'''Basic Trope''': A villain or rival dislikes or hates the idea of someone else defeating the hero.
* '''Straight''': [[MadScientist Doc-sci]] [[VillainousRescue saves]] [[ShockAndAwe Electric Man]] from another villain. When asked why, [[AmbiguousGender they]] say that they want to be the one who defeats him.
* '''Exaggerated''': Doc-sci doesn't want anyone else to defeat Electric Man, not even their own [[{{mook}} minions]].
* '''Downplayed''':
** Doc-sci will let other villains defeat Electric Man as long as they feel they are worthy of respect.
** Doc-sci will let others defeat Electric Man if they buy their weapons first to do the job.
** Doc-sci doesn't care if another villain defeats the hero as long as they are there to witness it and/or see the body.
** Doc-sci doesn't lift a finger when Electric Man is cornered, but is relieved when he manages to escape.
** Doc-sci's secret identity [[LovingBully Alex]] prefers to toy around with Electric Man's secret identity [[AcademicAthlete Flash]], yet when someone else tries doing the same, [[HypocriticalHeartwarming Alex makes sure to make that person's life hell]].
* '''Justified''':
** Doc-sci is a very envious person who can't see others living out their dreams.
** It has been prophesied that Electric Man's defeat at the hands of Doc-sci, will lead to the later's complete and irrevocable conquest of the world. HOWEVER, it's also been predicted, that if someone else manages to slay Electric Man, Doc-sci's humiliating downfall will be guaranteed, so they must stop anyone from doing so to prevent their own demise and secure their triumph.
** Electric Man has foiled Doc-sci's plans one times too many, and wants to carry out their revenge against him.
** Doc-sci is actually a StealthMentor to Electric Man.
** Doc-sci is Electric Man's [[ArchnemesisDad parent]] and they genuinely loves their son, even though they're not on the same side of the conflict, and they won't allow their son's life to be put in danger.
** Doc-sci wants to recruit Electric Man, and they can't recruit him if he's dead.
** A villainous wolf saves Debra the Deer from a hunter so they don't lose their meal.
* '''Inverted''':
** Doc-sci wants Electric Man to be the one who kills or defeats them and no one else.
** Doc-sci is a sore-loser except for when they lose to Electric Man.
** Doc-sci doesn't want to fight anyone but Electric Man, no matter how many allies Electric Man has.
** Doc-sci refuses to fight Electric Man and does everything they can to encourage other villains to fight him instead.
* '''Subverted''':
** It turns out Doc-sci was lying and was really setting him up for another trap that involves Jay J. finishing him off.
** Doc-sci decides that if someone like Jay J. can defeat Electric Man, he never was the WorthyOpponent he thought he was.
* '''Double Subverted''': But then Doc-sci realizes they should be the one killing him, not Jay J. and kills Jay J., saying "I've worked too hard for this, trying to defeat him. This is MY reward, not yours!"
* '''Parodied''': Doc-sci acts more like a jealous lover (straddling the line between {{tsundere}} and {{yandere}}) than an enemy, going into hissy fits whenever another villain even approaches Electric Man. On their own time, Doc-sci likes to imagine romanticized showdowns and battles.
--> '''Doc-sci''': B-UsefulNotes/{{Baka}}! It's not like I'm jealous of them or anything!
* '''Zig Zagged''': Doc-sci's action are entirely based on the predictions made by a malfunctioning computer. Sometimes they'll rush to defend Electric Man even when they want him dead, sometimes they'll do nothing to help him when they want him alive, and sometimes they and the predictive computer actually agree.
* '''Averted''': The villain doesn't care if someone else defeats the hero as long as they're out of the way.
* '''Enforced''': The writers don't want to have the hero KilledOffForReal. So they try to have a VillainousRescue with this trope as their justification.
* '''Lampshaded''':
-->'''Doc-sci:''' You think I'd let some nobody kill Electric Man? [[WorthyOpponent You deserves better than a death at HIS mediocre hands]]: ''I'' will be the one to kill him!
--> '''Electric Man''': Why do you even care? I'm going to be dead either way!
--> '''Doc-sci''': Because pride and glory don't work that way, [[PrecisionFStrike you dumb fucking idiot]]!
* '''Invoked''': Doc-sci is unable to betray their villainous organisation for whatever reason, but has already fallen for Electric Man and is using this trope as a cover.
* '''Exploited''': Electric Man public broadcasts his impending defeat, as he knows that Doc-Sci will be baited into rescuing him out of envy.
* '''Defied''':
** "You're about to kill my nemesis? Good. I thought I would NEVER kill him, and I'm happy you thought to prove me right. [[KilledOffForReal Make sure you're ''through'' when you do it though.]]"
** Evildoer Supreme [[MakeWayForTheNewVillains makes sure to kill Doc-Sci]] immediately before attacking Electric Man.
* '''Discussed''': "When a villain has a sworn nemesis, trying to defeat them without permission nor request isn't advisable. Unless you want to be their next target, that is."
* '''Conversed''': "Why do so many villains have a real hate for kill-stealing? Perhaps it's something to do with their self-worth being based on whether they can kill 'their' nemesis or not..."
* '''Deconstructed''': Electric Man was Doc-sci's first love (whether [[DatingCatwoman reciprocated]] [[VillainousCrush or]] [[AllLoveIsUnrequited not]]). As a result, Doc-sci has backwards notions about what it truly means to be in love and views fighting other villains as the same as cheating, only to become a total {{yandere}} and drive Electric Man away.
* '''Played For Drama''': Doc-sci, after years of fighting Electric Man, has fallen for him and is in some serious denial. This causes them to not want to see him get hurt yet at the same time intentionally hurt him themselves.
* '''Implied''': When Doc-Sci sees Electric Man getting the tar beaten out of him by another villain, they silently glare at the latter, and then suddenly rushes over and snaps his neck.
