Adaptational Weakling

In an original work like a book or graphic novel, you have a powerful character. Maybe they are The Ace. Or they are a god, that demonstrates omnipotence. You respect their power.

But where's the fun in that when you adapt said work to a movie, television show, or anime? Where are the stakes when your character can beat down their opponents with ease?

The Adaptational Weakling, the opposite of the Adaptational Badass, can still be strong, just not as strong as their original counterpart. If a character is still supposed to be badass but is shown easily defeated in an adaptation, they might be victim of the The Worf Effect. Chickification is often a subtrope, when a girl who was previously a capable combatant becomes kidnapping bait. Sometimes the creator's intention is to raise the stakes. Other times, it's to further character development or aim for a change in tone.

Note: on TV tropes, this is referred to as Adaptational Wimp, but going with Weakling since it's a close-enough synonym and we don't have to debate on the name.

Anime and Manga

 * Sailor Moon
 * It's revealed that the Silver Crystal users, in general, are this in the 1990s anime. The users can do anything with the Silver Crystal in the manga and suffer little to no consequence; in fact, Sailor Moon was even able to revive the world during the Infinity Arc after Sailor Saturn had to destroy it to stop Pharaoh 90 and Mistress 9. In the anime, the crystal can grant the users' greatest wish if used at full power, but at the price of their life. Queen Serenity, Sailor Moon, and Chibi-Usa have each canonically died at least once while using this ultimate power. Sailor Moon and Chibi-Usa revived due to extraordinary circumstances, but sadly Queen Serenity did not.
 * Tuxedo Kamen gets more to do in the manga, owing to receiving a special attack that allows him to even the odds. For most of the 90's anime, he's stuck with the roses, though they still are pretty dangerous to the target. Just ask Queen Beryl, who received a killing blow with a rose to the heart.

Film

 * In the How to Train Your Dragon novels, Snotface Snotlout is The Ace and top of the Hooligans' class, as well as Gobber's favorite student. He's a big jerk and a bully to his cousin Hiccup as a result, who . During How to Train Your Dragon's three movies, in contrast, Snotlout is probably the worst student of the Dragon Trainers excluding Hiccup before the latter starts excelling; he's full of braggadocio but can't aim, as a laughing Stormfly noted when he missed hitting her with a mace, and spends more time flirting with the ladies than focused on fighting. Even the twins are relatively better, as it's shown they figured out Stormfly's blind spot and hid it in while arguing. The first TV series showed that he does make up for it with hand-to-hand combat, which he uses to save Hiccup.
 * Lampshaded in The Lego Batman Movie many times.
 * Commissioner Gordon is shown to have earned his stripes in the comics, using Batman as an ally while fighting corruption with everything he has. He even stayed in Gotham during the No Man's Land arc to protect the civilians who could not evacuate. Here, his default solution is either pressing the button for the Bat-Signal or having Chief O'Hara dial the Bat-phone. With that said, when Batman is unavailable, he refuses to negotiate with Joker when the latter demands for the mayor to surrender and sets up a perimeter around the water plants where Joker has set up bombs to destroy Gotham city. He protests when the mayor prepares to surrender herself to the Joker. Fortunately, turns out the mayor was Batman in disguise and the real mayor is safely in hiding.
 * Happens a lot with Batman's usual Rogues Gallery. The heavy-hitters like Bane, Poison Ivy and Harley Quinn have a comic history of incapacitating Batman if not landing heavy blows on him. In the opening where Batman confronts them, he curbstomps them in seconds while singing a song about how awesome he is, with the Batmobile and 'Puter's help. Joker is befuddled and asks, "How is he beating all of you again?!" In fact, this realization motivates Joker to . Quite ironically, the Rogues prove to be more useful when they.

Literature

 * A possible interpretation of the story "Cruel Sisters", a take on the Child Ballad "The Cruel Sister". In the original ballad, Helen killed her younger sister with barely any effort and refused to pull her out before the currents took the princess. Patricia C. Wrede's version has Margaret, the narrator and middle sister, note that while the eldest sister Anne was certainly strong enough to push youngest sister Eleanor in the river, she doubts that it happened. For one, the harp that makes the accusation was made from Eleanor's body, and Eleanor was a liar in life. And for another, Eleanor assumed that they were fighting over a "true bonny" William, where William played with both girls' feelings. Anne also has a habit of not admitting her guilt or innocence to any crime, bearing her punishments with stoicism.

Live-Action TV

 * The Sandman
 * In the comic book The Sandman, Lord Morpheus is pretty powerful even after spending seventy years in captivity. He remakes his Dream palace with a simple gesture, and only needs a few days of bed-rest. In the show, Dream doesn't even get that owing to a hundred years in captivity; he can barely move a few pieces of rubble, and refuses to rest or get food. He has to sacrifice Cain and Abel's gargoyle Gregory to receive enough power to summon the Fates and receive answers about his tools' location.
 * Hector and Lyta Hall were superheroes in the Golden Age as The Sandman and Fury respectively. When Dream invades Jed's mind, where a dead Hector and living Lyta are imprisoned, Hector attacks what he thinks is the King of Nightmares and at least tries to fend off what he thinks is a supervillain. It does nothing to Dream, who bursts out laughing on hearing that Hector calls himself the Sandman, but it's implied he was formidable in life, and confirmed in the Justice Society of America series when Hector and Lyta continue their superhero work. In fact, it's implied that Lyta's hero moniker and previously rebooted backstory as Wonder Woman and Steve Trevor's daughter was what . The series, to avoid having to explain thirty years' worth of comic continuity, makes them both ordinary architects and Hector died in a random accident. What's more, Hector is more accepting if saddened when Dream breaks it to him gently that.
 * Comic-book Gilbert realized that he couldn't take on the Corinthian after recognizing him, but realized that the latter had . Here, Gilbert doesn't have that opportunity; Corinthian recognizes him at the Empire State Hotel when the latter is helping Rose search for Jed, and is willing to kill . Realizing he has no choice,

Theatre

 * The original film of Beetlejuice had the dead couple Adam and Barbara quickly learn about possession and try it for themselves before soliciting Beetlejuice's help. In the stage play, they are worse at it, so Beetlejuice tries to convince Lydia to summon him instead to ruin her father's party. He also possesses Adam and Barbara to demonstrate his powers, something that didn't happen in the film. Lydia has to interfere by pushing him off the roof-- "What? He's already dead"-- and convince the more trustworthy dead couple to do some possession instead.
 * Holy Musical Batman
 * Even though the musical shows that Batman is willing to use lethal force on civilians and villains alike, he doesn't fare well against Superman. In the comics, Batman has many failsafes prepared against Superman, including a Kryptonite ring and even has Carrie in The Dark Knight Returns hit Kal-El with a tank. When the president orders Superman to stop Batman from taking down Sweet Tooth, since Sweet Tooth has threatened to poison all of Gotham while holding Robin hostage if Batman interferes, Superman admits it will be a great pleasure to beat up the "butthead". He proceeds to curb-stomp Batman, who only wins by bringing out his trump card: Kryptonite.
 * Superman himself is fairly powerful, but not respected. He resents Gotham for thinking he's upstaging Batman, and Batman for constantly ghosting him. While he does bring out his time-traveling power, he tells the audience that was a one-time thing.

Video Games

 * Victor Zsasz in the Batman Arkhamverse game starting with Arkham Asylum. He's still a serial killer like the comics, but he's a lot easier to beat and take down, as opposed to the comics where he could take quite a beating and was a serious threat to Batman. By contrast, he's generally limited to encounters where a well timed batarang to the head can render him harmless.
 * The Clue Finders generally has their founder and leader Joni as the tough one. She has a habit of being a Fearless Fool that rushes into situations without thinking, and doing most of the physical challenges. In the sixth grade game, Joni enforces this while offering herself as a hostage for the Anti-Villain plant queen in the third act. Joni admits that normally she would be the one going out to solve the problem, but as leader it's her responsibility to protect her friends, and she trusts them to carry out the task of . She takes.

Western Animation

 * In the Bunnicula book series, Howard and Chester may have had opposing views on if Bunnicula was evil or not, but they were tough enough to try and either harm Bunnicula (Chester) or save him (Howard). The Bunnicula cartoon turned Howard into a bumbling but well-meaning dog that if anything would solve magical problems by accident, while Chester's Nervous Wreck personality would sometimes cause them.
 * The main character of Superman: The Animated Series (and the DCAU as a whole by extension) compared to the comics. He's still super, but not the crazy levels the character often reaches in his comics. Unlike the comics, these powers would remain consistent throughout the series -- flight, Super Strength, X-ray vision, and heat vision-- complete in the Batman Beyond when Terry has to outfly.
