Author's note: My first crossover on this site! This is of two of my major obsessions, Big Hero 6 and the Percy Jackson series. I hope to have characters from both, but you never know! Anyways, enjoy!

Gogo's POV

Gogo Tomago was having the most confusing day of her entire life.

Everything had started out decently enough. As days go, this one wasn't the best- the tech she was working on blew up, and she got into three fights in the space of four hours, but that wasn't anything exceptionally weird. As a matter of fact, Gogo got into plenty of fights. Only newer types at that school picked fights with her. Despite her small size, she invariably tended to leave her opponent with at least one broken bone. The blowing the tech up thing was a little different, but mistakes happened.

The entire weirdness part came later that day when she and her two best friends- the Hamada brothers Hiro and Tadashi- almost died.

Tadashi was driving all three of them some place, to do- well... whatever it is that friends do when the car hit something. It jerked to the side, causing Hiro and she to yelp, and Tadashi to say something in Japanese. Gogo might not have known any Japanese, but she was willing to be he was swearing.

"What was that?!" Hiro asked. Gogo glanced back at him, feeling a surge of concern for him. He had a bloody nose, but otherwise seemed alright.

"I don't-"

Tadashi cut Gogo's answer off, with another Japanese word that was probably another swear.

"Get out, both of you! Now!"

Gogo and Hiro didn't argue. They both scrambled from the car. A minute later, Tadashi joined them.

Now, let's get one thing straight. Gogo was not what you would call a coward. In fact, she was generally the opposite. She had a kind of stubborn bravery and toughness that some people- as in her close friends- called recklessness. In the entire history of the school year, there wasn't a single dare that she had refused. But now, for once, Gogo was terrified.

It's easy to be unafraid of things that make sense. But now she, Tadashi, and Hiro, were facing a huge bronze bull. Its ruby-red eyes locked straight on her, and it charged.

"RIGHT!" Tadashi shouted to her, pulling Hiro out of harm's way.

Gogo had no idea what that meant, but she let her instincts take over, diving to the right, as the thing thundered past her. She stood, relieved that she had fast reflexes. There was no time to celebrate though, the bull was coming around again, ignoring everybody but her. She got ready to dodge a second time, and once again, jumped away.

A little too slow.

The razor sharp horns missed her face by inches, but she fell, just in time to feel something snap in her right leg. She tried to move, but almost blacked out.

Broken.

More thundering.

Then there was someone else in front of her.

The blonde girl had literally come out of nowhere, striking at the bronze bull. It turned away from its intended target, and attacked the girl instead.

Gogo's brain, unable to keep up with what was going on, decided to do the easy thing, and make her pass out.

Tadashi's POV

Tadashi was also confused out of his mind. All he could do was watch in shock as the blonde girl killed the bronze bull thing. As soon as she was done, she ran over to him and Hiro.

"Are you two alright?" she asked.

"Fine," Hiro and Tadashi said in unison.

"Good." She turned away from them, running to Gogo's side.

Tadashi felt a flash of concern, followed by guilt. He had been too busy watching the blonde girl fight to realize that Gogo had been hurt.

Some friend you are.

He waited nervously while the blond girl checked her over.

Eventually, she stood.

"Could have been worse."

"Shouldn't we take her to a hospital?" Hiro asked.

"No. Too dangerous. The three of you need to come with me."

"What makes you think we would do that?" Tadashi was the first to speak.

"You don't really have a choice," the girl replied. "It's not safe. Now help me with her."

Tadashi, numbly, walked over, lifting up a totally limp Gogo.

"Let's go," the girl jerked her head, and Tadashi and Hiro followed her.

Tadashi was desperately hoping that Gogo stayed unconscious for a little longer, because she would kill him otherwise.

The girl stopped by a car.

"Get it."

"Whoa you can't just expect us to-" Hiro started.

"It'll be safer if you come with me," the girl insisted.

"Who are you even?" Tadashi demanded.

"My name's Annabeth Chase," the girl replied. "Now come on. It's going to be a bit of a ride."

"Where are we going?" Tadashi finally asked. He had to admit that he didn't know what else to do. As gently as possible, he put Gogo in the back. Hiro sat next to her, and Tadashi took the front.

"Camp. You might as well sleep," Annabeth replied. "You'll probably need it."
