Robin POV

It was a pretty normal day at the cave. Before the explosion.

Wally and Artemis were fighting, Kaldur was reading, Conner was watching static, Megan was making cookies, and I was playing around on my holo computer. Then we heard an explosion.

Luckily we were all in costume, but it didn't jar us any less.

"That all you got?!"shouted a male voice

"Don't invoke him Seaweed brain!"screamed an irritated female voice

I started running to the site of the explosion, the training room, and turned a corner to find two teenagers and a bull man.

"C'mon Tighty Whities try and hit me!"shouted the boy

The boy had bright blue eyes, jet black unruly hair, tan skin, and a 3 foot long bronze sword. He looked like some kind of rebel, like he would blow up a chemistry lab because he didn't listen to the instructions. But I figured he was dangerous and experienced by the way he held his sword and he was fit, lean, and muscular.

"I said shut up Percy!"shouted the girl

The girl had curly blonde hair, intense gray eyes, naturally tanned skin, and a bronze dagger. She was tall, fit, and athletic and looked as if she could take down anyone who talked to her while daydreaming.

"What the hell?!"shouted KF

The boy, Percy, turned in surprise to get tackled by the bull. The girl stabbed the bull and it transformed into gold dust.

"Good you're here."I turned to see Artemis walking over to the pair, smiling, and greet them.

"Wouldn't miss it Moon girl."grinned Percy, who high fived her. She pulled the girl in for a hug and turned to us.

"Say hello to my family."

I stared at Artemis, just a minute ago I thought she was a normal human. Now I knew she was different.

"Explain. Now."demanded Aqualad

Percy sighed, "You were right, I don't want to be here." he said to the girl before continuing, "Hello, I'm Percy Jackson and this is Annabeth Chase. We are demigod. The children of gods and humans. I'm the son of Poseidon and Wise Girl over here is daughter of Athena. Dad's the god of the sea her mom's the goddess of wisdom, battle strategy, art, and olives."

Annabeth sighed, "Shut up and let me explain. Anyway some of you are demigods, maybe one if not two of you definitely are, the rest, we have no idea. Some kids are recognized as demigods while they are asleep so they never know, but when you turn a certain age you should be eligible to find out your godly parent."

Wally frowned, "OK now that we know about you what about Artemis?"

The girl in question rolled her eyes and spoke up, "Since you're so eager to learn, Wally. Artemis, the goddess, trained me in archery and fighting, but my parent is Apollo. So in other words I was trained by my stepfather, aunt, and mother. I'm not really part of my mortal family at all. Well except for my mom. But anyway, we need to get you guys all to Camp Half-Blood to see who is really a demigod."

"I know for a fact I am not one of your kind. I will stay with Miss Martian and Superboy, who are undoubtedly not demigods."stated Kaldur

Artemis nodded and looked to KF and I, "Now we go to New York."
