since the janny is being a more of a bitch than usual today i will bring my humble theory here
i believe that kris is/ was supposed to be the second hero
all the requirements we see and are told for it are met by kris:
uses swords, wears ribbons, LOVE/ love has found its way to them by way of (you) and susie, love can be either platonic or romantic
while susie takes 'hope crossed on her heart' as written on, crossed can also mean crossed out, which i believe is the case for kris based on behaviour and what little backstory we have for kris
this leaves the final, and most important, requirement: being a girl
lots of people seem to believe that kris is non binary, but this is never stated in any official material nor by toby, it's purely a fan thing
kris going by they/ them could be for a multitude of reasons, but based on behaviour i highly doubt kris went around telling everyone his pronouns, doesn't seem like her style
one piece of evidence for female kris is the princess ribbon, in which all the equip text states that they cannot wear the gloves (susie and ralsei), but interestingly enough noelle says that kris can, this means that kris must have dainty little princess hands to wear the delicate gloves
i guess kris rejecting the ice-e body wash could count as one as it's specifically for boys and kris uses apple shampoo, but that's iffy at best, same with the inspect text on kris' dark world wardrobe, it seems to imply that kris is unable to wear what she would want to, and only has asriel's old clothing to wear
i think kris being female also adds on to kris' identity issues, as having things like a period would be even more alien her family than male puberty that would likely be similar to asriel's and make kris feel like even more of a freak than he already would being the sole human in a monster town

that's the appeal for male kris though
people fucking the characters vicariously through kris
with female kris it adds to kris' identity issues, forced to wear boy's clothing, living in the shadow of her perfect brother even if she does love him, her biggest role models were her brother and his tomboy girlfriend, with no real feminine influences, and her best friend is also similarly more masculine than feminine, at least for the most part
the only trustworthy feminine figure in kris' life would be noelle, and due to reasons she disconnected with her, likely due to dess' disappearance
it also adds another layer into the 'ralsei is kris' monstersona' idea, that kris thought his family would be happier if she were another monster son instead of a human daughter
