All of NCT, including WayV, are pirates. Each unit has its own ship. There's 127 Crew with Captain Taeyong, Dream Ship with captain Mark (and shipmate Haechan who can't seem to leave him alone about being captain so he's just kind of become his right hand man) and WayV Fighter with captain Kun. 127 Ship is the most friendly bunch of pirates that just explore planets to look at plants and mess around. Dream ship are all young pirates who were inspired by 127 crew to begin life in the great unknown. Mark is a part of the 127 Crew but is betraying them to lead the dream ship. WayV are the most feared pirates in space. They plunder and they take ships and they look really fxcking cool. Obviously, they're all kinda cute idiots too and are actually very merciful when its required.
