Leo POV

After Natsu and Clarisse left we all gathered in the war room for whatever it is that Chiron had to tell us. Sitting around the ping pong table I noticed that Nico looked like he was trying to figure something out without even knowing what IT was. "Yo Nico what's wrong you look like you're having trouble with something?" I asked which got everybody's attention. They just looked at Nico waiting for an answer.

He scrunched his eyebrows even more before answering. "It's probably nothing, just a feeling I got off of Natsu. It was almost as if he wasn't …human." He said as if choosing his words very carefully.

"Dude we aren't even fully human I'm not even sure Percy is human at all." I said trying to lighten things up.

Resulting in a "hey!" from Percy.

"My point is it's probably nothing."

"You're probably right but we should keep an eye on him in case."

Then our group fell into silence for a few seconds before Chiron walked in. "Thank you all for coming" he said which is so unlike him. That's when we knew something had to be wrong.

"So why are we here? Is something wrong?"

"Oh no it is nothing like that but I would like all of you to keep an eye on Natsu for me."

"Yeah, we were just talking about that, and many things don't add up like why he was not been claimed yet if he is a demigod, and how he got here." Annabeth said with her thinking face on.

"he seems old to be a new camper," Percy said remembering he's deal with the gods that all their children would be claimed before the age of 15.

Just as Chiron was about to reply we all heard yelling and something about a fight I think. We all look at each other before getting up and running outside. We found a huge group of campers running to the canoe lake and when we got there we had to push our way to the front to see what was going on.

Standing across from each other both in battle poses were Clarisse and Natsu. And they both looked pretty mad.

Before we could stop the fight Clarisse charged Natsu spear ready to impale him, Natsu how ever did not move and he had a smirk on his face. When Clarisse got within sticking distance Natsu seemed to disappear and reappear behind Clarisse, Clarisse stopped mortally confused and turned around to see Natsu smiling at her.

"Why are you smiling you just ran away, what are you chicken to fight me." Clarisse said with her own smile

"No just thinking how much fun it will be when I kick your ass!" Natsu said as his smile grew bigger with Clarisse's growing anger. And she charged again and this time Natsu charged too with someone in the crowed saying Clarisse is going to kill him because he does not have a weapon to defend himself with. Natsu and Clarisse connected and in a blink of an eye Natsu grabbed the spear and punched Clarisse in the stomach sending her flying backwards. She landed on her back a little dazed, in fact everyone was shocked. Nobody was ever disarmed and beat Clarisse in one move before. Everyone was brought out of their trance when Natsu started laughing. Natsu was on his back still holding Clarisse's electric spear in one hand and the other was holding his stomach trying to stop the laughing fit he was having.

"Boy the look on your faces are hilarious!" Natsu said when he was finally done Laughing.

If looks could kill the one Clarisse was giving Natsu would have him six feet under already. She slowly stood up and in a man rage charged Natsu again only to be thrown back and knocked out by Natsu. My jaw dropped Natsu went from laughing hysterically to the most serious man I have ever seen. Is he bi-polar or something?

But now he is smiling again rubbing the back of his head sheepishly. "Ops sorry I didn't mean to do that guess I went a little over board." And now he is apologizing. Maybe he does this a lot.

Being the awesome person I am I was the only one who registered what he said. "Dude don't apologize that was awesome I don't think anyone has done that before." I walked up to him and clapped him on the back.

"Ok so where do I sleep exactly?" he asks. I guess they didn't get to finish their tour of the camp.

"I'll show you." I say as I start walking over to the cabins.

We walk in silence for a while but I can't take it anymore. "So what happened between you and Clarisse?"

"Well I got tired of her calling me a pinky and I tried to let it slide but that didn't go well when she called me a weakling and that is when I blew it and challenged her to a fight without using my magic, and that is when the hole camp started to watch and you showed up."

"Wait did you say magic!" I said a little shocked

"Yeah, what else would I mean?" Natsu said lighting his fist on fire and I was so happy and a little shocked

"You can use fire that is so awesome I did not think there was any one else that had the same powers as I do" doing the same thing with his fist. Natsu looked at that flames in my hand and a look of hunger appeared on his face.

"Hey Leo do you mind if I have a bite of your fire?"

"Uh what?"

Apparently taking that as a yes he just took my fire and ate it. He swallowed and smiled.

"That's really good fire."

"Uh Thanks I guess? How'd you eat my fire?"

"Oh well where I come from I'm the fire dragon slayer and so I eat fire to gain power."

"Oh that's cool. Wait did you just say dragon slayer?"

"Uh yeah."

"Dude that's awesome we are going to be best friends." He just smiled. And I noticed his fangs. Chiron will defiantly what to hear about where Natsu's form and his magic. I couldn't help but smile too.
