Power feels good...
For some, that is true in a very literal sense. When a character either gains superpowers (often coupled with Powers as Programs) or becomes more powerful they will feel pleasure sometimes expressed in a similar way to an orgasm. Thus it's often used as means of Getting Crap Past the Radar.
The pleasure this power gives is usually expressed to phrases like "Yes! Yes! Yes!", "I can feel the power surging through my veins", "This feels so good," or similar, often in a very explicit way.
Whatever the case it is made clear that the person is really enjoying the pleasure his/her new powers give. Sometimes a side effect of this is that the person will have an addiction similar to drugs, which makes their "superpowers" similar to a G-Rated Drug. If they experience this with Psycho Serum, the two tropes merge.
This trope is mostly associated with villain characters as they are the more likely to express pleasure when gaining power and using it for hedonistic purposes than heroes. In contrast heroes are more likely expected to dislike their powers.
- In The Big O, Alan Gabriel really enjoys being wired directly into Big Duo.
- The reason the modern Claymores from Claymore are exclusively female is because release of yoki (demonic energy that powers them) is this to men. To be even exacter, male Claymores (produced long ago) experienced the power-up as sexual pleasure and Awakened almost immediately.
- Dragon Ball Z:
- After Piccolo merges with Nail, he spends a good minute just standing there reveling in how awesome he feels. The infamous dubbed version is now known as "Motivational Piccolo".
"Wow... unreal... my gosh...! This is AMAZING! I feel INCREDIBLE~! YES! YES! YES! YES! I can win! I feel great! I! CAN! DO! THIS! AAUUUGH! [beat] Yes! I'm home! I'm alive! This is all a miracle! I'M AWAKE! I'M WIDE AWAKE!!"
- The Dragon Ball Kai version, while less memetic, has just as much ham.
"This strength...this unimaginable STRENGTH! If I had known that merging with another being could result in this kind of power, I would have sought it out YEARS ago! I am INVINCIBLE! No-one can stop me now!"
- After Piccolo merges with Nail, he spends a good minute just standing there reveling in how awesome he feels. The infamous dubbed version is now known as "Motivational Piccolo".
- Pilots in Genesis of Aquarion react downright orgasmically when three Vectors combine into the eponymous Aquarion. The moaning and facial expressions are probably just there for Fanservice.
- In Jo Jos Bizarre Adventure Stardust Crusaders, DIO explicitly compares rejuvenating himself with Joseph's blood to a high, while tearing at his own flesh with his fingernails to show off his enhanced regeneration.
- Inverted in Princess Tutu. Rue feels pain when she transforms.
- In Puella Magi Kazumi Magica, Airi after becoming Yuuri says "Haha this is great! these powers are the best." All of this while licking her lips and looking very very pleased in a suggestive way. Kazumi also has a moment of this in chapter 1 in her first battle.
- S Cryed: While Kazuma may have a heroic motivation for gaining the power (fighting a Knight Templar organization) but there's no denying the look on his face when using his Alter. Particularly once he gets his first Alter upgrade.
"More power! And more! SHINE BRIGHTER!!"
- Masane in Witchblade enjoyed her combat form... very much, until she both got the hang of it and realized how taxing the transformation is. One of the first times, she briefly crouches high on the wall, murmurs "Amazing." and licks her lips, looking at incoming rocket swarm, before jumping. There's a lot of such scenes.
- The rare DCU Psycho Serum Aramilla gives the user an incredible rush. In Robin when Tim is slipped some he notes how fun it feels and he knows he's become dangerously detached from the violence he's doling out. His feeble attempts to control his attitude are all for naught until he actually kills someone. They get better of course since his performing CPR slips them the drug.
- The Ultimate version of She-Hulk definitely experiences this in her first transformation◊
- Lilith already had this to some degree in Borderlands, made more explicit in Borderlands 2 ("This stuff is the tits!"). In Fractured, a Mass Effect/Star Wars/Borderlands crossover, she goes off the deep end after having a change in alignment. It's not just her powers, either—an actual Psycho Serum is also involved.
- In My Huntsman Academia, Nora can get one when she's particularly charged up with electricity, easily pounding an Ursa Major's torso into paste before declaring that she'll run out and kill every single Grimm in the Emerald Forest.
Nora: [at the top of her lungs] STOP, WHATDYAMEAN STOP PARTNER?! I FEEL LIKE I NEVER HAVE TO STOP AGAIN! I BET I COULD RUN THROUGH THIS ENTIRE FOREST AND KILL EVERYSINGLEGRIMMTHATCOULDPOSSIBLYLIVEHEREWITHJUSTMYLITTLEHAMMER! I DON'T NEED TO STOP! I CAN'T BE STOPPED! I'LL GO EVERYWHERE AND KILL EVERY GRIMM EVER EVEN THE MOST TERRIFYING ONES BECAUSEIJUSTCAN'TBESTOPPEDNOTBYANYONEORANYTHING!
- In Raindancer, Izuku's Quirk, "Liquid Body", allows him to completely turn his body into water. Because of this, he's literally in his element when he's raining, causing him to forgo an umbrella to savor the euphoric feeling of being surrounded by so much water. He also gets a similar effect when he's basking in moonlight, particularly when the full moon is out. During this time, he can act as though he's loopy, on an adrenaline high, or even drunk. Both conditions increase the potency of his already devastating control over water, warning his friends to yank him out of it if he starts acting weird.
- With Strings Attached: In the Second Movement, when the other three get magic, it makes them so high that it takes them weeks to notice that Paul didn't get any.
- While all of the four experienced Power Highs in With Strings Attached, by The Keys Stand Alone only Paul and Ringo still do in significant ways. Paul gets high off the background noise of his magic, which is like a triumphant thundering symphony, and uses it both to pass the time at night (he hardly sleeps) and to calm himself down when he's getting agitated, which proves useful on numerous occasions. He is not, however, addicted to it. Ringo, on the other hand, is so thoroughly addicted to his mindsight that he goes into withdrawal when he's blocked and thinks he'll kill himself if he has to go back to Earth without it again. Paul also discovers that absorbing energy gives him a rush as welland, when he was hit by two lightning bolts in rapid succession, he also got drunk and had an orgasm.
- In The Taste Of Your Magic, Bellatrix Lestrange describes breastfeeding Harry Potter as addictive, since doing so allows Bellatrix to increase her magical power. She even contemplates vanishing the milk in Harry's stomach just so she could continuously feed him, but figures that even if it did work, it would trap her in an eternal high until she wasted away.
- In Disney's Aladdin, Jafar wishes to become a genie. His wish is fulfilled and while gaining "phenomenal cosmic powers" he proclaims "The power, the absolute power! The universe is mine to command, to control!". His enjoyment falls short thanks to Aladdin's Batman Gambit. He forgot about the "itty bitty living space" that comes with genie powers.
- When Tony Stark inserts the new element into his arc-reactor in Iron Man 2, he gets a very sudden high.
Tastes like... Coconut... and METAL! Oh, YEAH!
- In the previous movie, Obadiah Stane pilots the Iron Monger suit in a last-ditch effort to get rid of Tony. He later admits that he's really enjoying the power of the suit.
- Pirates of the Caribbean: At World's End: When Tia Dalma is released from her human form and regains her godly powers by becoming Calypso, she makes a familiar expression that makes her enjoyment very evident.
- Spider-Man 3: When Peter gets the symbiote he says that "I feel wow... this feels good!"
- Star Wars
Palpatine/Darth Sidious: '''POWEERR!!! UUUUUNLIMITEEEED POOOOOWEEEEEEERRRR!!!!'''.
- Not to mention that he seems to have undergone an orgasm after this.
- An inversion is evidenced in X-Men.
Rogue: "Does it hurt when [your claws] come out?"
Wolverine: "Every time."
- In Buffy the Vampire Slayer, when Willow starts to OD on witchcraft it's explicitly analogized to a drug high. She ends up in Rehab because of this.
- Spoofed in The Fresh Prince of Bel-Air, where Carlton has this reaction... to Will handing over his little black book. Complete with a golden glow suffusing his body.
- The Shannara Chronicles: Using magic affects everyone differently. When Eretria gets her first taste, she says it makes her "feel invincible."
- Everworld: Senna claims using magic "...filled me up, rushed through me, the sensation of power more erotic than any fantasy, more exciting. The power, I loved it so, it filled me and fulfilled me. It was mind, it was body, it was sex and money and power and revenge and triumph all rolled into one."
- Journey to Chaos: Breathing in the magical mist known as "Fog" will cause a rush of power directly to the user's soul. It's described as a "heady experience" and people get addicted to it. Those that capitalize on this are analogous to drug dealers.
- Labyrinths of Echo had the Order of the Holey Chalice, where power was acquired by drinking from bottomless cups. The protagonist given a taste of this felt literally power-drunk, which an ex-adept confirmed to be the normal effect — and noted that it's important to discern the real power boost from illusions of power. The Order's acolytes were given the taste of power from their masters' cups now and then and became full members after they learned to keep the liquid from spilling on their own. As a result, it was one of the magical traditions with very, very motivated apprentices, but no training on self-discipline at all.
- When one of their Minor Magisters, already well-adapted to this, stole the reserve of power from a lot of huge aquariums. He remembers very little from the next few years, but managed to earn the monicker "Mad Fishmonger", among the mages half of whom were obviously batshit insane and the rest just dangerously obsessed. In the city which (according to himself, much later) everyone of right mind left in haste long ago on account of the civil war between these overpowered nutcases.
- Once was used in a mental attack against Max, after which, instead of hunting an enemy, he shredded annoying, but harmless phantasms in happy bloodthirst — and since he didn't actually receive any extra power, ended up so weak and vulnerable that his boss could neither leave nor use strong magic around him before arranging an external protection.
- The Wheel of Time: People channeling the One Power gain such acute senses and feel so much more alive that they have to discipline themselves to let go of the Power afterwards. It's so addictive that most channelers who lose the ability to channel die of despair within a year or two. The True Power, the Power supplied by the Dark One to his favoured minions, is even more addictive.
- The Dresden Files Fool Moon: the FBI agents that are using the wolf belts seem progressively less stable as the story continues, until at the end they're little more than psychopaths looking for their next high. When Harry uses the belt he grabbed earlier, he's immediately lost to the power and sensation, and the narration reflect that he's enjoying it far too much...until he almost kills Susan, and tears the belt from his body, describing it as pulling off a layer of skin, and leaving him weak, tired, and with the nagging desire to immediately use it again.
- In Dawn of a New Age: Oldport Blues, after Dark Dragon uses his Elemental Absorption to absorb Luna's lightning form into his body, the rush of power gives him an almost orgasmic high. He gushes about how good it feels, how he feels pumped up and overflowing with power, all the while making his usual dirty jokes.
- Amber Diceless Role-Playing. In the section on the character Merlin, it says that the magical powers possessed by Amberites make the user feel so good that they can become addictive.
- In Forgotten Realms, elven magic users in the area of raising mythal (city-scale spell field) had a peculiar reaction: spontaneously levitate and space out. Elminster in Myth Drannor had a scene when one elven gardener found his noble lady and her handmaiden floating naked over the basin, staring into nowhere and "moaning a chant." He had no options but to shake his head and conclude that "pleasure spells were certainly becoming powerful things these days." The tales spread, and much later some elven wizards (including one Wizard Guild's dean in Raven Bluff) became mythal proponents just because they heard colourful descriptions of this effect.
- The more Anarchy stacks Gaige gets in Borderlands 2, the more she tends to invoke this. This includes yelling, "I'm getting a god complex and I LIKE IT!" and it all goes downhill from there.
- In Overwatch, all of the heroes have an "I am unstoppable!" line for when Ana nanoboosts them. Especially noticeable with the tanks (except Roadhog).
- In the Persona franchise, the heroes of 3, 4, and 5 are all shown enjoying a taste of their new power when they first summon their Persona. This carried over to the anime adaptations of 3 and 4. Interestingly, in Persona Q: Shadow of the Labyrinth, Yosuke can sometimes be heard yelling "Give me power!" in a demanding voice when summoning his own Persona. This seems to mostly just be for flavor, as in none of these cases do the Power High aspects play a role in the plot or character development.
- It is possible to get addicted to power in Persona 5: at the end of the game, Yaldabaoth offers to give the Phantom Thieves control of the Metaverse (as they are currently trying to destroy it to keep Yaldabaoth from chaining down humanity's free will). It's possible to accept, with the notion that destroying the Metaverse would destroy their Personas, which drove them through their story, being explicitly mentioned.
- In Portal 2, Wheatley, when placed into a position of complete power over Aperture, immediately begins to show symptoms of a power high, commenting on how small and insignificant Chell is. Unfortunately, this ultimately leads to his FaceHeel Turn.
Wheatley Do you have any idea how good this feels?
- Juri from Super Street Fighter IV after gaining ki based powers from the Feng Shui engine she proclaims: "Mmm...I like it. I can feel waves of ki energy surging through my whole body" in a very suggestive way. This can be seen here.
- In Ultimate Spider-Man, when Venom gains absolute control of his symbiotic suit he screams " Yes! Yes! Yes! now I have TOTAL absolute control!" See it in this video.
- Starting in Resident Evil 4, anyone that's conscious enough to exert control over their viral transformation really, really likes it. This includes Salazar and Sattler from the fourth game, Irving and Wesker from the fifth game, and Simmons from the sixth game. Resident Evil 7 is an aversion: while they profess to greatly enjoy their transformations, Jack and Marguerite are shown to be horrified by what they've become and what they've done. Lucas, on the other hand, is a psychopath who is only pretending to be infected, so his "power high" is entirely fabricated.
- Wesker really liked it as far back as Resident Evil Code: Veronica (dramatically announcing "Sure I'm not human anymore, but just look at the power I've gained!" as he holds out his arms in something between a T-pose and Milking the Giant Cow and spins around, as well as all the maniacal laughter) and even the Rebirth scenes in Resident Evil: The Umbrella Chronicles ("Time to take this virus out for a test drive" *kills every zombie in sight* "What amazing power!")
- Girl Genius, when the new Heterodyne is subjected to the effect of Dyne water plus electroshock for the first time and feels (and looks) godlike. Later the Castle implies it's a normal reaction:
- El Goonish Shive: Exploited. Everyone reacts to large amounts of magical power differently; some are pained by it, some get a burst of euphoria. An immortal found someone who became extremely suggestible when exposed to magic, so he pumped him with as much magic as possible, then started giving him "suggestions," which basically turned him into a mindless slave. This allowed the immortal to get around the fact that immortals are only allowed to empower and guide mortals.
- In Ava's Demon, the titular Ava drinks a potion crafted by her demon to give her a power boost when she needs it. She is delighted to find that this trope is in place and horrified to realize that it and the accompanying transformation are permanent.
- In The Lazer Collection:
Dr. Octogonapus: Feel the power, Randal! Let it seep up your thighs and penetrate your body! Let it penetrate you, Randal!
Randal: It feels good!
Dr. Octogonapus: Now release! Let it build up and release!
Randal: Hnnn... BLAAAAH!!
- In Harvey Birdman, Attorney at Law, Harvey, who gets his power from sunlight, discovers that suntan lotion can provide the same effect. He quickly becomes addicted to the rush and starts spending all his money on lotion, until his friends are forced to stage an intervention.
- She-Hulk in the old '90s The Incredible Hulk cartoon seems to really like transforming.
- In The Mask animated series, a gypsy woman steals the power of the mask and screams "yes yes yes!" while she does.
- In Steven Universe, this trope is one of the features of gem fusion. Fusions are a good deal more powerful than the sum of their parts, and forming one feels good. True to the nature of the trope, though, this is not without its cons. Sugilite is so caught up in her own raw power that she refuses to unfuse back into Amethyst and Garnet. Pearl so deeply enjoys the strength and confidence she experiences as Sardonyx that she starts pulling off a series of one-gem False Flag Operations in secret, just to create an excuse to fuse with Garnet again. When Jasper takes control of her and Lapis' fusion Malachite, it's clear she's having the time of her life with the sheer power she now possesses. When she reappears later, she's completely obsessed with fusing with Lapis again.
- In the Teen Titans episode "Overdrive", Cyborg installs the Maximum-7 processor chip into his systems and he soon goes "BOOYAH!" as he feels the increase in power.
