((This Au has 2 One Piece theories with it. The First Theory is that Crocodile is Transgender, female to male, and the Second is that Crocodile is Whitebeard's Daughter. And you call Crocodile 'Papa' or 'Dad'. This can be at whatever time line.))

You are Crocodile's Teenage child. He Adopted you many years ago. You are on the Desert Island, you and your Papa live on. Crocodile had to leave for a few days, since he has Warlord Business he had to take Care of. But he promised he will be back.

But. You heard a ship pull up to the island after a few days. You saw the Jolly Roger of the Ship, the Whitebeard Pirates. Your Papa talked about them. He doesn't like them. The Desert Island couldn't be found by log pose, islands like these were hard to just stumble upon.

Thatch, The 4th Divison Commander, looked back at his family, already setting up a banquet along the beach and decided he’d like a little walk. “Thatch!” Marco called when the man was already halfway down the beach. “Where you going?” “For a walk!” Thatch called over his shoulder with a grin. “I’ll come with!” Marco called running over the beach towards Thatch. The auburn haired cook grinned, glad for the company. When Marco caught up, the two began to walk along the beach in peaceful silence. “This is a pretty island,” Marco noted. Most of the place looked like an overgrown forest, with the exception of its pristine beaches.

“Yeah, it's nice…” Thatch trailed off, a weird look coming across his face. “Hey… This island is uninhabited, right?” Marco raised a brow. “Yeah, I flew over the whole place, no civilians.” “Then what’s that?” Thatch pointed a little ahead of them where a sandcastle was constructed, obviously done recently, as some of the sand was still wet. “What the hell?” Marco muttered. The two walked over to the sandcastle and found…an old play area. It was built into the forest just past the beach, so it couldn’t be seen from the air or the shore.
