Raiders

Raiders, known as "illegal Hunters" (違法ハンター逹) in Japan, are illegal Hunters from Mega Man ZX Advent who do not belong to the Hunter's guild. They steal lost technology and deal in illegal merchandise. In the first stage of Ashe's story, she is after a Raider airship to recover a Biometal, but the airship is attacked by Mavericks and it felt in the Oil Field. Later, Grey/Ashe goes to the airship to obtain parts to repair the Train, and when there he/she protected the Raiders from Atlas, who was after the Raiders to give them to Biometal W.

Symbol of Raiders
The symbol of Raiders is very similar to the face of Red which appeared in Megaman X7. It is probable that Red and his group the Red Alert were primogenitors of modern Raiders.
