Percy grinned as Dumblwdore glowered, glaring at the arm wrapped around Estelle. "The Kidemonas, and especially their leader, bring nothing but blood and death. Estelle, my girl, I beg you to come back to us. Don't let yourself be led down a path of darkness. " 
Percy smirked. "If I'm as evil as you say I am, then let God strike me down where I stand."  
Lightning struck, deafening the assembled crowd, leaving scorchmarks a few feet from where Percy and Estelle stood. 
Percy didn't hesitate. "Ha! Nice try, Jackass! Next time, give it your A-game!"

Percy, holding a megaphone, with a dozen guardians behind him: Whoever decided to hurt my little sister please come outside so I can peacefully break your legs

GUardians:  massive battle with that world's prorectors 
Percy: flashes in with a Shockwave that knocks everyone down
Percy: Enough! We came here to kick (insert baddie name here)'s ass, not everyone elses. 
Percy: God's. Keep it together. You should know better then to pick a fifht with everyone who disagrees with you. 
Travis: Percy, why are you covered in ink?
Annabeth: frowns were you at the aquarium fighting with Steve again. 
Percy: That squid is a dick and needs to go down

Percy: Stand down. I don't want to fight. 
Clarrisse: I do.

Annabeth: I have a plan. I need two matches, a paper clips, a dracena leg and a death.

Annabeth: Not yours. 
Percy: Closes mouth.
