What stops Slowking with its smarts from telekinetically holding Mr. Sandman in place, preventing him from shapeshifting, spreading out, & approaching? Confusion & Psychic are both telekinetic attacks. (Also, neither of these characters have a justification for their Lifting Strengths, if that's relevant.)
Also, Disable & Swagger might be helpful, and what about Yawn to incapacitate?
Slowking also outranges, with "tens of kilometers with most attacks" versus Crocodile for... making sandstorms that cover cities? Isn't that Environmental Destruction? Still a range feat, but not a helpful long range offense.
Lastly,
SBA says
Preparation time: None. That means there is no time between the character knowing there is going to be some battle and the point they may start killing each other. They are, in a single instant, transported to the battlefield from their everyday activities, equipped with their equipment, transformed to the character version they battle in and given the correct state of mind. In the same instant the battle starts and they may attack each other. They are assumed to not be surprised or disorientated from the sudden start.
Location: Central Park, New York City. The location can be left during the course of battle. If extreme advantages are generated via this location to one side, a balanced alternative should be discussed in the thread.
https://en.wikipedia.org/wiki/Geography_of_New_York_City
"The
geography of New York City is characterized by its coastal position at the meeting of the
Hudson River and the
Atlantic Ocea in a naturally sheltered harbor."
Hey, how far is Central Park from the ocean? Does real world sea water affect Devil Fruit users the same as One Piece sea water?
That said, I doubt it's likely Slowking would try to chuck Crocodile into the ocean; It's a genius sure, but how would it know about it? I doubt Slowking has had enough time in the Real World to binge watch One Piece.
Would Crocodile be conceited/brave/foolish/sadistic enough to mention his weakness to what he might think is an animal?
