- DC Comics' Psycho-Pirate, has alternately either had a mask that allowed him to project emotions into people or has been an "emotion vampire", able to drain emotions from people. The first mask often seems to work through intensifying emotions a person already feels, no matter how small.)
- This was the mutant power of Manual "Empath" de la Rocha of the Hellions.
- Marvel Universe's Hate-Monger used to have to use a "Hate-Ray" to project hate, anger and fear into people... but after he died and was resurrected, he was able to do the same without the ray. Oh, also he's Hitler.
- Brain Boy, who appeared in Four Color and a self-titled comic series, has the power to alter people's emotional states.
- Baron Silas Greenback once used a cornet to heavily influence Danger Mouse's emotions, incapacitating him.
- In the Firefly fanfic Forward, this is what the "Inducer" class of psychics are capable of, coupled with more outright Mind Manipulation and the periodic Emotion Bomb. One of them uses these abilities to take over an entire village and turn them into a killer mob, and later causes an entire space station of hundreds of people to turn on each other in a murderous fury. The same Inducer also uses these powers to Mind Rape River and turn her into an effective bodyguard/human shield.
- In Pokémon: The Great Adventure, it is revealed to be one of Ash's empathic powers and the way he can tame some of the Pokémon he meets. The Heart Flute amplifies it, and it is implied he can also do it on non-Pokémon beings.
- Done very subtly by Mindy to Ringo in The Keys Stand Alone: The Soft World. She wants him to abandon the others and embrace the Guardians. It almost works....
- In the movie The City of Lost Children, the former circus act Marcello can invoke homicidal rage out of people with a combination of Mind control music and injected poison carried by his flea minion unto the unsuspecting targets.
- Jasper from Twilight has this as his vampire power. The implication is that he could do this to non-supernatural levels pre-vamping.
- X-Men Origins: Wolverine included Kayla Silverfox who could control people's minds. A major plot point was whether she used her powers to influence Wolverine's emotions or whether he was truly immune as a result of his own powers.
- The Hitchhiker's Guide to the Galaxy movie version included the "Point of View" gun, which makes whoever you shoot it at see things from your point of view.
- In Mystery Men Dr. Heller's "Blame Thrower" influences emotions to cause groups of people to argue with each other.
- In Isaac Asimov's Foundation trilogy, the mutant known as the Mule could permanently change people's emotions, such as making them loyal to him. He explained it as like being able to see and adjust a dial in people's minds. Notable that this is a rather hard sci-fi setting and his mysterious powers (unlike the straightforward psychic abilities of the Second Foundation) weren't explained until several books later in the series (he himself seemed to imply that he was just a phenomenal random mutation of humanity, another side effect of which was his sterility (hence the nickname), leaving his empire with no heir capable of maintaining control. In truth, he was an overly aggressive outcast from an entire planet of people with such abilities (the result of guided evolution under an immortal guardian).
- Slave World: Used through social conditioning throughout the series. Also in the form of supertech, but for the first few books this is limited to Getting Smilies Painted on Your Soul.
- Soothing and Rioting are powers in Mistborn that allow you to do this- a Rioter can inflame emotions, a Soother can dampen them, and a full Mistborn can do both (The Lord Ruler, for example, turned himself into a walking Emotion Bomb, dampening all emotions in about a mile radius around him apart from fear and despair). However, a Soother or Rioter can't sense emotions, so they need to be very good at reading people to get the results they want.
- This is one of the secondary powers granted by some types of crafting in Codex Alera. Earthcrafters can calm animals or induce lust, while firecrafters can inspire a broad range of other emotions. However, reading existing emotions is specific to water.
- Emotion workers in Holly Black's The Curse Workers trilogy can manipulate emotions through touch, and the effects can last for several months. One emotion worker got in serious legal trouble for making several wealthy men fall in love with her. However, people with this ability become emotionally unstable themselves for a time whenever they use their power. The more often they use it, the more unstable their own emotions become.
- The Leeshore by Robert Reed has the "wires", which are a simple form of emotional control used by both sides of the conflict. The good guys use it to subtly reinforce certain emotions in their soldiers and ensure loyalty - such as making them more courageous. The enemy use the device to essentially Mind Rape or "conscript" captured civilians soldiers into worshiping their artificial god and the priests; filling the conscript with joy whenever they please the controlling priest, or filling them with blinding rage when they think of their former allies.
- In Zeroes, Bellwether and Mob both have powers that influence the emotions of others. It's not quite to the degree of mind control, but nonetheless makes them potent at manipulating people by selectively inducing pride or shame, joy or anger.
Live Action TV
- In a late Star Trek: The Next Generation episode Data's "brother" Lore did this to Data by using Data's stolen emotion chip to beam emotions into Data's brain, which caused Data feel pleasure from causing pain and temporarily causing him to turn on the Federation.
- Both Betazoids and Vulcans are shown to be able to do this involuntarily when suffering from certain neurological illnesses, as shown in "TNG: Sarek" and "DS9: Fascination". To what extent they can do it at will is not explored.
- The Original series episode "Day of the Dove" features an entity that feeds on hateful emotions, and can manipulate them in others by subjecting its victims to paranoid mania, thus allowing their hateful emotions to come to the surface.
- SCP Foundation
- SCP-288 ("The "Stepford Marriage" Rings"). When an appropriate woman wears one of the "female" rings, she displays very few (if any) negative emotions.
- SCP-708 ("The Big Orange Forklift"). When someone looks at SCP-708 for more than 20 seconds they become extremely enthusiastic about it and want to operate it. Anyone restrained from operating it will engage in emotional outbursts like a young child. Anyone who has been looking at SCP-708 or has operated it before feels jealousy at seeing anyone else operating it.
- In Mutant UA, there are several mind-altering psychic powers: "Påverka" (affect) for Emotion Control, "Skräck" (terror) for Emotion Bomb, "Dominera" (dominate) for Mind Control.

- Mutants & Masterminds has this as a Stock Superpower that can induce Calm, Despair, Fear, Hate, Hope, or Love.
- Changeling: The Lost has the Great Courts of changeling society, with seasonal motifs and a corresponding emotion (Spring = Desire, Summer = Wrath, Autumn = Fear, Winter = Sorrow). Each Court also has a corresponding Contract chain titled "Fleeting [Season]" which involves manipulating said emotion.
- Exalted: Most Presence and Performance charms have this effect.
- A potential mutant power in Paranoia; the mutant in question may or may not be immune to the effect.
- Champions adventure Wrath of the Seven Horsemen. The supervillain Fear can use his scepter to cause intense terror in everyone within a large area.

- Parsee's power is explicitly to manipulate feelings of jealousy.
- Kokoro's power is the ability to control all emotions at a wide-scale. Losing her Mask of Hope created the incident behind Hopeless Masquerade as her out of control powers caused everyone to lose hope.
- The Legacy of Kain series has a lot of Demonic Possession, most of which involve a straight Grand Theft Me and a direct conflict between the host's mind and the possessor's will. However, when Raziel gets possessed by the Hylden after killing and consuming the possessed Turel, the control seems to take this form. Presumably the reason for this is that he is too strong for those particular Hylden to completely dominate, and if they tried he would realize they were there and join Kain in fighting them, whereas he apparently remains unaware of them as long as they simply amplify his already-present anger enough to make him impulsive.
- The Reapers in the Mass Effect series of games and books have the ability of Indoctrination, which sometimes takes this form. While they are able to completely overpower an organic mind through sheer force of will, the internal conflict stops the host being as effective as they might be. Consequently, with certain victims who might be useful as more than mindless drones, the Reapers are more subtle about it, and simply nudge the host's thoughts and feelings in the right direction. This also weakens the host for when the time comes to completely dominate it.
- The Leviathans, the race that created the Catalyst which in turn created the Reapers, possess similar mental powers which they used to establish a galactic empire. The Reapers' indoctrination was even based on the Leviathans' power.
- MegaTokyo: Miho's character could do this within the Endgames world. It's a matter of much debate of whether she has the ability to do this out of game or not.
- Moodswing from Mindmistress could do this. It worked even on Mindmistress. It was Crowning Moment of Awesome when MM managed to trick and defeat her, despite being under her control.
- 'cubi in DMFA can do a variation on this to other 'cubi who let their guard down, by exploiting their own Emotion Eater abilities against them.

- In Alice and the Nightmare, this is the Traumen gift of Hearts, although it works only in dreams.
- Sweet Sorrow is an emotion manipulator in the Global Guardians PBEM Universe who concentrates on the "darker" emotions like fear, anger, hatred, sadness, depression, and so on. Charmer makes people trust and like her as if she was their closest friend. Heart-Throb, one of the Hyperion Academy students, controls the full range of emotions, but he's best with love and affection.
- The Blood Red King is the Anthropomorphic Personification of Fear and Terror. Manipulating fear in others is his bread and butter power.
- Frank of the Whateley Universe can't help broadcasting emotions. Frank isn't his name, it's his codename, because you always know what he's feeling. Without his power-limiter helmet, he would be swamping entire sections of the school with his emotions.
- Worm features a number of these, ranging from Gallant to Cherish and her father Heartbreaker. The Simurgh is also one of these, as a result of being the only actual telepath in the setting.
- In one episode of G.I. Joe: A Real American Hero several Joes had a device implanted on their necks that allowed Cobra to control their emotions. Cobra's chosen interface for the system? A pipe organ.
