"Don't move! Put your hands behind your head now!"

I looked around and saw that I had been surrounded but I knew that they were all human so I wasn't worried about them actually being able to hurt me, at least, I wasn't until I got hit hard by someone that had just flown in through the open window behind me.

"At last, a challenge."

As soon as I saw who had hit me, I realised exactly where and when I was.

"You're the one they call Supergirl, right?"

"How do you not know who I am?"

"Before I answer that, I have one simple question. What earth am I on?"

"Wait a minute, you're from another reality? Why are you here?"

I thought for a moment before deciding I had nothing to lose by being honest with them, they may even be able to help me get home.

"I was sent to another earth to aid them with a powerful being that had fled there from my home and started trying to take over, they attempted to send me back to my reality after he had been defeated but for some reason, I ended up here instead. When this has happened in the past, it was always because I was needed for some reason, like a powerful threat that the people would be unable to deal with on their own or possibly for some other reason."

I could see that they were worried when I mentioned the possibility of a powerful threat but I was quick to reassure them.

"I may not know yet why I am here, but if I am here and there is a threat, then I am confident that we will be able to defeat it if we work together."

A few moments later another alien flew in through the window and landed in front of me.

"Is this the new arrival?"

"You are martian, I assume you were called to probe my mind to see if I was telling the truth about who I am and why I am here?"

"Indeed, you are not offended by this?"

I laughed for a moment before responding.

"Of course not, it is only sensible for me to prove that I am telling you the truth and that I am no threat. I will lower my shields and you may see what you think, I would ask that you not look into my childhood though, I experience everything that a psychic sees and I do not wish to go through those memories again."

"Very well, simply focus on the true reason for your last mission and the truth of what you told them and that will be all I will need to see to tell whether or not you are telling the truth."

"Very well, I sense that I can trust you, so you may enter my mind and search to your hearts content."

I don't know how long he searched through my memories for but when I returned to the real world it was still quite bright outside so it couldn't have been long.

"He speaks the truth, his people seem to have been created as protectors, though there are some that have gone against their creators and seek to control, rather than protect, he is one of those that is sent to stop them when they appear."

"But how can he stop them? If they are that powerful that we would need help to beat them and I took him down with one shot, he can't be that strong."

I looked over to supergirl and smiled.

"The only reason you landed that hit on me was that I was distracted, if we were in battle, that would not happen and you would most likely be defeated already."

I could see that she doubted that so I decided to try and see what she was truly capable of.

"I can see that you don't believe me, is there an out of the way area we can use for a little sparring? Preferably several miles away from any people or towns, less chance of damage that way."

"Very well, we will meet you outside the city at this location, we have used it before for her training so we sealed off the whole area and marked it as a test site so no-one else goes there."

As he spoke he showed me a map and told me how to get there and once he had finished I headed over to the window he had used to enter and changed into a form I knew could travel there faster than the human eye could follow and flew out of the window, laughing to myself when I heard the surprise of the people in the building I had just left. When I arrived at the place that they had told me to head for, I saw that none of them had arrived yet so I found a flat rock and sat down to wait for them.

When they arrived they seemed surprised that I had got there first and asked what I had changed in to as I left.

"Well, it's a creature from my home-world, we call it a shadowhawk, it seemed the best form to use since only a few people would have been able to see it once I got in the air. I figured it would be best if I remained unseen as much as possible, just in case whatever I am here to stop saw me and realised what I was."

"A sensible precaution."

"Yes I thought so too. Well then kara, shall we begin or do you need time to prepare yourself?"

a few moments later she said she was ready and stood a short distance from me.

"Before we begin, the rules. All powers are permitted except for flight, I want to see how you fight on the ground first, perhaps next time an aerial duel could be arranged."

as she took up a position i removed most of my armour and set my weapons to one side before preparing myself for the challenge ahead.
