Percy Jackson vs Harry Potter

Beginning the battle

Percy's P.O.V
Just who does this guy think he is?! Whatever, I'll show him! I launched some water at him as I ducked under a spell. "WHAT TH-" he screamed before he was completely emerged in water. Huh, guess he hasn't heard about my abilities then. Easier for me! All of a sudden I heard "Expelliarmus!" And then a beam of light came out from the water and I was forced to think fast and deflect it with my sword. All of a sudden, Riptide was ripped (no pun intended) from my grasp and flew across the room.

Harry's P.O.V
Now's my chance! I thought as I bolted across the room shouting stupefy over and over again. He must have been trained well because he dodged every one of them. He then screamed and he was immediately surrounded in a hurricane. He charged at me and I had no choice but to reveal my ace. "Accio broom!" I screamed and I took off on my broom just in time to avoid the hurricane. I then started attacking him with a barrage of spells. He dodged them with ease but the. On the last stupefy he dodged but he slipped and fell to the ground. I quickly jumped on the chance and shot another stupefy at him.

Percy's P.O.V
The red beam of light came to me in slow motion. When it hits me, I wonder, will I disintegrate, or will I turn into a grease spot, or ok that's my ADHD acting up again. I'll use my new technique that I developed, cmon Percy, concentrate...

Harry's P.O.V
I smirked as the stupefy hit him. That'll teach him not to mess with the boy who lived! But then my jaw dropped as he turned into water!I looked behind me and saw him with his sword raised. I reacted just in time and dodged to the left. I saw my opportunity and before I could stop myself, I shouted "Avada Kedavra!", the killing curse.

Percy's P.O.V
I was suspended in mid air, I couldn't water teleport like last time, it took too much energy out of me. All of a sudden I heard: "PERCY!!!" and as I landed, I turned around and choked. I saw the form of Clarisse falling from the sky. I quickly rushed to her and said "Cmon Clarisse, stay with me, cmon!" She raised her arm and grabbed mine. "Listen here Prissy, you better *cough* win this fight, or... I'll never... *cough* forgive... y-you..." With that the legendary drakon slayer, daughter of the war God Ares, died.
