Ask to join the League

So after you've all finished your meal, you head towards a chamber where most of the League are waiting, on the way there you ask Batman whether you can join the League, he replied that he'd bring it up at the meeting.

When you get there the members of the League all sat in a large room, of course you're fully aware that if you make a wrong move they are all ready to attack, but you don't plan on moving anyway.

As you expect Superman asks the team to brief him and the rest on what happened during the mission, Batman explains in detail what happened at the lab, your escape, your acceptance to come along quietly and your curing of Zatanna's cancer.

Superman asks how you knew she had cancer, and how you cured it, you reply "the doctor built me with the primary purpose to destroy the League and help him take over the world, this you know, what you don't know is that he wanted to make sure he lived as long as possible, if he took over the world he wanted to make sure he wouldn't have to rely on the help of others, knowing that in all likely hood, they would betray him and perhaps kill him themselves, so while most of my abilities are used to destroy, I also have the ability to heal myself and others from nearly any ailment or injury, I could heal most diseases, or I could heal a wound, I could not however make someone regrow a lost limb or heal psychological damage or neural degeneracy such as Alzheimers."

"how close do you need to be to read someones illness?" "no more than 1 meter away"

"do you have any weaknesses?" "Unknown, and if I did know, I wouldn't tell you, though I would trust the knowledge with Batman, if I had it"

"Why do you trust Batman, not that he isn't worthy of trust, but why do you trust him?" "He relies on skill and intellect to defeat his opponents, unlike you who is all power and no skill whatsoever"

This reply seems to irritate Superman, though out of the corner of your eye you see a smug look on Batmans face.

"what do you mean I fight with no skill?"

with that your body begins to glow red

"I am limiting my strength and speed to a human level for someone my size in good physical condition, if you can defeat me in combat, I will reveal all knowledge I have, if you lose you must get combat training from Batman"

"very well", he walks down to the stand that you're on, it's roughly 20 feet across, large enough for a small arena

"the rules are simple, whomever get's knocked out of the arena first is the loser, only physical attacks are allowed, to make it a fair contest I have limited myself to a human level of combat strength and in turn you may have noticed that this red glow I have affects you the same way a red sun would, completely non-lethal, but renders all your powers moot and brings you down to a human level, like me"

"very well then, the others will observe to make sure you're not cheating" "agreed"

For the first couple of minutes you watch as superman throws punch after punch at you, occasionally throwing in a kick or two, you dodge every single on with your hands behind your back, eventually he throws a long punch in frustration, you grab his arm and throw him over your head and out of the "arena".

Superman acknowledges his loss and agrees to take training from Batman, "it was a moot point, I knew you'd lose, I have already told everything I know about why I was created, and the others already told you that I rejected my 'creator'."

Back in his seat superman asks "so what should we do with you now?".

You look to Batman "he has requested permission to join the League" "what do you think Batman?" "even if I didn't think it was a good idea, which incidentally I do, he hasn't done anything illegal or morally questionable."

"Alright then, let's put it to a vote"

After all votes have been tallied there are 60% who agree to let you into the League

"the motion passes, welcome to the League Necro"
