Towards the end of João Franco's campaign, breaking the flow of the game's story by choosing to attack Catalina's fleet will prompt his crew and opponent to mock him for being spiteful against her, causing him to be renamed to "Spiteful Franco" and significantly reduce his stats, making the game unwinnable. Upon her defeat, Catalina will then appear on the overworld as a hirable vagabond sailor.

A similar situation occurs when attacking Ezequiel's fleet, causing João to be lambasted for making such a poor decision, renaming him to "Nitwit Franco", and dropping his stats to the same unwinnable level.
