I like the fact that you didn't choose a specific doctor to be here. And that The Doctor himself has dialogue that can fit anyone of the 13 we have so far, never mind Eighth being a nice guy, Fifth too shut-in than the others or War busy with the Time War.
Good choice. Poor Necrons, though. Of course it had to be in Dune.

"Welcome, oh proud Necrontyr, to Arrakis."

Wait...

You sonofabitch. You brilliant sonofabitch...

All I can say is thank you for showing the Necrons that The Doctor should be Feared, and that time is not to be tampered with

ArchAIngel Attempting to do so would result in the C'tan in question being bitchslapped by either an Eternal or the White Guardian.

The spice is life! Also, the doctor is not that powerful. And the C'tan could wipe him from existance with a thought.

Its allways nice to see the Doctor being badass, and casually putting ancient, powerful and overly arrogant baddies in their place. A very enjoyable oneshot.

Thus proving that the daleks are better than necrons. :)

I think that you did a suburb job of capturing the character of Matt Smith's Doctor (I'm assuming that it's supposed to be the Eleventh of the mention of the fez).
I don't know exactly what Arrakis is, but I take it that it isn't a nice place... for a Necron, at least.

I'm unfamiliar with DW who is the local?

you dropped them on "DUNE" huh

necron meet sandworm

Very, very nice. I wish I knew what, precisely, a Necron was, and the significance of Arrakis, but you relayed their danger quite well, and captured the Doctor's voice VERY well. I can't quite tell, though - which Doctor is it? I'm guessing Eleven, but I'm not 100% positive about that. Anyway, great job, and thanks for an enjoyable read!
