Been getting a bit back into Invincible stuff lately, especially what with Season 2 coming, and I remembered Nikki - the homeless girl whom Martian Man was friends with (and possibly living with?). And I still feel really bad about her honestly.
She's a pretty minor question but her role is both very tragic and also kinda raises several questions.
For one thing; why didn't Martian Man seemingly do anything for her? At least get her to social services or try to arrange some proper housing for her other than a condemned building. Is it due to lack of understanding of earth/humans due to being Martian? Or did he try but wasn't able to do anything?
There is probably an argument to be made that pulling strings for Nikki's sake would be too attention-drawing. People might notice this random homeless girl has some important connections and so keep an eye on her and might connect her to Martian Man.
She at least seemed to be still alive and getting food from the soup kitchen last she appeared. But still... given several other Guardians were shown with loved ones in the montage, it does give the implication that they were quite close, possibly even some kind of parental figure.
Given she's still homeless after his death and is never mentioned by others and also didn't appear to attend the funeral, it does give the impression as well that others are unaware of all. Although even if Martian Man did mention he was friends with a homeless kid; that's probably a fairly vague statement to go on and it'd probably be difficult tracking her down specifically.
But this means that while the families of the other guardians at least got to attend the funeral as a potential form of closure, and also could even possibly use one another for emotion support or appeal to the GDA for assistance... Nikki got none of those options or possibilities.
She's lost someone close to her and she doesn't appear to even have anyone to confide in or watch out for her; few would believe her if she tried discussing her feelings about Martian Man's death and even if they did it would only bring dangerous attention onto her.
Just a shitty situation all round for her and I kind of hope Season 2 shows she's continuing to at least do okay. Haven't read the comic (although I might) but from what I've seen it doesn't appear she was a comic character so I guess her fate's up to the show writers (assuming they choose to show her again anyway).
