my first thought for six was brain which makes sense. it’s stated in all sorts of official media that she’s insanely clever, especially for her age might i add.
she navigates the entirety of the maw on her own, facing brutal monsters that want her dead, solving puzzles and doing a whole ton of dirty work. she’s clearly adapted to this world as well, and doesn’t break easily.
shes strong too. physically and mentally. theres an astounding amount of things she has to go through, keeping in mind that this world was not made for her in mind at all. everything around her is huge, and on top of that shes basically considered vermin. but she surpasses everyones expectations with her skills, and escapes the maw alive; harmed certainly, but alive.
and i was going to start this with heart is what she’s lacking, but that’s worded horribly and just .. wrong. she has tons of heart, she just doesnt really. like it. and so she deals with it differently; she pushes it down.
that’s not always easy though. sometimes she lets her guard down. in vln, she helps out rcg, even if that ends horribly, her heart was in the right place. throughout the first game, she hugs nomes, and provides them a source of light and warmth. and in ln2, she becomes attached to mono possibly more than she’s ever been to anyone else. even if it wasn’t her intent, she definitely grows to care for him atleast a little; but survive is still her top priority, and always will be (as it should be tbh).
we see this at the beginning when they meet; the moment mono provides an exit and shows he isn’t a threat, six bolts, and only allows him nearby when she realises he can help her. this situation ends in defeat because before she knows it, they’ve been through all of it together, and they’re friends.
.. but still she pushes it down. because getting attached could be dangerous. she’s independent, strong and clever, and anyone who can’t match her wit is weak to her, and could slow her down. and even if she’s right, what she doesn’t know is that it will hurt anyways. she tries so hard not to get attached but it doesn’t always work, and pretending those feelings aren’t there only ends up hurting more than she thinks, and it will keep hurting again and again and again.
as for mono, i thought he’d fit in brawn. he’s definitely the strongest of them (not to say the others aren’t strong of course), again both mentally and physically.
he’s born naturally with a decent amount of strength, and like i believe i said before, you have to be strong to survive this world for long, or yknow, at all. he’s good at facing danger upfront, using tools to his advantage.
mentally, he definitely worries a lot, but he also does his best to stay on the positive side of things and look for the silver lining, and help others lean towards that track too; even if they dont want it, cough cough.
that’s where heart comes in. he’s got a lot of that, and isn’t very afraid to show it. having someone to protect gives him a purpose, and a feeling of fulfillment; again, even if that someone doesnt want/need it.
his big heart helps him gain allies, friends even, but his need to protect can get in the way of his own survival as well. even if he’s doing the right thing, that doesn’t mean it’s not dangerous.
counterpoint, like i said, having someone to protect gives him purpose; it gives him a reason to stay alive and really do his best. it’s a huge motivation for him, which is why he can easily get attached to others.
as for brain, he’s also insanely clever, and is especially crafty with tools, in a similar way six is crafty with her environment, which is one of the many reasons they make a great team.
onto rk!
the reason i ended up with brain for six and brawn for mono is actually because i immediately thought of rk as heart; and he is. he’s kind, and very willing to help out, but he isn’t a doormat either. he’s emotionally clever and very in-tune with his own thoughts, and has a great amount of determination (hence his name/title, duh). he’s willing to give everyone a chance but knows boundaries and limitations too; there’s no manipulating or tricking him.
he can tell when he’s gone too far, or when others have, and can befriend almost anyone; although that doesn’t mean he will. if someone is rude, or just doesn’t want anything to do with him, he’s aware of that and will likely return the feeling. he won’t really push (mono on the other hand definitely will, which can be both a positive and negative trait).
he definitely isn’t the strongest, but again, say it with me, you have to be strong to survive in this world, mentally and physically. no amount of just heart or brains can get you out alive, even if it gets you far. although it’s not like there’s an escape at all, i suppose. while the ln world wasn’t always the way it is, it really does seem like there’s no turning back. this world is twisted and that’s just how it is now, sometimes not even strength, or all 3 traits i’ve mentioned, can get you “out” alive. rk knows firsthand.
