I can only think of Trafalgar Law for the moment as the shichibukai that half guy was refering to. Because we saw what Law's power look like two years ago plus if those divers are friends of the "shichibukai" that would explain why they are in diving suits since Law's ship is submarine. That would mean they were hiding the whole time underwater.
