Flash and Arrow crossover

(Sample): I opened my eyes, waiting for the transformation to happen. Less than three seconds later, the change occurred. The transformation never ceased to amaze me and as I watched it, I remembered the times when the water was salty instead of clean, house water. Oh yeah, you still don't know who I am. Well, I'll give you a little summary. My name is Aquarina, Aqua for short. I just moved to Dallas, Texas from a little town called Fort Myers in Florida. I will be a junior in high school this year. Oh and let's just say I'm not your average 17 year old girl. I mean I dress like a normal girl, minus the face cake of makeup and the heels.(Yeah, sorry. I don't do high heels. I only go for 1-inch heels if anything.) I listen to normal music and I talk like everyone else. Normal American accent. I also have a phone, computer, laptop, and all those other electronic necessities. I don't have any mental issues. I was born like any normal baby. Well, that's not entirely true. I am anything but normal or average. You see, my DNA is different. No, I'm not a werewolf. Or vampire, fairy, wizard, witch, or ghost. When my skin comes in contact with water, I change. My eyes and hair change. My eyes become a clear silver and my hair a solid blue, lighter than navy but darker than aqua, sorta like the Crayola color. I get a tail for feet and my scales are the color of my eyes. So now you think "Scales? Like a fish or something?" Actually that is half true. I'm half fish and half human. Yup, that's right. I'm a mermaid. That's not all of it. My family are as well. (End of Sample):

"You need to leave. Now." She said as she gave me her necklace along with a bag full of clothes with some food. Worry in her tone. "But where do I go?" I asked scared and confused about what was happening. "I don't know just run and remember never let anyone mistreat you and stay strong." She said ushering me out the door. "You have Alpha blood in you, use it to your advantage." She choked out through tears. "Mom please don't leave me!" I screamed through tears of my own. "It's going to be ok Sweetie just know that I love y-" she was cut off by a wolf ripping out her throat. I stood wide eyed but did as I was told and ran not looking back at the massacre behind me.
