He wants to do better (career-wise) than his father, so Percy willingly turns his back on Professor Dumbledore and joins with Fudge and Professor Umbridge.
Percy proved himself to be very much of a social climber. He wanted to achieve prominence at the Ministry, choosing to dedicate himself to the institution and abandoning his family when they chose to rebel against the Ministry.
Percy was shown to be particularly disrespectful towards Mr. Weasley, going so far as to call his own father an idiot right to his face while the whole family watched. He didn't even have the courtesy to visit his father after he was nearly fatally attacked by a giant serpent, instead of returning Mrs.
But, as Voldemort started to take power, Percy ended up siding with his beloved Ministry over his own family. Percy wasn't a bad person and didn't have any desire to join the Dark Side, he was just easily impressed by power and status.
On the train ride back to London, Harry curiously asks Ginny what she caught Percy doing. She giggles and replies that he was kissing his girlfriend, Penelope Clearwater, in an empty classroom.
The Entire Life of Percy Weasley (Harry Potter Explained)
Is Percy Weasley autistic?
Percy is an introvert, in a very extroverted family. He is very rule-oriented, mature in many ways and naïve in others, a bit socially awkward, and tends to hyper-focus. These are fairly classing signs of Autism, particularly in males.
Upon returning to Camp Half Blood, Percy is betrayed by his friend Luke, son of Hermes, who turns out to be the human hero whom Kronos used for the theft. Luke poisons Percy, and tells him before leaving that Kronos will rise and destroy the age of the gods. Western Civilization is unraveling.
Percy never became bad, but he did become a self centered, power hungry bigot. His love for the ministry and his obsession with his future caused him to become oblivious to the rest of his family. He spent too much time working to even notice his family's concerns for him.
Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom. Due to Neville's death, the final Horcrux Nagini was never destroyed, and as a result Voldemort is never defeated, kills Harry and takes over the Wizarding World.
Percy thinks that Fudge is the way for him to establish a real career for himself. He wants to do better (career-wise) than his father, so Percy willingly turns his back on Professor Dumbledore and joins with Fudge and Professor Umbridge.
In a tense moment, Percy apologized profusely to his family, and his brother Fred was the first to forgive him. His mother burst into tears and rushed forward to embrace him, followed by his father, whom he had fallen out with the worst.
The only member of the Weasley family to truly represent anything actually deep-down bad was Percy Weasley. Despite being surrounded by quite a cool family, he ended up being a pompous, arrogant snob who wanted nothing more than the utmost respect and power.
You are sorted into a house based on what you value, not the traits you posses. Percy valued the Gryffindor traits and therefore was sorted into Gryffindor.
In the first four books he wasn't liked simply because he wasn't viewed as a 'fun' character. The twins didn't like him thus meaning Ron, who wanted the twins to like him, didn't either and that feeds into Harry's own view of Percy.
Afraid that her mother's job was in jeopardy, and not convinced by Harry's interview in The Quibbler, she revealed the location of the D.A.'s meetings to Umbridge.
Their relationship grew stronger after the death of Cedric Diggory, but Harry suspected Cho of betraying their secret student group. Cho's lingering feelings for Cedric and a lack of chemistry between her and Harry contributed to their breakup, leading to Harry ultimately ending up with Ginny Weasley.
Alice and Frank Longbottom were not killed. They were tortured with the Cruciatus Curse to the point of insanity. It was a combination of Bellatrix Lestrange, Rodolphus Lestrange, Rabastan Lestrange, and Barty Crouch Jr.
Voldemort ordered Pettigrew to "Kill the spare," and he used Voldemort's own wand to kill Cedric with the Killing Curse. Although dead, Cedric still had a role to play in the night's events.
The Weasleys are known for not supporting the notion of blood purity. They were considered one the biggest "blood traitor" families within the wizarding world of Great Britain. They willingly associated with Muggles, Muggle-borns, and other "blood traitors".
She survived the war and eventually married a muggle Mr. Campbell and had a daughter named Erin. Even though Cho seemed very innocent and kind, she still couldn't get over the fact that Cedric Diggory was dead and Harry Potter, her new crush, had been right beside Cedric when he died.
It is only at the end that it is revealed that Penelope is Percy's girlfriend; this explains the magnitude of the shock Percy feels when she is petrified, as well as explaining what she was doing in the school's lower levels at Christmas, near where Percy was.
Percy pulled Annabeth close and kissed her... long enough for it to get really awkward for Piper, though she said nothing. She thought about the old rule of Aphrodite's cabin: that to be recognized as a daughter of the love goddess, you had to break someone's heart.
When Grover goes before the Council and tells them of Pan's death, the satyrs brand him a traitor and demand his exile, but Chiron and Dionysus believe and support him. Because Dionysus' vote counts for two, the Council is unable to reach a decision and must be dissolved, allowing Grover to remain.
An altercation with Clarisse allows Percy to discover his father is Poseidon, one of the “Big Three” gods. This revelation is cut short when a hellhound attacks Percy from the Fields of Punishment.
