Oh dear, I'm going to rant. I'm so sorry. A lot of what's about to come out of my fingers is headcanon. For that I apologize. Also I haven't played Xenogears in a few years now and a lot of the story is a bit of a blur to me...so forgive me if I make a million mistakes and make an ass of myself.
Dominia is so tough and yet so naive. I just...I don't even. Her greatest strength, which is her freakish willpower to get the job done, is also her greatest weakness because it makes her blind and it makes her stupid. ldkjfalsdk I fugging lurb that about her because I identify with that. You guys have no idea how much I want her to break someone's arm in an arm wrestling match.
It probably also doesn't help that Dominia doesn't canonically "end up" with Ramsus anyhow, and her feelings, at least to me, are unrequited. The one thing that's always kind of bothered me about a lot of female characters in fiction is that there always seems to be some sort of relationship/love interest drive in them, and a whole lot less on personal ambitions or familial pursuits. I really like the fact that Dominia isn't exactly 'chained' to wanting a million of Ramsus' babies and wants to get married to him forever and ever. To me she seems more...in love with his ideals, I guess? Just the way that she idolizes him looks more like the giddy reverence kids have for their heroes. At least to me. Derp. Basically she doesn't need to be married to Ramsus in order to be 'happy' in her life. In fact I'm pretty sure she'd be more happy if she became more like her 'idealized'/mentally constructed view of Ramsus, thus gaining his appreciation and his platonic affection. With that being said though I totally wouldn't mind if they just went at it...XD
Oh, she's also basically the last person of her race. Yeah. Manly.
