Cynical, manipulative and ruthless, Captain Monasterio leads Monterey’s garrison with an iron fist. He embodies the tyrannical and corrupt power at play. He is the fort’s military leader and also acts as mayor, or Alcalde. He rules over his troops and citizens using fear as leverage. Behind his order-keeping façade, he is pursuing purely personal interests. He wants to get rich, obtain a title and leave the military uniform to get into politics. His ambition is boundless…

One individual seems able to thwart the Captain’s plans : Zorro. Monasterio nurses a total and ferocious hatred towards Zorro, a hatred bordering on obsession.
