Percy-How he actually is: Excessively loyal, calculating, quick-witted, sassy (at times), sarcastic, brave, reckless, smart, manipulative at times, and sometimes dark and ruthless.
How the fandom portrays him: Stupid, obsessed with Finding Nemo and The Little Mermaid, 'not your type' jokes to the point where it's annoying, 'Persassy'/always sassing someone, childish, dumb, and reckless.
Annabeth-
How she actually is: Smart, intelligent, quick-witted, fierce, analytical, judgmental, prideful, wise, possessive, easily jealous, rude at times, wise, audacious, and Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy.
How the fandom portrays her: sassy, funny, laid-back, tired, arrogant, vain (pride and vanity are different), rude at all times, mean, pushy, and strict.
Jason-
How he actually is: Noble, brave, a leader, sweet, humble, calm, patient, loyal, serious, funny at times, compassionate, honorable, just, kind, and modest.
How the fandom portrays him: Cold, rude, arrogant, humorous, laid-back, strict, merciless, unfriendly, mean, and honestly who knows the fandom changes his personality every three seconds.
Piper-
How she actually is: Aggressive, relaxed, selfish, rudely sarcastic, hypocritical, fake, obsessed, possessive, easily jealous, misogynistic, spoiled, manipulative, rude, short-tempered, arrogant, shallow, whiny, and Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason.
How the fandom portrays her: Fun, rebellious, iconic, laid-back, calm, hilarious, prankish, mischievous, funny, girly, humorously, sarcastic, sassy, chaotic, feministic, compassionate, understanding, and kind.
P.S: Piper is 'sarcastic' in a rude way intended to hurt whereas the fandom portrays her as the humorously sarcastic intended to be funny. And again- she didn't steal anything. She only got kicked out of the schools for being accused of stealing. She has literally never done anything remotely rebellious besides 'I cut my own hair!!111!' and the only time she ever canonically broke a rule, it wasn't even her choice. It was Jason's. And when did she ever care about others or talk to them about their problems again?
P.P.S: Annabeth has canonically broken rules. Piper hasn't.
Leo-
How he actually is: Funny, deep, laid-back, mischievous, insecure, angry, hurt, guilt-ridden, easygoing, very intelligent, energetic, upbeat, eccentric, flirty, brave, reckless, selfless, rude at times, emotional, sensitive, annoying, and quick-witted.
How the fandom portrays him: Flirty, funny, crazy, wired, jumpy, hyper, prankish, weird, annoying, and has no sense of emotions, depth, or insecurity whatsoever.
Frank-
How he actually is: Modest, sweet, insecure then confident, diligent, dutiful, brave, courageous, intelligent, cynical, soft, loyal, caring, sweet, courageous, selfless, and badass (he ripped a whole arrow out of his arm).
How the fandom portrays him: Innocent, pretty much blank, sensitive, either too emotional or completely emotionless, naïve, insecure, shy, fragile, and dramatic.
Hazel-
How she actually is: Confident, mature, compassionate, supportive, kind, guilt-ridden, creative, reliable, loyal, outgoing, caring, bright, comforting, reckless at times, and optimistic.
How the fandom portrays her: Always confused, naïve, innocent, simple, ignorant, sensitive, emotional, gullible, hates curse words, moral, virtuous, quiet, and introverted.
P.S: Besides Annabeth and the Stolls, Hazel is the only character who has canonically swore (multiple times). She literally had a tantrum and swore so much Leo was surprised. She does not hate curse words and is most definitely not 'innocent' (she was literally an accomplice to suicide and killed multiple monsters and a sorceress).
Reyna-
How she actually is: Strict, warm-hearted, thoughtful, brave, selfless, stubborn, independent, strong, stoic, dubious, unforgiving, intelligent, supportive, protective, confident, loyal, strong-willed, badass, and a leader.
How the fandom portrays her: Cold-hearted, unfriendly, shallow, rude, mean, emotionless, a romantic, jealous, dramatic, arrogant, merciless, cruel, and Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason Jason.
P.S: Everyone's giving shit to Reyna for being 'too strict'....honey, she's the Praetor. That's the equivalent of being the president. Everyone's hating her cause she 'told Lavinia to stop chewing gum so loud!!111!!!11!' but they were at a senate meeting. If- in the U.S- the president was talking to the Senate and a Senator was chewing gum so loudly the president could hear, you think the president would be mean for telling them to stop? Reyna has a formal and serious job...but people hate her cause she acts formal and serious??? Y'all make no damn sense.
P.P.S: Piper thought about Jason about 70% of the time in each of her chapters (I reread The Lost Hero. This is true). Reyna didn't even mention him. But Reyna is the Jason-obsessed one?
Nico-
How he actually is: Introverted, mysterious, lonely, sad, quiet, shy, naïve, unforgiving, independent, vengeful, insecure, unpredictable, strong-willed, resentful (or he holds grudges often), unreliable, and caring.
How the fandom portrays him: Creepy, vampire-like, grumpy, cruel, a desperate romantic who swoons and blushes over anything, a Percy fanboy, mean, and shallow OR cheerful, upbeat, happy, energetic, geeky, and obsessed with McDonalds (that was when he was a kid, not now), plus Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy, Will Will Will Will Will Will Will Will Will Will, and gay gay gay gay gay gay OR cute little adorable precious bean cinnamon roll.
P.S: Nico doesn't eat McDonalds. He uses the food from there to raise the dead. How did that translate into 'He LOVES eating there and loves all the cute little toys!!1111!!1!!'?
Rachel-
How she actually is: Calm, kind, charitable, selfless, brave, reckless, creative, intelligent, artsy, witty, open-minded, blunt, funny, laid-back, talkative, stubborn, helpful, quick-witted, humorous, and a volunteer.
How the fandom portrays her: Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy omg Annabeth is such a Percy Percy Percy Percy Percy Percy jealous Percy Percy Percy Percy Percy Percy Percy Percy Percy Percy.
