Monday: Crossovers

[gladdecease]

Buffy Summers, Captain of the USS Enterprise. The X-Men joining the Justice League. Shinigami meeting Death himself.

That's right, today's theme is crossovers! Take two series and make them meet, in whatever way you like.

Just keep the rules in mind:

• No more than three prompts for the same fandom.
  
• No more than five prompts in a row.
  
• If one of your prompts is filled, you can prompt again.
  
• No spoilers in your prompts for at least a week after the airdate/release.
  
• Warn for any spoilers for your fic in bold and leave at least three spaces before the text.

And don't forget to save our code monkeys some grief - follow the format!

Doctor Who/Sherlock, Ten/Sherlock, A Study in Time
Supernatural/Death Note, Castiel + Ryuk, not any Reaper he'd seen before

None of these prompts catch your eye? Don't forget about our Lonely Prompts!
