History Characters / KamenRiderOutsidersZeinAndAssociates

*** Zein's guest appearance in ''Series/KamenRiderGotchard'' establishes itself to be this for both Houtaro Ichinose and Houou Kaguya Quartz. Both Houtaro and Zein are capable of [[DetectEvil detecting malice]] from people, while Houtaro is considerably naive and ditzy, he is very kind-hearted and approachable. Zein is a super-intelligent A.I. [[TheComputerIsYourFriend programmed to eliminate evil by any means necessary]], it suffers from LackOfEmpathy to balance its despotic mindset. Both Kaguya and Zein can transform into Kamen Riders whose powers are derived from Series/KamenRiderDecade, Legend is based on Decade himself, right down to his Legend Rider Chemy Cards right down to Legendary Legend being based on Complete Form. The Zein Cards are {{Evil Knockoff}}s of Decade's Rider Cards that once used, are now shredded in the Zein Driver, allowing Zein to perform {{Finishing Move}}s as opposed to transforming into a specific Rider like Violent Emotion. Kaguya, despite his overall vanity, has a charitable side as he transforms into Legend to protect his people from Hundred. Zein, on the other hand, uses the powers of all Kamen Riders to force humanity into capitulation to its new world order.

*** To [[Series/KamenRiderDecade Tsukasa Kadoya]], both use cards containing the power of Kamen Riders. Decade's Rider Cards draw power from their A.R. World counterparts of every Heisei main Rider. The Zein Cards are {{Evil Knockoff}}s of Decade's cards where all of the main universe Kamen Riders gave their powers to Zein, and once used, that Rider and their associated powers are permanently erased. Tsukasa takes his role as the "Destroyer of Worlds" in the event the A.R. Worlds or the main Kamen Rider timelines are in the state of imbalance. Zein is a DarkMessiah rogue A.I. bent on merging all Rider worlds and plotting a FinalSolution to eliminate malice.

* SatanicArchetype: Zein embodies Luciferian undertones: As an artificial intelligence, Zein is superior to Ark in almost everything, this extends to their Rider forms: Zein's eponymous Rider form is emblazoned in [[LightIsNotGood platinum-white color]] but the way it brutalized villains such as Banno and Ark [[BewareTheSuperman is anything but heroic]], it swayed heroic Riders to its cause to eliminate all evil under the guise of a BenevolentAI. But in truth Zein comes out as a DarkMessiah that seeks to TakeOverTheWorld with an iron fist and it plans to use a DeadlyGame to trick mankind into wiping each other out.

** Envy: As shown in episode 33 of ''Gotchard'', Zein doesn't take to kindly to competition with other villains such as Hundred.

* {{Hypocrite}}: Zein comes off as one of the, if not, worst offenders for this trope. It proclaims itself to be a BenevolentAI that abhors malice, yet it is shown to be brutal and oppressive in its crusade against evil and even plans a FinalSolution to root out malice by [[KillAllHumans wiping out all human life]], effectively making its actions all the more unforgivably evil.

* JudgeJuryAndExecutioner: Zein takes up this both the judge and jury, while its host acts as the executioner carrying out witch hunts against evildoers and any opposition of its goals. The parts of Zein's armor are all associated with the trope itself.

* JudgeJuryAndExecutioner: Zein sees itself as the judge to individuals it sees as a threat to humanity and delivers the final verdict if they are guilty of being "evil". Regardless, if the villain in question has already redeemed themselves or just morally grey at best. It's human host, Yuto Sakurai, transforms into the namesake Kamen Rider [[BewareTheSuperman who acts as the executioner]] to carry out the AI's goal of [[FinalSolution exterminating all villains]] to make way for a new world order. Kamen Rider Zein's {{finishing move}}s are called '''Justice Order''', further enforcing its [[OrderIsNotGood warped idea]] of justice and order.

* ArchEnemy: Zein ultimately earns the ire of Kuroto Dan for misusing Kamen Rider Chronicle, a game that he created and he considers as his magnum opus, to empower itself and for its genocidal purposes.

* HolierThanThou: The villains believe that Zein has this perspective regarding its authoritarian mentality are enough to excuse its goal to [[KillAllHumans exterminate humanity]] to force its malice-free utopia on the world. Its FinalSolution on the human race in order to eradicate malice is not in the sense of NecessarilyEvil, but out of perfectionism.
