Just to add to this (but with the underworld kids)
Nico and Hazel's eyes change color according to which gem is nearest to them, or whatever their normal eye color is if there isn't one near (Bright, bright gold for hazel, and dark but multicolored eyes for Nico like a gemstone). But both of them naturally have sweet eyes, that are kind, but learned their scary stares
On the other hand, Bianca has the deepest darkest eyes (that don't change color) , this changed slightly after she became a hunter, but she and Nico both have intimidating stares (Bianca was born with it, but Nico learned it from her), while Hazel has a stunning wolf stare.
Nico di Angelo with the biggest doe eyes. Big, wide, adoring brown eyes. People can't help but fall in love when they see those eyes.
Will Solace with the most feline eyes. Pretty, upturned, cynically curious, blue eyes. People can't help but be uncomfortable when they see those eyes.
Nico di Angelo who had been stereotyped as unsettling and strange (he can be BUT) he has been looking out for and helping people nearly all his life.
Will Solace who has been stereotyped as unthinkingly optimistic and trusting (he can be BUT) he is curious, chooses his battles, and helps people through tough love and unconventional guidence.
I love music!
Alright I got that Nico/Eros playlist made (mostly. I’m probably gonna find more songs later and add them) so here it is. Some songs are about Eros point of view and some songs are about Nico going through it.
If you know any more songs for them please let me know and I’ll add it) (I wish Apple Music would let us share playlists like Spotify smh)
(Also if you can’t tell the whole album by Christian Death is about Eros following Nico since he was a young child and thinking back to his childhood a lot and how he kinda noticed the sings that some entity was following and he was terrified of the thing but he didn’t want anyone to think he’s crazy so he never told anyone and suffered Eros’s abuse all alone.)
(Some of the songs are about Nicos hatred for Eros or about him recovering or about Eros following Nico well into his adult years and Nico trying to cope or even breaking giving up and playing along with Eros)
Nico found out that the dead don’t get to eat or taste or see anything so he summons them just so that their afterlife isn’t so sad/lonely/stagnant
Nico jumping around the world visiting random people, and he keeps bumping into the hunters, and they're all awkwardly staring at each other before he makes an awkward excuse to go away
Nico just knows everyone in different pantheons, and is on good terms with them
Nico is a baby gremlin, and adorable, and the only place where he isn't accepted is camp half-blood, and camp jupiter
ooh, this is so cool
I know it's unfair vilification and stuff but it's also a lot of fun to see old media and stuff where people were SO scared of big animals like lions, sharks, crocodiles and wolves were fully expected to just come and eat you the moment you stepped into their territory. In older media we also made that assumption about gorillas and in still older we thought it'd be whales. But some animals that will actually fuck you up got left behind. Boars will kill you and eat you. They're way more likely to do so than any of those other things actually. Hippos, obviously, got off like bandits always being depicted as cute and dopey. And then there's the squids. Not giant kraken size squids. The eight foot squids that hunt in packs and will fuck you up if you fall in the water at night. I can't BELIEVE people slept on that. It's like all they cared about were the huge deep sea ones we never see. The medium size wolf pack squids were right there.
Aww!!!
Cat distribution system
The hypnos' cabin is actually really powerful, but like mentally, they can send you to sleep instantly, when using the Lethe water in their cabin, they can give you nightmares, communicate in dreams, and stuff
They have their own dream realm
i'll add more later
Nico found out that the dead don’t get to eat or taste or see anything so he summons them just so that they’re afterlife isn’t so sad/lonely/stagnant
now bear with me here, what if that's why Nico is so powerful, like at 12 yrs old he was more powerful that Bianca ( I know we don't have proof but still)
There’s something to be said about Nico and Bianca being so close in age and Bianca feeling like she had to raise him rather than just be his sister. Nico doesn’t see it that way he doesn’t want Bianca to be his mom he just wants her to be a sister and a friend and ally. Nico sees it as the tow of them equally looking out for each other equally. You see how protective he is when Thorn disrespects her and Nico almost told him to go shove the great army up his butt. 1930s Italy patriarchy Italy raised Bianca to take care of everybody in her family and not expect to be taken care of and looked after in return. Nico always knew that was bullshit. Maria raised them both to look after each other equally. Maria raised Nico to be aware that people (men) won’t take Bianca seriously and that he needs to be there to stand up for her. Nico is all but willing to throw hands for her. He tried to go on the quest with them. He tried to sneak off after the hunters to protect her but Percy stopped him because he’s “too young”. And that’s the only reason he made Percy promise to protect her if he wouldn’t allow Nico to do it. Hes only one year younger than her. Maybe a year and a half but that’s not much of a difference. I can’t imagine how angry Nico was at the world cause they didn’t let him go on the quest specifically to protect Bianca and she ended up dying. How Nico must have blamed himself just as much as Percy. Blames himself for not finding a way to follow them for not finding a way to protect her like he was raised to do. That’s a big part of the reason why he was so attached to her. They were each others protectors.
(Sorry if I’m rambling here I’m a bit sleep deprived and not sure if my points are getting across)
(And this last part is just my little head cannon you don’t have to believe this part if you don’t want to but this is what I believe)
I think when Bianca was born a girl Maria was very worried for her because of the environment and time period they lived in. So Maria straight up asked Hades to make a boy to protect her just in case Bianca standing up for herself is not enough. Just in case. Because humans in numbers working together are so much stronger than humans working alone. Maria didn’t ever want her baby girl to feel alone in the fucked up world they lived in. And she knew it wouldn’t be the same to be there as a mother because she’s mortal and Bianca is demigod and needs someone to relate to and was worried Bianca could never relate to anyone or anything and feel alone even if her mom is right there. So Maria asked Hades for a boy. And that’s Nico’s whole purpose in life is just to be there for Bianca. That’s why he’s so attached. And that’s why he’s doesn’t know what to do where to go and doesn’t even know who he even is after she died. Because that was his whole life. That was his whole reason for living. For existing. Now it’s all gone. If there was only a Nico because there was a Bianca first, then if Bianca ceases to exist then, does Nico cease to exist too?
They both look extremely similar, in fact, if you give them the same hairstyle, they would practically look the same, the difference is that Nico is usually terrifying to be near or look at, but Bianca is nicer ( funnily enough Bianca is more introverted while Nico is an extrovert). But if you look Nico in the eyes and suddenly you both are best friends (you just can't resist the soulful eyes) and also they're colored like earth (brown but with highlights of Gold Green, and Purple mainly but a bunch of other colors, and really, really pretty. Also they change color depending on the closest and biggest Jewel/Mineral nearby). While Bianca's eyes suck in all the light and are dark pitch black, and she gives terrifying death glares. But when blindfolded or something looks extremely nice
Nico's nickname is niccolo piccolo,
