Percy Jackson vs Harry Potter

Panic

Hermione's P.O.V
"But how will you fight without a leader?" The hooded figure asked before fading out of view. I had a few seconds to make eye contact with the other girl before my world went black.

I woke up to Ron in my face screaming. "It's Harry! He's gone!"
-"What do you mean he's gone?!"
-"I said goodnight to him and in the morning he wasn't there?!"
-"Maybe he just left to take a walk or something!" Shouted one of my dorm roommates
-"I told the teachers they used a spell to search the school, and there is still no trace of him!" Shouted back Ron

"IT WAS THE FIGURE!"

Everyone looked at me. "The thing that happened to Harry, it happened to me too! I faced some girl with gray eyes who used some sort of bronze knife. And there was a figure, who put us against each other! Before I came back here, he asked me how we could beat him without our leaders! He must've taken Harry! It had to have been him!"

Ron stood up. "Come on, quick, let's tell the teachers what happened, the you can explain it in detail. We need to find Harry"

Annabeth's P.O.V
"But how will you fight without a leader?" The hooded figure asked before fading out of view. I had a few seconds to make eye contact with the other girl before my world went black.

I groggily opened my eyes, and sat up straight, and took in my surroundings. All of sudden, the memories of what happened flooded my brain. Eyes wide, I jumped to my feet and started sprinting to camp, only to find it in chaos. The conch horn was blown 3 times, signalling a monster attack.
I sprinted to the top of Half-Blood Hill, and eyes wide, swept my eyes over the vast amount of monsters not to far from the border. It looked like they were chasing something... No, someone... Nico! It didn't look to well for him, he was fighting a losing battle against a seemingly infinite amount of monsters. Without wasting any time, I screamed for reinforcements before sprinting down the hill to rescue Nico. Where was Percy?

A group of dracaena spotted me and tried to intercept me. I quickly cut them down with my drakon bone sword. I kept running. I quickly stabbed an lastrygonian before spinning around and parrying a strike from an empousa. A few cyclops charged at me, I dived threw their legs leaving them to fight amongst themselves to find me. Almost there, the son of Hades finally spotted me, and tried to make his way towards me but was then preoccupied by the Minotaur bringing down his axe. I turned a hellhound to dust, stabbed a cyclops, ducked under a empousa strike, and plowed through a hooded guy with a sword and a stick. Wait. A sword and a stick?

I turned around,many sure enough, there was a guy charging at me, holding a celestial bronze sword while shooting spells out of a stick. Wait a second... That sword looks familiar...

I didn't have to dwell on it though because soon enough the guy was onto me swinging his sword with such power I was only barely redirecting his blows. I got over my shock of seeing the wand and started my counter attack. The next time we clashed blades, I used my sword to push his sword away, then attempted to stab him with my dagger. He ducked under my strike, and then jumped away to get some distance. He then shot a few spells at me which I easily dodged. He charged me again. This fighting style seems familiar, very familiar...

This time, when we locked blades, I pushed with all the strength I could muster to keep up with his strength. All of a sudden, he let go of his sword and sidestepped, causing me to fly forward. He then swept my legs out from under me causing me to fall to the dirt. He picked up his sword again. Is this the end?
Out of the corner of my eye, I could see Nico on one side, desperately trying to get to me, and the campers in the other charging into battle. The hooded figure lifted his sword above his head, hesitated once, twice, and then brought it down full force.

Wait a second. I know that sword, how could I not have recognized it sooner?!

It's riptide.

I glanced under the figure's hood. I saw a pair of sea green eyes that could only belong to one person.

The sword hit me and my world went black.
