I knew about the Ant Queen even before I found that factory. There's a mision wher you can help a Fire Ant infested town an you see an Ant Queen while doing that, (you don't kill her though.)
The only time I was surprised in Fallout 3 was this:
I was wandering the wasteland. I came across a Deathclaw and a Robobrain fighting. It's pretty obvious who's going to win this and sure enough the Robobrain toppled over. While doing this though it somehow catapulted the Deathclaw straight into the sky. I hung around the area for a while, mostly because a group of Enclave needed to be killed. Killed them and looked back to wher I came from, looked forward again, heard a noise so looked back and WHAM! Angry Deathclaw lands almost right on top of me. Gave me a damn fright too.
Deathclaws are easy though. I built myself the dart gun. One hit from that and their movement slows to a crawl and they're easy to take care of. Same with those bear things too.
