History Characters / Killzone

* BigBadEnsemble: [[spoiler:With Stahl in ''Shadow Fall''.]]

* FakeNationality: The American accented Sinclair is voiced by British actor David Harewood.

* NonActionBigBad: [[spoiler:As of ''Shadow Fall''. Stahl, who is revealed to be alive, has been operating in the shadows and is the mastermind behind the Black Hand's existence, who is its own financier.]]

* ContrastingSequelAntagonist: To Scolar Visari. Both are rivalling {{Arms Dealer}}s and the CEO of their respective weapon comapanies: Stahl Arms and Visari Corporation, as well as the Autarch of Helghan. Whereas Visari was the first Autarch and the founder of Helghan, who was elected fairly by the majority, Stahl became the last Autarch [[TheUsurper through usurpation]] by killing Orlock and caused Helghan's end via the Terracide. Visari's weapons in his company are all high-tech and futuristic in nature, whereas Stahl's weapons from his company focuses on high fire rate that is reminiscent to 21st-Century weapons. Visari is commanding but also formal and loyal to his men and his cause during the Helghast-Vektan War, while Stahl is arrogant and abrasive who freely throws [[ClusterFBomb curse words all the time]], as well as an OmnicidalManiac, caring little for the Helghast and his own unit of soldiers from his company in an attempt to destroy not only the Vektans but also Earth in a nihilistic act of revenge. Visari is shown to have some form of care to the Helghasts, his own people, albeit in a twisted cause to fight their own war against the Vektans. Stahl is a BoomerangBigot, noting his hatred for the Vektans, but he is also an overt racist against his own race, claiming that the billion people (Helghasts) who died during the Terracide in his home planet are considered weak. While Visari was killed by the main protagonist Rico in ''Killzone 2'', Stahl was killed by Sinclair, one of the main antagonists of ''Shadow Fall''.

** The first and obvious is the Minister of Propaganda himself, Joseph Goebbels. Like Goebbels, Stahl is a fiery, charismatic orator who uses propaganda to inspire his countrymen, and his role as a speaker in Search and Retrieve further reinforces this. His antagonism toward Orlok mirrors Goebbels' tense rivalry with fellow Nazi Herman Göring, [[spoiler: who succeeded Hitler's Head of State and Chancellor offices, like Stahl and Orlock, who became Autarchs after Vissari died.]] [[spoiler: Furthermore, his bankrolling of the Black Hand in ''Shadow Fall'' blatantly references the Nazi guerilla movement ''Operation Werwolf'', which Goebbels created to oppose the Allied occupation of Post-WWII Germany.]]

** Stahl, to some degree, is a serial-numbers filed off take on Ferdinand Porsche, the engineer who designed the Volkswagen and launched Porsche AG (yes, that Porche). Given Porsche's status as an honorary SS officer who had strong relations with everyone's favourite genocidal German, coupled with his job of developing hardware for the Nazi military, such as bombs and war machinery like a prototype heavy tank called the Elefant, it's to ignore that Gurellia Games might have taken inspiration from Porsche when creating Stahl.

* ContrastingSequelMainCharacter: She heavily contrasts to many of the companion characters introduced in previous games. In general, most of them were affiliated with the ISA and are pure-blooded, while Echo is a half-breed and is not affiliated with both sides, despite being an intelligence operative for the Helghast. She's also the first companion character who is related to the antagonist, that being her mother Hera and her late grandfather Scolar.

* ContrastingSequelAntagonist: To her father. Both follow the ideals of a Helghast, but unlike Scolar who would go such lengths to start a war with the ISA, Hera wants to protect her people and is war-averse despite fronting [[spoiler:Stahl's plans of a WMD.]]

* ContrastingSequelMainCharacter: She heavily contrasts to many of the companion characters introduced in previous games. In general, most of them were affiliated with the ISA and are pure-blooded, while Echo is a half-breed and is not affiliated with both sides.
