Disclaimer: I don't own Harry Potter, the power rings, or anything else you recognize. Just on the off chance you didn't know that already.

Beginning author's notes: So, there are some things I want to say before readers become confused or annoyed because my story doesn't line up with what they know. First off, I am saying that a wizard's magic will protect them some from the mental changes caused by the ring, because I don't want to write a story about people being completely controlled by their emotions. Second, in this universe there are no superheros born on Earth, and this story describes the first major alien contact. This is a story about wizard getting power rings and using them, not wizards meeting aliens who have power rings. Also, I am making the assumption that the readers are familiar with Harry Potter and will be proceeding accordingly. I would say the same for Green Lantern, but the characters still need to learn that too, and I am not an expert, so you can get away with not knowing it very well.

I'm not going to write something if it doesn't matter to the plot and isn't changed significantly from cannon. I will skip scenes which don't meet those requirements.

Chapter one: It begins

"Harry Potter of earth, you have the ability to feel great anger. Welcome to the red lantern corps."

Harry watched the strange red ring as it floated onto his finger. Then he was covered by a wave of red. When it faded he was wearing a red and black outfit with the same symbol on the chest as was on the ring. He suddenly felt very hot, but not uncomfortable.

"Lantern Potter, you will report to planet Ysmalt for training. Error, unable to locate Ysmalt. Retrieving personal power battery." There was a flash of red and a pure red lantern appeared.

Harry watched the ring, waiting to see what it would do next. When it became clear that it wasn't going to do anything else Harry said "So what do you do, oh magic ring?"

"Red power rings channel the anger of the user and those around them to create solid light constructs, allow the user to fly, use pyrokinisis, and protect the user from harm. They also convert the user's blood to a corrosive substance which is kept at a high temperature by the ring. The user can regurgitate this substance without harm to themselves to use as a weapon. It is also possible for the user to fire blasts of anger from the ring. Additional note, power rings are not magical."

"Wait, it does what to my blood?"

"A red power ring converts the user's blood to a corrosive substance and keeps it at a high temperature."

"Wouldn't that kill me?"

"Negative, the ring protects the user from all forms of heat and corrosives."

"Oh." Harry grinned to himself. The Dursleys would regret how they had treated him. Then he looked down at himself and frowned. "Ring, can you change my clothes back to normal?"

"Affirmative"

There was a moment of silence. "Ring, why didn't my clothes change back?"

"No instructions were given to do so."

"What? Yes I... Oh, very funny. Ring, change my cloths back to normal." His clothes changed back.

Then a thud shook the shack the Dursleys had dragged him to. His aunt and uncle came rushing down the stairs, Vernon holding a gun.

A.N.: Yes, I know it's short, it's just the introduction.
