In "The Red Pyramid," a character named Amos shouts a peculiar battle cry, "For Brooklyn!"

Instead, this phrase evokes a sense of community and local pride, reflecting the characters' connection to their hometown during a critical moment in the story.

The use of such an unexpected battle cry highlights the blend of everyday references within a fantastical narrative, showcasing Rick Riordan's unique storytelling style. It serves to ground the characters in their reality while also emphasizing their determination to fight for what they care about, making the scene both relatable and engaging for readers.
