VS
Deadpool

Conditions:
Due to the fact these two have some of the best healing factors in marvel, this battle's victory is marked by "till bested in combat, incapacitation, or KO". whichever might come first. For example, if one party is injured so badly they would need to allow their regeneration to heal themselves before continueing, then the battle would be over and they would have lost. So none of the "deadpool can't die" bologna.
Random encounter, no prep
Location: Madripoor.
Equipment: deadpool has standard equipment he normally has on his person, but does not have his magical gun bag that has access to all weapons.
Standard morals.
And of course, which do you prefer and why?
