AN: Okay, so this is my first Sherlock-Batman crossover, so please go easy on me. I go this idea after watching Batman: Under the Red Hood, and lots and lots of Sherlock. I was wondering, what did Jason do the whole time he was planning his revenge? Surely he wasn't hiding out in some abandoned place the whole time. So, I got the idea to make him and John Watson the same person. I'd love it if you'd give it a chance. John's history has been changed quite a bit, Jason is twenty-years-old; he was fourteen when he was murdered and it is six years later. John will be very OOC, but I am pretty sure Jason will be spot on, since he will definitely have anger management. Sherlock will be fascinated with Jason, because he can tell he has undergone some kind of trauma, but he is still trying to deduce what. This is purely a friendship fic. I don't intend to include slash.

Jason's POV

Falling at least fifty stories after being blown up and resurrected is not fun, but I didn't really care or notice right now.

My heart feels like it is going a thousand miles a minute, but somewhere where logic remains, I know that is impossible.

I hit the ground, re-breaking bones that had only just healed. I instinctively begin to set them, and wonder where the hell I learned how to do that.

I push myself off the ground after making splints, and look for a cave to spend the night in.

For some reason, I like caves.

I started to remember a few days later.

My name is Jason Todd; I was Batman's protégé, his second Robin. The Joker murdered me, with a crowbar and explosives. I am fourteen-years-old.

Before joining Batman, I lived on the streets, hijacking people's tires to live. My mother had been a heroine addict, and my father was an abusive monster who went to jail and died there.

Good riddance.

I snuck into town at one point, and learned that after my death, Batman did not kill the Joker; he just put him back in Arkham.

How could he? If it had been Bruce that had been beaten to a bloody pulp and blown-up by that psychotic freak, I swear, that clown would be dead!

Did Bruce just not care? Did he never really love me at all? Well, that would be just like him, considering Dick, his first Robin, rarely even visits anymore.

I would have my revenge. If Bruce would not avenge my death, then I would.

But, I have to remember; Bruce is Batman, an expert detective. I'd need a new name, and I certainly couldn't run around as Robin anymore.

Maybe I should go by my middle name, Peter. No, too obvious; Bruce would get it. Perhaps something else that started with a J? Maybe… John?

I'd need a last name too. Couldn't be Todd anymore. But… what was my mother's maiden name? Watson. John Watson. Yeah, it worked. I don't think B even knows what my mother's maiden name was, and if he does, he probably won't put it together. Maybe if I chose Peter Watson, but I didn't.

I'd have to forge documents for that, but hey, I didn't get Bat training for nothing.

Now as for my new vigilante name… it would have to be something that I could shove in the Joker's face, yet at the same time get both the freaky clown and Bats to notice me, when I want them to, of course.

The Red Hood.

The Joker used to use that name himself; it'd be perfect.

Now, all I need is a costume.

AN: Well, did you like it? I hope you did. I read this really good fic where John was made into Remus Lupin from Harry Potter, which is actually where I got the idea to make it so Jason was John Watson. I was hesitant to do it at first, but after reading that other fic, I thought what the heck?

I hope you enjoyed this; let's all hope that Sherlock does not drive Jason insane. He just got away from one detective, and now he is with another, and we all know Jason can only take so much before he shoots someone. :)
