Summoner of Strawhats SOP

Earthling crashes dimensions and gets thrown onto the deck of the straw hats. As he is weak he bets on his future knowledge to survive.

He will have a special power, that he will find out later.
He will not be totally selfless and a bit manipulative, but no human is perfect in the face of their desires.

It started with me sick and bored in bed with only my phone to write on.
