Space Pirate Captain Harlock [OVA]

Wikipedia: The series presented a story arc in which a huge black metal sphere strikes Tokyo and ancient Mayan legends appear to be walking the Earth again. The invaders turn out to be the Mazone, a race of plant-based women who explored Earth in the mythic past and are now back to reclaim it. Only Harlock and his mismatched crew are brave and capable enough to face the enemy.
