I do not own Harry Potter and The Green Lantern serie, this is fan fiction only

Harry arrived on Oa and was looking around when he quite literally bumped into something big. "Excuse me, but I just flew in and boy are my arms tired." Some of the other Green Lanterns actually laughed at how awful the joke was. "Oh, we got a comedian do we, well listen up poser I am Kilowag and for the next hour I am here to test your skills."

"Let's start with something fun for me and painful for you. " Kilowag must have little chance for actually get rid of his stress as he was fighting to actually almost kill Harry. Harry on the other was just yawning and looking bored." Look gorgeous is you are my welcoming party thanks, I really needed to feel welcomed. After all this fun and games are over maybe I can find someone to give me a decent workout. "

Kilowag was now mad and he was no longer trying to kill him, he was making a concertive effort to actually kill him. Harry just kept taking what he was shot, thrown, dropped and flung at him and deflecting it into nothing and looking quite bored while he did it. It was when a young lady was accidentally hit by something he threw that he decided to switch from defense to offense.

"You want to test me, that is one thing gorgeous. But you hurt an innocent because you can't back up your words with skill, now I am mad, and you listen worm you harm an innocent before me. You will wish you died right there and then, by the time I am through with you. Pray to whatever God you worship, cause you are going to need help to survive. "

Harry began with his wolf pack constructs pining him to the ground with their fangs sinking into his legs in a rather painful way. He then made a pair of nasty claws and they put themselves on him like gloves, from them he shot a beam of energy that broke his arms trying to block it.

He then summoned a huge multiheaded dragon, the thing made the other Lanterns watch as he walked over to the badly beaten Kilowag and sneered at him. "Before I send you to your maker, how about you apologize to the young lady you injured."

Kilowag had never seen someone display such destructive constructs just after a young lady was injured. "I think that will be more than enough of that. I see I will not regret being mentor to this human, he hated seeing an innocent hurt as much as I do." Kilowag moved his ring and somehow the young lady was actually a construct he made.

"I just wanted to see how you reacted to seeing that. I never hurt an innocent unless it is beyond my control. I just wanted to see how you reacted to seeing something like that happen. But Damn these things have some nasty teeth on them. Now the one that needs medical attention is me. "

Harry nearly kicked himself for not noticing the young lady was an actual construct. He walked over and with his ring he made a particularly powerful ball of energy appear and he threw it at him. When it hit him all his injuries began to heal at an accelerated rate.

"So the guy I will mentor knows magic, how quaint. I am your mentor, you may call me Sinestro. I been sent by the Guardians our leaders to go with you on patrols and show you how the Corp protects the innocent. Any questions before we get started?"

Harry walked over and looked at him with an almost surprised look on his face. "I am called Harry Potter, and I do have a few thank you. First who is protecting my sector while you mentor me? Second do I have to report to our leaders and last it is a bit personal, ever since I got this ring I had dreams of a woman with long red hair and purple skin, I think she is also a member of the Corp do you know her and where can I find her? "

Sinestro was doing something he rarely did, he was smiling. Kilowag looked like it was the sign of the apocalypse. " Your sector will be assigned to you after I finish mentoring you, but if they had done so before a temporary protector would have been assigned. To the second you will need to do a patrol first and find something or accomplish something worthwhile for you to meet with the Guardians they are very busy and hate to waste time. "

Sinestro smiled and laughed as he walked up to him." Yes, I think I know who you are talking about, if I am right it is none other than Laira Omoto I don't know if I should pity you or ask you if you have contacted your next of kin. She is reporting with the Guardians at this moment, something about killing a criminal that she was supposed to capture alive. "

Harry made a construct of the picture he had next to his bed. " I think this is her. " Sinestro had to admit he never did see Laira in such a way before. She looked breathtakingly beautiful and sweet. It was a complete opposite of how he remember seeing her last.

"Those dreams mean that your ring took the trouble of looking into your future and found you a mate that was more than likely your mate. I found mine the very same way, I couldn't be happier than when I am with her." Kilowag just had to get something in the conversation.

"We have much ground to cover and no time for discussions on the Rings matchmaking habits. We have a band of slavers to deal with, Come on Potter you would not want some poor innocent person ending up living as a slave because you took time to chat about your potential love life. "

Sinestro and Harry took off towards the last known location of the slavers. On the way he asked if there were any special objectives, Sinestro said to keep computers and database storage units intact if possible. It turned out the ones in their base were kept in good shape.

The ones aboard the attack ships, not so much. Harry truly began to send everything he could muster against them. He blasted the ships of the attacking slavers to a million pieces. It was when they boarded the base he began taking the weapons of the slavers as they attacked him and he killed them with their own weapons.

"No mercy to these slavers, I see that you and I will get along well. Why do you not give them a chance to surrender?" Harry looked at him with a rather cold look in his eye. "And give these scum the chance to turn around and stab me in the back? I think not."

The patrol ended an a whole lot of young women seem to be trying to get a little more than friendly with his mentor than with him. Looking at them someone else might feel a bit envious if not outright disappointed in the girls selection, but not Harry. When they both left Sinestro had several kisses showing on his face, and Harry was smiling at him.

"Thanks, Sinestro. I don't think I would survive if Laira ever saw that many young women kissing me. " Sinestro clearly had a sense of humor he kept hidden as he made a tissue appear and cleaned the lipstick off his face. " Assuming she does like you the same way you obviously like her. I was glad to salvage your chance at finding happiness or finding out sometimes the thing we want is the one to cause us the most pain."

The two did a few more patrols before they received a summon to appear before the Guardians. It was clear that they wanted to tell their newest Lantern something that they did not approve off. "Sinestro mind if I ask you a question?" Sinestro hearing the tone of his voice became very stoic and serious.

"I am your mentor Harry, feel free to ask anything within reason of course. " Harry looked at him and then his ring. " Do the Guardians use the Rings to look at what we do? Or do we have operational privacy till we chose to report the results of our missions? "

Sinestro knew where he was going with this, " Yes and No, they created the Corp and all the things we use so yes they can learn what we do with our rings and even about us when we use the power of our rings, but No they would not discuss our patrols with anyone else."

"I get the feeling that they will not approve of my handling of the Pirates, or the Slavers, or those Organ thieves, or the Cultists, or...basically any of the people we had to fight. " They both landed on the platform where all the Guardians looked at him." Actually we did not mind your rather vicious way of dealing with them, the stories by the survivors will be a nice deterrent for future acts. "

" What we would like to know is how can you he in such heavy combat and you still have not recharged your ring even once? Not even when you were on your birth planet." Harry stepped forward and took a small rock and transformed it to crystal. "I am a Mage, magic energy flows through me from my core. I found early in my contact with his ring it uses the same energy I have for my magic, I did recharge my ring, it is just I never recharged it using my Lantern."

Sinestro was speechless as he said that to the Guardians and they looked down at him and smiled. "Thank you for being honest with us Lantern. " Harry bowed to them as a sign of respect. "I would do no less Guardians."

The two left as soon as they were allowed to leave. "To think a human was the first to figure out what was the energy powering their Lanterns and their rings. I think we should keep an eye on him, if he could figure it out as a child, there is no limit what he might do in the future."

Laira was flying up to them and she somehow did not look that happy to see him. Sinestro excused himself using the excuse that he did not want to intrude in a private conversation. "Kilowag just told me you have a picture of me, and you had it since you made it after you saw me in a dream years ago. I demand to see this picture and if it is scandalous I will make you pay for embarrassing me with my fellow Green Lantern."

Harry made the construct appear once again. It was the same picture he had next to his bed, the one he kissed every morning and every night as he went to sleep or woke up. Laira was looking at it and she could not help but to blush as she saw it. "This is a picture I had drawn of me when I reached adulthood. It is a picture I have never shown anyone. But even that picture does not look as nice as this, why do you have it and what did you do with it?"

Harry floated next to her and he banished the picture. "I had a dream of a beautiful lady and I fell in love with her, I drew this picture so that I could greet and kiss my beloved each morning and each evening as I went to sleep. This was my only joy in my life. To think that somewhere she might one day feel the same for me. "

Laira did not imagine this answer, she imagined he used it to picture her doing lewd and sexual things to her as he masturbate before going to sleep, but not something so endearing and romantic. " Tell me one of these so called greetings. "

He looked at her and did as he did so many times before. He looked at her and smiled," I bid you farewell and good fortunes, till the sun illuminates your beauty once again. I wish you sound sleep and happy dreams Laira, my love. "

Harry left and he headed towards the place Sinestro was clearly waiting for him. Laira never heard someone say such loving words to her, she could feel her face blushing, and her heart racing." To think someone I never knew loved me so much and all because of a dream. I guess I was not the only one who had a dream like that. "

" So did you tell her a nice romantic poem and declared your love for her? Or did she threaten to beat you to a bloody pulp if you tried?" Harry smiled at Sinestro. "Those ears have a long range it seems, but not so big on clarity. I only answered her questions and showed her the picture I drew many years ago. Mind telling me where do I sleep or do I have to construct a hammock between two buildings to catch some sleep? "

" As much as I would love to see you try to sleep during morning traffic, no. I waited to show you your assigned domicile, I am your Mentor, looking out for my charges best interest and safety is both my privilege and my duty. "

Harry had to admit it was rather nice place if not a little empty at the moment. But he figured that being a Lantern he could make more furniture from his ring as needed." I will see you tomorrow and early, we have more things for you to learn. " Harry wished him happy dreams. Sinestro had to admit he liked the human named Harry Potter.

" At first I felt that Abin Sur's ring chose incorrectly and that this human would not be up to the level of our Corp, but he shows sense of defending the innocent and the intolerance of evil that he did long ago. I guess he will be as much of a good influence on me as I hope to be on him. "

Laira decided to change her clothes to sleep and she looked at a picture she too drew long ago. It was not as stylish or clear denied as his but she could tell it was Harry by the scar that both he and the picture had. " Sweet dreams, and safe returns my love."
