First up, DC and Marvel characters! These are pairings from DC and Marvel comics. Crossovers (between universes or other fandoms) are cool.
Please remember to format your prompts correctly for the ease of the codemonkeys.
X-Men, Scott/Rogue, victory not easily won
Batman, Dick/Tim, sparring
Don't forget more than one writer can respond to a prompt. You may leave more than one prompt, and you can answer your own prompts.
And if nothing here is to your costumed superhero liking, feel free to check out the lonely prompts and rescue one of them.
