Some of you probably know I'm not too big on shipping unless it's just played for laughs or fun. Being too serious about it just takes the fun out it for me.
So while I've yet to think of any real ships I've really come to like, I am somewhat lenient on the idea behind BassXRoll, but only if it's just a crush on her end and nothing going further beyond that. Yeah, I'm thinking of that one scene from the Battle and Chase manga below.

I'm initially opposed to it being a full-blown romance because it really exemplifies the cliché, 'good girl falling for bad boy' which I've seen very rarely work in other media, and further make Bass more of the Vegata-expy than he already is and make Roll his equivalent to Bulma (minus the part where they have a kid since they are still robots). Plus, I'm not sure if I'd really like Roll that much if she did really did fall in love with the guy who wants her brother, whom she's very close to, dead.
So yeah, while I'm not totally behind that ship, I wouldn't mind if was treated as a little one-sided crush for a pre-teen girl like Roll to have, and Bass would hardly notice or care. And even if he did notice he'd probably just use as an advantage over Mega Man. Could he still show some sensitivity to her if she got upset or something? Sure, I'd be fine with it and would even like to see Bass show some semblance of good in him (preferably sometimes with Treble and few and between with anyone else), but any niceness he shows her will just encourage her crush on him.
