In some stories the Big Bad casts a shadow over everyone: They might be afraid of him, they might be his minions, or they might be the heroes trying to defeat him. Then there's this guy.
A certain type of character falls outside this pattern: a villain too ambitious or individualistic or just too stubborn to accept the supremacy of the Big Bad. Instead, this villain actually dreams about overthrowing the guy everyone else fears and taking his place. Sometimes he is a (grudging) servant of the Big Bad; sometimes he is entirely outside the established power structure. Either way, if the Big Bad ever stumbles or shows weakness, the Starscream will be there, ready to kick him out of the Astrotrain.
Depending on the nature of the character, he may be an over-optimistic fool or someone who might actually be able to pull it off. If the character isbadass enough, the heroes might be forced to try and stop him from toppling the original villain. Usually fond of playing Commander Contrarian to their boss' schemes (deservedly or not), who will normally Neck Lift them into kowtowing to their will. It can be hard to justify why the Big Bad keeps them around and doesn't Shoot the Dangerous Minion, but it may most commonly be so the Big Bad has a reason to always keep his guard up (and thus can rest assured that he will never become too complacent).
Differs from the Reliable Traitor in not always working for the Big Bad and in his reasons for working with the villain (if indeed he does so).
Not the same as The Dragon getting a promotion when he survives the Big Bad's downfall — that's Dragon Ascendant. Also not to be confused with Dragon Their Feet, where the Big Bad's right hand man screws his boss over by being strangely absent at a bad time. Compare and contrast Dragon with an Agenda, who has different goals from the Big Bad but is at least nominally loyal and generally won't turn on the Big Bad unless said goals are threatened.
If The Starscream succeeds in taking over the mantle of Big Bad from his superior, the former Big Bad may have actually been a Disc One Final Boss. If he was consistently portrayed as the more dangerous or important of the two to begin with, then he's also a Dragon-in-Chief.
Quite strongly related to the Rule of Two, where this is expected and quite nearly mandated. Also often carries strong undertones of Ambition Is Evil.
Many examples can end up being The Millstone if their schemes consistently screw up the Big Bad's plans enough to let the heroes keep pulling off wins.
See also Bastard Understudy, with a similar attitude but more subtlety and patience, and The Dog Bites Back, for when the attacker has not planned but takes advantage of weakness (and/or Right Makes Might if said attacker was actively abused by his new victim.)
Heroes almost never have this problem, because while sometimes subordinates do turn against them, they rarely stay with the heroes afterwards, as a Starscream often does; (maybe this is one big reason heroes win far more often than villains do; they do not make a habit of allying themselves with folks who they obviously can't trust). The Lovable Traitor is probably the closest counterpart on a hero's side, but even folks like that rarely ever have malicious intent like the Starscream does.
Often involves Nice Job Fixing It, Villain. All examples prone to contain Chronic Backstabbing Disorder.
Sub-trope of Evil Versus Evil. Opposite trope of The Creon, who will do anything in his power to stay second-in-command at all costs. Contrast Sarcastic Devotee, Professional Butt-Kisser, and Villainous Friendship (where The Dragon and the Big Bad trust each other as friends).

The Trope Namer is the most famous example, a Decepticon who is, in most versions, The Dragon to Megatron. His treacherous goals could not be more obvious.
The character's intentions were probably first mentioned when the first version of his action figure (one of the first three Decepticons along with Skywarp and Thundercraker) was introduced in 1984. His profile on the back of the card that the figure came in mentioned his desire to lead the Decepticons, but Megatron was not mentioned by name.
His best effort game in the episode "Starscream's Brigade", where with the aid of the Combaticons, came within an ace of successfully usurping Megatron.
In one episode, Thundercracker considers usurping Starscream's position only to be caught in the middle of planning by Starscream, who threatens to tell Megatron.
In The Movie, Megs-into-Galvatron actually kills Starscream, only to find himself as The Starscream to Unicron, with no better success than the original—less in fact, because Unicron is now the source of his power.
In the post-movie season, Starscream comes back and then proceeds to backstab Unicron. While a ghost. Oddly enough, backstabbing a Transformer Physical God works out better for him than when he was only up against Megatron—he gets a new body out of the deal, and Unicron gets nothing except a mismatched new pair of eyes that may or may not have been destroyed at the end of the episode. He then somehow ends up a disembodied spark who wandered for eons and, possibly due to running out of Megatrons and Galvatrons to backstab in his current time-frame, probably decided to follow one through a space-time fissure to keep up his old hobby. Truly the bot has Chronic Backstabbing Disorder.
Leozack of Transformers Victory also qualifies as a member of the Starscream club. Deathsaurus/Dezaras eventually wised up and threatened to kill him if he continued his treacherous ways. Then there's Hellbat, whom the Transformers Wiki even describes as "a member of the Ambitious Screwups club". Thing about Hellbat is, his ambition lies in overthrowing Leozack as the leader of the Breastforce—making him the Starscream to the Starscream.
The Starscreams in Transformers Super God Masterforce and Transformers Headmasters would be Dauros and Mindwipe, respectively. Except Dauros is too dim to be deceptive and often openly challenges Blood's leadership, while Mindwipe's ulterior motives are wholly unrelated to usurping leadership of the Decepticon Headmasters in the first place.
In the Marvel US G1 Comics, Shockwave is The Starscream for a long while, and actually succeeds in wresting power from Megatron on a few occasions. Starscream has a few memorable moments, opting for big power grabs that still fail, but not as blatantly or stupidly as his animated counterpart.
Except in the Underbase Saga, where Starscream manages to trick two factions of Decepticons and the Autobots into fighting each other then gains control of the Underbase and kills virtually every Transformer in existence before blowing up. After that, you wonder why any Decepticon commander would recruit him: Megatron made sure he brainwashed him first and Shockwave couldn't afford to be choosy but Scorponok had no excuses.
In the Marvel UK Earthforce stories, Starscream is surprisingly successful, managing to blackmail Soundwave into helping him depose both Megatron and Shockwave so the two of them can take over as joint leaders.
In Regeneration One, Starscream was lobotomized by Megatron to prevent any further betrayals. It still didn't work, thanks to Shockwave's intervention. (Apparently Megatron either forgot to, or couldn't, lobotomize him.) Later, Starscream was able to backstab Galvatron, which itself was risky considering the time-traveler was already restraining himself from killing Starscream yet again.
The IDW version is a mix of G1 and a bit of Armada, a deadly and powerful warrior who used to see Megatron as a great hero (and cried with joy when he first met Megatron, really) and helps him by assassinating the senate, a few million years later and now he thinks Megatron has lost sight of the end goal and purpose.
In the storyline, Starscream has convinced Bumblebee to let him join the new Cybertronian government, proving helpful in stopping renegade Decepticons still operating with their own agenda in the post-war world. He genuinely seemed invested in making this new arrangement work, and even befriended political rival Metalhawk. When the Decepticons rise up under Megatron he helps stop them, then he kills Metalhawk, blames his death on one of Megatron's Decepticons, sways public opinion to him, and becomes the ruler of new Cybertron, exiling those who wouldn't renounce their old allegiances- Bumblebee and other Autobots in major positions included, and no exceptions made for any of his former allies from the Decepticons, either.
It's around the time of the spoilered events that Starscream picks up his own treacherous lackey: IDW's version of Rattrap. Starscream is not blind to Rattrap's ambition, and in fact seems at times to openly challenge Rattrap to try something.
In an interesting inversion of the 1986 movie, in IDW's "Dead Universe Arc" (Spotlight: Galvatron, parts of Devastation and all of Revelation) the Starscream to Nova/Nemesis Prime is a version of Galvatron who borders on the Magnificent Bastard.
Interestingly, Ramjet got killed outright, whereas Starscream's punishment - having a hole blasted through him pointblank, was something Megs knew might not be fatal, and allowed him back in after.
Terrorsaur, in Beast Wars has the same M.O. as Starscream, with the same suspicious lack of permanent consequences (though it might be explained by Megatron's lack of robot-power). Terrorsaur did succeed at defeating Megatron when hyped up on supercharged Energon, but the effects didn't last long and Megatron eventually recovered.
In one episode, Terrorsaur somewhat succeeded after using Rattrap to capture Megatron (It Makes Sense in Context), only to have the Maximals advancing on their ship and Megatron mockingly asking him what his move will be as leader now. Terrorsaur panics, makes a lot of poor decisions and in the end is shamed in front of the Predacons who refuse to follow his lead any longer. Megatron = Magnificent Bastard.
Tarantulas took over this role after Terrorsaur's death at the beginning of season 2, but his motivations are a lot more mysterious and sinister than simple ambition, he had this role by the midway point of Season 1 as the seeds of his agenda became to be spread, and considering speculation and clues that he really works as Unicron's "spawn", and was at the very least a Tripedacus Council agent, he may have been loyal to someone. Maybe.
In Possession, the actual Starscream showed up, possessed Waspinator, lied about his past, then betrayed Beast Wars's Megatron, then betrayed Optimus Primal, then betrayed Megatron again...only to be betrayed in the end by Blackarachnia. Interestingly, Blackarachnia and Dinobot were the only ones who knew enough about history to see this coming, and Optimus ultimately uses this to his advantage.
Dinobot joined the Maximals only after an unsuccessful attempt to take over, and remained a heroic version of this to Optimus, though never violent when Optimus was incapacitated in various ways he would always fight Rattrap and Rhinox for leadership. Though once, after Optimus was killed (he got better, as Optimuses are wont to do) Rhinox was not in the mood and Dinobot backed down.
All There in the Manual states that Megatron himself was this to his former boss, Cryotek. Considering examples above and below, the only fully loyal Predacons were Scorponok, Inferno, and the Rubber Ducky (best summed up in thisLil' Formers strip: "I managed to keep at least two of my troops from betraying me! Two!") It appears that Megatron actually encourages treachery in some of his more competent troops. He's studied them so well that he's able to guess their schemes and incorporate them his own while lettingthe traitorthink they're still in control. Megs only seems to really get pissed when a betrayer does their plan poorly. Best shown in "Master Blaster", when Tarantulas and Quickstrike betray him as he takes the spark of G1 Megatron into himself, is tossed into a lava pit, emerges with his new dragon beast mode, and proceeds to punish Tarantulas. Then he tells the scheming spider "I can suffer your treachery, Lieutenant, but not your INCOMPETENCE!", and tosses Tarantulas into the lava, remarking "Treachery requires no mistakes".
Meanwhile, the Beast Wars II version of Starscream wasn't like this at all (instead being Ambiguously Gay)... instead, the Megatron counterpart Megastorm was the ambitious screwup constantly trying to subvert Galvatron's leadership, with Galvatron looking the other way because Megastorm was also his brother. However, BW2 Screamer wasn't above trying to backstab his co-minions in an attempt to move up the food chain, and he even tried dunking Megastorm into a pit of Unicron-mojo to get rid of him. (Megastorm got better. Much better.)
In the first two parts of the Unicron Trilogy, Starscream is 1) desperately in need of Megatron's approval, and when he doesn't get it , he defects (following a little prompting from Sideways), and, later, 2) a zombie. In the third part, however, Transformers Cybertron, he's both a truly scheming The Starscream, and surprisingly successful. It comes to a head in "Showdown", where Galvatron is stunned, bordering on horrified, at the prospect that he might actually lose to Starscream. Take the original Starscream, remove all 80s cartoon villain stupidity, and add three levels in Badass (Only three?).
In Transformers Armada, if Starscream isn't living up to his name, the role is usually being filled by Thrust.
Starscream was shockingly proactive, almost succeeding in assassinating Megatron in the first episode and finding himself on Megatron's bad side immediately after. Then in the season two finale, his clones do this to him. Oh, the irony. Unlike most of his other incarnations, Megatron has essentially no tolerance for Starscream in this setting. In fact, since Starscream is immortal due to an Allspark fragment, Megatron kills him several times over, but Starscream did get the last laugh on Megatron in the finale. Posthumously.
The excellent Transformers spoof Incredible Change Bots has Wheeee, the expy for Starscream, do this when Shootertron falls... only for Shootertron to get back up and berate him. ("Shootertron, you haven't fallen!" "No, I just fell. That laser blast put me off balance.")
Some fans have theorized that during the big battle royale, Starscream subtly does this by transforming into one of the good guys' Air Force jets and firing a few shots off at Megatron before flying away. Not really confirmed by Word of God, but was more of Ascended Fanon. "It makes sense with the character, but would only really affect the sequel." This has appeared in the IDW Sequel/Prequel comic, which makes it at least mostly canon, though another version has him considering this but ultimately deciding against it. Revenge of the Fallen, actually confirms this incarnation of Starscream's treachery where it is revealed Starscream deliberately left Megatron to die just so that he could take over. Naturally, Megatron comes Back from the Dead and is pissed off to know this, so Starscream attempts a half-assed explanation.
What's different is not only is this Starscream a pretty good leader, but the reason he's a Decepticon (you can change sides if you want) is because he's trying to keep the Psychos For Hire in check and wants to kill Megatron for the good of all Cybertronians. (For the uninitiated, this Megatron is about as sane as Galvatron. And Galvatron is not even remotely sane.)
In IDW's The Reign of Starscream comic, Dreadwing is The Starscream... to Starscream himself. Starscream's method of dealing with him is about as pragmatic as Animated Megatron's method of dealing with his Starscream, except with less of "Death Montage" and more of "throwing one of the guy's allies into his spaceship". (READ: Starscream kills Dreadwing. By ripping out hisspark.)
The Decepticon version of the game adaptation for Revenge of the Fallen (The DS version of that version, more specifically) has an interesting twist to the usual Starscream methods: After defeating Optimus Prime (the final boss), The Fallen will essentially relieve Megatron from command, and Starscream then informs the player (after snubbing Megatron) that he'll constantly attempt to attack him when he least expects it, strongly implying that his methods are actually his way to ensure whether the De Jure head of the Decepticons remains fit for command.
In the DS game of the first movie, Starscream is surprisingly successful; he takes the player in as a protege to defeat Megatron and is more of a threat to the rest of the Decepticons than the Autobots. Although he failed in preventing Megatron's revival, he did manage to kill Bumblebee, Barricade, Blackout(and presumably Brawl) and take control of the Allspark. Megatron finally took him out in the final boss battle..Which also made him the last surviving Transformer, as he killed the player afterwards.
Transformers: Dark Of The Moon has Sentinel Prime, who not only betrayed the Autobots, but also attempts to become this as well. Alternately, as Sentinel is pretty obviously in charge of the Decepticons by the end, Megatron could be considered The Starscream instead.
Starscream: Decepticons! Megatron has fallen in battle! I, Starscream, have taken my rightful place as your leader!
Megatron: Starscream, you halfwit, I still function!
Transformers: Exodus comments that Megatron keeps Starscream around mostly for two reasons - firstly that his skill and cunning in battle actually exceeds his ambition, and secondly, that Starscream couldn't be more obvious about his goals if he had personally stencilled "I WILL BE PRIME" across his chest. Additionally this Starscream has different political agendas to Megatron; he desires control of the Decepticons mostly to have the robot-power to advance them.
Transformers Prime puts another twist on the character, Starscream wants to be in command and often IS in command while Megatron goes off on his own, and he actually makes for a pretty competent commander. But while he enjoys power he does little to actively take over; he would rather wait for opportunities to present themselves. Mostly he assists Megatron faithfully and warns him against dangerous risks several times.
Megatron revealed that he was aware of Starscream's schemes from the beginning. This Megatron feels that if someone is capable of overthrowing him then he deserves it - it's even suggested he enjoys the threat to stay sharp. But he gets upset when Starscream becomes pathetically predictable. The episode "Partners" reveals that Starscream, for all his weaknesses and flaws throughout his various incarnations, is a very important part of the Decepticon war machine and if either captured or becoming a rogue agent he could wreak havoc against them with intelligence alone.
Eventually when sufficiently punished and humiliated by Megatron, this Starscream shows he is finally content to have the power of SIC. Unfortunately he still doesn't want to settle for anything less; when he lost this position he attempted to switch sides, just to have allies to side against Megatron. He finally gets his hands on Prime's equivalent of the Cyber Planet Keys, all four of them, and... uses them to convince Megatron to let him back in instead of keeping them. Currently he appears loyal, but 99% of fans are anticipating an eventual return to backstabbing. The writers probably want it to be a surprise.
Then, in "Deadlock", his rage upon seeing Bumblebee kill Megatron indicates that his new loyalty was genuine after all.
Starscream did utter the line "Even if it pains me, I do try to be teamplayer" in a flashback.
While not a very enthusiastic member of the 'Cons to begin with, Airachnid took on this role after Starscream left. When Megatron was acting so irrationally even the generic troops were getting antsy she stepped in as a leader, though Soundwave effortlessly shut down her power play.
In Spotlight: Megatron, Megatron explains to Starscream exactly why he has put up with him all this time. Megatron believes that Starscream is a vital part of the Decepticon war machine because he keeps Megatron from becoming complacent. Starscream is a constant reminder to Megatron that he needs to watch his back.
Anime and Manga
Hagall from Ah! My Goddess. In fact, she's only introduced when she's actually successfully deposed Hild as the leader of hell. Unusually for this trope, she did this because of her Undying Loyalty to Hild. Hagall usurped Hild because one of Hell's laws states that when the current ruler of Hell's term expires, the ruler must also die.
Spectra tries to usurp Prince Hydron in Bakugan: New Vestroia. It's unknown if Hydron actually knows of Spectra's machinations, but he's still going to get labeled as a traitor...because Mylene convinced the prince to retreat from New Vestroia and blame Spectra for the Vestals' failure there. She then tells the other Vestals, who think the prince is useless, that "he'll make a good fall guy", revealing that she is also planning to usurp both Spectra and Hydron.
Utegawa in the Bount Arc tried to take control of Jin's scheme, but failed to account for Jin's bodyguard.
Barragan was this to Aizen. Barragan was originally the ruler of the Hollows and was overthrown by Aizen. He wanted to take his kingdom back but died unable to achieve it.
It's eventually revealed that Gin Ichimaru was this to Aizen as well.
Near the end of Chirinno Suzu, Chirin actually teams up with the evil wolf just so he can be powerful enough to kill him.
Code Geass: For most of the series, Prince Schneizel el Britannia appears just to be The Dragon to his father Emperor Charles, and shows no signs of disloyalty. However, as soon as other senior figures in the Britannian Imperial government begin to doubt the Emperor, Schneizel jumps at the chance to take the throne for himself.
Does Schneizel el Britannia qualify? By the middle of R2, he clearly has no respect for his father anymore and is clearly angling to hear "Yes, your Majesty" rather than "Yes, your Highness." In fact, he even puts out a hit on his own father, only to have his half-brother beat him to it. The only reason to hesitate is that, for all of R1 and the majority of R2, he's perfectly content with his role as Prime Minister, and its only after he starts feeling that his father is a hindrance to The Empire that he begins to plot to take the throne. Most people in Schneizel's situation, when told that the Emperor did not care about "mundane" issues, would consider a coup to put in effective leadership too.
Schneizel mentions Damocles in season 1 - and considering what Damocles is, it could not have been built by Todomo in the one-year time skip. And in the Suzaku of the Counterattack manga, he kills the Emperor and becomes the Big Bad.
It's hinted at/foreshadowed by Schneizel himself in an R2 episode that the only part of the Damocles project that hadn't been completed was the development of nukes powerful enough to make the plan work.
Shapiro Keats. He makes it pretty clear that his ambitions reach higher than working for Muge Zorbados. Unfortunately, he alienates Luna, a very important potential ally, and Zorbados betrays him first.
Digimon features this in its fourth season. Mercurymon, the Legendary Warrior of Steel that was turned evil, was more interested in bolstering his own power than following Cherubimon's orders. Cherubimon knows this, but doesn't consider him a threat, and indeed, even though Mercurymon proved to be the most intelligent villain the series, the power he managed to get through an elaborate Xanatos Gambit proved nowhere near Cherubimon's power.
Vegeta was essentially this to Freeza until his Heel-Face Turn. Freeza was aware of this, but was so far out of Vegeta's league that he never considered him a threat and that when he did turn on him he could kill him easily. He proved right, but Vegeta managed to be a Spanner in the Works regardless.
Majin Buu is this to Babidi.
In the anime/manga Freezing, Elizabeth Mably, third year student and second strongest of west genetics, has never liked the lenient rule that her President, Chiffon Fairchild, has on the student body. Mably feels that the rules should be enforced more strictly up to the point where they become law. P.S. Elizabeth has never liked Chiffon herself either. Mably even went as far as forming her own entourage to counteract the peace and quiet that her boss already established, effectively making her a "starscream".
Fullmetal Alchemist: Greed to Father in the manga, and to Dante in the 2003 anime. They're also his creator, but he'll attempt to backstab as he's too greedy to be a team player. They both know this about him and use the knowledge to get rid of him when he isn't useful.
Roy Mustang is the heroic version of this to King Bradley. He's fairly subtle and very patient, but all Roy's nearest and dearest and most of high command know, especially Bradley. They let him play; they could kill him anytime, but he's extremely useful and essentially harmless, considering all the cards they hold and that he'd never compromise far enough to really get into their circle.
Not killing Roy eventually does come back to bite them, however, since letting him around for the series when he knows that his superiors know he's plotting against them gives him time to launch a coup.
Kimbley is this to Greed in the first anime.
In F-Zero Falcon Densetsu, Zoda at one point sabotages the Crystal Cup race by disabling the astro-shields protecting the track floating in orbit around Earth from being bombarded by meteorites as part of his plan to get rid of Luna Ryder. Soon Black Shadow appears in his Black Bull to rescue her from the meteors and takes a hit from one of them making Zoda think he got rid of Black Shadow as well. With that, the overjoyed Zoda decides to take over as new leader of Dark Million, but what he didn't know was that the Black Bull that took a hit from the meteor to save Luna was a copy sent by the real Black Shadow. As soon as he returns to Black Shadow's throne room, he sees to his surprise that both Black Shadow and Luna are still alive. Voicing his suspicions that Zoda would try plotting something to get rid of her and the fact that he came up with a plan of his own to save her, he then gives him what he deserves for all the trouble he went through by pulling on the cord connected to his head and yanking it hard enough to cause him to scream in agony as oil spills all across the throne room.
Black Shadow: I suspected you would try plotting something to get rid of Luna. So I came up with a plan of my own to save her. Luna: You deserve something for all the trouble you went through. Zoda: No! That's not necessary! Black Shadow: It certainly is. (yanks Zoda's cord and causes oil to start spilling) Zoda: AAAAAAAAGGGGGGHHHHHHHH!!!!
This isn't the only time Zoda acted Starscreamy — he continued to attempt annihilating Luna and overthrowing Black Shadow many more times throughout the series before his final appearance.
Suspage of Gaiking: Legend of Daiku Maryuknows that he's better than the rest of the Compass Generals and is determined to prove it, whether by simply besting them or by foul play. His one attempt to actually kill Proist is what leads to his downfall.
Gundam has a long and noble history of Starscream villains. Observe:
Gundam ZZ saw Glemy Toto, originally one among many inept Harmless Villain enemies, do an abrupt turn into one of these pretty quickly. The sudden change was brought about by Tomino receiving the go ahead for Chars Counterattack, and Magnificent Bastard Char Aznable receiving his own plot not coinciding with ZZ.
Gyunei Guss, Char's scheming underling. Though taken in as an orphan by Neo Zeon, Gyunei seems pretty mutinous against his boss from day one, and his desire to obtain the affections of Quess Paraya spurs him into action pretty quickly.
The infamous Frost Brothers from After War Gundam X, who betray nearly every single faction they side with to engineer a war...all in retaliation for not being acknowledged by the Earth Sphere as Newtypes.
Now we have Zanald Beihart from Gundam AGE, who is not happy about Zeheart given full authority over Project Eden and becoming Zeheart's Number Two, willing to destroy Zeheart as well as Earth Federal Forces.
InuYasha: Naraku had something of a problem with this. Hakudoushi was the ultimate example of this trope, followed very closely by the baby and Mouryoumaru.
The Band of Seven experienced this. Renkotsu planned on betraying his leader Bankotsu by acquiring enough jewel shards to become powerful enough to defeat him, including stealing Jakotsu's jewel shard (ensuring his death). As it turned out Bankotsu knew of Renkotsu's treasonous intentions, but wanted to give him a chance to redeem himself. Ultimately Bankotsu ended up killing Renkotsu, proving that he was never a real threat to him; Bankotsu even helped Renkotsu acquire all the jewel shards in his possession just to show his superiority over him and the futility of his efforts and also claimed a superior sense morality before ending Renkotsu's life, exposing him as a complete and utter failure. (It doesn't help that, well, Renkotsu killed Jakotsu, who was Bankotsu's best friend and completely devoted to him.; that was the final push/excuse that Bankotsu needed to go against him.)
Loki, one of the Eight Fists of Ragnarok in Kenichi: The Mightiest Disciple attempts this against the gang's leader, Odin. Going so far as to assemble his own group of Fists and attempt to convince Odin's Dragon Berserker to become the new leader. Loki failed, due to Berserker's lack of interest in being in charge and was promptly beaten down by the unpredictable fighter for his effort.
Oskar von Reuenthal from Legend of Galactic Heroes is somewhat of an example. He actually is loyal to Kaiser Reinhard, but also a highly ambitious person himself. After Reinhard openly told Reuenthal to come at him whenever he wants if he really wants to challenge him (which he did rather because he just suffered a Heroic BSOD, not because he actually thought Reuenthal considered treachery), he begins to contemplate treachery but is kept in check by his good friend Mittermeier and his loyalty. It just goes to show what a conflicted person he is. He later does commit treachery, but more out of pride (which makes him a classic example of a Tragic Hero) and not because he wanted to overthrow Kaiser Reinhard. Reuenthal knew he would fail and in the end shows that he's still loyal to Reinhard after all.
In Makai Senki Disgaea all hell inhabitants have this as mandatory trait. Etna serves for Laharl with hope to backstab him and take throne. She finally admits her ambitions to her master, who then just says, it would be unusual if it was in other way.
Mazinger Z: Two Dr. Hell's servants fit the trope: Viscount Pygman and Archduke Gorgon. The former disobeyed orders the whole time and finally betrayed his creator, taking over the Institute on his own and refusing handed over the control of it to Hell. The later allied himself with Hell but spend the whole time insulting and scorning Hell and his henchmen, undermining his authority and scheming to overthrow Hell at the first chance. He was successful. Gorgon subverted the trope slightly since he was not planning replacing Hell with himself but with the Emperor of Darkness.
Orochimaru suggests that Kabuto may be planning on betraying him, but in the three instances in which he appears to be planning to do so, he remains loyal to him (It helps that he started out as one of Orochimaru's former Akatsuki partner Sasori's spies).
Sasuke also did it to Orochimaru. While Orochimaru was thinking all along that Sasuke wants to obtain more powers and would happily give up his body in return, Sasuke not only obtains those powers, but absorbs Orochimaru instead using Orochimaru's own technique.
In the Three-Tails arc, Rinji appears to be planning to betray Kabuto and usurp his position and gets killed offscreen for it.
Hidan, as he has expressed his desire to kill his leader, but has no real desire to lead, he just wants to kill people.
Now that Kabuto has mastered Orochimaru's remains and Edo Tensei, many think he's in a position to be The Starscream to Madara Uchiha now that he's allied with him. Some evidence is how the Edo Tensei zombies are performing in the first battle of the war- like Deidara not attacking like he normally does and Sasori being under armed for combat.
The speculation was likely true, but Kabuto is defeated by Sasuke and Itachi before he gets the chance.
In chapter 637, Obito manages to ruin Madara's plan to become the Juubi Jinchuuriki, by himself becoming the Jinchuuriki.
NEEDLESS: Saten, Arclight's right hand man (which is exactly what Saten means) strikes against his master when he it as his peak of power.
In Neon Genesis Evangelion, Gendou Ikari is this to SEELE; he goes along with their plan for the Human Instrumentality Project for as long as he feels he has to, at least until the time is right to start his own Instrumentality.
Hannyabal is the Vice-Warden of Impel Down, subordinate to Magellan, the Warden of Impel Down, is so ambitious that he outright states his ambitions to be warden himself in earshot of Magellan, and makes several attempts to get him in trouble, including allowing escaped prisoners Buggy the Clown and Mr. 3 to pass him. Unfortunately, their stupidity forced him to beat them up and capture them. The only time he deals with troublesome prisoners other than this is when his own job is on the line, as Luffy and Inazuma charging into Level 6 of Impel Down. Despite all of this, he works hard at his job and believes in their collective mission, so much so that Magellan will only allow Hannyabal to be his replacement. Hannyabal eventually succeeds, becoming the warden while Magellan was demoted to vice-warden.
A flashback reveals that Portgas D. Ace, of all people, started out as one before developing fanatical loyalty to Whitebeard. This is exactly as Whitebeard had hoped, as he had wanted Ace to be the next King of the Pirates anyway.
New Blackbeard member Avalo Pizarro, after some setbacks outright challenges Teach for his post as Captain. He steps down after Lafitte threatens to kill him, but who knows later...
Technically, Blackbeard himself could be considered a double Starscream since he was under Ace's command before defecting and starting his own crew. What makes it worse is that he succeeded in having both of his superiors eliminated, defeating and capturing Ace and turning him over to the Marines, thus leading to his execution then attacking Whitebeard when he was at his weakest with an army of the most powerful pirates that were in prison, followed by somehow using his Devil's Fruit powersto stealWhitebeard's own. Offhand, it would appear that Blackbeard became the most powerful and unopposed pirate in the series. Hopefully Luffy can give him a run for his money. He also betrayed The World Government by defecting from the Seven Warlords of the Sea after his crew's raid on Impel Down.
Queen's Blade has a weird aversion of this trope: Despise having all the personality of one, and even despise having the power for pulling a one, Elina seems to be happy with her role as the enforcer of her family, rather than be a leader. The closest thing to be a Starscream is Melona, and even her is not interested in ruling, just in having fun with her opponents rather than leadership.
This is one of the reasons why Count Vance (Leina and Elina's biological father) distrusts Claudette, but just like Elina, she's more or less happy with her role in the family, despise having her own, not-so-evil, ambitions. She later pulls one, but not by her own will, thanks to Leina after winning the tournament and forfeiting the title to her, and her father went into large after the rest of the nobles went after him for that move from Leina.
Uonuma Usui of Rurouni Kenshin fits this trope and loudly so: he's actually told Shishio that he intends to kill him first chance he gets. Shishio is confident that said chance will never come, so he keeps Usui around because he's a handy killing machine who, while waiting for that chance, will happily slake his bloodlust on Shishio's enemies. Later on, Saito provokes him by saying that Usui knows he can't beat Shishio, so he's secretly happy to just hang around as one of the Juppon Gatana. He's right. This prompts a Villainous Breakdown when points out that Shishio is likely also aware of it.
Quamzin, the overzealous Zentradi warlord in Super Dimension Fortress Macross. While Vrlitwhai is a charismatic Magnificent Bastard who is just so cool that he manages to keep his Bad Ass persona even after his Heel-Face Turn, even when he blatantly says he's only doing it to save his own skin, as Boddole-zer would kill him and his fleet for being tainted, Quamzin is just a dick who will stab anyone (especially his own superiors) in the back for another chance to attack the humans, or, well anyone else, really. He's such a loose cannon that the other Zentraedi have given him the epithet "Quamzin Ally-Killer". He's not really interested in taking control of the Zentradi fleet though, he's just Ax-Crazy and doesn't care about collateral damage among his allies.
In Tamako Market, Kanna makes no secret of her plans to steal the baton club captain seat from Midori.
Subverted in Tenchi Universe, where Princess Ayeka is accused of being this. She's not just being set up, but the one who does so is the Big Bad Kagato, who wants to force Ayeka's old fiancé and the real heir to the throne (Tenchi's grandpa Yosho/Katsuhito) into a definitive fight.
Tower of God: Kim Lurker had it with his bratty, immature leader, the son of his employer. So, he made Rapdevil ambush Prince after making sure that his subordinates captured Yeon and then became the most menacing villain of the series for a brief time.
For some part of Archie Comics' Sonic the Hedgehog, Robotnik's nephew Snively served as his increasingly untrustworthy lieutenant, and eventually set in motion a plan to destroy Robotnik. In "Endgame" he actually succeeds in erasing the original Robotnik from existence.
Robotnik/Eggman has stated that he knows that Snively and several of his Grandmasters are planning to turn on him, but precisely because of that they serve him to their fullest, because they want to take over a strong empire. He actually applauds Lien Da for an underhanded attempt and chastises Snively for a sloppy one.
Eggman has another reason for encouraging his Grandmasters to plot against him, he actually finds it fun to have enemies to defeat, seeing it as just a game to him. But he wants them to be aware of the consequences if they lose.
Also there's Miles, Tails' Evil Twin from Moebius. Originally loyal to Scourge (Sonic's counterpart), he eventually convinced the rest of the Suppression Squad to turn on him, and soon after set himself up as their new leader.
Conquering Storm is a low-key one but any advantage she see against Eggman, she more then willing to take such as providing Snively with the Iron Oni to use against Eggman.
Lien-Da Desposed of her Great-Great-Grandfather to gain the role of Grandmaster and tried to overthrow the Iron Queen. This didn't work out too well however.
She is currently one to Eggman. He in fact saved her from dying because he's amused by having his underlings trying to kill him as part of his "game."
Kragok was this to Lien-Da - he had agreed to share power as the Grandmaster after they did away with their father, only for him to take the entire thing.
Weasel of Deadpool fame (during the latter's Villain Protagonist arcs). He's nowhere near as scared of Deadpool as someone with his proximity and history should be, and Deadpool speculates in front of him that he might be one of these - but he's just too useful to kill.
The Penguin's Number Two, Ogilvy, takes advantage of his boss being distracted by the Joker's return to completely take over his operation, becoming the Emperor Penguin, the most powerful crime boss in Gotham, while the original Penguin is left powerless and broke.
In the Marvel comic book stories of G.I. Joe, Serpentor immediately becomes this to Cobra Commander. He successfully coerces Cobra Commander and Destro into a situation where they apparently get killed and then takes control of Cobra. Unknown to him, to Cobra and to the Joes, the two actually survive; they part ways and the Commander breifly conspires with one of his Crimson Guardsmen, who eventually kills him out of anger when CC has a Villainous BSOD moment. (Long story; He does come back... almost 40 issues later!) This Guardsman then completes his Starscream moment as he decides to take the identity of Cobra Commander and wrest control of the organization from Serpentor. The Baroness, being the only one in Cobra at the time who has the credit of having seen Cobra Commander's true face, goes along with the ploy and proclaims to the whole organization that he's the real deal. Serpentor, unable to prove her wrong, then goes back to Starscreaming; plotting behind this Cobra Commander's back to get rid of him and bring Cobra back under his control.
Mongul of the Sinestro Corps. Subverted in that Sinestro had a backup plan in case of an insurrection or attempted leadership coup. It doesn't end well for Mongul.
And before Mongul came onto the scene, Superboy-Prime was the Starscream, planning to betray the Sinestro Corps' "guardian", the Anti-Monitor, and kill him in revenge for the Anti-Monitor's destruction of Prime's entire universe.
Sinestro himself played the Starscream as well, back when he was still a Green Lantern. He had major plans to dethrone and murder his superiors, the Guardians, due to his belief they were doing a poor job running the universe (which, all things considered, probably isn't far off).
Bleez began sowing seeds of discontent among the Red Lantern horde once the ongoing series started, which partially resulted in Atrocitus restoring her intelligence. She's made her ambitions much more apparent since then.
In a straight up subversion Alexander Luthor from DC's Crisis CrossoverInfinite Crisis knew that it is generally impossible for anybody to control somebody that's as insane as The Joker so he did not even try. The Joker was VERY unhappy that he was not picked for the team as Luthor eventually found out.
Darth Wyrrlok is an unusual example- he betrays his master Darth Krayt only because he feels this best serves Krayt's own goal of a Sith-ruled galaxy. As he puts it: "Sometimes for the dream to live, the dreamer must die". High Moff Morlish Veed from the same series is a more traditional example, though his own shortsightedness means he generally winds up a pawn for more competent players.
In the Fleetway Sonic the Comic series, Robotnik also had to fight against Commander Brutus, a robot with an indestructible body and a copy of his own brain patterns, who started off as Robotnik's Dragon and then rebelled against him. Robotnik himself was briefly The Starscream when he was allied with the Drakon Empire and and then to Princess Kupacious both times he succeeded.
The Kingpin's son Richard usually works for him, but there have been times he has tried to oppose him secretly, usually taking the masked identity of the Rose (and later the Blood Rose, a more martial and violent version of the previous identity). Richard eventually tried to convince his mother to help him, but her loyalty to her husband was far greater than it was to her son; she shot him in cold blood.
In "The Council Era", a Mass Effect fanfic taking place around 83 CE (in the first half) , both salarian advisor Tyrin Lieph and krogan advisor Halak Marr eventually overshadow their respective bosses (The Council for Tyrin, Krogan Overlord Kurvok for Halak) in terms of power and prominence.
Tyrin is temporarily Councilor after the asari Councilor gave him the title, and later was elected as Councilor after the salarian Councilor's death. Before this, he consistently manipulates the Councilors in order to further his own gains. He'd been conspiring to push himself into the upper political echelon in order to "improve" the galaxy as he saw fit for approximately 30 years. Telia and Roraan (the Councilors he served) were just collateral damage when he finally could start making ripples in the galaxy.
Halak forces Kurvok into retirement and becomes Overlord, but this is long after Marr began pulling the strings and became the real driving force behind the Krogan Rebellions.
The Immortal Game: In a similar vein to Dusk and Dawn above, Nihilus obediently obeys Titan's orders to hunt down the Mane Six — so she can take the Elements of Harmony (which Titan doesn't know exist) from them, corrupt them, and use them to overthrow Titan and establish herself as the new ruler of Equestria.
Inner Demons: Shortly after her Face-Heel Turn, Scootaloo reveals herself to be plotting against Queen!Twilight Sparkle — as she explains to Rainbow Dash, she'll help Queen!Twilight crush the heroes and conquer Equestria, then stab her in the back and take the throne for herself, making herself look like a hero in the process.
Jafar the Evil Vizier in Disney's Aladdin. (Name probably inspired by Mir Jafar, below.) His lifestyle is as the Mind Control-equipt Power Behind The Throne to the weak sultan of Agrabah, with ambitions only to obtain greater magical power, but as Jasmine's coming-of-age threatens to introduce political competitionnote in the form of Jasmine coming into a queen's estate and being able to get rid of him, rather than in the form of her prospective husband staking out his own turf, he conceives an intent to marry into the succession.
Eventually after securing the genie he just makes a wish and is sultan of Agrabah, which is thinking kind of small compared to some versions of the story given it appears to be a wealthy little oasis city all by its lonesome in a bunch of dunelands, maybe a lesser cousin of Samarkand. Anyway he turns the real sultan into a court jester. He did not like pretending to respect the guy.
Points for his coming up with the succession thing within the story, and from Iago's suggestion. No Hikaru Genji Plan here, folks!
Phoebus does this to Frollo in The Hunchback of Notre Dame, especially when after freeing himself, he takes leadership of the people he was ordered to oppress, and turns them on Frollo's soldiers.
Shenzi from The Lion King is actually this to Scar, especially after he took over the Pridelands and kept everything to himself, causing the hyena and her fellow comrades Banzai and Ed to become embittered of him and start spending time trying to overthrow Scar. When Scar loses in a fight against Simba at the end of the film, the hyenas finally confront him for the very last time and succeed in their plot of killing Scar.
In The Secret of NIMH 2, the original villain Dr. Valentine, who barely gets a few lines, is replaced by Martin, who now fancies himself the ruler of Thorn Valley.
Scott Evil takes over Dr. Evil's empire at the end of Goldmember. A variation in that he only gradually becomes this over the course of the series, as his suggestions are constantly ignored and he attempts to earn Dr. Evil's approval. It's only at the end once Dr. Evil has his Heel-Face Turn that he finally snaps.
Then again, he was able to make far more managing legitimate enterprise than Dr. Evil ever could with his schemes, so from his perspective, he's just Surrounded by Idiots.
Ostensibly Jack Napier in Batman, though it's hard to tell if it's a straight example or a subversion. While he was the one who killed Carl Grissom, he did not do so as part of a plot to take over. He killed Grissom out of revenge, and then decided to take over his empire as an afterthought. Then again, comments Napier made in passing to both Alicia and Lieutenant Eckhardt suggest that he may have been plotting Grissom's murder sometime in the future, or at the very least was waiting for the old man to die.
Lord Sopesian and Lord Glozelle seek to overthrow King Miraz in The Chronicles of Narnia: Prince Caspian by provoking him into accepting Peter's challenge of a mano-a-mano sword fight in hopes that he'll be killed. When this doesn't happen, Sopesian stabs Miraz in the back. Glozelle gets a Heel-Face Turn, though.
In the book, Glozelle is the one who stabs Miraz to death, as revenge for his ex-leader insulting him before the duel with Peter takes place. Both him and Sopesian end up killed in battle.
In Elysium Delacourt plans a coup because she feels the current president doesn't have what it takes to lead. Kruger later kills Delacourt in order to seize control of Elysium for himself. Karma's a bitch.
Hector Barbossa from the Pirates of the Caribbean films was this to Jack Sparrow. Originally, Barbossa was Sparrow's first mate, until one day he and several other pirates on Sparrow's ship decided to get rid of their captain by throwing Sparrow overboard, and as a result Barbossa becomes their captain instead.
Repo! The Genetic Opera has three Starscreams—the Largo siblings. Each of them would happily topple the other and can't wait until their father dies so they can get the top spot. Until the end of the film, where their father's crushing rejection of all three of them in favour of his ex-wife's kid causes Luigi and Pavi to stand behind Amber as she takes over the company.
Modus operandi of virtually all Sith in Star Wars, who tend to be just waiting for their Master to slip up. Creator of the Rule of Two, Darth Bane, even applauds it in his apprentice when he finds out she would have supplanted him if he had lost certain battles. In fact, the rule was created because the Sith spent more time fighting between them (playing this trope straight) than trying to rule the galaxy/fight the Jedi, among many other things, but since the average Starscream is usually not strong enough to off their boss directly, or they'd be the boss. Same with the Sithnote The idea with the Rule of Two is that the master would train the apprentice until they inevitably could learn nothing more and killed their master, starting the cycle anew. In practice, most Sith are so power-hungry and impatient that they will kill their master before they've even come close to surpassing them, meaning that subsequent generations of Sith are often weaker. Likewise, the masters, paranoid of being offed by their own students, never teach them enough to let them get that strong. The only thing that keeps Sith from bleeding themselves out entirely is the fact that fallen Jedi become new (and better) Sith on occasion; fresh blood, as it were. There are very few instances where the Rule of Two has been properly obeyed. Even Palpatine, easily one of the most successful Sith ever, did not truly beat his master. He murdered him in his sleep by getting him drunk enough to pass out and then electrocuting him with Sith Lightning, and it's hinted he never did learn the full extent of his master's significant power. And without the Rule of Two, it'd be even worse - back when there was no rule against taking more than one apprentice, it was relatively common for two or more to form an alliance of convenience and then turn on each other. The winner in that situation just has to be slightly better than their fellow apprentices.
Plagueis attempted to avert the trope when mentoring Darth Sidious/Palpatine, only for that to backfire horribly when Palpatine decided to kill him off in his sleep. It's also strongly implied that Sidious had also manipulated everything Plagueis did since becoming his apprentice (and possibly even before becoming his apprentice, if Book of Sith is anything to go by) with the latter never realizing it until his death.
Bane based the Rule Of Two off of a holocron left by Revan. True to form, Revan's apprentice, Malak, tried to assassinate him while he was fighting off a Jedi team sent to capture him.
In fact, Darth Maul almost failed a Sith Initiation Test because he was not a Starscream and was completely loyal to Darth Sidious, to the extent that Palpatine had to motivate Maul by lying about cultivating an apprentice (or at least a half-truth) to get him to have enough anger to even nearly kill his master.
Anakin Skywalker (aka Darth Vader) in particular. In Revenge of the Sith, Anakin believes he can overthrow Palpatine and rule the galaxy with Padme, likely foreshadowed in Attack of the Clones with his mistrust in Senatorial politics. Then he tries it again with his son in The Empire Strikes Back and Return of the Jedi. Special mention given because it does not involve the typical Sith MO of killing their masters over power, for it seems more like Anakin does not like how Palpatine rules, and wants to supplant him and perhaps do it better.
In the Underworld series, Kraven is this to everyone. He teamed up with Lucian to defeat the vampire elders, and then turned on Lucian. He's eventually Rewarded as a Traitor Deserves by the last elder Markus, who caught on to this act.
Visser Three is the Starscream to Visser One in Animorphs. Although he is the primary Big Bad and he does succeed.
Subverted (possibly) in that Visser Three isn't actually working for Visser One, he's working for the Council of Thirteen, whom Visser One just happens to be betraying.
Tom's Yeerk somewhat also fits this trope. Near the end of the series, after Visser Three is promoted to Visser One, Tom betrays his leader to further his own ambition.
In Robert E. Howard's "A Witch Shall Be Born", Conan the Barbarian joins Olgerd in raiding. When Olgerd drags his heels about attacking Constantius as promised, Conan invokes this trope.
The Psychlo race in Battlefield Earth seems composed of Starscreams to the point that one wonders how they were able to cooperate enough to set up an empire at all.
Black Company has the Taken, who spend more time sabotaging each other than actually fighting La Résistance. During the Battle of Charm, only Nightcrawler is apparently killed by enemy action: Shapeshifter is said to have been lost under suspicious circumstances, Stormbringer and Bonegnasher apparently kill each other, The Faceless Man and Moonbiter are assassinated and Soulcatcher openly attacks The Howler. Most of them get better.
Soulcatcher herself is the queen of this trope. her plan in the first novel was to join the treacherous Taken planning to free the Dominator and play them off against the Taken loyal to the Lady, hoping to end up with the Rebel wizards, the other Taken and the Lady dead, leaving herself as the only person of power in the land, with the Dominator unable to free himself unassisted.
An unusual example comes from the Chronicles of Prydain. Originally, Arawn, the dreaded Death Lord and Big Bad of the series, was the consort and servant of Queen Achren, the ruler of Prydain in the series backstory, who taught him all of her secret arts. Arawn used this power to betray Achren and become Lord of Annuvin, at which point Achren became The Starscream to him.
Used interestingly in the Chronicles of Thomas Covenant. Lord Foul'sCo-Dragons are the three Ravers, who, per the backstory, actually predated his arrival in the Land, but joined up with him and willingly allowed themselves to be Demoted to Dragon when he arrived because they were drawn to his power and cunning, and have served him loyally ever since. That said, the dynamic works because Foul is more powerful than the Ravers and they know it- if they ever got their hands on a source of power that gave them the advantage, they'd be more than happy to turn the tables and make Foul their Dragon, rather than they other way around. This, not incidentally, is why Foul never simply has the Ravers (who are incorporeal possessing spirits) possess the main character in order to acquire his Cosmic Keystone ring that Foul spends most of the series after- Foul knows far better than to trust his lieutenants with that kind of power, because he knows exactly what they'd do with it.
The nameless artist in The Dark Is Rising novel Greenwitch. He plans to retrieve the canister containing the ancient prophecy from the titular Greenwitch, going against the wishes of his masters. It doesn't end well for him.
The Divine Comedy features a whole segment dedicated to this, in the ninth and nethermost circle of hell. At first we have Caina, for betrayers of family; then Antenora, for betrayers of nation; then Ptolomea, for betrayers of friends; and finally, Judecca, for...this trope. All are in a frozen lake, befitting their "cold-blooded" crimes. Even if you did it because your boss was evil, you go here.
The wizard Raistlin Majere of the Dragonlance novels was one of the most ambitious, planning to overthrow the all-powerful evil dragon goddess who was the chief villainess of the earlier books and to ascend to godhood to take her place. Actually, he wanted to eventually destroy the whole pantheon of Krynn and to become the sole new deity of the world. He managed it, too, although Time Travel, a horrifying vision of what would happen to the world if he succeeded, and an appeal from his twin brother stopped him from destroying the world. He chose Redemption Equals Death.
Logno in Chapterhouse: Dune. She succeeds in killing the Great Honored Matre, but she doesn't enjoy her victory for long. The main Honored Matre force falls shortly afterwards, and she herself dies.
The Forgotten Realms Dark Elves. Not only do they pursue the blessing of their goddess, The Goddess of Chaos, Lolth, which leads to a lot of squabbles, itself, but their entire race is just a pile-up of this. Families strive to climb the ranks and eventually join the council. On top of that, each elf strives to position him/herself as the most important in their family, under their matron mother. AS WELL AS becoming the highest rank in their chosen profession. (The children of the families can become priestess, warriors, or wizards.) If you can't guess, this leads to a LOT of backstabbing. And frontstabbing. And poisoning. And... Well, let's just say that the leading cause of death for Dark Elves is other Dark Elves.
Drake from the Gone series seems to serve this role to Caine-though Caine is certainly the mastermind villain, Drake would easily overpower him if he'd been blessed (or cursed) with something better than his weird whip-arm. According to Word of God, Caine is sociopathic, while Drake is psychopathic, so they compliment each other's strengths and weaknesses.
Penny assumes the role after Drake goes rogue and outwits and enslaves the more powerful Caine. Unfortunately, she has not thought beyond her moment of triumph and has no backup plan when Caine's other followers are not impressed.
The Consul in Hyperion is sent to the Ousters to spy on them. He goes there, betrays the whole human race by revealing vital information, and gains the Ousters' trust. Then he hijacks a base, kills the Ouster technicians and fire a weapon designed to destroy the anti-entropic fields surrounding the Time Tombs, thus releasing the Shrike. So he acted as the Starscream to both sides. Then he got sent on the Pilgrimage. The other pilgrims, after realizing this, can't be bothered, because they figure this pilgrimage will kill them anyway, and won't make a difference.
In I, Lucifer, Luce is rightly cautious about his absence being known in hell, as he'll likely be usurped. He figures that Astaroth will attempt to move against him should he learn of his "holiday" in typical Starscream fashion. Instead Uriel, whom Lucifer mistakenly thought loyal, has decided to take leadership and move against heaven whilst Astaroth fights loyally to maintain Satan's throne.
Keys to the Kingdom has Superior Saturday and the Piper, who both want to oust Lord Sunday and replace him as the new ruler of the House.
Lensman. This behaviour is actually approved of among the various alien races opposing Civilisation due to The Social Darwinist nature of their society. It's believed that if a subordinate does succeed in usurping his superior, then the Big Bad was no longer fit to hold the job in the first place. Among the "good" guys, the Palainians operate under this paradigm. Nadreck is loyal because he knows any of his three fellow Second-Stage Lensmen can kick his "spiny tokus" if he tries to cross them - and he'd also have Mentor of Arisia on his case. He can, and gleefully does, use every dirty trick in the book, and more, against the Bad Guys.
Saruman of The Lord of the Rings. His dreams of using the One Ring against Sauron were mostly left out of the films. And in the end treachery helps save the day. When Merry and Pippin are captured by a mixed band of orcs, Saruman's orcs insist on taking them to Isengard. En route, the orcs are wiped out by the Rohirrim, and the hobbits escape. If the orcs had gone to Mordor, it's unlikely anyone could have stopped them from reaching the Dark Tower—and Merry and Pippin would have spilled the whole plan under torture. One ringwraith (or even two trolls) standing guard at Mount Doom would have put paid to the quest.
Subverted in the second Mistborn book. Zane continually tries to kill his lord and father Straff, but he turns out to have no real desire to succeed- he hates Straff to be sure, but would rather just let him lead his armies and rule his kingdom, as Zane has no desire to do this himself. The assassination attempts are just because Straff, being in his own way as much of a paranoid psycho as Zane, expects assassination attempts and Zane simply obliges him. At one point Zane thinks to himself that if he really wanted Straff dead, Straff would alreadybe dead. Also, Zane's one moral seems to be that "a man shouldn't kill his father".
John Dread from Tad Williams' Otherland is a Psycho for Hire mentored and kept on a short leash by Corrupt Corporate Executive Felix Jongleur, who uses him as a special "enforcer". As powerful as Jongleur is, he badly underestimates the ambition and cunning of his subordinate, who uses his Technopath powers to take over control of the Otherland network at the worst possible time for his boss and his plans, and thereby successfully graduates to Big Bad.
Quite a lot of Redwall's villains have a Starscream. Lantur in Marlfox succeeds.
Zwilt the Shade is another notable one, as he virtually becomes another "main villain" when he seems to kill Vilaya.
Speaker-To-Animals in Ringworld, and during the journey to the Ringworld itself, Speaker would pull this shit every ten pages, and each time would be EASILY thwarted by the Puppeteer. It becomes a Running Gag of sorts.
Collectively, the Sisters of the Dark are sort of like this to Emperor Jagang in the Sword of Truth series. They're not trying to take over the Order that he runs, so much as pursuing their own goals while enslaved to him.
In the X-Wing Series, Kirtan Loor gradually moves away from loyal minionhood and towards this. When he's put in charge of the Palpatine Counterinsurgency Front on newly-captured Coruscant while everyone higher-ranked than he is leaves, he gets a lot of autonomy, allowed to harass and terrorize the New Republic any way he wants. Eventually he decides that while he's not an idiot and won't directly oppose Isard, he's not terrified of her anymore, and she won't live forever. Not long after that thought hits, the head of the organization commissioned to neutralize the Palpatine Counterinsurgency Front tracks him down, but not to bring him to justice, just to get him to hit targets that head wants eliminated. Loor agrees, in part because otherwise he'd be either killed or taken to justice, but thinks that Flirry Vorru, too, won't live forever. At the end of The Krytos Trap he does actually turn against them, but to try and seek sanctuary with the New Republic in exchange for some information. It doesn't work out.
During Galaxy of Fear, the series' Big Bad, Borborygmus Gog, is in the payroll of the Emperor, which he's fine with, and often subject to scrutiny and criticism from Darth Vader, which he definitely resents, but the Sith Lord is the Emperor's ranking representative. Gog adjusts elements of his big project, trying to figure out a way around The Force that is Vader's biggest advantage. The project's name? Project Starscream.
In Andre Norton's Forerunner Foray, Ogan finds Ziantha after her return from the past. He tells her that the Jack is holding Yasa captive as a hostage, but he doesn't think he'll trade either the stones or Ziantha for her.
In a way, Scourge of the Warrior Cats series is a Starscream, as he's generally treated as an underling by Tigerstar before slitting his throat and killing him nine times over with the emotion one would reserve for swatting a fly.
Brokenstar served as this to Raggedstar and pulled it off successfully
Tigerstar was this before even becoming second in command by plotting and eventually killing the second-in command, and then after that tried to kill off Bluestar numerous times, all of them failed, with the final time resulting in exile.
Lanfear in The Wheel of Time schemes to overthrow the Dark One, and still has a thing for main character (and old boyfriend) Rand al'Thor, the Dragon Reborn. Despite playing The Dragon to the Dark One's Big Bad, she's pretty solidly on the side of the good guys in the first few books - she imagines that, teamed up with Rand, they'd be unstoppable. note All the Forsaken and many Darkfriends have Chronic Backstabbing Disorder and are practically encouraged to scheme against their immediate superiors. Lanfear's apparently the only one with the guts to scheme against the Dark One himself, however, and spends most of her early appearances protecting Rand from other Forsaken with the hopes that someday they'll be able to use a pair of amplifier artifacts, one of which is usable only by men and the other only by women, to overthrow the Dark One and set themselves up as god emperors- with herself the dominant of the pair, of course. When Rand emphatically rejects her, she doesn't take it well.
The Wheel of Time also has Padan Fain, a Gollum / Agent Smith style wild card who's got a major grudge against both the Light side (Dragon Reborn) and the Dark side (the Dark One), and who (being empowered by Shadar Logoth) is enough of a threat to pull it off.
There's also Mazrim Taim, the leader of the Asha'man in Rand's absence. While Rand has been off ignoring the Asha'man, Taim has been asserting control for no doubt nefarious purposes. Not that anyone except Logain seems to realise this. Taim visibly has to restrain himself when Rand presents him with a pin (as a mark of honour) because it places Taim on the same level as the other Asha'man. He names himself the 'M'hael' (leader), acquires a coat with dragons emblazoned on the sleeves in mimickry of the tattoos on Rand's arms that mark him as the Dragon Reborn, builds himself a palace and chooses Asha'man for private lessons to form his own personal army. However, it's ultimately revealed that Taim is, in fact, a darkfriend himself, making him The Mole rather than this trope.
Live Action TV
The A-Team: In the episode "The Rabbit Who Ate Las Vegas", Hannibal's plan to rescue an innocent professor out from under a Vegas mob boss' nose goes perfectly smoothly... until, just as they're getting away, the boss' right-hand man, Martell, takes advantage of the trouble they've been causing to throw his boss out of a window and frame them for it.
Battlestar Galactica (Reimagined): Tom Zarek starts working to topple or undermine President Roslin as soon as he's introduced, stopping just short of an assassination attempt. After Roslin suffers a Heroic BSOD in "A Disquiet Follows My Soul", he partners with Gaeta to stage a mutiny and take control of the fleet, and shows signs of usurping him as well.
Blake's 7: Features computer hacker Avon on the heroes' side, who constantly attempts to abandon Blake and make off with the Liberator and the fabulous wealth it holds, and makes no secret of this. Eventually, Blake disappears on his own, and Avon wins the subsequent power struggle against Tarrant, putting him in charge; however, by then, he has become increasingly paranoid, decides to continue the resistance, and wants Blake back. When they meet again, he shoots Blake because he is afraid that Blake has betrayed the ideals of the revolution and sold out to The Federation.
Spike, in season 2, and thus well before his himification. As an unwilling minion to Angelus, Spike seemed content to stick to snarky remarks and threatening glares, until Angelus unveiled his plan to destroy the world... and seemed poised to pull it off, too. Spike, who likes the world, was not amused. He promptly betrayed Angelus to the good guys. And this wasn't the first time Spike successfully Starscreamed somebody, either. Initially he was in league with the Anointed One, the late Master's right-hand boy. This lasted all of one episode, before Spike killed the "Annoying One" and took over.
Mr. Trick also became one when he grew tired of being The Dragon for the old-minded Kakistos and left him to be dusted by Buffy and Faith.
If one considers Adam to be Maggie Walsh's Dragon, then he also pulled a Starscream against his creator.
In Angel, Lilah Morgan pulls one on Linwood Murrow, the President of Wolfram & Hart Special Projects Division, but does it with the blessing of the Senior Partners.
The Daleks have repeatedly turned against and overthrown their creator, Davros, only to come crawling back when they are weak, because he is smarter than them. Not smart enough to have realized that when he created a race that thinks they are superior to everyone, that would include himself, though. Subverted Trope in the 2005 revival episode "The Stolen Earth"; the Daleks don't even pretend to respect him this time, and are keeping him as a "pet".
This was quite common with the Master. He would be working with another villain who would turn against him, then he would need the Doctor's help.
In "The Invasion" Tobias Vaughn, playing by Kevin Spacey who also played Mavic Chen, is working with the Cybermen to invade the planet but plans to betray them and rule the world. He ends up helping to defeat the Cybermen but is killed by them.
Farscape: Scorpius upstaging Crais is a rare example of it actually working. Ironic since Scorpius was originally created to be a one story villain to never be seen again. Also ironic since Scorpius technically outranks Crais.
Jayne frequently alludes to his willingness to betray Mal if he feels it will profit him. When Zoe is left in charge of the ship, she semi-seriously expresses concern that the "power-hungry maniac" will kill her in her sleep. However, Jayne is gentled quite a bit after Mal threatens to blow him out the airlock into space.
Simon got to play the reluctant crony version of this in the final episode, "Objects in Space", when the bounty hunter Jubal Early makes him help track down River. Early Lampshades it himself, saying "You're gonna help me because every second you're with me is a chance to turn the tables, get the better of me, and it's the only chance your sister has. Maybe you'll find your moment. Maybe I'll slip." This, in fact, does happen, but Simon, neither being a fighter nor having a gun, loses spectacularly.
Arch-fiend Sylar. Every volume features a major Big Bad either directly or indirectly recruiting him as their Dragon. Because Evil Is Not a Toy, it never ends well for anyone except Sylar.
Emile Danko was this to Nathan Petrelli in Volume 4. When Danko took over he was much worse
Holy Pearl: In this C-Drama, Kagura-expy Hu Ji despises her master and spends a large part of the series maneuvering to wrest power from him.
House of Cards (UK): The whole point of the first series is that the protagonist, Francis Urquhart, decides to take the prime minister out of office through trickery and bribery and become the prime minister himself.
In series 2, Stamper has similar designs on Francis's position - except Francis finds out about and has him killed in a car bomb, framed to look like a terrorist attack.
Intelligence (2006): Ted Altman spends the first season playing this role, setting in motion a number of schemes to undermine and replace his boss as head of the Vancouver Organized Crime Unit.
Kamen Rider Dragon Knight: Gives us Kamen Rider Torque. Fearing a You Have Failed Me, he decides to go after his boss first. It doesn't work out so well, and not for his failure, but his treachery, he winds up being among the first of oh-so-many to be taken out by his replacement as The Dragon, the smooth but sociopathic Kamen Rider Strike.
Plays with this trope in an interesting way, in that Percy — the Big Bad of the show— is himself The Starscream to his superiors in Oversight; he stopped being loyal to them years ago, and keeps secret documentation of all the government's dirty secrets prepped to be released upon his death, thus insuring that they can't assassinate him without bringing down the whole government (them primarily).
Towards the end of Season 1, Percy gained his own Starscream in Amanda, who at some point turned on him and joined with Oversight to take him down; by the time Season 2 starts, Percy is locked up, and Amanda's running Division. More recently, she's become a more classical Starscream towards Oversight, in that she's actively plotting against them, and seems intent to bring them down.
The Office (US): Early in the run, Dwight Schrute is enamored with Michael. As the show goes on, he decides he should be the one running the Scranton branch and becomes the Starscream to anyone who's actually running it.
Astronema herself was a Starscream after being brainwashed by the Dark Specter. (Clearly, that worked only too well. Using the Psycho Rangers had two purposes: fighting the true Rangers (obviously) and weakening the Dark Specter. She intentionally connected their powers to his, hoping that their frequent battles with the Rangers would weaken him enough for her to destroy him and usurp his position as leader of the alliance. (Unfortunately for Astronema, the Psycho Rangers were impatient and unwilling to follow her plans, which led to them being defeated before this plan could succeed.)
Following Darkonda was Deviot in Power Rangers Lost Galaxy. He was easily the successor to Darkonda, once again not after the big bad, but after her powers. In the end, his greed for those powers was his undoing, as he and Trakeena battled into the cocoon containing the ultimate power, causing Deviot's ruthlessness to become infused into Trakeena and destroying Deviot himself.
Some non-dragon villains can also qualify as Starscreams. For example, Power Rangers Wild Force brings us Mandilok, the Mouth General of the Orgs. Having been suspicious of Master Org and finally realized he was actually the human Dr. Viktor Adler, Jindrax and Toxica went to look for a replacement for Master Org, and they found Mandilok. He was more than happy to be of service to them as their new master. Later, after Viktor lost all of his Org powers in battle with Cole, Jindrax and Toxica introduced Viktor to Mandilok and, mocking him out of knowledge that the real Master Org died 3,000 years ago and claiming that Master Org is never coming back, he throws Viktor off a cliff, taking his place as the new master of the Orgs for a while until the reborn Master Org's eventual return.
Grizzaka, the Land Overlord in Power Rangers Jungle Fury, also qualifies as a Starscream. Naturally, he blames Dai Shi for losing the war 10,000 years ago and hates humans even more. This makes perfect sense as, after being revived by Camille, he, upon arriving at Dai Shi's temple, is surprised to see that Dai Shi is now using the human Jarrod as a vessel. Jarrod wants Grizzaka to teach him Zocato, but, naturally, Grizzaka isn't too thrilled about that and simply refuses to take orders from any human. Guess what he does next?
Interestingly, out of all the Starscreams in the Power Rangers series, Grizzaka, alongside Astronema and Mandilok above, is one of the few who actually succeed in overthrowing the Big Bad (not counting Darkonda, who, despite successfully destroying Dark Specter, was unable to survive his final attack), and after his success, he becomes the ruler of the other evil forces until Dai Shi returns and takes back his throne.
And after him come the Phantom Beasts. They are actually loyal to Dai Shi - having thought like Grizzaka back in the original war, and now believing they'd have won if they had followed Dai Shi. (Yes, villains blaming their failure on themselves. You don't see that every day.) However, they believe Dai Shi has been compromised by the will of Jarrod.
But before any of them, there was Naja. He made the mistake of trying to recruit Camille, and his Starscreaming career lasted two episodes before she finished him.
Generally, The Starscream is the less sympathetic of the two, as the loyal Dragon has Noble Demon traits while the treacherous one is all about greed and power, but in Power Rangers Time Force, when you find out what Frax's beef with Ransik really is... ouch.
Broodwing of Power Rangers S.P.D. got the farthest. As he was the arms dealer the Big Badand the various unaffiliated criminals got their weaponry from, he was able to easily step into the role of The Heavy and there wasn't much anyone else could do. (It helps that Broody was the main villain of Dekaranger, SPD's parent Super Sentai series, so it was a lot cheaper to have him as the villain.)
Arachnitor from Power Rangers Samurai is an interesting example of a Monster of the Week that actually tried his hand at becoming Starscreamy to Master Xandred. Sadly, his attempt to overthrow him and become the new leader of the Nighloks didn't end so well for him, and he ended up being mutated through Cold-Blooded Torture as punishment for his betrayal.
Serrator later turns out to be this.
Vrak from Power Rangers Megaforce, on top of already being the Dragon-in-Chief who puts most of the villains' plans into motion, claims to be this when he takes advantage of Admiral Malkor going into his coccoon state late in the season to further his schemes. That said, he never really takes any action against Malkor (though the Rangers don't give him much of a chance), and the fact that it takes so long for him to even claim to make a move ironically makes him much more loyal than his incredibly treacherous Goseiger counterpart below.
The Shield: Shane Vendrell is that series' Starscream, though the writers took a great deal of time (about three seasons) to pull the trigger on his betrayal of Vic Mackey. Though Vic takes him back into the fold once Shane crashes and burns on his own during season four, the reconciliation doesn't last very long. Shane murders fellow Strike Team member Curtis "Lem" Lemansky, when Shane realizes that Vic was stalling on giving the order to kill him, due to Vic's sentimentality keeping him from realizing Lem had to be killed before IAD could break him and bring the entire Strike Team down. This in turn leads to a confrontation for seasons six and seven, between Shane (Starscream) and Vic (Megatron) and Ronnie (Soundwave).
Ba'al who was supposedly in the service of Anubis while he was in fact trying to topple him and take his place. This led him to cooperate with SG-1 to stop Anubis from obtaining a weapon that would give him power over the entire galaxy. Notably, Ba'al betrayed Anubis in this manner twice. Ba'al also stuck around to continue playing The Starscream in the Ori story arc, scheming to undermine the Ori's Take Over the Galaxy plot so that he could be the one to Take Over the Galaxy. And despite perpetually making himself a nuisance or worse to much more powerful Big Bads, Ba'al managed to outlast them all, mostly through being Dangerously Genre Savvy.
The Genii leader Cowen in Stargate Atlantis has Ladon Radim pretend to be planning a coup in order to lure Sheppard into an ambush. When Weir tells him that they are able to cure Radim's sister from near-terminal radiation poisoning, Cowen tells her he does not care - in Radim's hearing. Guess what happens next.
Sulu plots to get rid of both Kirk and Spock, but suddenly finds himself badly outnumbered when Marlena uses the Tantalus Field to wipe out his men.
Garak repeatedly tried to get rid of Intendant Kira, with little success. Kira kept him on because he was good at his job (but not nearly as good at interrogation as Garak-prime).
Archer was The Starscream to Captain Forrest, and in a way to the Imperial Starfleet once he had his hands on the prime universe's Defiant (the one from "The Tholian Web", not the Deep Space Nine battleship), only for Hoshi to betray him and take over.
It appears that this is standard operating procedure for everybody in the in the Mirror Universe.
In the regular universe, Damar wound up as the Starscream to Dukat by killing his daughter, therefore driving him insane. However, this was a subversion. Damar did this because he saw Ziyal as a traitor to Cardassia and killing her in Dukat's best interest, not because he disdained Dukat or wanted his job. Nonetheless, this all put Dukat out of the leadership and second-in-command Damar in his stead.
Damar (who has a very idealistic and naive view of the Cardasian Union and what they did on Bajor) ends up trying to pull one of these on the entire Dominion once they start turning on the Cardasians. All he manages to accomplish is driving the Founders into one more atrocity.
Season 6 gives us Castiel, the local Sixth Ranger Traitor. He and Crowley hatch a plan to set themselves up as the new God and Lucifer, respectively. Their alliance hits a few snags, and ultimately Cas becomes God, but Crowley does not become Lucifer.
Cas had more power than Crowley for most of their working relationship, rather than working under him, and prior to that had joined La Résistance for moral reasons at great personal cost, even leaving aside that he'd already died twice saving the world by this point. He was also becoming God to end a war that he'd started to prevent the apocalypse beginning again. His qualifications as Starscream are slim, but The Dark Side Will Make You Forget is prominent.
Technically, the demon Crowley is also a Starscream, as far as season 5 of the show is concerned. While a servant of Lucifer, he knows that he and the rest of his kind are merely tools of Lucifer and that they may end up being killed by him so he forges an alliance with the brothers so they can defeat him.
Even Sam Winchester qualifies as a starscream for the most part of seasons 1-5, most prominently in season 4. Frustrated by the constant belittling of his older brother, Sam is made to believe by the demon Ruby that he is mankind's salvation and has him rebel against his older brother by the end of season 4.
Similar deal in the series Power Rangers gets its footage from. They vary in how successful they are. Notably, in Choujin Sentai Jetman, Radiguet, the villain that is ultimately the series Big Bad gets reduced to a Starscream ... for only two episodes.
Tensou Sentai Goseiger has the one who takes the cake. At first Buredoran simply knows things the others don't and keeps the real deal to himself, but in the end he's actually using the strengths of all three villain organization to further his own plan. He's a fallen Gosei Angel who wants to use the power that will resurrect everyone for the final judgment at the end of the world to instead erase all life. His supposed bosses were actually so far beneath him it's not funny.
V: The Final Battle: Diana reveals herself to be one of these towards the end. And in the followup TV series, she got one of her own in Lydia.
The Wire: Stringer Bell fits this trope perfectly, killing D'Angelo behind Avon's back, and taking advantage of Avon's imprisonment to restructure the Barksdale Organization under his own model. We like him, because his model is smarter and more professional, and will lead to less violence, but he doesn't get the extent to which Avon only cares about playing The Game, and goes down because he thought it was about making the most money.
The X-Files: Alex Krycek has had a few sneaky attempts at clawing his way to power, including his stint in charge at a Russian gulag, his recurring threats (and eventual attempt) to kill the Cigarette Smoking Man (and when that failed, attempting to ensure his place as CSM's successor) and manipulating Jeffrey Spender. You can practically see him waiting in the shadows, ready to seize power with both hands. Well, one hand anyway.
24: Samir Mehran in season 8. Although, unlike most examples of the trope, he didn't plan it all along, he only decided to overthrow his boss (Farhad Hassan) when said boss proved unwilling to threaten New York with a dirty bomb to force the Americans to give up President Hassan.
David Otunga showed signs of this toward The Nexus leader Wade Barrett. When the Nexus was in a situation where all of the members faced other WWE superstars and Barrett told the other members to either win or be kicked out of the group, Otunga was quick to point out this applied to Barrett as well. He expressed his desire to win a battle royal to determine the #1 contender to Randy Orton's WWE championship, which didn't impress Barrett. On the same night, he tried to make friends with John Cena, knowing that Cena was unhappy being a part of the Nexus and was the most likely member of the group to turn on Barrett. This backfired, as Cena was able to eliminate Otunga and justify his actions by telling Barrett what Otunga was trying to do. He led the Nexus on an invasion of WWE Smackdown (without Barrett) and failed miserably, with Barrett pointing out that the next time he decides to undermine his leadership, he should be successful about it. Barrett for his part seemed well aware of Otunga's discontent, and on a number of occasions put him in some really bad situations because of it, such as forcing him to forfeit the Tag Team Titles to Justin Gabriel and Heath Slater, or forcing him to wrestle Edge with the stipulation that he'd be fired if he lost. He seemed to have the rest of Nexus on his side of the struggle; all of them left Barrett to be beaten down by Cena alone. Interestingly, he didn't seem to have a problem when CM Punk became the new leader of the Nexus.
The Rock became this for Faarooq in the Nation of Domination, and eventually took over and retooled the stable to his own liking.
John Laurinaitis acted as he was supporting Triple H during his early time as COO in 2011. It became quite clear that he was behind the scenes trying to make Triple H look like the bad guy by having members of the roster come to him with their issues, and sucking up to the Board of Directors in order to be appointed as the head of Raw after they decided to take Triple H off due to the walkout. Even Vince McMahon himself was displeased that Triple H, the guy who took over his operating duties, was being overruled by the board.
Kurt Angle was this in the early part of the Main Event Mafia against Sting. Eventually, Angle got fed up with Sting not being evil enough and usurped his control of the group.
The Corporation era in WWF was full of Starscreams. First it was Shane McMahon usurping power right out from under his own father to form the Corporate Ministry. Then it was Vince McMahon taking said power away from his wife (in a double swerve orchestrated with his own son, thus rendering the previous insurrection moot). Then later on in 1999 after the McMahons turned face, Triple H and Stephanie McMahon took control of the company in a very Machiavellian fashion in what was known as the McMahon-Helmsley Era. Stone Cold eventually got involved too as part of the InVasion angle when all of WCW and ECW were a Starscream.
Ring of Honor has an incredibly long chain of them. Alex Shelley was betrayed by Austin Aries who was betrayed by Roderick Strong who was betrayed by Davey Richards who was betrayed by Kyle O'Reilly.
This trope is not limited to the Sith in Star Wars. In the NPR radio plays, depending on the cut you're listening to there's a scene where Grand Moff Wilhuff Tarkin and Admiral Motti are heard plotting to overthrow the Emperor. They get blown up before they can put their plan into effect, obviously, and it's unlikely they would've succeeded in any case.
Mephistopheles in Dungeons & Dragons rules the eighth layer of Baator, Cania. He makes no secret of his plots to conquer the ninth layer, Nessus, and overthrow Asmodeus. In fact, he has said as such directly to Asmodeus's face. Asmodeus, being the ultimate Magnificent Bastard, has absolutely no fear of Mephistopheles and allows him to plot away.
This applies to the rest of the Lords of the Nine as well (they're devils, what do you expect?) to a (much) lesser degree, but most strongly to Levistus. He is still suffering the punishment from his previous coup attempts, buried in ice after killing Asmodeus' consort when he suspected her of betraying one of his schemes. Despite this, he maintains control over Stygia, and the actual reason he was imprisoned was for being too whimsical.
On the other hand is Geryon, a subordinate who was punished for being too loyal, because loyalty is weakness in Baator. Which is ironic, because Dante's Geryon was the "Beast of Fraud".
Baalzebul is a subversion - a Starscream who actually did manage to get punished. Baalzebul used to be the #2 guy in Hell - a demonic angel figure who ruled 2 layers of Hell, one himself and one through another Lord he manipulated. Asmodeus melted him into a sluglike form and demoted him to #3.
Also, Fierna, who is the political ruler of the fourth Hell and technically The Dragon to her father Belia, the true ruler, has not become this - yet. However, the friendship she has developed with Glasya after Glasya's ascent to Lord of the Sixth has her taking a great deal of initiative on her own, and Belia is Genre Savvy enough to be worried that it may come to pass. (As stated above, that sort of thing is all-too common in the twisted politics of Hell.
According to Fiendish Codex II: Tyrants of the Nine Hells, every devil is either a Starscream to his/her/its superior, or at least hopes to replace the superior upon the latter's death or demotion.
Elsewhere in the D&D game, several Ravenloft darklords have Starscreams on the payroll. One of the most powerful darklords, Azalin the lich-king, actually used to be a Starscream, before he left Strahd's domain and service. In so doing, Azalin gained his own domain, so that one was a draw.
The vampire Kas was this to Vecna. The attempted coup didn't really work (at least not in the long term), although Vecna did lose his hand and eye.
The drow from Dungeons & Dragons do this on a regular basis to each other. It's rare to find one in a position of leadership that didn't gain her position by betraying her predecessor. Different noble houses will betray each other to rise in the power structure, individual drow will try to murder and overthrow their superiors, make alliances with enemies and double-cross allies, and so on. That said, they will set aside their bickering and unite against a greater external threat, or simply when their demonic goddess Lloth orders them to, because no one disobeys the spider goddess.
Except, in the fourth edition, where it is revealed that Lolth herself has an exarch named Enclava who has betrayed her not once, but twice. Amazingly, Enclava has not been punished and is still Lolth's exarch, possibly because Lolth can't help but admire her audacity.
Princess Magnificent With Lips Of Coral And Robes of Black Feathers from was forced by her bosses to work for the First and Forsaken Lion; she's not happy about that arrangement at all, and plots his downfall. It's gotten to the point where fans sometimes refer to them as "Princess Starscream and the First and Forsaken Megatron."
The Green Sun Princes are practically designed to be this to their Yozi masters. Half the charms in the Broken Winged Crane book are dedicated to allowing the GS Ps to break free and to become something even more powerful than the Yozis.
Sometimes one Starscream just isn't enough, so the New Phyrexia set from Magic: The Gathering gives us the black Phyrexian faction - The Seven Steel Thanes, which is seven Starscreams, each with their own personal army and each trying to out-stab the other six, as well as any other Phyrexian higher-ups that happen to stand between them and the position of Father of Machines.
Magic: The Gathering loves these. Storyline-wise, Tezzeret is turning into one. But more gameplay-wise, you get your choice of the Lord of the Pit and Force of Nature. Arabian Nights gave us fourdjinnwhodothis. All of which are creatures that are powerful, at least for the cost to summon them, but use up a resource or hurt their controller directly. The Juzám Djinn listed above is considered the best, both among those djinn and among creatures in general when it was introduced. Most new players will still react to such things as "Any card that hurts you is bad," but many experienced players have been more than happy to deal with the drawbacks of creatures like these.
There's also Vhati il-Dal, the ambitious first mate of the Predator, who was placed in charge of the ship when his commander Graven il-Vec was personally overseeing the boarding of the Weatherlight. Fed up with Greven's brutal leadership and hoping to usurp his rank, he fired on Greven while he was still on the Weatherlight. This decision proved ruinous for Vhati.
In the Scarred Lands tabletop RPG, one of the villains is a being called Mormus, AKA The Jack Of Tears, who rules over his own part of the world. He has four lieutenants, and all but one of them is planning to usurp him and betray each other. Mormus's well aware of this, but he lets them continue their machinations just because it amuses him.
The Ventrue see the Daeva as this and they have good reasons for thinking this way.
The Skaven in Warhammer. If a Grey Seer doesn't honestly believe his ascent to the Council of Thirteen, usually by betraying everyone in sight, isn't the only hope for the Skaven race, he's been trained wrong. The primary weakness of the Skaven is that the vitally important role of The Starscream is given to everyone (though since the race breeds like rats, it's probably a vital form of population control).
Warhammer 40,000. Find a Chaos warband, Ork mob, Dark Eldar Kabal, or Imperial planet. Find the next most powerful Marine, next biggest Ork, next most powerful Dark Eldar, or next highest-ranking noble. Congratulations, there's a 98% chance the person you've found fits the bill in a manner appropriate to the race in question. Except the Dark Eldar, as their rate of Starscreaming is close to 100%. The only person in their entire society not trying to overthrow his/her superior is Asdrubael Vect, and only because he has no superior to backstab. That said, although they are viciously competitive, the Dark Eldar will set aside their personal ambition and grudges when it comes time to execute a realspace raid for captives and plunder - they're scheming bastards, but they aren't stupid enough to sabotage their Kabal's success (and risk their own lives) by screwing up the battle plan.
Macbeth in Shakespeare's play of the same name, although we really don't learn enough about Duncan to determine whether he could be considered the Big Bad or not. Macbeth succeeds, but never manages to completely control Scotland and is himself overthrown.
The Ring of the Nibelung, when Alberich has taken over the Nibelung his brother Mime plans to overthrow him, which Alberich is aware off. After Alberich loses the Ring of Power he and Mime compete over it, and Alberich is delighted when Mime is killed by Siegfried.
Manny Coachen to Quercus Alba In Ace Attorney Investigations: Miles Edgeworth. He tried to make Ambassador Palaeno the ambassador of Cohdopia instead of Ambassador Alba when Allebahst and Babahl were going to be reunited.
The Barbarossa campaign of Age of Empires II has Henry the Lion getting ambitious and betraying Barbarossa twice, and then being exiled. As you finish the last scenario, The Narrator says "What of Henry the Lion? With Barbarossa gone, there was nothing to stop him from returning to the Holy Roman Empire. But I'm an old man now. What harm could I possibly do?
Sarevok is an especially competent one. Presumably few ever thought Rieltar/Reiltar Anchev, leader of the local branch of the evil merchant organisation, was really the Big Bad, since it was obviously the guy with the Glowing Eyes of Doom and Spikes of Villainy seen at the beginning. But most of the plot is about thwarting the Iron Throne's actions, largely centering around Rieltar's plans which he has no idea are only a part of Sarevok's own plan. Rieltar doesn't really understand Sarevok and especially hasn't a clue about his motives, which is why Sarevok is able to dispose of him casually at the strategically right moment while Rieltar thinks himself safe.
Played for laughs with Smug Snake Edwin Odesseiron, who often plots killing the hero and his party under his breath, apparently unaware that everyone can hear him.
Amelissan from Baldur's Gate II: Throne of Bhaal fits the bill nicely. While Bhaal could foresee his death, he did not realize his head priestess would be happy to take his place as the goddess of murder instead of reviving him. You'd think a name like Amelissan the Black-Hearted would have given him a clue.
Jade, Emperor Zog's second-in-command in Breath of Fire I, who helps Ryu and his allies throughout the game disguised as a thinly veiled cloaked man with a color swap —- in the process dropping big hints on how Ryu can fight the Dark Dragon Empire right down to letting Ryu know about a weapon (a bottled song named 'D.Hrt') that reduces Zog's HP by half in one blow (and Ryu's to 1). After Zog is defeated, Jade reveals himself, having set Ryu up to defeat Zog to obtain the Goddess Myria's powers all for himself. Later on, Jade's hints potentially end up stabbing himself in the foot —- if the player defeated Zog the hard way without D.Hrt, he/she can instead use it against the mind-controlled Sara (who Jade kidnaps at the start of the game and had kept around for his own purposes) when she transforms into a Dragon and fights the party. This reduces her HP (and as usual, Ryu's) to 1, instead of half.
Dalton from Chrono Trigger, who seems all too eager to usurp the throne the first chance he gets.
Clive Barker's Undying: Jeremiah plotted to use Gel'ziabar stone to drain energy from the Undying King and become a god himself.
In Conkers Bad Fur Day, the Weasel Scientist fits this trope well. At the end of the game, he kills the panther king by putting an alien egg inside him.
In Darksiders and Darksiders II, the Demon, Samael is essentially a starscream to the Prince of Hell, Lucifer, and to his primary general on Earth, the Destroyer aka Abaddon, so much so that the latter had Samael imprisoned for fear of his power.
In Disgaea: Hour of Darkness, Etna openly threatens to become this to Laharl if he should ever step out of line as Overlord of the Netherworld. He has no problem with this because A) it's how demons are supposed to act, B) it's Etna's way of fulfilling her promise to Laharl's father to make sure he becomes a good Overlord, and C) Laharl deeply respects Etna, knows she could do the job well, and would rather she be his replacement than anyone else.
Escape From St Marys: Renuka Desai, in her attempts to overthrow Mr. Souza. The man denies her computer access... and forces her to do his laundry.
Wernher is eventually revealed to be this in The Pitt add-on of Fallout 3. While initially coming across as noble and heroic, and claiming to be an escaped slave, Ashur reveals that he was actually the latter's second-in-command, and wanted to use Ashur's radiation-free daughter as a way to gain power.
Col. Autumn played the Starscream for President Eden. Seeing that Eden is dead and that Autumn can optionally be let go during the final confrontation (albeit with a large portion of his power base broken), he succeeded to some extent.
In Fallout: New Vegas, Benny is this to Mr. House, planning to use the Platinum Chip to take over New Vegas. House is fully aware of Benny's plan, but can't really do anything by himself. That's where you come in. It's later possible to be this to Mr. House with the help of Yes Man, who's originally Benny's trump card. Yes Man himself subverts this in the ending, where he states that he'll be upgrading himself to be more "Assertive". This actually means that he'll be making sure that only the Courier can give him orders so that he can't be used against you.
Father Elijah, the Big Bad of the Dead Money DLC, is this to the Brotherhood of Steel. After they lost HELIOS One to the NCR, he deserted them and fled to the Big MT to find new weapons to use against the NCR and the rest of the Mojave, whereupon he met Ulysses, who told him about the Sierra Madre.
Gharnef is this to Medeus in the Archanea games. But because he carries a magic tome that gives him Nigh-Invulnerability that not even Medeus could remove and Medeus himself could only be defeated a sword that only Marth can wield, Gharnef serves Medeus obdiently while plotting to overthrow Medeus.
Certain storylines in Gunstar Super Heroes have Green overthrow General Gray and seize control of the Empire to avenge his father's death.
The protagonist from Impire makes no secret that he is tolerating his summoner giving the orders because he was bored earlier. At one point when you get invited to betray him by a lich queen, you give a speech roughly equating to that you've got an army to help fight her and you prefer employers who you can kill and eat solo in case you get fed up.
In Jade Empire, Master Li has already tried to steal power from the Emperor once, and in the course of the game he gets his revenge, pulling off a masterful Evil Plan twenty years in the making to become the game's true Big Bad.
The Lotus Assassins ALL seem to have this outlook. Especially Gang toward Shin; after helping Gang kill his direct superior Shin to get his favor, you can kill Gang yourself.
Organization XIII from the Kingdom Hearts series is full of these, most of whom are stationed in Castle Oblivion during Chain of Memories. First there's the Castle's lord Marluxia and his Dragon Larxene, who plot to take over the Organization using Sora and Naminé. Opposing them are Vexen, Lexaeus, and Zexion, who try to derail their plans using Riku. These five are eventually eliminated by Sora, Riku, and Axel, the last of whom was specifically ordered by Xemnas—through his friend Saïx—to do so. Then it turns out in 358/2 Days that by eliminating the potential traitors in Castle Oblivion, Saïx and Axel have removed the potential obstacles to their plans to overthrow Xemnas, which fell apart when Axel ended his friendship with Saïx for one with Roxas and Xion, while Saïx himself ended up becoming too absorbed by the authority he had over the other members to care about betraying Xemnas anymore.
In Mega Man X, Vile is a loyal second-in-command of the Big Bad Sigma. Maverick Hunter X, on the other hand, retcons him into becoming this, especially in his own story, where he decides to take on both his enemies X and Zero and Sigma's Maverick army. Vile also admits in his ending that he actually didn't know if he would have fought Sigma or joined him.
Prometheus and Pandora from Mega Man ZX obviously hate their creator, but they had their reasons for not stabbing him in the back at first - Master Albert had to limit the amount of time they could live in order to keep them under control, since they had to keep going back for maintenance in order to stay alive. But when they do, Prometheus simply walks up to Master Albert, kills him off right in front of the hero, and declares that Albert's "Game of Destiny" was all a farce (Those two are the only villainous characters in the series who actually realised this), and that he and Pandora will destroy everything as part of their revenge. Interestingly enough, they didn't quite succeed. There's a good reason why Master Albert is a Magnificent Bastard - Albert actually faked his death as part of a planthat his own creations unintentionally provided him with, and it's implied that both Prometheus and Pandora are both dead... thanks to their own traitorous actions.
Mr. King from Mega Man Star Force 3 is a shining example of an evil villain with a disastrous (for him) hiring policy. Ace defected to the Satella Police before the game starts, Joker has been serving him to fulfill his own desire for power, Jack and Queen were using him solely to access Meteor G as a WMD, with or without Corvus and Virgo's guidance, and Heartless was only half-loyal so she could try to contact Kelvin Stelar. The man was surrounded by traitors with intellect on par with aforementioned Prometheus and Pandora, and wound up the only human in Dealer to not live to the end credits. Then again, it's not clear whether he died or not after the Crimson Dragon was subdued.
Might and Magic VII's story centres around two groups of strange advisors, one to Bracada's Gavin Magnus and one to Deyja's Archibald Ironfist. Magnus' advisors are not this trope. Archibald's advisors end up deposing him and initiating a scheme to take over the world through superiorscience.
While Shang Tsung is loyal to Shao Kahn in the first three canonical installments, in Deadly Alliance he teams up with Quan Chi to take the realms for themselves. There's also the matter of his endings in Mortal Kombat II and 3, where he kills his former master and conquers both Earthrealm and Outworld. Sort of justified by the fact that you actually need to defeat Shao Kahn with Shang Tsung to get said ending.
Reiko apparently acts as a starscream to both Shao Kahn, whose power (or at least the helmet) he wants for himself, and Quan Chi, who he openly dislikes despite being a member of the Brotherhood of Shadow. In Armageddon, it's hinted that he let Taven beat him so that Taven could continue hunting down Quan Chi.
Quan Chi himself serves as this to Shinnok. In turn, his most powerful enforcer, Noob Saibot, acts as a starscream to him.
If her in-game endings serve as any indication, Tanya is this in spades.
In fact, almost every villain who's supposed to be loyal to Shao Khan has a non-canon ending in one or more games that suggest Starscream-like goals. Since they are non-canon, it's uncertain whether they are true or not.
Shao Khan used to serve as this to Onaga, but unlike most examples he was able to go through with it AND keep the power for quite a long time.
In Advance Wars, Hawke is always a reluctant servant of Sturm, who he eventually kills. In the later games he defects to the side of the four nations and fights against Von Bolt. And the end of the game he shoots Von Bolt (if the player refuses) and apparently assumes control of the Black Hole nation.
In Odin Sphere, Brigan attempts to overthrow Demon Lord Odin by killing his daughter and announcing it to make Odin look bad. Although his plan never even gets to the first act, because Gwendolyn kills him before he can even begin his plan, he does manage to snatch power for a short while because he later possesses Odin from beyond the grave, only to wind up getting exorcised by, you guessed it, Gwendolyn.
Alastor from Painkiller, who turned out to not be upset at all that Daniel helped him kill Lucifer. Also, Eve, who wanted Daniel to kill Alastor so that she could become ruler of Hell herself.
In Pokémon Platinum, Charon somewhat fits this role, seemingly having a completely different agenda than the rest of Team Galactic. This finally comes to fruition when the player goes to Stark Mountain and ends up encountering Team Galactic again, something that didn't happen in Diamond and Pearl. An extra battle with Mars and Jupiter is fought, and then they leave while Charon enters the mountain. He is eventually captured by Looker.
In Quest for Glory IV, Ad Avis hates being magically compelled to serve his master,Katrina. At the end of the game he baits her into breaking the bond by attacking him. He then proceeds to kill her by casting a spell that brings her to the attention of the Eldritch Abomination who's brain the scene takes place in..
Albert Wesker in Resident Evil deconstructs this when it comes to Umbrella due to not only his boss, Ozwell E. Spencer, being aware of backstabbing him, but also orchestrating the plans resulting in Wesker deciding to take down Umbrella.
During a Space Route scenario in Shin Super Robot Wars, the Londo Bell rescues Fonse Kagatie from imprisonment. He relates how the alien attack and Tassilo Vago's treachery brought about the end of the Zanscare Empire (just as Lupe had said), ending in Tassilo imprisoning him in the first place. When the group tells him that Zanscare Empire is still active, he realizes quickly that Char must have taken control. Increasingly panicked, he tells the Londo Bell that they must stop Char before he achieves his misguided goal of robbing all mankind of its emotions, creating obedient soldiers as the aliens want.
Astaroth, in the Soul Series gets a double dose. In the first Soul Calibur, he's working for Big Bad Nightmare. The next game shows that he was really looking for a chance to take Nightmare down, to bring his Artifact of Doom to the cult of Ares which created him - but after failing, he destroys the cult and starts working for Ares directly. By the third game, his endings start showing him trying to kill Ares, as well.
Much like Kefka above, while Luca Blight from Suikoden II may have some subversions, it is generally impossible for anybody to control somebody that insane, as his father, Agares Blight eventually found out. That out of the way, the real Starscream of Suikoden II was the main character's former best friend, Jowy. As soon as Luca is out of the way, Jowy reveals his true plans, and the war continues.
In the Mario & Luigi RPG series, Fawful sort of fills this role. Although wholeheartedly loyal to Cackletta throughout most of the first game, and never actually outright betraying her, in the final fight he has the sudden realization that—* gasp* —he is merely a useless peon, and decides to disregard his boss and fight the titular brothers on his own accord. He then goes on to be the only character exclusive to the Mario RPGs outside of the main four characters of the series (The Bros., Peach, and Bowser) to appear more than twice. In his second appearance he is recovering from his first defeat and describes the events of the first game, but completely neglects to mention Cackletta at all, and makes himself out to be the true villain. In the third game, Bowser's Inside Story, Fawful is the main villain.
Cecile in Win Back, who offs the Big Bad Kenneth near the end of the game, before being temporarily KO'ed by The Mole.
Sho Minamimoto from The World Ends with You has elements of this; while several people want to overthrow the god-like Composer, Sho is the only one who is willing to toy with the exceedingly dangerous and violent Taboo Noise to do such, and the only one willing to chase the Composer to the RealGround (which is to say, mortal life) to do it. In a bit of a twist, the ending reveals that the Composer, Joshua, actually kind of enjoys having such a loose cannon around.
This also fits Mitsuki Konishi. She states on the final day that she would have no qualms whatsoever about betraying Megumi Kitaniji in order to take his place as Conductor. She makes a deal with Minamimoto that she will help him defeat the Composer, so long as she is allowed to be second in command.
According to a Nintendo Adventure gamebook, Wendy O. Koopa is actually this to Bowser.
Blazblue: Kagura Mutsuki, head of the largest of the Duodecim families, has been plotting to overthrow the Imperator of the Novis Orbis Librarium and take her place since Continuum Shift. Subverted: He's actually a good guy, and he doesn't want to take power, he wants to install another person in place.
Gloog from A Game of Fools is constantly trying to undermine Captain Sepultra's authority (and at one point manages to briefly overthrow him), mainly because Sepultra won't allow some of Gloog's moresinister antics.
O'Halloran's constant attempts to usurp the Chairman in Building 12 certainly qualify.
In Drowtales, Suu'be Nori'fu is this to Quain'tana, and hints have popped up in the main story, since Suu'be resents Quain for making her own daughter Koil'doarth no longer be the heir. Rosofsays that if Quain were to let her heir Ariel train under Suu'be Ariel would probably die in an "accident" and Word of God is that Suu'be would try to get rid of Quain if she thought she could get away with it, while on the other hand Quain knows that she can't get rid of Suu'be, leaving them in a state of constantly pulling at each other.
Sene'kha was also this to Kiel's mother Ven'ndia, and it's heavily implied that it was Sene'kha who coaxed Kharla into killing her. After Sene'kha took over Starscreaming seems to have become S.O.P. in the Vloz'ress.
And collectively, all three Sharen sisters, Snadhya'rune, Sarv'swati and Zala'ess, pulled this on their mother, though she didn't know until the moment of the actual betrayal.
Fruit Incest has the Transfarmers characters, in which the appropriately named Starspray and Planescream both plot to overthrow their leader Cottontron as well as each other simultaneously.
Captain Vole from Girl Genius finds himself promoted into this role, Gilgamesh Wulfenbach having decided that having a Super Soldier as The Starscream and still being alive will give others pause if they consider attacking him.
Gilgamesh: We'll make a game of it! "Who's the scariest monster?"
In the kids' session, he has taken on the title of "Sovereign Slayer". He's earned it.
The Condesce shows signs of chaffing under Lord English.
Subverted with the versions of DD, the Post-Scratch Dignitary often talks about ambitions of Condesce or Jack Noir, but while he respects ambition, he really doesn't care to scheme with or against anyone.
On top of being a Dirty Coward, Twp'atwt from the Protectors of the Plot Continuum reveals himself to be this during the Black Cats' attack on HQ; while he had previously appeared loyal, it turns out that he and his lover - Serna Tjan - are planning to overthrow the Bracket Fungus and the rest of the Cats after they've taken over, leaving Twp and Serna as leaders of the PPC. Unfortunately for them, they run into Blue Photon and the MysteriousSomebody respectively shortly after this revelation, resulting in their Karmic Deaths. This was also hinted at in the prior story, The Reorganisation, when Twp'atwt attempted to blackmail the Nightshade and Orchid into making a clone of the Mysterious Somebody that would obey Twp's every command.
A variation in Survival of the Fittest - Hayley Kelly was playing the game in v4 mainly to protect her ex-girlfriend, Ema Ryan. However, when it came down to the wire, almost 30 students left, Ema Ryan decided she could do the rest on her own and killed Hayley, went on to become a late-game player who killed almost the same amount of people Hayley did (about eight, including Hayley herself), but ultimately died of her injuries when there was less than ten students left.
We're Alive has Scratch who is at the very least a Dragon with an Agenda who has set off on her own to get revenge on Pegs for killing Latch. But as of Chapter 24 she may be looking to overthrow Durai.
Gatekeeper was also this to Marcus. In Chapter 19 he staged a coup to take control of the Colony.
To precisely what extent he masterminded his father's death is uncertain, though he was deeply pleased with the results; his initial intent was to maneuver one-up on his brother, the heir Iroh, his father's favorite.
Then Zuko becomes this to his father after being crown prince for half of season 3.
Paxton Powers in Batman Beyond was an odd case. You could technically say he was a successful Starscream killing his father Derek (or so it seemed) and taking over Wayne-Powers as CEO, even though he really only did so because he lucked out. The thing is, Paxton became a rather pathetic replacement, not at all like the dangerous and ruthless tycoon his father was. Squandering his newfound position on wine, women, and song, neither Bruce Wayne nor Terry took him seriously at all, and when he eventually got greedy and doubled crossed the Royal Flush Gang after hiring them to steal artifacts, he was hauled off to jail. (And he pretty much ruined the Royal Flush Gang's once stellar reputation in the underworld in the process. Paxton did threaten to buy the courts and have Barbara Gordon and the rest of the police department working in the sanitation department when his lawyers were done, but that was likely an empty threat. The important thing is, Wayne was finally able to regain full control of his company again.)
In Ben 10: Ultimate Alien Vilgax is eventually Demoted to Dragon by Diagon. When he reappears for the Grand Finale he loudly proclaims his Undying Loyalty to Diagon. Ben immediately calls him out on his bullcrap, believing that the real Vilgax isn't loyal to anyone but himself. Ben is completely right. Vilgax also manages to be a successful Starscream, tricking Diagon into attacking an energy absorbing device — bad news for Diagon since he's an Energy Being — sealing (possibly killing) him.
Makuta Icarax from BIONICLE believes that Big Bad Teridax's (the Makuta) plan to take control of the universe (by putting the Great Spirit asleep and then reawaken him once preparations are complete) to be too convoluted, and prefers to batter people into submission instead. When Teridax was temporary unable to monitor the actions of his whole Brotherhood, Icarax decided to speed up the process by going to war. He had already claimed some areas when Teridax arrived and beat him up. He's only kept alive because of his talent at fighting and the fear he inspires in his foes. After being deevolved by Toa Ignika, he later gets killed by some of his fellow members when he tries to ruin The Plan, making him a historical Starscream. The ones that killed him though suddenly outlive their usefulness.
Roodaka has at least attempted to betray nearly everyone she's worked with.
Which is most amusing since Glove, like Rasp, was voiced by Frank Welker, the original voice of Megatron.
Zero, on Challenge Of The Go Bots. Zero had been the leader of the Renegades, and Cy-Kill stole the job from him after defecting from the Guardians. Zero had every reason to resent Cy-Kill, and he wanted his job back.
In Chaotic, Lord Van Bloot is a lieutenant of Chaor, supreme ruler of the Underworld, that really wants the bigger chair. The latest sets in the card game reveals that he has allied with the M'arillians to achieve his goals of ruling the Underworld (even thought that would just make him a mere governor if the M'arillians succeed in taking Perim).
Rasp from Dino Riders, although not to the consistency of the trope namer. Interestingly, his voice actor was the same who did the voice of the original Megatron, Frank Welker. He also voiced the Big Bad, Krulos. This more-or-less means that he was trying to backstab himself.
In Exo Squad, Draconis regularly plots against Phaeton, but his plans always come to naught. Phaeton eventually gets rid of him anyways.
Typhonus also has a Starscream moment in the first season finale, when he responds to Able Squad taking Phaeton hostage by reminding them that everyone is expendable. It doesn't work out well for him either.
On The Fairly OddParents, the Lead Eliminator eventually tires of taking orders and tries to revolt. He promptly gets "unmade". Though he eventually comes back as a One-Winged Angel, the true villain of the special.
Hilariously enough, this is what Cobra Commander becomes after Serpentor becomes head of Cobra in season two of G.I. Joe: A Real American Hero. However, Serpentor was more than willing to leave Cobra Commander behind to be either captured by the Joes or to die in the miniseries in which he (Serpentor) first appeared. Cobra Commander then pointed out that sooner or later that the rest of the Cobra would realize that Serpentor was not perfect and that a scapegoat would be needed when things fail. Also, Serpentor usually never finds out about Cobra Commander's attempts to kill him. The closest Serpentor got to finding out was in the episode where Cobra Commander summoned an Eldritch Abomination to kill Serpentor, though Serpentor thought that the Joes were the ones behind the attack in the end.
The Baroness gets a moment of this as well in the episode where she obtains a power to subjugate men.
Evil-Lyn, who many a times has worked behind Skeletor's back for her own purposes. There's even been a few times when Skeletor was aware of her treachery. Unlike Megatron, Skeletor doesn't take kindly to this and usually attempts to make her pay with her life. However, Evil-Lyn usually gets lucky and manages to get a little leverage over Skeletor that forces him to accept her back into his ranks. In the 2002 version, her betrayal almost cost her her life and her soul. The show seriously compromised the Never Say "Die" policy when Skeletor tried to punish her by sacrificing her to an Eldritch Abomination which seem to have more than a few things in common with the things you see in Cthulhu Mythos. She survived because her dad told He-Man that Skeletor was planning a Human Sacrifice that would make him more powerful, conveniently leaving out the fact that it was Evil-Lynn. He saved her anyway when he saw it was her (commenting to himself that "I'm probably going to regret this later.") He was right, of course; she wasn't grateful at all. Skeletor later changed his mind, admitting that he somewhat admired her for taking the initiative (although he did threaten a worse punishment if it happened again). And that may well have happened if the series had continued. She made plans to ally herself with Hordak that, unfortunately, were never resolved due to the cancellation of the series.
Trap-Jaw could be considered a serious Starscream too (or at least he was once) if the origin given in his issue of the Icons of Evil limited series comic book (based on the updated version of the cartoon) could be considered cannon. In the plot of the story, he is depicted as far more clever than he is in the cartoon, and he raises an army of warriors from stragglers in the Dark Hemisphere to wage a coup against Skeletor, but fails, the loss of his jaw and right arm (resulting in the cybernetic replacements) resulting from a brutal and bloody showdown with Skeletor himself, which he loses. At the end of the story, he's working for Skeletor again, and when Evil-Lynn asks him why, his response is, "Keep your friends close and your enemies closer."
In the '80s version, both Beast Man and Clawful had Starscreamish tendencies. Beastman only passively resented Skeletor and intended to wait for a good moment, but Clawful threatened to overthrow Skeletor to his face and then laughed off his threats. (Of course, Clawful was dumber than a box of hammers, especially in the remake. Clearly, he wasn't a threat.)* Sarah Bellum was like this in one episode of Where on Earth Is Carmen Sandiego?. This led to a brief Enemy Mine between Carmen and the two heroes, as Carmen was obviously the Lesser of Two Evils. (Sarah was far more brutal.)
Grimian of Hot Wheels Battle Force 5 is an incredibly persistent Starscream, his constant attempts of usurping command from Kalus almost becoming a Running Gag. His last attempt at taking over is heavily implied to be his last. You can only push Kalus so far...
Krocomodo was originally this trope for the Vandals before Grimian booted him out of it.
Another one who actually succeeded is Zemerik. He was originally Krytus' Dragon but gained free will and overthrew him, imprisoned him and his team, then became a Dragon Ascendant, serving as one of the Big Bads in season 1. Unfortunately for him, Krytus was freed in season 2 and took the role back by force.
Valmont in Jackie Chan Adventures betrays Shendu right after he betrays him. He plans on robbing him of his palace, but fails. Next, he pulls an Enemy Mine on Jackie to remove Shendu from him.
Gantu on Lilo & Stitch: The Series. While not actively attempting to overthrow Hamsterviel, he does take opportunities to break away from him. When he got 627 and Dupe, for example.
Mighty Max's Warmonger was Skullmaster's Dragon and Starscream throughout, and temporarily succeeded in replacing him. Skullmaster, in a rare attack of competence, set the whole thing up: Skullmaster being offstage encouraged the heroes to blow the spell that could stop (kill?) him on the Hydra instead.
Ninjago has Samukai, the king of the Underworld who apparently wasn't too thrilled about having Lord Garmadon take the throne from him after being defeated by Sensei Wu. After the ninja bring the Golden Weapons of Spinjitzu to the Underworld, Samukai tries to use him being Multi-Armed and Dangerous to hold all four at once in an attempt to defeat Garmadon but is destroyed in the process.** Later on there's Skales, who understandably believes he'd be better as chief of the Hypnobrai after Slithraa's initial blunder allows Lloyd to use his hypnosis against him. He succeeds in taking the position from Slithraa after defeating him in an arena duel. Over the course of the first two seasons he acts as a Starscream to three masters: Slithraa, Pythor, and Garmadon, overthrowing the first and third while the second does himself in.
In Rocky and Bullwinkle, Boris Badenov tried many a time to stab his boss Fearless Leader in the back. When you're dealing with evil spies, what do you expect?
In the Sonic Sat AM series, Snively constantly grumbles over having to serve the Doctor, but doesn't actually attempt to harm him. By the Second Season he has blatantly come to resent his uncle's abuse and makes a few shrewd plans behind his back (he once attempted an attack on Knothole while Robotnik was gone, as well as making alterations to his base that would ultimately save his life when it was destroyed). He simply plays along until Robotnik is electrocuted in the final episode, then is seen donning his uncle's trademark yellow cape. He does, however, resemble Starscream in voice, especially considering his voice is done by Charlie Adler.
Pretty much everyone's Dragon in the gang war arc of The Spectacular Spider-Man, especially Hammerhead, which is surprising because he seemed to be extremely faithful toward his leader. However, he is understandably fired by said boss shortly after they (or at least the boss) were arrested.
Silver Surfer from The Super Hero Squad Show. He starts out as an ally to the Super Hero Squad, then returns to Galactus with the Infinity Sword. The weapon corrupts the Silver Surfer to the point where he actually becomes more powerful and arrogant. His act of this trope involves what looks like an alliance with Thanos, whose Infinity Gauntlet now has all 6 gems, by shaking his hand. But at the end of the handshake, he rips off the gauntlet from Thanos and banishes him into the gauntlet. He then becomes the Dark Surfer. This is one of the few examples of a Face-Heel Turn pulling this trope off.
In Teenage Mutant Ninja Turtles (2003), Baxter Stockman plays this role whenever he's working with The Foot, and will take any opportunity to be a thorn in the Shredder's side. If you want your Mad Scientist's loyalty, here's a tip: don't punish him by way of Malevolent Mutilation for every single operation gone wrong until he's more machine than man. He can make said machine very big and very nasty, and he'd probably rather use it on you than the Turtles.
At first, Pavel from TRON: Uprising, appears to just be a Professional Butt-Kisser, but is slowly revealed to be this. He leaves Paige to die, keeps a powerful upgrade a secret from Tesler, tries to make Tesler look incompitent in front of Dyson, and then when Paige repeatedly rejects his offer of a Villain Team-Up, he begins to takes verbal jabs at her in front of Tesler.
In W.I.T.C.H., Cedric eats Phobos unexpectedly after Phobos agrees to give 'a fraction of his power' - which he decided to interpret as 3/3, 4/4 or equivalent.
