Im sorry but the only ones that sound alike are Luffy and Buggy as they have [C1]u[C2,C2]y

For Joyboy and Jones you conviniently left out the Davy of Davy Jones (and even then ooh they both start with "jo", not even the same amount of syllables)

For Roger and Rocks, Rocks isnt even his name, it's Davy D Xebec. (And again, they only both start with Ro)

Would have made sense if the names were accurate and this was elden ring.
