I woke up on my living room floor, in an uncomfortable angled position. I groaned, getting up. My neck was sore and my arms ached. I heard my phone ringing. I reached for it, I felt terrible, my head was pounding, my stomach was doing backflips, and my skin felt like it was on fire, and I was immune to fire!

"Hello," I sighed looking down at myself. I wasn't wearing what I was this morning, it seemed a bit different, like another uniform. I'm sure it was something from a shoot.

"(Y/n)? You okay, you sound sick," Nightwing was on the other line, "There are reports of a new villains. I'm already at the cave."

"Right, I'll be there so-" I ended the call as I went into a major, body racking, coughing fit.

I changed into my uniform, dismissing the other outfit. I had been having blackouts the past couple of days, not only that, but I hadn't seen B.E.M since our fight. I think I was just overworking myself, I should count not seeing B.E.M as a blessing.

Before I knew it, I was at the zeta tube. I had counted on my muscle memory to lead me there while I was thinking. I zeta-d to the cave, my head continuing to pound. the once familiar tingly feeling was like bees stinging me everywhere.

"Hey guys," I groaned. Everyone gasped, I knew I must have looked like crap. Dark circles under my eyes, pale skin, I wasn't pretty.

KF and Artemis were gone, out of the hero game for who knows how long since Artemis was pregnant. Bumblebee and Lagoon Boy were gone too, studying or personal things I assumed.

"You don't look so good." Robin pointed out. I snorted, way to state the obvious.

"Maybe you should sit this one out." M'gann suggested. I nodded in response, too sick to argue with her. I trudged towards the caves living room to lie down on the couch. Once my head hit the soft cushions I was out like a light.

Nightwing's P.O.V

I looked at (Y/n) as she left, I was concerned. She was different, since the whole Brain situation. I pulled up a screen showing pictures of the new villain. All of them were blurred and unclear, yet something about her was familiar.

"This is the new villain. She goes by Yin." I reported.

"Yin is the black half of a yin yang," Wondergirl realized, "It's supposed to be the evil, dark half."

"Right," I nodded, confirming her suspicion, "Too bad (Y/n) isn't here, their powers match. Out mission, capture this new threat. She seems to revolve around the Happy Harbor docs."

***************

We arrived at the Happy Harbor docks. The dark water beat against the wooden docks, the moon cast down an eerie glow over the area. I grabbed my escrima sticks.

"Beast Boy, Aqualad, and Superboy, take the water. M'gann, Wondergirl, and Robin take the left side. Blue Beetle, Batgirl, and I will take the right."

We all took off in our separate directions. My thoughts wandered back to (Y/n). She never got sick, what would have happened for her to be this sick?

"Everybody on?"

We all replied with a 'yeah.' I let out a sigh of disappointment. I was really craving some action, things had been quiet for too long. I didn't like that.

"Water's clear." Beast Boy confirmed.

"Left is clear." Wondergirl sighed, it seemed she wanted some action to.

"Right side is cle-" I was cut off by a wave of fire crashing by me, "Belay that we need back up, now!"

Someone stepped out of the shadows. Yin. All of us got into defensive positions, but she just stood there, arms crossed, smirk on her face.

"Look, it's the former boy blunder! And the girl who's only here because her daddy works with her mentor. Then there's you," her voice was high pitched and mocking. She was hiding her real voice. She turned to Blue Beetle, "The one who hears voices, and bonded with (H/n). Is she like a big sister to you? What did you call her? The devils child?"

"Buena maldad," Blue growled, Yin started laughing. A cruel and mocking laugh, like she already knew what Blue called (Y/n).

"That's right! Now, I really have enjoyed talking to you guys, but I have to go before you do. Bye!" She sang lifting her arms up,, disappearing in a flower of flame. I ran forwards, there was no trace of her. I let out a groan of frustration.

She was playing with us. She knew things that no one else should have, and she used them against us, teased us. Nobody should have known these things besides the team, so how did she?

(Y/n)'s P.O.V

I woke up where I was when I fell asleep. I let out a sigh of relief, which turned into a gasp. I was wearing the same uniform type thing again. Red lights began to flash in my mind. I panicked and ran through the zeta tube to Blüdhaven.

I made sure to stick to the alleyways when walking to the apartment. Nightwing and I had cleared out most of the criminals so there wasn't much to worry about.

When I got back I made sure that there was no one around when walking down the hallways and when I was in the elevator. I ran to my apartment, having to try more than once to unlock my door since my hands were shaking like crazy.

"You should have taken my hand." I whipped around, fire dancing on my fingertips. I relaxed when it was only B.E.M, not a member of the team, "Then you wouldn't be having this problem."

"What problem?"

"Your demon instinct is lashing out, but you know what the good thing is?"

"What?" I whispered, fearing her answer.

"You're becoming as evil as the devil, but you're twice as pretty."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So, you can probably guess who Yin is. You're probably going to hate me after this, but I'm still going to continue to write the story! See you next time! Byyee!
