* BigBadEnsemble: In the 2016 anime, there are three in total including Kaoru Furushou, Thea Kreutzer and the Musashi Crew, [[spoiler:albeit they are all brainwashed pawns to the Totalitarian Disease, who serves as the real BigBad]]. Kaoru Furushou served as the main catalyst for [[spoiler:Harekaze's exile in the first half of the anime]]. Thea Kreutzer and the brainwashed Graf Spee crew (sans Wilhelmina) serve as an obstacle to the Harekaze, [[spoiler:who wanted to target Wilhelmina and brainwash her]]. The infected Musashi Crew, on the other hand, serve as the final threat, who attempt [[spoiler:to spread the Totalitarian Virus to not just other ships, but to also the Uraga channel close to the Philippines, as well]].

** The Totalitarian Virus, aka [=RAtT=] Virus, is a bio-engineered mind-controlling HatePlague that seeks to prey upon the crew of various ships unfortunate enough to be on its ravaging path through rats as its vectors. [[spoiler:It just happens that the said virus is responsible for the death of its creators, the mass-infections of Sarushima, Graf Spee (sans Wilhelmina) and the Musashi crew (sans Moeka).]]

* On a more ContrastingSequelAntagonist route, the Pirate Leader in the movie is a violent, merciless leader of his Pirate crew, who has plans to capture a decommissioned seafort (at least that's what it was purported) by using [[spoiler:[[UnwittingPawn Susan Reyes]], so that he would target countless maritime cities in Japan with it for his bloodlust.]]

* ArsonMurderAndJaywalking: When Akeno asks for a damage report during the first episode, the Artillery and Engineering departments report something non-trivial, while the galley crew report that their rice cooker has suffered denting. In episode eleven, Akeno checks for combat readiness; the artillery crew are ready and awaiting targeting orders, and the engineering crew have prepared the engines, waiting for Akeno to issue a speed. The Galley remarks that they've prepared rice balls.
