Invading Marvel with the Pirates

How far would Spider-Man grow if he had the String-String Fruit and Observation Haki?

How powerful would the Hulk become if he ate the Rubber-Rubber Fruit and learned Armament Haki?

And if Black Panther ate the Cat-Cat Fruit, the true King of Panthers would be born!

Iron Man: Lin, give me a Devil Fruit! I'll trade you 30% of Stark Industries!

Lin Yi: No problem. Give me 40% of the company, and this Gold-Gold Fruit is yours.

Of course, the Devil Fruits don't come for free. Every time Lin Yi gives one away, his own strength grows too.
