The Roger Pirates were the crew of the late Pirate King Gol D. Roger and was supposedly the only crew to ever reach Raftel.
This was the crew that traveled around the Grand Line together and the things they did were part of legends.
Ironically, only the captain and the first mate seem to have been remembered while the rest of the crew have apparently faded out of memory, all save those still active like Shanks and Buggy.
The Roger Pirates’s ship, the Oro Jackson, was constructed by the most skilled shipwright of the era, Tom. The ship had a large cannon in the front surrounded by a pair of mermaids. This cannon was powerful enough to destroy an entire ship.
The Roger Pirates jolly roger is the traditional skull in One Piece with a mustache that resembles Gol D. Roger’s mustache.
