some things. But to be honest, they still don't trust her enough to open up about any of their problems.
Delilah Rose - Theater Actress and Washed Up Local Celebrity. She's a mother of 6 and struggles to put food on the table for the 5 at home, but you wouldn't be able to tell from her lifestyle. She lives like she's perpetually 25 (and wants people to believe that ;>) If it weren't for Mia managing finances and the family, they'd be in a worse place than they already are. Needless to say, their relationship? Not great. Delilah doesn't know, though.
Rosa Alverez - Freelance Journalist. She's a little sad she doesn't get to see her sons regularly, but other than that, she's living her best life. She and her younger son Emil are like two peas in a pod. She lovingly spoils him, then lovingly jokes that he's spoiled. Since they're more alike, he feels more able to open up to her than his brother and father. Her older son Lorenzo, on the other hand... He didn't take the divorce nor her remarriage well, and has been kind of closed off from her ever since. She's convinced he'll come around eventually. Also, the flower on her suit is one of those novelty flowers that shoot water. She gets one of her sons with it every time they come to visit.
I wish I had more pics of each character with their parents, but I only have Jung Hee + Jun and Rosa + Lorenzo & Emil
