So i saw three vids of three theories so one of them says gold roger was alive bc he was cuffed in seastone even though he doesnt have a fruit second one says luffy is joyboy as he travelled back in time and the last one says shanks is a villain.

Imma connect this.So, gold roger travelled back in time to stop shanks from stealing the one piece and probably luffy is roger's father bc they have the same hat and roger peobably stumbled on some manual for time travel and went to the future (and maybe luffy died that time)
