I couldn't find what suited everyone fully (least to me) so I got as close as possible...now I need to go post cause between this and my own sibling I'm lagging behind a bit. Don't go off the deep end...I'll do what I can.
Runali
Runali's the captain who holds the fate of the entire crew in her hands, one wrong move or decision and the results could be catastrophic, yet she endures this with a cool and composed mentality which may come from confidence, with that she has her own share of mystery, thought something that was gentle but had a certain force behind it due to her authority would fit
Nolan
Nolan seems a gentle soul who looking for something on the sea, but I'd imagine it'd still bit lonely leaving behind Annie and his family so I thought something with a bit melancholy would fit but with enough energy to show that hidden determination that comes from his conviction. I listened to it wondering if he'd look at the blueness and think "I wonder if we're looking at the same sky Annie," or something like that
Danny
Danny's got energy enough for three people but it's her natural curiosity of the world that I find endearing, I thought something that gave off a carefree feeling yet might still touch on her interest in the outside world would be enough, I also looked for something that might show the innocence she has but also her consideration for others.
Ray
This is one of the one's that took time and I'm still on the fence but Ray has a subtle maturity about him but also this easygoing nature that makes him approachable kind of a good balance, I wanted one that wasn't excitable and had a bit of mystery too it as it seems he has some things in his past that may have made him the person he is today. Figured something with a smoothness to it would work
Alicia
Don't know that much about Alicia but what little I saw had me a little curios. When I thought about that I wondered what about one that touches on the mystique about her that leads to wanting to learn more but also the desire not to get too close at the same time knowing the danger that might be lurking beneath.
I could think of one that fit perfectly so I chose this one
Prince
Don't know too much about you man so here's some Metal Gear, can't go wrong with it. Almost did the reanimator but felt that would be in incredibly bad taste (cause of you know Wesker) so here ya go
