This is my first crossover fanfiction idea. Leonard and the gang have always loved superheroes (maybe not the girls), how will they react when they find out that superheroes are real? Also, Sheldon and Amy discovered that dust contains Dark Matter, and the gang's new friend Emma isn't all she seems. Also when there is a new character's name in bold it means that scene is from their point of view.

Disclaimer: I don't own any of the characters from any of these TV shows.

Kara

"You want me to what?" I asked Cat, she'd called me and given me my next assignment.

"You heard me, I want you to interview recent noble prize winners Sheldon and Amy Cooper." She repeated.

"What's interesting about that?" I asked, good news stories are always meant to be interesting.

"I think your friend Lena will know excactly what I'm talking about. Don't forget to update me." She said, then ended the call. I looked at Lena, who had definitely been listening the whole time but now pretending she hadn't.

"What was all that about?" She asked.

"Cat asked me to interview Sheldon and Amy Cooper." I replied.

"The noble prize winners?" She asked.

"Yes." I replied.

"They're such a big deal in the science world! You have no idea! They're the first scientists to solve string theory, and believe me, people have spent a long time trying to figure that one out." She told me.

"Do you want to come with me?" I asked.

"Seriously?" She asked.

"Yes, you understand this stuff more than I do and it's a perfect excuse for a road trip!" I exclaimed.

"Alright, let's go!"

Sheldon

"And that is why Babylon 5 sucks!" I concluded.

"You can never win." Leonard muttered, he's right, you can't. Someone knocked on the door.

"Penny." I blurted accidently.

"We're all here." Hally whispered. We all looked at each other, wondering who we were gonna make open the door.

"NOT IT!" Everyone except me yelled. Damn it. I can't believe this is how I'm going to die, I thought as I walked over to the door. I opened it.

"Are you Sheldon Cooper?" The blonde woman asked.

"Yes." I replied.

"Great! I'm Kara Danvers from Cat Co Worlwide Media and I'd like to interview you and your wife about winning the Noble Prize."

I found this very strange, for one thing, me and Amy won the Noble Prize 5 years ago. For another, Kara Danvers is a much beloved fictional character from the DC Universe.

"Okay... come on in." I told them, then I realised there's another lady standing next to her.

"I'm gonna need a little context here." Leonard said.

"I'm Kara Danvers from Cat Co Worlwide Media, I'm here to interview Sheldon and Amy Cooper about them winning the Noble Prize." Kara explained.

"Oh. But that was 5 years ago." Leonard pointed out.

"My thought excactly." I said.

"Is Cat five years behind?" Kara's friend asked her.

"No... I don't know." Kara replied. "I hope you two don't mind, I'd probably loose my job if I didn't interview you." She added. I looked at Amy.

"We don't mind." We told them in unison.

"Great!" Kara exclaimed. I sat down at my usual spot. I gave Howard and Raj a look.

"We can go and sit in the kitchen." Howard said, and they did. Kara sat next to me and her friend sat on her other side.

"So when did you guys solve String Theory?" Kara asked.

"Oh! That's a cool story! Me and Sheldon were getting ready for our wedding and it just came to us. The guests were waiting while we were solving science's greatest problem." Amy replied.

"That does sound awesome." Kara's friend said.

"I'm sorry, but who are you?" I asked her friend.

"I'm Lena. Lena Luthor." She replied. This can't be a coincidence.

"Did you just say Lena Luthor?" Leonard asked.

"Yes." She replied, sounding confused.

"Why are you all acting weird?" Penny asked. She doesn't get it, characters we know and love seem to be real. Suddenly there was another knock at the door.

"This evening is getting carazy!" Amy exclaimed, she's right, we've never had this many people over.

"NOT IT!" Eveyone yelled.

"Damn it." I muttered, and for the second time this evening, I got up and opened the door.

Emma

"Hey Sheldon!" I exclaimed. I still can't believe I managed to become friends with him. It's hard... I have to lie to him because he won't belive my truth. Not at first...

"Emma, my, this evening is full of surprises!" He remarked. "Social conventions states it's polite for me to invite you in. So... would you like to come in?" He asked, I smiled.

"Yes Sheldon, I would." I replied.

"Amy's right, this evening is carazy." Sheldon muttered. I followed him inside and felt the atmosphere in the room change instantly.

"Why are they all staring at me?" I asked.

"They've never met you before. Also Howard thinks your hot, he's drooling." He replied, I looked at Howard, Sheldon's not wrong. And gross! Thankfully Bernadette punched him on his arm. Everyone laughed at that.

"So, Sheldon, I think we're all gonna need a little more context here." Leonard said.

"Alright, I met Emma at work." He explained.

"And... what? You used some weird voodoo spell on her?" Raj asked, and giggled.

"Don't bad mouth voodoo!" The girl who I'm assuming is Penny exclaimed.

"She's right Raj. You shouldn't say anything against bla- voodoo." Another girl agreed, there's something familiar about her... I can't put my finger on it.

"For your information. I like Sheldon, and he's a rather pleasant companion. The only normal companion I've had for a long time." I blurted, I'm not going to be able to keep up this charade any longer.

"I'm not deaf right?" Penny asked.

"We should probably go." A new voice murmered.

"No no, please stay. You haven't finished interviewing us." Sheldon pleaded.

"Alright, where were we?" The same voice asked.

So let me know what you think. I won't be able to update much with exams coming up. But I'll try to as regular as possible.
