Annabeth's hitting a pentafecta on this; high achiever indeed. There's probably more. Like when Annabeth talks about leasing Percy or when Percy says he fears Annabeth and how she consistently tries to keep him on his toes and how bringing up Rachel on any other woman is an absolute no-no around Annabeth.
Battle of Labyrinth, Mark of Athena and House of Hades truly showcase the toxic traits of Annabeth.
Also, if you have read Chalice of the Gods or any other non canon fanfics Rick has published, you will clearly see the propaganda of putting Annabeth on a pedestal by undermining Percy is a legitimate thing.
And to all the skeptics, let's look at it logically. Please read solo Percy books and compare the characterization of Percy there with books in which Percy is with Annabeth, especially in later books. See how his character suffers.
The Sword of Hades, Son of Neptune, Son of Sobek, The Stolen Chariot, and so on.
Brb currently thinking how insane it would have been if Percy judo flipped Annabeth at the end of Titans curse like she did with him in MoA 💀 💃🏽
“Annabeth pulled away and studied his face. "Gods, I never thought-“
Percy grabbed her wrist and flipped her over his shoulder. She slammed into the stone pavement. The hunters cried out. Some surged forward, but Artemis shouted, "Hold! Stand down!'
Percy put his knee on annabeths chest. He pushed his forearm against her throat. he didn't care what the hunters or Artemis thought. A white-hot lump of anger expanded in his chest. A tumor of worry and bitterness that he been carrying around since the dance at Westover.
"If you ever leave me again," he said, his eyes stinging, "I swear to all the gods”.
