Disclaimer: I don't own percy Jackson or nanananananana BATMAN~! AND ALSO IMPORTANT! THIS TAKES PLACE BEFORE THE LOST HERO WHEN GROVER ACTUALLY WAS AROUND

"Seriously, whose idea was it to send the monster magnet to rescue an innocent kid." Annabeth grumbled.

"Shut up!" Percy replied. Gotham city had been nice in the day, Annabeth, Percy and Grover had even spent the day sightseeing-er-scouting. But now that it was dark...Strangely at exactly eight o'clock most of the stores locked and bolted their doors. Even most clubs and bars had closed by nine. And the houses, please! They were like Fort Knox version two. Grover nervously chattered his teeth which really got on Percy's nerves. "Grover will you stop doing that!" He finally snapped.

"So-sorry! It's just that I smell an incredible m-monster s-scent. It's like the d-drakon, hydra, ch-ch-chimera and medusa mixed with anti-ti-se-septic." He stuttered. Annabeth did her trademark eye roll.

"Oh come on Grover, it can't be that bad. We haven't run into a monster all day and that's saying a lot since we have the great lord of monster attracting sushi right here." Annabeth stated.

"Yeah...wait, HEY! Whose a sushi?" Percy argued finally catching on.

"Who else seaweed brain?" Annabeth smirked sarcastically. As they bickered Grover smelled the monster getting closer and closer.

"Uh, guy," he said tugging on Percy's coat.

"Just a sec Grover," he said busily think of a way to come up with a good comeback.

"Guys," Grover tried again tapping Annabeth on the shoulder. Annabeth promptly ignored him.

"Guys!"Grover shouted. "What?!" They both yelled back.

"Something is watching us!" He yelped in defense.

"Juvenile delinquents? Are you new in town?" Came a cocky voice from the shadows.

"Robin," warned a more mature voice. Just then Percy and Annabeth's battle instincts kicked in. Percy summoned riptide and Annabeth went into a battle stance.

"Grover are they monsters?" Percy asked. Grover sniffed the air.

"No, but one of them is a demigod and his scent is really strong" he replied. The group relaxed and put away their weapons. Percy awkwardly scratched the back of his head. "Uh, how do I say this...we come in peace?"

The strange kids put away their weapons. The kid with the black hair and sea green eyes somehow turned his sword into a pen. "Uh, how do I say this...we come in peace?" He said.

Robin turned and signaled batman.

"What should I do?" He signaled.

"Let's hear them out." Batman replied.

"So what are you doing in Gotham, if your from around here you'll know the dangers of Gotham at night," Robin stated.

"We're looking for a half blood," the green eyed kid replied. The blonde girl elbowed him.

"Great job, seaweed brain." She hissed sarcastically.

"Well Einstein if YOU have a better plan let's hear it," the kid argued back.

"Just watch me," she snapped. "Ahem, nice to meet you I'm Annabeth, that's Grover in the corner chewing on a can, and this idiot is Percy, but feel free to call him stupid, seaweed brain, kelp head, brat..."

"Just Percy will do " Percy interrupted. Robin wasn't sure if to step into the light or not but he could surely take them on if things got ugly. So he stepped into the light and said.

"Hi, I'm Robin, this is..."

"Batman! THE BATMAN!?" Grover gushed. "It's an honor to meet you sir," he said shaking batman's hand. Batman seemed mildly annoyed.

"Thank you, now can we get back to business." Batman stated flatly.

"Right, sir your right, we're from camp half blood..." Grover rambled.

The girl called Annabeth pushed him out of the way, "Ignore him, pleased to meet you, Mr. Wayne, Richard." She said extending a hand.
