** Eric Cartman in turn is this to Heidi. Both have their {{Jerkass}} moments while also having potential of becoming awful, with Heidi becoming an obese bigot like Cartman in the back half of season 21. However Heidi is at least capable of recognizing how awful she became before deciding to genuinely growth and change to become a better person earning herself a second chance at happiness. Cartman on the other hand never learns his lessons, continues to blame his faults on others, and progressively becomes worse off until he becomes a lonely, miserable, homeless, and deemed BeyondRedemption becoming the type of person Heidi could be if she never learned to take responsibility for herself.

* ''WesternAnimation/BatmanTheAnimatedSeries'':
** This version of the ClockKing, Temple Fugate, shadows Batman's CrazyPrepared tendencies.
** The rare heroic version in [[BadCopIncompetentCop Harvey Bullock]]. He does what Batman does as he bends (read: breaks) the law quite regularly to get results. Also, much like Batman and his seemingly harmless alter-ego Bruce Wayne, Bullock seems inept but is [[CrouchingMoronHiddenBadass as capable of a fighter as Batman]] when surrounded by bad guys or {{Mooks}}. He also has that "one rule" he'll never, ever, EVER break, for all his flaws, Bullock is one of the few regular Joes in Gotham that will ''never'' take a bribe.

* ''WesternAnimation/TeenTitans2003''
** Red X and [[BigBad Slade]] are both Robin's shadows--X represents what Robin could become if he decided looking out for himself was more important than helping people, while Slade represents what could happen if Robin gave in to evil completely (as Slade is an EvilMentor, he's also a shadow of Robin's actual mentor, Franchise/{{Batman}}).
** Though it isn't really played up, Terra can be seen as Raven's shadow. Both are {{Dark Magical Girl}}s with powers tied to emotions, but Raven practices intense self-discipline to keep herself on the good guys' side, while Terra is an emotional wreck who doesn't really mean evil, but turns out to be very susceptible to serious temptation the first time it comes down the pipe. Raven calls Terra out on how much she has to work to control her powers while Terra won't take that responsibility.
** To a lesser extent, Raven and Jinx. Raven tries to be a hero in spite of being the daughter of an EldritchAbomination (and being one herself when she gets angry enough), while Jinx became a villain solely because she figured [[BadPowersBadPeople her 'bad luck' powers couldn't be used for good]].
%%** Blackfire is in many ways the Shadow of her sister Starfire. They even have [[Creator/HyndenWalch the same voice actress]].

** [[Characters/AmphibiaKingAndrias King Andrias Leviathan]] is one to Sasha Waybright. Both were the de facto "leaders" of their trio of friends (Sasha, Marcy and Anne, and Andrias, Leif and Barrel) who was betrayed by a friend who had the absolute best of intentions and ultimately turned out to be right (Anne turned against Sasha because she was going to hurt the Plantars, Leif stole the [[spoiler:Calamity box because she realized using it would lead to disaster]]). Both let the bitterness of that betrayal to do terrible things, including driving away their remaining friend (Sasha tried to conquer Amphibia and manipulated Marcy and Anne, Andrias became a [[spoiler:cruel tyrant and exiled Barrel]]). The difference between them is that Sasha eventually realized that she was in the wrong and swore to do better, whereas Andrias [[spoiler:didn't realize that Leif was right until a thousand years had passed, by which time it was too late for him to make amends]].
** [[Characters/AmphibiaTheCore The Core]] is one to Sasha Waybright. The Core is a ControlFreak spent years prior to the show manipulating and gaslighting Andrias (and presumably every king before him) into following it obediently, belittling him and convincing him that he's nothing without it. Similarily, Sasha is also a ControlFreak who orders her friends around, acting like their leader and insisting that they'll be completely lost without her. Darcy even gives Sasha a NotSoDifferentRemark during their duel. The difference is that Sasha genuinely cares about her friends despite her manipulative tendencies and eventually grows out of them, whereas the Core only ever saw Andrias as a tool and never moves past its cruel ways.

*** To [[Characters/TheOwlHouseLilithClawthorne Lilith Clawthorne]]: [[spoiler:The background paintings in Belos' mindscape reveals that he had a similar relationship with his brother as Lilith had with Eda: They were close as kids and shared a childhood dream (joining the Emperor's Coven for Lilith and Eda; becoming witch hunters for Philip and his brother), then they later grew to resent and betrayed their sibling just before a fated duel (Lilith with a curse, Philip with a dagger). However, while Lilith didn't mean to permanently curse Eda, rightly blamed herself, and dedicated her life to trying to fix her mistake, Philip ''did'' mean to kill his brother, blames said brother for his own murder ("it hurts every time he chooses to betray me"), and doesn't make Grimwalkers to try to have his brother back, but as an "improved version" of his brother. Lilith also tried to persuade Eda to fulfill their childhood dream of her own free will for years, while we see that Philip ''never'' cared about his brother's or subsequent grimwalkers' wishes or free will.]]
