BTAS/Marvel Universe. (Because Hamil Joker all)
"Well what do we have here, a bright new world rich for the plunder, and not a soul who knows who or what I am" The Joker grinned as he looked down over the new york warehouse he had "acquired" from a chap claiming to work for a Kingpin, well who ever this Kingpin was, he'd see the joke soon enough.
Had it been any easier to acquire the machinery and chemicals he'd needed to make his mark upon this city he would have laughed, in fact, now that he reflected on it, why should that stop him, the manic laughter that would turn most Gothom born men and women fleeing rang out over the New York docks, garnering no more response than scattering a few cats and partially distracting a passing Spider-Man, who after near careening into an on coming bird, decided it was not worth incurring MJ's wraith to find out what was so funny, after all, laughing wasn't a crime.
"But puddin' what about all these other costumed creeps who this place has flying around, won't they come running once we start spreading the smiles?" oh Harley, she always found a way to bring him out of a good mood, but not today, oh no not today.
"But that's the best part, new heads to mess with, new heroic heartstrings to pull, oh this will be such a blast, just thin~"
The energetic rant was cut off as the entire building exploded, the mix of carefully placed charges and the volatile chemicals made short work of it and it's occupants, it was this noise that finally got Spider-man to turn round and take a closer look.
Miles away, watching the explosion through a pair of binoculars, was a man clad in black and red from head to foot, swords on his back, guns at his hip.
"And Boom goes the dynamite, Deadpool, wins."
"What? Just cause I'm in a crossover doesn't mean I have to play fair?"
