Thanks to guest reviewer Jeremy for his suggestions of a title for this story! His suggestion of "The Right Side of History" inspired me to think of the current title. ("Deep Space Avengers" was decent, too, but seems more appropriate as a general series title for both crossovers. Plus, I never thought The Avengers was entirely accurate as a title for the show — what are they avenging? — so I don't think I'd use it as a story title.) Thanks again, Jeremy! Barbie

A/N #1: When I watch a movie or TV show, the characters' voices have a tendency to get stuck in my head, making it hard to think out any other story. I was really into Deep Space Nine, but after watching The Avengers, everyone sounded like Steed. Rather than try to fight it, I came up with this crossover. A few weeks later, I found out about Dr King for the first time, and realized adding him in would explain Bashir's lack of immediate action when someone was shot. Barbie

A/N #2: This story follows the timelines of my Deep Space Nine and Avengers alternate histories, but I don't consider it to have actually "happened" in either story. Normally I try to avoid mentioning Bashir's enhancements, even in narrative or his own thoughts, until after they're discovered (even in my story of that discovery, I'm going to avoid mentioning it until it actually comes out, though I might have more hints than usual!). It's fun putting in things where if you don't know Bashir is enhanced you won't guess, but someone who does know (which is probably everyone!) would realize that's what Bashir's thinking of or how he could do something. But in this story I was having trouble not referring to it more directly, and I decided that since it (probably) didn't really "happen," it was all right to make an exception to my rule. Barbie

Prologue

Deep Space Nine Season Four

John Steed moaned, opening his eyes and squinting against the light, the brightness making his head pound. Where was he…? The last thing he remembered was that alley, but even with blurred and double vision he could tell that this was no alley. There was a sterile, futuristic look to it, accentuated by the computerized hum in the background…or was that his ears ringing?

He must be badly hurt; his chest ached sharply and he could barely breathe. He had to get out of here…had to find a doctor…

But as he attempted to move, pain exploded through his whole body. With a gasp of shock, he lost consciousness once more.

First chapter coming next week!
