She looked at me in a confused way but finally said "Outside of National City".

I now looked at her in the same confused way "There is no National City" I answered very certain that this was true.

"Yes there is, you can see the city from here" she said pointing to the skyscrapers that could be seen in the distance.

I started to analyze the situation and an idea came to my mind. "You know The Flash?" I asked.

"Who?" She asked taken back by the question.

"The Flash, speedster, hero of Central City" I explained. Now she looked even more confused than before.

"There is no Central City" she responded.

By saying that she basically confirmed my theory.

A year ago in the Central City Museum there was an exhibition about a theory called the Multiverse. Basically this theory consisted on the fact that there were infinite universes and infinite Earths existing at the same time on top of each other but since they vibrated at a different frequency they couldn't see each other. In these Earths everything could be different or almost the same but since there is an infinite amount of them there are infinite possibilities as well.

There was never anything that proved that these Earths existed but I think this was all the evidence that I needed.

"How did you get here?" Supergirl asked cutting my train of thought. I spent a few moments debating if I should tell her everything or not, but in the end I decided to tell her the whole story since I truly believed that I could trust her. I don't know why but I just did.

"I think that I'm on a different universe" I sincerely said. I saw her eyes widen and stare at me in amazement for a few seconds before she opened her mouth again.

"You didn't answer my question" she said.

I smiled and said "I was in my city helping a friend fight crime and we faced someone who could basically transform into poisonous gas and I kind of fired a ray in the ground and fell into the hole and I appeared here, in the middle of nowhere".

I saw her smile in excitement and I didn't know why until she said "You are a hero too?"I nodded in response.

She stared at the sky for a few minutes and finally said "So you fight aliens too, wait are you an alien?"

I laughed for a second and then spoke "No I am not an alien I told you before that I am a metahuman".

She glared at me in confusion and asked "What is a metahuman?"

I explained my whole story and my Earths story, the particle accelerator explosion, metahumans, The Flash and about my life. When I finished I was surprised that she wasn't asking any questions.

We stood there in a confortable silence until I heard something come from Supergirl's ear. My guess is that she has a team that helps her against crime and this was her form of communicating with them and viceversa.

After she listened to whatever her team was saying she turned to face me and asked something I didn't expect "Can you help me with something?".

"What do you need?" I answered ready to comply.

"I kind of need your help with a robot designed to kill me" I was kind of puzzled but agreed to help anyway.

The second I agreed she grabbed me and started flying.

It was exhilarating just seeing the clouds pass by my side and at the same time going at an incredible speed. I think she is faster than Barry. After a few seconds of flying she landed and put me on the floor. I was a little dizzy but I recovered quickly.

I looked up and saw a red robot standing in front of us. It was trying to hit someone. When his punch went through the figure I realized that it was a hologram. Supergirl shouted at him until he finally noticed us.

"What do we do?" I asked her.

"We keep him occupied until my sister can deactivate him" I nodded and prepared myself to fight.

I grabbed the Dagger and I inlaid it through my chest and when I did, Supergirl and me started running towards the robot.

The robot was taking the hits from Supergirl and the rays coming from my hand like it was nothing. Suddenly his hands started to rotate generating a mini tornado sending us flying back. We quickly stood up but he was already in front of us, he hit me in my face and I fell to the ground almost blacking out.

I opened my eyes and saw him choking Supergirl when out of nowhere the robot just turned off letting Supergirl out of his grip. I guessed that Supergirl's sister figured out how to deactivate him and that this fight was finished but I couldn't be more wrong.

Supergirl looked at me smiling until the robot was turned on again.

"It's gone rogue" she shouted at me and through her com while I stood up as quickly as I could.

The robot was slowly walking towards Supergirl when she used her lasers vision and landed it in the robot's chest but he was unfazed by this and continued walking towards her.

I saw how Supergirl intensified her laser vision and it still wasn't enough, the robot was still slowly approaching her.

That's when I realized how I could defeat him. My dagger exited my body and entered my hand transforming into the shining sword I saw before.

I ran behind the robot and sank my sword through his head and his body cutting him in half.

The two halfs of the robot fell to each side and he was finally defeated.

I looked up to see Supergirl exhausted, kneeling on the floor. I ran to her, while my sword became a dagger once again, and helped her get up.

She looked up at me and smiled

"Thank you" she said after a few instants.

"No problem, but if you have another robot trying to kill you please don't call me" I responded making her laugh.

"We should go back to the DEO" she said.

"I'm sorry but I have to go, I have to try to find my Earth".

She looked sad for a minute until she asked "What is your real name?"

"Tomas Steller"

"It was nice meeting you Tomas" she said while giving me a handshake.

"It was nice to meet you too Kara Danvers"

How did I know her real name? She didn't even tell me that.

"How did you.." she started to ask but the sound of my ray hitting the ground cut her off. This time a portal had formed.

I looked at her one last time and jumped into the portal not expecting where I would end up next.
