Hi Peyton!! ❤️🧡🖤 for the ask game?
Thank you, Hero, and hi!! I answered ❤️ and 🧡 here, but I'll answer ❤️ again, since I always have headcanons to share!
❤️ - Do you have any headcanons about your F/O? Are they common or not? What inspired them?
I'm the only one to my knowledge who's ever put all that much thought into Madeline's backstory, so her origin as a robot combat prodigy from Earth who met my self-insert online is something I came up with on my own! My lore for that time period is inspired both by canon (like her childhood nickname being Delly, which I explained here) and by a blend of actual friendships and experiences I had at around the age I first got into the Metroid series. (A lot of the inside jokes her and my self-insert share from their youth reference early-2010s internet and gaming culture and memes for that reason.)
I gotta admit, I've also got some headcanons that I've ported from other characters I loved since they seemed like they suited Madeline, too. Since I consider her kind of my "ultimate" F/O, in the sense that in hindsight I feel like I gravitated towards a lot of my past F/Os because of similarities to her, I've taken some tidbits about them and used them to flesh her out in little ways far beyond the scope of the canon narrative:
Her taking up gardening? In addition to working on the thematic level I described in my last post, that was originally a Laurel thing.
She orders her coffee black and her tea strong, just like Kathryn.
Her go-to dessert may be donuts or mochi, but she's nostalgic for rocky road ice cream, like Poppy.
…And she shares Poppy's lifelong trust of robots over people, as reliable beings with functions and roles that make more sense than the human hierarchies she hides her troubles with fitting into and enforcing. (Which makes what ends up happening on the Bottle Ship very ironic.)
And I'm sure I'll think of more!
🖤 - If your F/O has any friends / colleagues / family, how do you feel about them? Would you get along? What's your relationship with them like?
Well, kind of Melissa, but the extent to which Madeline considers her family pre-canon—and whether Melissa would still see Madeline as family if she survives into post-canon—is a whole can of worms that even I'm not 100% sure about at this point. (In fairness, I don't think they would be, either.)
My self-insert would definitely be the one person who sees her more as a human than anyone else on the Bottle Ship, to an extent that even Melissa isn't sure what to make of. I still think this one bit from one of my Selfshiptober fics from last year sums it up pretty well:
Peyton waved to her with a smile. “Hi, Melissa!”
Melissa stared for another moment, then lifted a rigid hand to wave back, the slightest smile gracing her face. “Hello.”
And then there's the four colleagues that Madeline was surrounded by in flashbacks. I have some ideas for how I'm going to flesh out their characters and how they each would've interacted with my self-insert, but I'll save that for the fic I plan on writing. (Of course, we all know how that's going to end for them…)
Lastly, this doesn't have the same kind of basis in canon as a lot of my other headcanons, but here's one I've been considering that I haven't told anyone about yet:
This unnamed dweeb right here?
Madeline's younger brother.
I mean, they don't look completely the same or anything, but they definitely look like it could be possible, right?
On one hand, the fact that he was the Head Quarantine Officer would imply that his earning that position wasn't a favor the way that my self-insert's role as Madeline's assistant was. On the other, he was so nervous and awkward around Samus that he nearly gave everything away right then and there, and she remembered him specifically when she realized cell samples had been taken from her suit without her knowledge. So, in my canon, his deal could be that she was the one who contacted him and got him involved with getting those samples.
My self-insert would've known him from when they were all teenagers, maybe tagged along to Madeline's robot combat events as a group sometimes. But they wouldn't have been close or anything, and lost contact at the same time that I originally drifted apart from Madeline.
…And I've been thinking there's potential for him to act as a foil for Madeline post-canon. He had enough distance from the consequences of the Bottle Ship Incident to not learn his lesson the way Madeline did, so he could end up just getting further and further wrapped in the continued unethical experiments we see glimpses of in Fusion. After all, we know that not everyone involved was brought to justice. (I mean, he wouldn't have been on the B.S.L. Station itself, because then he'd be dead, but still.)
That'd make my self-insert not get along with him at all, because what the hell, dude, but it'd make for interesting character interactions for sure! (And awkward family gatherings.)
