Personally I think he is. I doubt that anyone gave it to him

What am I supposed to vote, there are two questions that I have seperate answers for..

If he was the first owner, no one gave it to him, he got it himself. If he wasn’t, someone gave it to him

There is a giant SH so it appears there is at least more than one. I imagine the hat has been passed down to those of a shared will

I believe Roger was the first owner indeed, but the data is still insufficient.

Therefore, a team of highly trained monkeys (aka Luffy's family, LOL) has been dispatched to deal with this situation.

Rocks maybe?
