What is a battle cry from Percy Jackson in The Lightning Thief?

While Percy Jackson doesn't have a specific battle cry in *The Lightning Thief*, he does use a powerful and impactful phrase in the midst of the action:

"For Olympus!"

This phrase encapsulates his dedication to his Olympian heritage and his willingness to fight for his god, Poseidon, and the fate of Mount Olympus itself. It's a rallying cry that reflects his courage and unwavering loyalty.
