Deadpool (Marvel) vs Ranma Saotome (Ranma 1/2)

Deadpool finds himself in Tokyo (at the very end of Ranma 1/2, after the final volume), with the job of either a) killing Ranma, or b) kidnapping Ranma and taking him to Cable's floating island.
Ranma, somehow, knows a little about Deadpool and expects him to show up eventually. Ranma can't run away and must find a way of stopping Deadpool before Deadpool gets him.
Ranma either a) must face him alone, and is free to use his forbidden techs, or b) have one or more of his 'Friends' or 'family' show up to help.
Does Ranma stand a chance? And what happens to Deadpool? What happens afterwards if Deadpool succeeds?
This is a in character battle (personalities active), and the laws of the Ranma Universe are in effect.
