Contrasting Sequel Antagonists that appeared in the
Killzone franchise, from the main series to its spin-offs.
- Mael Radec from Killzone 2 heavily contrasts to Stuart Adams, one of the villains in Killzone. Both have similar views towards Scolar Visari and are also the enemies of the protagonists, but their goals and intentions are different. Adams is an ISA traitor who sees Visari as an inspiration to betray his own allies and is responsible for shutting down the Orbital Defenses with Dwight Stratson, allowing the Helghast Army to launch an attack. Radec is a born Helghast, who is The Dragon to Visari, serving as his personal second-in-command and is a more personal antagonist to Rico, being the known killer of Jan Templar. Adams is the General of the ISA, while Radec is the Colonel of the Helghast Military. Adams rarely uses combat but his gun against the protagonists, while Radec is a full-blown Combat Pragmatist and Colonel Badass, who is adept in firearms, knives and actual close-quarters combat. Adams is a Smug Snake who openly gloated into siding with the Helghast, revealing to be a Dirty Coward at the end as he went through a massive Villainous Breakdown after he failed to kill Templar, before dying from a very unceremonious death at the hands of Templar. Radec is a combat-hardened, honourable Helghast who never backs away on combat, successfully killing Templar single-handedly before squaring off against Rico in a one-on-one fight inside the Visari Palace, before Radec killed himself at the end after his defeat as a sign of honour. They are also killed by the different main protagonists, with Adams from Templar and Radec from Rico.
- Jorhan Stahl from Killzone 3 and Shadow Fall serves as this to Scolar Visari, the main antagonist of Killzone and Killzone 2. Both are rivalling Arms Dealers 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 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 curse words all the time, as well as an Omnicidal Maniac, 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 Boomerang Bigot, 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.
- Thomas Sinclair, one of the main antagonists in Shadow Fall, is this to Alex Grey, one of the main antagonists in Mercenary. Both serve as part of the Big Bad Ensemble, are racists towards Helghast and are high-ranking officials of the ISA, but Grey was the Admiral of the ISA Navy, while Sinclair served as the Director of the Shadow Marshals and now the director of the Vektan Security Agency, the espionage arm of the ISA. While both are born as Vektans, Grey is a Caucasian, pale-skinned, 46-year-old woman, while Sinclair is a dark-skinned, 51-year-old man. Both share the same racist ideology towards the Helghast and are willing to exterminate the other race but for different reasons. Grey is a Well-Intentioned Extremist wanting to use Kratek's bioweapon to ensure peace to Vekta at the cost of the innocents on the other side. Sinclair is Grey's polar opposite, who is a Not-So-Well-Intentioned Extremist and a General Ripper, willing to kill the remaining living Helghast on the other side of the Wall out of his paranoid racist views towards them, regardless of the ensuing collateral damage to the Vektans. Both act as former allies to the main protagonists. Grey is only an ally to the protagonist, Arran Danner, with no relation to him, whereas Sinclair also served as a mentor and a father figure to Lucas Kellan before killing him at the end. While Grey failed to kill Danner, Sinclair is a Hero Killer who murdered Kellan for attempting to stop the reignition of the Helghast-Vektan War and for siding with Echo.
- Vladko Tyran from Killzone: Shadow Fall is this to Vyktor Kratek from Killzone: Mercenary. Both are Helghast zealots who have an equal, seething hatred towards the Vektans, are Ax-Crazy and are also The Dragons to the Big Bad. Kratek is a sadistic Colonel of the Helghast Military who is the subordinate of Metracnote During Liberation, although he becomes the Dragon Their Feet and the Big Bad in Mercenary during the invasion of Diortem, as well as a Mad Doctor who intents to use his bioweapon and kidnap Justus, the proverbial plasmid trigger, to wipe out the Vektans in an act of genocide. Tyran is the second-in-command to Stahl, where he is a zealot Blood Knight and the leader of the Black Hand, who is more so intent on causing chaos and destruction in Vekta than outright genocide, heavily contrasting to Kratek's goals, in an attempt to restart the war between the Helghast and Vektans. Kratek is a 40-year-old man dressed prim and proper with a gas mask on his head, as well as a cape. Tyran is a unkempt 30-year-old man, dressed in the standard Black Hand insurgent gear including a grey robe and infiltrator projectors, as well as having an unknown piece of plastic material that serves as his "cape".
Spin-off series
- The Phantom Talon Corp. in Killzone: Mercenary are this to the Helghast Military in the previous Killzone games. The Helghast Military is the military branch of the Helghast Empire, who oftentimes incite wars against the Vektans in the name of the Helghast banner for their own cause. The Phantom Talon Corp. is a mercenary organisation, with its members being seasoned mercenaries hailing from former military organisations, and have no actual allegiance to both sides of the war. Whereas the Helghast Military fight their wars for the cause of the Helghan and Visari, the Phantom Talon Corp's members are a Wild Card and are politically apathetic to the conflict, fighting on whatever side they are in and only care more for the money and paycheck than anything else. Their commanders, Anders Benoit and Armin Metrac, one of the Helghast commanders and the General of the Helghast Military, also embody this contrast. General Metrac is the General of the Helghast Military during the invasion of southern Vekta, whereas Benoit is the commander of the Phantom Talon Corp. hailing from Earth. General Metrac is a ruthless sociopath who is openly sadistic and brutal, causing carnage for the fun of it, especially towards the ISA, in his twisted Helghast morals. Benoit is a ruthless, greedy schemer, serving as a Wild Card where he has no affiliation to both sides (Helghast or ISA) and is a high-ranking money-driven mercenary commander, only using the war for monetary gains and purposes regardless of casualties, while "allying" with them to get what he wants in the intent of backstabbing them at the end. Both of them have different plans: Metrac planned to murder the rest of the Vektans and conquer the south of Vekta, including Diortem, while Benoit actively wants to kick the Helghast out of Diortem, before soon betraying Danner during the attack on the refinery and initiate his own plan of finding the bioweapon and the trigger Justus, so that he can sell both to the black market. Benoit's also a boss in Mercenary and is comparably closely similar to Metrac, being adept in combat and also lead a group of men on their side. Metrac is the Climax Boss of Liberation, while Benoit is the Final Boss of Mercenary. Both use heavy weaponry and are long-range attackers who attack from a distance, as Metrac uses a Frankenstein heavy machine gun/grenade launcher, whereas Benoit uses a VC39 Accelerator Rifle as his signature primary weapon, as well as an energy shield in ground combat.
- Alex Grey from Killzone: Mercenary serves as a contrast to Dwight Stratson from Killzone: Liberation. Both serve as high-ranking officials of the ISA and are both extremists for different reasons. Stratson was an ISA General who led his unit in Southern Vekta before revealing to be a traitor to the Helghast, claiming that by allowing the Helghast fleet to attack ISA and Vektans within Vekta (whom he proudly calls them as "soft and weak" despite being one), where he is also openly Turncoating to the Helghast by taking Metrac's position as the leader of his forces after his death, before proceeding to murdering the rest of ISA generals and attempt to defeat Templar for one last time. Grey is the Admiral of the ISA Navy who led her unit to halt the Helghast invasion of Diortem and is the opposite to Stratson's General Ripper personality, and she is more openly willing to commit morally ambiguous actions to win the war against the Helghast, including her attempt to commit mass-genocide with a bioweapon as well as kidnapping a child for the virus' trigger to wipe out the other race completely, all for her goal of ensuring peace on the Vektans. While Stratson actively helps the Helghast to successfully win their brutal cause, Grey is openly enemies with the Helghast and hires the Phantom Talon Corp., a mercenary organisation, for extra firepower, in order to win the tide of the war to the Vektans against them.
