The Svengali is a manipulative, controlling mentor that exploits their student for their own gain. They control and exploit their disciple by any means possible, from just plain being a Manipulative Bastard through overt Mind Control to More Than Mind Control, often with a side of Stockholm Syndrome, Lima Syndrome (or both), and Mind Game Ship. Typically acting as The Man Behind the Man, The Svengali is often also The Chessmaster, or at least The Strategist, in terms of PR campaigning. Unlike the Evil Mentor, The Svengali is usually not so much trying to pass on a legacy of evil.
The mentor/protégé relationship may cut both ways, though, since the follower often also serves as The Muse to The Svengali, who may be Hoist by His Own Petard as a result, unable to repeat his success without the student. The Svengali is liable to end up more dependent on the disciple than vice versa. Lima Syndrome is an occupational hazard, often along with some form of Muse Abuse, though The Svengali may not himself be an artist of any kind. Expect additional layers of dysfunction if The Svengali is also a Stage Mom (or Dad), in which case shades of Knight Templar Parent are also likely. The Svengali also tends to pursue success so ruthlessly that bystanders are maimed.
The Svengali is more likely than the Evil Mentor to be Obliviously Evil. Watch out for appearances of "But I did it all for you!" and, conversely "I made you!" (for extra points, add "and I could break you just as easily.").
The Svengali is a frequent, even near-inevitable, cause of Rage Against the Mentor. Since The Svengali's job is usually to provide their ward with worldly success and Ambition Is Evil, What Have I Become? moments (where applicable) tend to turn into What Have You Made Me moments, kind of like I Hate You, Vampire Dad but with fewer fangs. A less malicious version is a Mooching Master, who might take advantage of his student, but he still genuinely cares for him and doesn't actually utilize him as a pawn beyond simple personal gains.
Not to be confused with Svengoolie.
A common use of the term in real life is a mentor or other authority figure who manipulates and grooms their pupil for sex. This is one way, but certainly not the only way this trope can play out.
- The Crane Hermit (Tsuru Sen'nin) in Dragon Ball incites his students to lead a life of crime and murder, which they carry out mainly in a sign of respect for him in the case of Tenshinhan and Chiaotzu; in the end, only his younger brother Mercenary Tao still followed in his treacherous footsteps.
- Tenkei Iwafune is this to Nagare Hisui, the Green King, in K: Return of Kings. He found a dead child at the site of Kagutsu's Damocles Down and witnesses the Slates revive the child by awakening him as the Green King.

Kaiser didn't even show any gratitude towards Saruyama, and when he felt he didn't need him anymore, fired him.
- In the Doctor Who Magazine comics, Jodafra to his niece Destrii, who he acts as a father-figure to but uses as a pawn in his schemes. When he first appears, he looks like a Lovable Rogue, Destrii's only non-abusive parental figure, and possibly the nicest person in an incredibly corrupt and vicious Decadent Court. But as things continue, his true evil nature becomes apparent, and he finally ends up beating her viciously and leaving her for dead after she stops him feeding a group of kidnapped children to an Eldritch Abomination in exchange for powers.

- While originally a Big Good, X-Men founder Professor X has taken a slow but steady descent into one of these since the Dark Age of the '90s. While never attempting to use his students for financial gain (because he doesn't need to, being a member of Marvel's Fiction 500), he has manipulated them seven ways from here to Sunday, ranging from garden-variety emotional manipulation to outright memory repression, all in the name of keeping as many of his students in their X-uniforms as possible.
- Mastermind: Rise of Anarchy: Principal Nedzu turns towards this when he notices that Ochako's Survivor Guilt is driving her to push herself further and further.

- Star Wars: Emperor Palpatine. Though it isn't clear with Darth Maul, he clearly used Dooku's death as part of his plan to turn Anakin to the Dark Side, and then intended to use Anakin's death to turn Luke.

- Vergere in New Jedi Order is this to Jacen. Probably. Sort of. She's so enigmatic that it's hard to figure out what she actually wants, but it's stated (by a Sith, mind you, who may be an Unreliable Narrator) that Vergere was a Sith who was attempting to turn Jacen to the Dark Side, and she does certainly want to mold Jacen into something. Just what that "something" is has fueled fan debates for years.
- Quinn Dexter in The Night's Dawn Trilogy is a particularly dark version of this. Wherever he goes, he is able to effortlessly recruit an enthusiastic following to his depraved religion, often singling one individual out as a protege. However his disciples are utterly disposable to him, and he thinks nothing of murdering or betraying them when it suits him to do so.
- Fagin in Oliver Twist takes in street urchins and teaches them how to become accomplished thieves. He profits greatly from their thefts and simply writes them off when they get caught and executed.
- Erik, the eponymous Phantom from The Phantom of the Opera is this to Christine. Since he actually is a good music teacher he may also qualify as a Broken Pedestal. Due to the similarity of the stories some regard the Phantom as being Svengali with the Serial Numbers Filed Off.
- In Terry Kay's Shadow Song, the deceased Avrum Feldman may be seen as this to the protagonist, "Bobo" Murphy. While he was a friend, the older Avrum is also shown to be a manipulator whose influence over Bobo's relationships stems from his desire to live vicariously through him and see his unfulfilled romantic fantasies play out for someone else.
- In-universe, the supernatural law enforcement rumor mill in the Anita Blake novel Skin Trade has Edward as this to Anita. Or at least that's one of the rumors. "I heard he was more like your Svengali," is the response of one Las Vegas cop to Anita referring to Edward first as her partner and then as her "rabbi" (mentor, one assumes).

- The Master in Doctor Who occasionally takes on "companions" in the same way as the Doctor, but views them solely as pawns in his schemes and usually ends up personally killing them. The most overt examples are Kassia in "The Keeper of Traken", Midge in "Survival", Chang Lee in "Doctor Who: The Movie", Lucy Saxon in his Tenth Doctor appearances, and unknowingly Bill in "World Enough and Time"/"The Doctor Falls". (Lucy reverses things, as she ends up killing him. For a while.)
- Frasier's evil agent, Beebee.
- Game of Thrones: Tywin to Tommen, the new king due to Joffrey's death, and who Tywin clearly intends to mold into a vehicle for Lannister dominance of the Seven Kingdoms, with the side effect that Tommen could probably have become one of Westeros' better kings, whereas Joffrey was already a lost cause before he came under Tywin's influence. Remember that Tywin was Hand of the King to Aerys Targaryen II for 20 years, and despite that king's madness those years are regarded as some of the best in living memory thanks to Tywin's administration.
- In Killjoys, Khlyen trained Dutch from an early age to be an assassin. Though his methods may be despicable, his motives (at least as of the end of season 2) appear to be more ambiguous.

He seemed like a typical Evil Mentor at first, teaching her magic, pushing her to the dark side, and even designing the curse that was central to her master plan... but it was eventually revealed that he needed her to unleash the curse so he would be exiled to Earth, but he also needed Emma to thwart Regina's plans and break the curse, so he could finally be reunited with his son.
- In an episode of the sitcom Seinfeld, entitled "The Wallet", Elaine refers to her psychotherapist boyfriend as a "Svengali" because he wields a powerful mental influence over her. She mispronounces the word as 'svenjolly', causing Jerry and George to mock her.
- Unscrupulous Hero Malcolm Tucker in The Thick of It fits this archetype perfectly, although instead of mentoring a specific person like this, he obsessively controls his entire Party. His Villainous Breakdown in Series 4 even involves him screaming at someone objecting to his plan, because he is doing it all for the Party, and no-one should dare ever question what he would do for the Party.
- Wilfred in Wilfred casts himself as a trusted friend, confidante, and mentor to Ryan but in almost every episode, he seems to be also working some selfish angle. The overall mystery of the show is figuring out what Wilfred is and whether he's actually good for Ryan or not.
- The Beatles went to the Maharishi Mahesh Yogi's note retreat in Rishikesh, India in 1968 at the urging of electronics engineer Alexis Mardas to study Transcendental Meditation. When they got there, Mia Farrow told some of the students the Maharishi made a pass at her by stroking her hair; in her 1997 memoirs, she described an encounter when he tried to put his arms around her in his private meditation cave. The allegations of Pattie Boyd, George Harrison's then-wife, caused life at the retreat to go horribly wrong. At Mardas's urging, John Lennon became convinced when the Maharishi, who said he was celibate, was involved in an affair with one of the young female students. In response, John composed "Sexy Sadie", a Roman à Clef song denouncing the Maharishi's actions, which was included on the second part of The White Album, a.k.a. "The Beatles".
- The Human League's "Don't You Want Me" is a dialogue between a Svengali and his increasingly rebellious protégée.
- Malcolm McLaren cast himself as this to the Sex Pistols, and later to Bow Wow Wow.
- The fans who attended Future Of Wrestling's shows never trusted Fabulous Frank, but there was a steady stream of talented yet gullible babyfaces ready to take on his managerial services. While Frank would, naturally, take credit for any success any of his clients achieved in spite of his lack of help, he was often more interested in using the innocent as distractions, scapegoats, or pawns in his own personal schemes, which ranged from assault to petty larceny.
- Sophia Lopez, Caged Heat's lawyer on Women Of Wrestling's revived third season, finally got the convictions of two members overturned only to then ask newly freed Delta and Loca to commit crimes for her, apparently not realizing they spent the last fourteen years claiming to be innocent because they were serious. So she instead tried to get them to cheat during matches but having lost their trust, Delta and Loca decided to wrestle clean, if still rough by WOW standards, instead. Lopez kept trying to "help" Delta and Loca win the Tag Team Titles, but only because she thought they were still useful for, among other things, helping her entice a wrestler who could actually be controlled.
- Atlas/Frank Fontaine to the player character in BioShock. Interestingly, he seems to at least partly believe his own lies about being a mentor; during the climax, he has the audacity to call you ungrateful and even claims that hes the closest thing to family you have.
- Master Li in Jade Empire, so very much.
- Kreia from Knights of the Old Republic II to the main character. Fridge Horror sets in once you've replayed the game and seen just how much of the relationship between these two characters falls under More Than Mind Control. Depending on the theories you subscribe too, it may have been done all for revenge or for the greater good, but only two things are really certain: firstly, that they seem to actually care for each other in a twisted fashion, and secondly, it worked.
- Darth Vader was this to Starkiller.
- Dōman Ashiya is this in Kuon. He has set out to sacrifice the lives of his disciples (along with that of his own daughter) in his own pursuit of power, through the eponymous forbidden ritual. He had thus set out for the haunted mansion where he would perform the ritual, claiming to be merely investigating it; and waited for them to come find him.
- Harlan Fontaine to Courtney Sheldon in L.A. Noire. Not only does he shamelessly manipulate and use Sheldon for his Evil Plan, but he outright kills him the second he outlives his usefulness.
- Lucan in Magic and Mayhem in hindsight. While presenting himself as your average Eccentric Mentor, he keeps concealing vital information from his own nephew and tricks him into making great sacrifices like his youth for his own ends without so much as giving him a choice.
- The subject of the Quote Source for this page, Ichiryuusai Madarame from Persona 5, is a juggernaut of the art world who maintains his position of prominence by systematically abusing his live-in pupils, plagiarizing their work, and discarding them when they begin to question him. He keeps his only current student, 16-year-old Yusuke Kitagawa, in a state of impoverished semi-starvation while he secretly lives in grandeur, and his Shadow later reveals that he allowed Yusuke's mother, another of his former students, to die from an epileptic seizure so that he could take credit for her masterwork, the Sayuri, which became the painting that launched him to international superstardom.
- Manfred von Karma is this to Miles Edgeworth in Phoenix Wright: Ace Attorney until the end of case 1-4 in the first game. The main reason why he takes in Edgeworth is because he sports one hell of a grudge against Edgeworth's dad, Gregory Edgeworth, a defense attorney who managed to tarnish Manfred's perfect 'all guilty' court record by giving him a penalty. During the DL-6 incident, Karma murdered Gregory in cold blood, and molded his young son into becoming a prosecutor before framing him for a new murder years later, all in the name of petty revenge against the Edgeworth family. However, he gets his comeuppance when Phoenix Wright exposes him as Gregory's killer, and Edgeworth recognizes Karma's demonic scream as the sound that terrorized him so much as a boy, causing the aptly-named Karma to suffer an epic Villainous Breakdown.
- Strongly implied to be Van's relationship with Asch in Tales of the Abyss, especially with All There in the Manual information taken into account. Given that the Rage Against the Mentor starts not long after the beginning of the game, that aspect their relationship is never explored on-screen; however, interviews state that Van kept Asch isolated and uninformed in order to keep him pliable. The Lima Syndrome aspect is implied and twisted up; Van fully believes he "needs" Asch to pull off his plan ignoring the replica with the same powers he himself made that, until the Wham Episode, had Undying Loyalty to him. Despite Asch repeatedly saying he would never work with him, Van is convinced he will.
- There was a Mighty Mouse episode called "Svengali's Cat".
- My Little Pony: Friendship Is Magic has Svengallop, the unironically named manager of pop star Countess Coloratura in "The Mane Attraction." True to the character he was named after, he controls almost every aspect of her life to live in luxury and be a Jerkass to everyone.
- An episode of The Simpsons featured a master criminal hypnotist named Sven Golly, who used his hypnotic abilities to manipulate others for his own gain or amusement.
- The Steven Universe episode "Story for Steven" revealed that Greg's former manager Marty bossed Greg around without much regard for what his personal or artistic concerns were, at the same time undermining his confidence with constant insults and taking 75% of his profits. Atypically, Marty is not just abusive, but very incompetent as a manager, not having the patience or work ethic to promote Greg properly.
- The Thundercats 2011 reboot featured the raccoon character Tookit (get it?), a "kleptovoyant" who made friends with the Thunderkittens. A clear expy of Fagin, Tookit tempted Wilykit and Wilykat, as well as other orphans, into stealing for him in exchange for his "protection."
- In the Season 2 episode of The Venture Bros. titled "Guess Who's Coming to State Dinner?", Col. Bud Manstrong angrily calls Brock Samson "Svengali" when the colonel finds his mother passed out in Samson's lap.
