Just a little something, that wouldn't leave me alone. And because I love the idea of crossover ST/Doom (why I didn't think of that before?). You think there's a chance they make one in the new movie?

Anyway, like it's said in summary: It's not slash, but if you want it to be it's your choice.

DISCLAIMER: I don't own Star Trek or Doom and it's characters.


Jim let out a long, resigned sigh and - because he didn't have nothing better to do at the moment, really - lightly carded his fingers through the hair of the body sprawled halfway across his lap. His action was rewarded by a contented sigh and a strange soft noise, which made Kirk look down with a frown.

"Did you just purred?" the Captain asked incredulously.

"Shut up," came the growled reply.

Not a bit fazed Jim curiously ran his fingers through the dark hair again. Yup, definitely a purr.

"Aww, Bones," Kirk said barely containing his laugh. "I didn't know you had it in you, with all the bitching and grumbling."

McCoy turned his head to glare up - pupils blown so wide that there was none color left - at his supposed friend-temporary turned into teasing pillow.

"It's your damn fault!" the Doctor accused.

"I know, I know," Kirk placated and added extra stroke to the hair for effect. McCoy closed his eyes and unsuccessfully tried to stifle next contented purr. Jim chuckled. Dammit!

"Captain."

Kirk looked up at his First Officer, "How's the situation, Spock?"

"Under control. The monsters were... incapacitated due to the effects of the substance and there were no problems dealing with them. Now we're sweeping the area to determine if there's any of them left."

"Good," Jim unconsciously petted McCoy again.

Spock's both eyebrows disappeared into his hairline at the happy noise, "Fascinating."

Kirk grinned.

"I swear, once this is over I'll kill you," McCoy growled. "And you're banned from any lab there exists."

"Bones," Jim sighed exasperatedly. "How I was supposed to know that this particular compound is like a catnip for super-humans?"
