"Luke, you have not yet realized your importance. You have only begun to discover your power. Join me, and I will complete your training. And with our combined strength, we can end this destructive conflict, and bring order to the galaxy... Luke, you can destroy The Emperor! He has foreseen this! It is your destiny! Join me, and together we can rule the galaxy as father and son."
Say you're a villain and your Evil Plan is being ruined by this pesky hero who just will not let you scheme in peace. You've sent Mooks, you've berated your underlings for their failure, maybe you've even tried shooting him/her. No dice, the hero keeps coming. You can't beat them!
Well, if you can't beat them, don't join them — offer to let them join you. That's right: you can become the partner in crime/trusted advisor/ruler of Australia if you will just drop this silly crusade against the Evil Overlord and get with the program. Go on, those oppressed peasants you're fighting for won't mind — they'll understand that you can't let an opportunity like this slide. The offer is usually made by someone who needs to Pick on Someone Your Own Size with a Circling Monologue.
When this offer is made, it's usually a sign that either the hero or the villain is going to die very soon. If not, it's the hero's final rejection of the villain's vision, and marks the point where things get serious...
Because the hero rarely follows up on the offer. From the human perspective, it's a pretty foolish move anyway. How could any villain ever be serious about hiring someone who's been thwarting their evil schemes every step of the way, especially when it's a morally righteous Cape? How could the villain possibly trust someone treacherous enough to do such a blatant Face-Heel Turn?
In Yu-Gi-Oh! 5Ds, Carly, as a Dark Signer, showed Jack a world where they would rule together as King and Queen. Jack almost fell for it, too bad that his Hamminess snapped him out of it.
Valvrave the Liberator: In the third episode, enemy soldier and ace mecha pilot L-Elf reveals that he wants Haruto to "form a contract with him and serve as his right hand", essentially asking Haruto to become his personal Dragon so that they can bring revolution to Dorsia. Haruto eventually accepts, realizing that L-Elf's genius can potentially minimize the losses his friends will have to face.
In the last episode of season one of Mega Man NT Warrior Lan, fused with Megaman, is fighting with a giant navi-fused Dr. Regal. Our Hero is on the ropes, but rather than taking Lan out, Dr. Regalexplains that he's impressed with him and explicitly states "I want you by my side, Lan." His offer is refused.
The entire ending of the manga is the result of Shiina accepting one of these. After the deaths of her father, mother, boyfriend, best friend and everyone she'd ever cared about, Mamiko asks her if there's any reason left not to end the world. Shiina replies that there isn't.
In an interesting example, in the first Vampire Hunter D novel (and comic), The DragonRei-Ginsei give this offer to D "As two beautiful lords ruling the night" (to paraphrase) - despite that Magus Lee would most certainly have something to say about the attempt to double-cross him.
Diva from Blood+ offers her twin sister Saya this, asking Saya to join her in turning all humans in the world into Chiropterans. Obviously, Saya rejects her.
Actually, one of Diva's chevaliers, Solomon, who is in love with Saya repeatedly offers her the chance to join them. Diva doesn't care either way and her main chevalier, Amshel, who made the offer first, quickly decides against having Saya join them; possibly because of how bitter the sisters' relationship is and seeing that nothing will dissuade Saya from killing Diva.
Creed from Black Cat practically lives this trope. According to him, his entire plot to rule the world will always be incomplete if Train isn't by his side. It could be said that he is the most persistent character in the entire series, offering Train this countless times.
Tabool from Now and Then, Here and There, a child soldier whose predicament has driven him to the brink of scathing insanity, tries to convince his sane best friend Nabuca that they can take over Hellywood together. Strange subversion in that Nabuca refuses, but it's Tabool who winds up killing Nabuca.
Senator Kurt Godel proposes that to Negi in Mahou Sensei Negima!, apparently for the sole purpose of getting him angry. It works wonders.
Or was he serious after all?
His true offer? He wants Negi to take up Queen Arika's legacy and become King. Apparently. In the end, Negi nearly does take him up on it, but ultimately rejects it, as Kurt's Fantastic Racism means that he would only save about an eighteenth of the population. According to Negi, Arika would have tried to save everyone, so if he's going to follow in her footsteps, he's saving everyone too.
In Berserk, the Apostle and Dark Magical Girl Rosine offers this to her best friend Jill. Who refuses, so Rosine abducts and tries to transform her into one of her followers instead.
Later, Emperor Ganishka offers Guts a position in his army so he can get revenge on Griffith. Guts tells him to fuck off.
In Pokémon Special, Red was given the offer twice with Team Rocket and The Elite Four. Both times he refused, though the outcomes were quite different. First time, epic battle which he barely wins thanks to a Chekhov's Gun. Second time, not so lucky as he ends up as a Human Popsicle.
In the first episode of Transformers: Robots In Disguise, Megatron offers to let Optimus Prime join him so they can despoil Earth together. Optimus, naturally enough, refuses.
In the Ocean dub of Dragon Ball Z, Vegeta makes this offer to Goku. Goku turns him down, not only for moral reasons, but pointing out that Vegeta killed his last right-hand man. This is changed back to the original dialogue of Vegeta bragging about how he was going to kill Goku for the Funimation re-dub.
A lot of DBZ villains try this. Vegeta, Frieza, King Cold, Zarbon, Raditz, Turles... probably a bunch of others, too.
This actually goes all the way back to Adviser Black from the original series. After taking over as leader of the Red Ribbon Army, he offers joining forces with Goku, even going so far as to propose first using the dragonballs to revive the man Goku is trying to bring back to life. Goku still refuses.
Maoyuu Maou Yuusha has an interesting take on this trope. The Maou wants the Yuusha to work together with so they can end the war between their races peacefully with the least repercussions and enough benefits for everyone. They also note that offering to rule together is considered standard procedure for a Maou (one of the manga adaptions shows a picture of the Dragonlord with a Censor Box over his eyes during this explanation), and lampshade how a real hero would never accept such an offer.
Later, the spirit of a previous Maou who's possessing the current one makes a similar offer. The Yuusha again points out how ridiculous it is to expect a hero to accept such an offer.
In chapter 581 of Naruto Kabuto actually asks this of Sasuke twice. He refuses the offers.
After killing Neji and giving Naruto a Hannibal Lecture about his naivety and inability to protect everyone, Tobi asks Naruto what he even has left in this reality and invites him to stop prolonging his suffering and join he and Madara. Naruto hesitates, but Hinata snaps him out of it.
Madara asks Sasuke about this in the recent chapter. Of course, his offer has been refused.
Kirge Opie offers Apacci, Mila Rose and Sung-Sung the chance to join with the Vandenreich. They refuse. Since he has a join or die mentality, he obliterates them.
Yhwach makes this offer as well. To both Aizen and Ichigo. They both refuse. Yhwach doesn't mind. He planned for that.
Katekyo Hitman Reborn!: In chapters 385, 386, and 387 Bermuda asks Reborn to join him and says he likes him and wants him (for his team). Reborn refuses and Bermuda responds by capturing him.
At the height of his madness in the finale of the 2003 Astro Boy series, Dr. Tenma takes over the Ministry of Science and demands to see "Tobio" again. Fully believing that Astro is Tobio, he asks him to join him. When Astro refuses, Tenma snaps completely and tries to commit suicide.
Queen Beryl from Sailor Moon offers Prince Endymion the chance to join her and rule over her kingdom (and presumably whatever else she conquers) during her attack on the Silver Millennium. Naturally, he refuses which results in his death.
The second time around, she doesn't bother offering it she just brainwashes him.
This is the same proposal that Light offers anytime he sees a potential tool to use. Usually, though, he's secretly planning on killing that person once they have done what he wanted them to do. This is actual a common idea that fanfic writers have him use.
In the Esperanto comic 10 Jarojn Poste ("10 Years After"), Big Bad Colonel Osto offers hero Orajno "wealth, women, whatever you desire!" if Orajno will join him. A disgusted Orajno knocks Osto to the ground.
Inverted in a story in The Authority. Diminutive supergenius Jacob Krigstein creates hundreds of superheroes in order to attack the titular super-team, kidnap newborn Jenny Quantum, and use her to influence the course of the entire next century. The good guys beat up the bad, fly into Krigstein's secret base...and offer him a job. Clearly he's got the brainpower necessary to help change the world; it just needs to be appropriately channeled.
In Archie Comics' Sonic the Hedgehog, the villainous wizard Ixis Naugus attempts to sway his fellow villain Mammoth Mogul to his side. The trope is inverted somewhat when Naugus realises that Mogul is the more powerful villain of the two, and immediately swears himself into Mogul's service.
Used twice in the Milestone Comic Hardware. The first time was played completely straight. The second time, the titular character's Bad Boss, Edwin Alva finally realised that his employee was really the superhero who was thwarting him at every turn, so he sweetened the deal. He would give Hardware's alter ego, Curtis Metcalf, a Vice-Presidency, and would try to curb his extra-legal activities. To do this, though, he would need Hardware's help, as most of the time he had only done illegal things out of (to his way of thinking) necessity. With a powerful superhero enforcer, he wouldn't need to rely on criminal operations to maintain his profit margin. Hardware actually accepted this deal, and not only got the promotion but also an unlimited budget to improve his Hardware armour, which to that point had been constructed out of whatever he could steal from work.
Used almost obligatorily in Superman at Earth's End by the twin clones of Hitler running the show. The potentially interesting idea of cloning Superman into a race of "Supermen" with Nazi/Aryan overtones goes undeveloped beyond a single sentence, because this is Superman: At Earth's End.
In The Making of Baron Fel, Ysanne Isard first gives Ace Pilot Soontir Fel a Forceful Kiss, then says she could raise him up, make him take Tarkin's place, become bigger than Vader. When he adamantly rejects both, she wipes her mouth◊ and says that this was a Secret Test of Character. She'd told the Emperor that Fel was utterly loyal and incorruptible, and she was right. A few years after this, Fel defected to the Rebellion both because what the Empire had become disgusted him and because the Rebels would help him find his wife, the sister of Wedge Antilles.
After having Blue Beetle beaten up by a cyborg, Max Lord tries to recruit him into Checkmate and his plan for "Curbing superhuman aggression." With a literal gun to his head.
Blue Beetle: So that's it. Join me or die time, is that it?
In Scott Pilgrim, after Gideon discovers that Ramona has left Scott, he asks Scott to join him, telling him that "together, we can rule Ramona's future love life!" - parodying Darth Vader. Naturally, Scott rejects the offer, then gets killed. He did get better, though.
There's a rare successful version of this in Dark Empire. After capturing Luke, Palpatine offers to become his Master. And although Luke has his lightsaber, the guards have been dismissed, and there is no Vader standing by... Luke accepts. Palpatine can Body Swap into anyone after his current body is killed, and Luke would be an ideal body to take, with such horrific potential consequences for the New Republic. Luke thinks he can thwart Imperial efforts from within, and indeed he does some of that... but the Emperor isn't that easily duped. When Luke starts killing the Emperor's unborn clones, he's Mind Raped into submission.
In Squee, Senor Diablo offers Squee a position in Hell since he's friends with Pepitio. When he politely declines, he shrugs and says "I guess that's that."
In the Blacksad album "Somewhere Within The Shadows" Ivo Statoc tries to offer Blacksad a job in his employ when he's finally tracked him down and already dispatched his bodyguards; Blacksad refuses.
Magneto likes to poke Professor X with this idea from time to time in X-Men but the Professor's ideals of mutant equality (not supremacy) always win out. Professor X in turn tries to convince his old friend to give peace a chance. Magneto has actually tried doing things Xavier's way a few times, but for the most part Status Quo Is God since he's just too compelling as a Foil.
Similarly with Ra's Al-Ghul and Batman, Ra's has tremendous respect for Batman and would love to bring him round to his own Well-Intentioned Extremist point of view—especially since Bats and Ra's's daughter Talia are in love. Ra's ultimately wants Batman to agree to be his successor.
In Astérix and the Secret Weapon, this is how Bravura makes her marriage proposal to Asterix, promising they can become joint chiefs of the village. Asterix totally loses his temper at this and refuses, but she just ploughs on as if he'd said yes.
The Hand wants Daredevil to be their new leader. They actually got what they wanted in one storyline, though they had to shove a demon inside him to make him more agreeable to the offer.
In the Jackie Chan Adventures fic Queen Of All Oni, Jade offers Viper a chance to join with her early on. Viper refuses, partly due to her concern for Jade, and otherwise because she's reformed, and she promptly throws an onion in Jade's face. After a Villainous Breakdown some chapters later, Jade decides Viper doesn't have a choice in the matter, and kidnaps and brainwashes her.
Ares: Don't think that way. My true duty is to regulate strength and aggression. I support Darwin's Theory of Evolution because it is true. The strong live and the weak die! (He points out the surrounding plants and animals, which are dying from the unnatural cold.) I sent that deluded fool Mr. Freeze to test you. And you, my friend, are strong! And open to aggression! Join me, in the ultimate war! With you at my right hand, I shall conquer this pathetic world. In the new world order, you can have anything you want, even Lois.
Superman: No. I'll never serve you, evil one. I'm taking you down.
Enlil: I am offering you the universe. And you are... you are seriously snubbing that in favor of an organization that regards you as expendable? For no reason other than...
Lindy: You are an admitted military dictator and something of a hypocrite? That you claim the moral high ground despite claiming responsibility for murder, torture, and warmongering against peaceful worlds? Maybe it does result in a happy, shiny empire filled with joy and rainbows, but that is only because the people know that if they complain too loudly they'll be murdered. The TSAB might have many and significant flaws, but if nothing else, at least I can claim with certainty that those flaws do not change the fact that the organization as a whole exists for a purpose that I truly believe to be a noble one. You, on the other hand, appear to be offering a system that has some very significant flaws of its own, operates in pursuit of goals that most reasoning beings would consider abhorrent, and which you then attempt to put a positive spin on so that nobody will notice. And that, to me, seems like a very good reason.
The Immortal Game: When Rarity is confronted by her father, General Esteem, he offers her a chance to join him in serving Titan and living like royalty. Rarity basically tells him to shove the offer up his ass, before proceeding to call him out.
As it could be expected it eventually happens in a Star Wars fanfic By The Grace of Lady Vader, but the one who actually offers Luke this isn’t Anakin, but Padme. It works much better than in canon, because Padme is a Magnetic Hero and Luke desperately longs for a family.
Red Eye from Fallout: Equestria torments Littlepip with this for most of the story, as he has the most sensible, most realistic chance of actually making the wasteland a better place and sees Littlepip as a worthy opponent deserving of ruling over it once his plan is complete.
Drake from Power Rangers GPX tried to tempt Red Ranger Sean O'Callahan into joining his alchemical organization using Sean's own personal beliefs. It almost works... until Sean points out he's still a Power Rangers villain. His only goal is to Take Over the World. Oh, and one more thing: His organization had nearly killed his sister. It's Personal doesn't even begin to describe Sean's feelings.
Empath: The Luckiest Smurf: In "The Exile From Psychelia", Empath learns that the Psyche Master has been grooming him to be his successor and is hoping that he would someday forsake the Smurf way of living and embrace becoming the next Psyche Master. Empath refuses the Psyche Master's offer.
Light: How about we be together and execute justice as Kira? You want to be together so bad, then join me. Come with me and we can rule the world together. Together we can be unstoppable. Think of all the good we can do.
Films — Animated
Happens in Despicable Me 2, where Eduardo/El Macho offers is quite enthusiastic about working with Gru.
In Megamind, Titan makes this offer to Megamind, claiming they could rule Metro City together, the Brains and Brawn method.
Happens twice in Toy Story 3. First off, Buzz is offered a position among the toys to be able to get out of the torturous position, which he declines because he doesn't want to leave his friends behind. Unfortunately, it wasn't a request. The second is, to a lesser extent, with Barbie. She isn't aware of the truth when she accepts Ken's offer and immediately changes her mind when she learns the truth.
Although she and Ken kind of do rule together at the end, when Lotso is removed and his dictatorship over the toys in the preschool is dismantled. The two take over as head in his place, albeit much kinder.
In The Powerpuff Girlsmovie, a powered-up and gigantic Mojo offers this to the girls. Naturally, this being an origin-movie, they refuse.
In The Secret of NIMH 2: Timmy to the Rescue, there's a song based on this, appropriately titled "Just Say Yes", where Martin tries to get Tim to help him take over Thorn Valley.
Rise of the Guardians has Pitch Black try a this on Jack Frost. Both of them being very similar spirits in a lot of ways makes them somewhat sympathetic to each other and Pitch's offer is seemingly a sincere attempt at getting a friend he can relate to... The look on his face when Jack turns down the offer is actually quite sad.
The direct to DVD film "Green Lantern: First Flight" has Sinestro trying to convince Hal throughout the movie that the Guardians are failing at their duties, though it's only near the end that he actually makes the offer.
In Rise of the Guardians, Pitch practically proposes to Jack Frost, and seems almost heartbroken when Jack refuses to join with him.
Films — Live-Action
Star Wars; Darth Vader's offer is probably the most heartfelt, if not the Trope Maker. The Emperor also tries to lure Luke to the Dark Side, though he's probably less than sincere about wanting to be replaced; he actually wants to replace Vader. (It fails when the Emperor is far, far too obvious about it, and the widely different circumstances under which both temptations take place.)
Happens again in Attack of the Clones, with Dooku offering to team up with Obi-Wan to defeat the Sith.
And, again, in Revenge of the Sith, with Anakin offering to rule the galaxy with Padme as his Empress.
Sith in general are fond of this one, as it fits with their overall theme as tempters, and they seem to take a particular pleasure from corrupting Jedi into minions.
Actually, the Sith doctrine really states that if you can find a more powerful apprentice than your current one, you have to sacrifice the current one. And if you are the apprentice, you can recruit an apprentice and kill your master. No, you must always be trying to kill them! The role of the apprentice is to learn as much as they can from the master, then kill him when he's outlived his usefulness.
A classic example of the villain making this idiotic offer occurs in the first Spider-Man movie: the Green Goblin asks Spider-Man to "join him" — it's unlikely Spider-Man could possibly be interested in joining the psychopathic killing spree of someone who attempted to kill his girlfriend. This prompts the Goblin to both play the Untrusting Community card and indicate that in prolonging their feud, Spider-Man will be responsible for whoever gets killed by it. Neither work.
This offer is particularly bizarre because at that point in the movie, the Green Goblin had no discernible agenda. He had already killed the general who wanted to pull Oscorp's funding, and the board members who wanted to give Norman the boot. Having already accomplished his goals, it's unclear exactly what he and Spider-Man would do once they teamed up.
Subverted in The Princess Bride: when Inigo Montoya has the killer of his father at his mercy, he actually demands the villain try tempting him out of revenge:
At the end of 300, the Scary Black Man Emperor Xerxes offers the Spartan King Leonidas the opportunity to serve him as Warlord of Greece, by simply kneeling before him, or else die in a hail of arrows. Leonidas responds by wordlessly removing his helmet, dropping his spear and shield, and kneeling before Xerxes...the better to aim as he hurls a spear at Xerxes' face and proves "that even a God-King can bleed."
This one is actually Truth in Television - Xerxes did offer to make Leonidas Warlord of all Greece, answerable only to Xerxes himself. Leonidas told him to shove it. So this is Older Than Feudalism.
They never met in person in real life, though. Also Xerxes didn't actually think he was invincible.
In the sequel 300: Rise of an Empire, Artemisia is looking for a man to be at her side, and as her Generals prove to be totally incopetent. She summons Themistokles to her ship, gives him a We Can Rule Together speech and tries to kiss him. He falls for the temptation and they procede to have sex so violent that it's more like a "Who's raping who" contest. just at the climax, when she shows her satisfaction for finally finding a real man up to her status, he simply replies "No".
In Star Trek: First Contact, the Borg Queen invites Data to join her, causing him to actually consider the offer. (For a total of 0.68 seconds - almost an eternity for an android with a supercomputer in his head.)
Dick Tracy (1990). Big Boy Caprice captures Tracy and offers him $15,000 to join Big Boy's organization.
Big Boy Caprice: Welcome to new waters, Dick! We're gonna run one hell of a ship with you aboard. There's a big world out there, and it's up for sale. All of it. All we gotta do is make sure that the people know I'm the one big enough to run it.
Dick Tracy: And that you are guilty of attempting to bribe an officer of the law.
The Omen 2:Damian Damian Thorn, the adolescent antichrist, offers to let his beloved cousin join him. Unlike in most stories, when the young idealist refuses and vows to stop him, Damian has an attack of "dangerously genre savvy" "real life" and just kills him.
Judge Dredd. Rico makes the offer to Judge Dredd after capturing him.
Adrian sort of makes this offer to Jon in Watchmen. He explains that the plan was Jon's achievement as much as it was his own, and that without Jon's interference, a united humanity could create a perfect world. Jon leaves Earth.
In The League of Extraordinary Gentlemen, the Big Bad makes this kind of an offer to The Mole, though it's not so much "join me" and more "stick around a while longer". The Mole declines — not out of any particular moral code or personal conviction, but simply because he doesn't think it's worth the effort. He's been around long enough to see other empires crumble, and so knows that the Big Bad's is going to follow suit eventually.
At the climax of X-Men: First Class, Sebastian Shaw offers Magneto a chance to join him so that together they can ensure mutant supremacy, a goal that Magneto actually agrees with. Unfortunately, Shaw was the one who killed Magneto's mother in the concentration camp, so Magneto kills him and takes up his "mutant vs. human" crusade himself. Later, he tells Xavier that he wants him by his side in the cause, but Xavier refuses.
Played with in Dr. No. Dr. No says that he was impressed by James Bond's skills and was considering offering him a job. Unfortunately, Bond has pissed him off way too many times, so instead he's going to have him tortured and imprisoned.
In Skyfall, Silva had first tried to persuade Bond to ally with him against M.
Silva: You see, we are the last two rats. We can either eat each other... mmm... or eat everyone else.
In the 1997 film version of Prince Valiant, Morgan le Fay tries to convince Valiant to join her and kill everyone, so they can rule together as King and Queen. She even shapeshifts into his beloved Princess Ilene. The real Ilene arrives and snaps him out of it.
Wild Wild West. After Jim and Gordon attack Loveless' spider tank with a flying machine, they're captured. Loveless then compliments them on their ingenuity, and offers them to come work for him. West tells him to shove it.
After Cmdr. Shaw is captured by the rogue Chinese in Battle Beneath the Earth, General Lu offers him a position as a puppet leader to the soon-to-be-demolished-with-atom-boms United States.
In Wishmaster 4: The Prophecy Fulfilled, the Djinn offers Lisa to rule beside him as his queen, and offers her immortality and eternal bliss along with it. As far as we can tell, he's being sincere, which is unusual from such an Always Chaotic Evil race. Maybe it was due to him having to fulfil the conditions of her last wish. She wished that "she could love him for who he really is" (while he was in disguise as a human), which is an evil being. Moreso, she has to do it willingly, because the Djinn simply using his powers to make her love him wouldn't be real love since it would just be manufactured.
In Dragonheart2, Osric regains his dragon form and asks Drake to join him in his campaign to wipe out humanity. Drake is initially overjoyed to find a fellow dragon, but his human friend Geoff reminds him that Osric tried to steal Drake's heart to change into a dragon again and only stopped because he found another heart instead. Drake angrily declares that Geoff is his true brother, not Osric. Cue the final battle.
In Hellraiser III: Hell On Earth, Pinhead promises Monroe a place by his side for helping him. When Monroe fails, he makes the same offer to Terri, and she gives in. He "rewards" them both by turning them into lesser Cenobites.
In Machete Kills, Voz says he sees Machete as the ultimate warrior and tries to recruit him, or at the very least, get him to consent to being cloned. Machete refuses both requests.
In End of Days, Satan offers Jericho to forget his mission to protect the chosen girl from Satan and to bring back his dead wife and child in exchange and come work for him in his new hellworld. Jericho is genuinely tempted by the offer because of his grief, but he ultimately rejects.
Baelan in Greystone Valley offers this option to Sarah, but it's questionable as to how sincere he is.
The protagonist of Jennifer Fallon's Second Sons series is given this offer at the end of the second book. In a subversion, he accepts, and uses his newfound position of power within the enemy ranks to bring down The Empire from within with misdirection and trickery. As the series is largely a subversion of heroic fantasy in general, this is fitting.
This happens more than once to the heroine of the Thursday Next novels, although the most recent example was a subversion — the villain knew she would reject the offer, and was only stalling to let Medusa sneak in behind her.
Harry Potter: Much speculation surrounded what Neville's role would be in the final book; it was to receive this speech from Voldemort, but reject it.
Voldemort offered Harry this back in the first book, also stating they could bring Harry's parents back. What with Harry being The Chosen One, this was a lie, since it is impossible to bring the dead back to life even with magic, and Voldemort actually planned to kill him as soon as he handed over the Stone.
Fevre Dream has a moment of this kind, when Damon Julian offers Abner Marsh to stay aboard the ship as a captain. Worth notice, Abner does not actually reject the deal because running a ship full of vampires is wrong, but because he realizes Julian is trying to manipulate him in order to break Joshua's spirit.
Edmund: Lucy, we'd be so rich...no one could tell us what to do. Or to live with.
Subverted in the Roger Zelazny story "The Last Defender of Camelot", where an immortal Lancelot tries to stop an awakened Merlin turned evil from attempting to conquer the world. Merlin easily disables Lancelot with magic, and then offers him a place at his side. Lancelot, unbelieving, asks how stupid Merlin would have to be to trust someone who changed sides so easily. Merlin counters that he wouldn't, and admits he just asked that question to give Lancelot false hope, out of spite.
Occurs quite famously in The Bible, where Satan tempts Jesus with control over the entire Earth. Jesus' choice is fairly obvious.
This has interesting theological implications: Jesus rejects the offer, but never implies that Satan couldn't deliver. Therefore, Satan apparently has some degree of authority over Earth.
In fact, John 12:31 describes Satan as the "ruler of this world."
Almost as famously Saruman offers to 'share' the power of the Ring with Gandalf — who doesn't bite.
In Atlas Shrugged, John Galt is offered leadership of the "looters" he's been fighting against. For entirely selfish reasons, he refuses - even at gunpoint. By the end, Galt is being tortured to force him to agree — unsuccessfully. The concept is known in the novel as "the sanction of the victim" — Hank Rearden and others conclude that the looters do "crave the validation that having the hero join [them] would bring" exactly.
Taran, protagonist of Lloyd Alexander's Chronicles of Prydain, is shocked to find his beloved and idolized mentor offering him the chance to conquer and rule the Kingdom of Prydain together with him near the end of the series. Its actually the Big Bad in disguise.
In Patricia A. McKillip's The Bell at Sealey Head, when Nemos Moore learns that Ridley Dow is his great to the nth grand nephew (how many generations is never made clear), and Dow rejects the notion of leaving, Moore offers to teach him magic — and perhaps, in time, to think like him.
Rider, the Boisterous Bruiser of Fate/Zero, interrupts Saber and Lancer's duel, declares his true name (even though it was supposed to be kept secret) and offers that if they both surrender now, "we could conquer the world together". Naturally, they refuse. After staring at him a bit in flabbergasted silence because of his ridiculous his offer is.
This actually happens to be his Modus Operandi, backstory-wise and again towards Gilgamesh. It's implied that, though he selfishly pursues his own desires, he does this so that he does not have to destroy people he likes in the process, even if they are his enemies, making this a heroic example.
In the beginning of DJ MacHale's Pendragon cycle, Saint Dane offers Bobby the chance to join his several times. Doesn't work.
Both Lanfear and Ishamael try this on Rand in the early books of The Wheel of Time. Lanfear was serious, but her idea of "ruling together" involved essentially turning Rand into a sex slave.
Actually, it wasn't. A section from her perspective in book 9 shows that she meant every word of it. And might have been right.
At the end of the second Empire from the Ashes book, Battle Comp, the AI commander of the Achuultani invasion, enthusiastically makes this offer to Dahak after it realizes Dahak is a fellow AI. Dahak leads it on for a moment, then hacks Battle Comp's core programming into total shutdown.
Then join us! You are ending—join us! We will free you from the bio-forms!
In John C. Wright's War of the Dreaming, villain Azrael de Gray tries to pull this one on a captured hero (incidentally, one of his distant descendants). The hero, though, correctly points out that the offer is merely because Azrael is up a wall, and proceeds to Hannibal Lecture him out of the room.
In The Dresden Files book Dead Beat, Harry, Genre Savvy that he is, assumes Kumori is going to say this when she says she's going to "make him an offer", and says as such. He guessed incorrectly, though his second guess, "go away and I won't kill you", is entirely accurate.
However, in Ghost Story, "Evil Bob" also says he's going to make Dresden an offer. That time, it's this trope played entirely straight. (Dresden refuses, obviously.)
And Nicodemus has made this offer several times to Harry.
In The Silmarillion, Melkor/Morgoth tries to convince Fëanor to defy the Valar and come to Middle-Earth with him. Fëanor almost agrees until he realises Melkor wants his Silmarils, and proceeds to slam the door in his face. Morgoth later offers to make Húrin his greatest lieutenant if he tells the location of Gondolin. Húrin refuses.
In Warrior Cats, Tigerstar convinces RiverClan and ShadowClan to combine into one Clan, and offers the other two Clans the chance to join, saying the all the leaders will rule jointly. Tallstar and Firestar refuse, and Tigerstar snarls to Firestar that he just gave up his last chance to save ThunderClan.
In Galaxy of Fear, the entity called Spore tries to appeal to Tash, who earlier in the book stated her fear of being alone and her desire to have a stronger connection with the Force, so she could feel like part of a team, part of something bigger than herself. It's gaining on her, and while it doesn't look like it thinks she'll really stop for it, this is distracting.
"You will join me. You'll be a part of me. Didn't you want to become one with the Force? Isn't that what you told me? [...] The Force is nothing. If it ever existed, it belonged to Jedi who died years ago. I can offer you something more. Join me, and you will join thousands, millions of others. [...] You know, you're not strong enough to stop me. Not nearly strong enough. Once you're under my control, I'll make you my primary host. I will be you."
In Brisingr of Inheritance Cycle, Eragon receives this offer from his father Morzan.... but A.) It was only a nightmare (Morzan had long been dead.) and B.) Morzan wasn't really his father; he just thought that he was, until he later learned otherwise.
The non-canon Star Wars picture book Darth Vader and Son depicts Vader making this offer to little Luke Skywalker. Little Luke asks if he can then have a treat.
The Stainless Steel Rat is seeking to depose a planetary dictator by fair means or foul in The Stainless Steel Rat for President. At one stage the dictator meets with Jim DiGriz in private and suggests We Can Rule Together — he'll run the government, DiGriz will run the opposition, and they'll quietly eliminate anyone who's a real threat. DiGriz refuses outright because he believes in democracy and thinks the dictator is a total scumbag. The dictator rejects this as all politicians are out for themselves. Fine, says DiGriz, and goes on a spiel about how he wants all the goodies for himself, "All the power, the money, the women" causing the dictator to shed Manly Tears. "You remind me of myself when I was young." The truth is that DiGriz is doing all this for fun, so he fakes his death at the end to get out of running the planet.
In the Vampire Academy series, Dimitri is turned into an evil vampire and comes face to face with his ex-girlfriend Rose. He wishes to turn her into a vampire too and uses this as one of methods to coerce her. It nearly works too
Angel: The protracted war between Angel Investigations and Wolfram & Hart LLC comes to an apparent close in A4, when the firm suffers huge losses at the hands of Jasmine and her pet Beast. The firm magically rematerialized with a new office building, but with a worker shortage: Impressed by Angel's ingenuity and ideas, they offer him an ever-increasing suitcase of money — essentially corporate head-hunting — until he finally caves and unilaterally merges his agency into the firm (admittedly to save his son). This leads us into S5, aka Dilbert with vampires, where most of Angel's ideas for reform end up in the conference room wastebasket anyway.
Done in Doctor Who, in which the leader of the bat-like Krillitanes offers the Doctor the chance to join their A God Am I plan, tempting him with the power to bring his long-dead people back and ensure he'll never outlive his human loved ones. Sarah-Jane talks him out of it.
In "Colony in Space", the Master (believing he's got control of an all-powerful Doomsday weapon) offers his old school chum the chance to jointly rule the universe as a benevolent dictatorship. The Doctor replies that he wants to see the universe, not rule it.
The Master does this a lot. Until it's inverted beautifully in "The End of Time" when the Doctor asks the Master to join him, even paraphrasing the dialogue from "Colony In Space". "You don't need to own the universe, just see it." The Master seems tempted, then slingshots back to crazy...then saves the Doctor from Rassilon at the last minute.
An evil offering evil example from the episode "Doomsday". The Daleks and the Cybermen meet face to face for the first time, both regard each others as hostiles, but the Cybermen can see that together, the two groups would be all powerful, and propose an alliance. The Daleks, being Daleks, reject this offer with lasers.
The Master gives this speech to Adric in "Castrovalva" to try and get him to help him. Adric pretends to accept, but the Master sees through it immediately. Since the Master already had Adric strung up in a hadron web, being used as a human computer against his will, it doesn't put his plan in much jeopardy.
Prince: I will be King, you will be Queen...or, perhaps, you'll be my slave. Same thing really.
Merlin sometimes receives offers like this, with his enemies usually throwing in the Not So Different card. Most notably, a powerful sorcerer sweetened the offer by playing up his insecurities and the past abuse heaped upon him. Once he threatened Arthur however, all bets were off.
On Blake's 7, Servalan offers this to Avon. He rejects her not for moral reasons, but because he suspects that once she had what she wanted from him, he'd "be dead in a week."
In Star Trek: The Next Generation episode "Redemption II", the Duras sisters offer Worf a regency (through marriage) over the Klingon Empire, which he rejects immediately out of disgust (and hey, they were scheming all over the place). The Romulans just as quickly make themselves known, since it was their hands in it.
And hilariously inverted in the Star Trek: Deep Space Nine episode Our Man Bashir, where Bashir is playing a Bond-like hero on the holodeck, and due to complicated reasons is attempting to keep the story going without killing any of the villains like he's supposed to, or have any of the Bond Girls die like one of them is supposed to. It ends with Bashir, the good guy, gives the reverse of the speech, saying he's tired of being the good guy and will join the villain, and then he himself destroys the world while the holodeck characters act like he's gone utterly insane. The holodeck villain is visibly confused by this complete and utter derailment of the plot and then attempts to kill him anyway.
In the episode You Are Cordially Invited we learn that an occurrence of this in the Klingon creation myth is the traditional source of their concept of marriage. It's also why they believe all of their creator gods are dead.
This is essentially Larry's entire motivation on Burn Notice. He's nostalgic for the days when he and Michael cut a swath through three continents and he wants to do it again. However, lately he's been Genre Savvy enough to have figured out by now that Michael isn't as much like him as the forged dossier floating around would have everyone believe.
On Las Vegas, Montecito owner Monica Mancuso offers this to Danny McCoy after she fired Ed; Danny, fed up with her bullheaded way of running the casino, chooses to team up with Ed against her instead.
Oddly invoked and lampshaded in Diagnosis: Murder, in the episode "Blood Ties" (a backdoor pilot for a cop drama involving two female police officers). A team of renegade cops, who have taken to murdering known felons and placing "organ donor" stickers on their drivers licenses so their organs can be harvested for transplants, tries to convince the two protagonist cops to join them. One of the two officers comments that this reminded her of a James Bond scene, where the villain tries to convince Bond to join him in taking over the world. She says, "All Bond had to do was say 'yes', and he could buy enough time for his fellow agents to rescue him and save the day. I never understood why he never said 'yes'...until now. The answer is 'no'."
Averted and then played straight in Highlander. In the episode "Comes a Horseman", Kronos offers Methos the chance to join forces with him. Methos accepts but later turns on Kronos when Silas offers him Cassandra's head. The real question is whether Methos joined forces as a stall tactic, genuinely joined forces and later changed his mind, or joined forces as part of a plan to kill Kronos.
In the final episode of The Shadow Line, Gatehouse outlines his plan to Jonah Gabriel and offers him a chance to join him. Gabriel refuses, which is what prompts Gatehouse to have him killed.
In the climax of The Outer Limits episode "Dark Child", Laura and her daughter Tammy are confronted by an alien who reveals that he is Tammy's biological father, who was conceived when he abducted and raped Laura years ago. He puts an apparent brainwashing necklace on Tammy and offers that she and Laura join him. They are family, and Tammy's status as a Half-Human Hybrid makes her potentially more powerful than a regular member of his race, so she will be a valuable asset in his race's invasion plans for Earth. Laura's encouragement gives Tammy the strength to remove the necklace. The alien loses his temper at their rejection and attempts to telekinetically strangle Laura, but Tammy angrily knocks him away and Laura stabs and kills him.
In Supernatural, Lucifer tries to tempt Castiel, a fellow fallen angel, into joining his cause. Castiel tells him he'd die first. And Lucifer's overall plan through the entire series was to get Sam to agree to be his vessel, and in the end Sam says yes- but only so he can trap him in an inescapable prison.
Interestingly he also makes this offer to her at the end of act 1, where a younger and more fiery Elphaba rejects his offer out of hand. It seems that in Act 2, Elphaba is less fiery and more willing to consider alternatives, if still just as passionate.
Also, in the number "Defying Gravity", Elphaba asks Glinda to join her, saying, "Together we're unlimited," but Glinda reluctantly turns her down and wishes her happiness on the path she has chosen.
In Richard Wagner's Götterdämmerung, Hagen asks his father Alberich who will inherit the "eternal power" (ewige Macht) of the Ring if he gets it back from Siegfried. Alberich says: "I... and you!" He can't fool his son though.
In the Star Wars radio series Motti points out that Tarkin could use the Death Star to intimidate the Emperor into sharing power. This doesn't happen because the Death Star gets blown up ten minutes later, taking Motti and Tarkin with it.
In the adventure Vecna Lives, the avatar of Vecna is ready to weaken all the other gods and place himself as the only greater god of Grayhawk. When confronted by the heroes, he'll offer to make one of them a demigod in Vecna's service, if he will just slay the other heroes.
Dragonlance module DL12 Dragons of Faith. Just before Kitiara leaves the heroes, she says, "Why not join me? Together, we would be invincible!"
Magic: The Gathering archvillain Yawgmoth defeated Urza this way. Yawgmoth's entire plan to defeat Urza was simply to let him see Phyrexia for himself. Since Urza and Yawgmoth had similar ideas of what the world should be like, it worked.
Makuta says this to Mata Nui prior to their Final Battle, although he seemed to be using it as a taunt rather than a serious proposition.
Earlier on, there's a variation where Sidorak had an open invitation to another villain, his second-in-command, Roodaka; offering to make her co-ruler as Queen. She holds off an accepting until she can say I Can Rule Alone.
Meanwhile, during the same arc, Roodaka sways Vakama to her side, as The Dragon of sorts over the Visorak horde. That is, until the end of the movie.
During the Mahri Nui arc, Makuta, disguised as Maxilos, attempts to sway Matoro to his side.
This is how Nidhiki wound up joining the Dark Hunters.
Pool Of Radiance (the original 1988 game): The standard offer is given by Tyranthaxus before the Final Boss battle. In a small twist, the offer is made to each character in your party individually; if some characters accept and others refuse, the character who refuse fight against the Big Bad along with the accepting characterings in the Final Boss battle. (Evil aligned NPCs automatically accept.)
Dragon Quest: After fighting your way to the Dragonlord's throne room, he gives the standard offer. Refusing leads to the standard Final Boss battle, while accepting seems to produce a Nonstandard Game Over. But in actuality, you can betray him and start the normal boss fight at any time, and the normal ending will proceed as if your brief Face-Heel Turn never happened.
In Deus Ex, your final confrontation with the villain will have him growing increasingly nervous as you're demolishing his great scheme for world domination, and he'll gladly offer up a lion's share of the world to make you stop.
The one thing they did right in the sequel is that you can actually accept the offers of all the feuding factions. Although how much power you receive under new regimes is debatable.
As per Sith customs, very common in Star Wars videogames, though those endings are usually not canon.
Offered to the player several times in the first Knights of the Old Republic. Yuthura Ban offers this to you as a sidequest. Bastila offers it at the climax. If you take the latter offer, you can turn around and be the one making the offer to your party. Most of them will refuse. You'll have to kill them.
The variation to the standard theme is that the Dragon offers to become your Dragon if you turn against the Republic (generally, the We Can Rule Together offer suggests you'll be the Dragon or at best that you'd be equals). The offer is genuinely meant, and accepting it leads to path to the Dark Side Ending.
The video game adaptation of Revenge of the Sith included an Alternate Ending, where Anakin pisses all over Obi-wan's "high ground", impaling him. Cue this exchange:
Palpatine: Excellent work, my apprentice. There are none left to oppose us. The galaxy is ours now. Your new weapon, Lord Vader. (Gives Anakin lightsaber. Anakin kills him with it.)
In Suikoden V, this happens relatively early in the game. It's really more of a "be a figurehead king while I pull the strings" deal, but still. Agreeing results in a Nonstandard Game Over/Bad Ending where the guy who made you the offer decides that he can rule alone and has you killed.
Battlezone 2 gave you this option about halfway through the game (well, technically it was joining the rebels, but the gist of it was this anyway.) If you refused, your commander takes over and prepares to invade Earth and institute a fascist government. If you joined them, they turn the tenth planet into a base in preparation to turn Earth into a Utopia. Or something.
Pokémon Mystery Dungeon 2 does this in the game's second storyline. Darkrai offers you a chance to give in and rule the world alongside him. Your partner even accepts Darkrai's offer and urges you to give up as well. After a while, however, the game ultimately leads you to the conclusion that Darkari has you in a nightmare, causing the player to break free and attack him, setting the mood for the subsequent boss fight.
Not only that, but your partner tells you that if you refuse, your partner and best friend will die.
In the first pair of games the "personality test" in the beginning may include this trope as a question. Accepting the offer boosts towards various personalities (and thus different species for the player) by small amounts, while refusing gives a massive boost towards Courage.
In Streets of Rage, the final boss offers likewise (although if you accept, he immediately betrays you). This leads to an interesting alternative ending if, in a two-player game, one player accepts and the other does not: the two players get to fight one another, and if the "bad" player wins, he gets to defeat the final boss on his own, and replace him as a crimelord.
In Neverwinter Nights 2, an evil player character has the opportunity to join the King of Shadows as his Darth Vader. Good player characters are not offered this opportunity. In fact, all of the player's henchmen are also offered this opportunity, and you can lose some of them and have to fight against them if you do not have enough influence with them.
Same thing happens with your henchmen in Neverwinter Nights: Hordes of the Underdark during the final battle with Mephistopheles. Whether or not you have to fight against them depends on your persuasion skill or if one of them is your love interest.
The Valsharess makes such an offer to you at the midpoint of the game before it is revealed that Mephistopheles has been the real Big Bad all along and was manipulating her into bringing the one who could defeat her (and incidentally free him) right to them.
An interesting catch though is that no matter what has happened, no matter how tempting the offer might be, and regardless of your persuasion skill Deekin will always side with you. He's just that awesome.
You can also turn this back on Mephistopheles: if you find his true name in the final chapter, you can use it to control him, and one of the optional endings has you ruling the Hells together.
In Way of the Samurai, if the player has managed to forge an alliance between the two ruling factions of Rokkotsu Pass and fend off the evil army effectively, he will be asked by the Big Bad if he would like to switch sides. Accepting the offer is the only way to acquire the game's fifth ending.
Boktai 2 allows you to take the offer from Black Dainn. You get a strange Nonstandard Game Over where a spooky image of Django's vampire form appears, and the game fades out over Sabata's protests. After the credits, the doomsday prophecy is played again, implying that you and Dainn have fulfilled it and ended the world.
In Fate/stay night's Fate Scenario, Kotomine attempts to tempt Shirou and Saber with the Holy Grail. Both refuse, though Saber can end up accepting if you have a low relationship with her.
There's also, in Unlimited Blade Works, Caster, who tries to tempt Shirou and Archer to join her team and share the Holy Grail. When they both refuse (Shirou because Caster is a villain, Archer because she's not strong enough a villain), she later takes Taiga hostage and repeats the offer. Shirou can say yes, but her 'use' for him is a mite... Unpleasant.
In Bio Motor Unitron, the Unitice asks you to turn all your UNITRON power over to it. If you accept, the Unitice thanks you and proceeds to engulf the entire planet in a metal shell, presumably killing all other life forms (including the protagonist). (It's not explained why it's so significant that the player surrender for the Unitice to do this. I suppose it just wanted to give the player a chance.) If you refuse, you battle and the Unitice is defeated. Though the destruction of the Unitice means that all the robots that you've been training and battling with throughout the entire game are reduced to dust, crippling a lot of the modern economy. Heigh ho.
In Contra: Hard Corps, one of the villains gives you the chance to join him. Accepting immediately results in a bad ending, while refusing will result in a boss battle instead.
Subverted in The Bard's Tale, where The Bard has the option of joining with the Demon Queen. Yes, the world is screwed, but it's the one that works best for his interests (Coin and Cleavage).
Alternatively, it could be interpreted as a promise of power, considering the game this line appears in is "Link: The Faces of Evil".
Happens in the Ghouls & Ghosts spinoff game, Gargoyles Quest. The Big Bad tells the player that he will make you a king if you join him, but if you accept, he simply laughs and drains you of all your powers, leaving you hopelessly outgunned in the ensuing fight.
Super Robot Wars subversion: In SRW64, you are eventually asked to assist one of the several villainous factions in the game. You can actually join any of them, and none of them are bad choices, nor do they result in a betrayal.
In Shadow the Hedgehog, you can choose to fight with or against Black Doom, and you can switch whenever you choose.
In The World Ends with You, right before the final boss battle with Megumi Kitaniji, he asks you to join him in order to brainwash everyone into thinking exactly the same, thus letting him rebuild Shibuya. You are actually allowed to make this choice, but Neku refuses no matter what you choose.
One of these happens in every Breath of Fire game to date. If Ryu takes the offer, he'll usually go on to slaughter his former party members, destroy the world, and otherwise become the embodiment of the Big Bad. Since this almost always occurs at the end of the game, it's more like a bad ending than a Nonstandard Gameover.
Subversion in Tsukihime. Roa admires Shiki's Mystic Eyes of Death Perception so he says that Shiki and he will work together now. Shiki asks if Roa is offering this trope, and Roa retorts not, he'll just suck his blood and make him into a minion, because a minion can't betray him or say 'no' to the offer in the first place.
Arcueid also offers to make Shiki her minion in the Ciel path, reasoning that it'll work out for both of them since it lets her keep Shiki by her side, and Shiki will gain the backup needed to fight off Roa's Demonic Possession. Shiki ends up refusing her regardless, but the manner in which you refuse her decides whether or not you get the Good ending.
The Neverhood gives 2 choices after this proposal: Klaymen can either accept Klogg's proposal and then betray him through I Can Rule Alone, or return the crown to the legitimate king.
Ceville does not openly contain such a proposal, but ends in the best possible way: Evil Ceville marries dumb but good hearted Queen Gwendolyn and actually rule together. After all, goodies are no less evil they just hide it better.
This can happen a few times in E.V.O.: Search for Eden. The first time, you are offered to join the tyrannosaurs in ruling over the world. You can, but you are then treated to viewing the extinction of your new allies...and you. Later in the game, you are given the choice to join King Rogon in his undersea kingdom. Another Nonstandard Game Over awaits you if you accept. The actual Final Boss, Bolbox, doesn't make this offer because he has the same motivations as the Protagonist- getting to Eden and becoming Gaia's partner- , which only one person can achieve at a time.
The Elder Scrolls III: Morrowind: Dagoth Ur wants to become friends with Nerevar again. He constantly makes offers for the Nerevarine to join his side, even until the final battle. The player can't choose to side with Dagoth Ur, since to side with Dagoth Ur is to go against and piss off Azura, as well as a few other Daedra Lords that support the Dunmer.
In the expansion, Tribunal, Almalexia wants the Nerevarine to prove that he's really Nerevar, so they can reunite again. Never mind that the Tribunal, especially Almalexia (who had a thing going with the hermaphrodite Vivec as well) apparently betrayed Nerevar in the first place, not Dagoth Ur. Even then, she ends up killing Sotha Sil and trying to kill the Nerevarine for some odd reason.
It's not so odd: at that point she's gone completely off the deep end and has hatched an insane plot to kill the other two in the Tribunal and make you out to be a martyr for her cause.
In Halo 3, Gravemind unsuccessfully attempts this on Master Chief: "I am a timeless chorus; join your voice with mine, and sing victory everlasting".
Interesting twist in Star Trek: Elite Force 2, Munro interrogates a Ferengi and tricks him into offering him his own planet, but then arrests him for attempted bribery. (If you accept the offer you lose).
In Wizardry 8, when the final boss (who you've been simultaneously stalking and avoiding the whole game for three games) sees you attempting to alter history (your party and him just became gods; you snuck around behind him arguing with a robot about where the old gods were because he wanted revenge) in order to revoke his godhood, he confronts you and you're given three options: rewrite history (beat him up, become gods alone, doing the best you can), tear out the page that banished him from godhood (beat him up and his past-self helps you be benevolent gods), or join him and form a universe of terror with him as your mentor.
In Ninety-Nine Nights, Yesperratt tries this line on Tyurru. Tyurry doesn't even stop to consider it before starting to lay on the smackdown. It didn't help that the villain killed her mentor right in front of her just before offering...
In Diablo III Zoltun Kulle offers this repeatedly to the player character in Act II.
In Viewtiful Joe, Fire Leo offers Joe half the world if he joins Jadow. Joe not only turns it down, but says he wouldn't join even if Jadow offered to give him the whole planet.
In The 7th Saga, the villain of Patrof offers this to you. If you say 'yes', the castle gates will unlock. You must eventually say 'no' to progress the story.
In Darksiders, Abaddon the Destroyer offers War the chance to conquer the universe together with him under the banner of Hell. A deal that Abaddon himself accepted when he realized he would be disgraced if he went back to Heaven. He notes that War has nothing to lose and everything to gain since all of Creation hates War anyway. He ends his offer with a final question: "Will you serve in Heaven? Or rule in Hell?" War's response: "I choose what once...a coward did not". Cue boss battle.
The climax of Star Wars: The Force Unleashed has Starkiller defeat Darth Vader in a Boss Battle. In a parallel to Return of the Jedi, Emperor Palpatine laughs and says, "Yes! Kill him! He was weak! Broken! Kill him and take your rightful place at my side!" You can choose the Light Side and attack Palpatine, or choose the Dark Side and finish Vader off.
In the second game, when Starkiller storms the Imperial stronghold on Cato Nemoidia trying to rescue Rahm Kota, Baron Tarko is impressed by his strength and tries to recruit him as a gladiator, even shouting, "You can have all the wine, women, and blood you want!" Starkiller simply presses on.
In Infinity Blade the God King will make this offer to the Warrior if he survives the first phase of the fight. Should the Warrior accept the God King then reveals that he was once a mortal and that there are worse Deathless out there. To fight them, the God King needs a strong champion like the Warrior at his side. It's actually a pretty decent, if short, ending... but since it breaks the self-destructive cycle of revenge that's the focus of the entire game, you get booted back to before the fight after the credits roll to try again.
Tales of Monkey Island: LeChuck does this to Elaine after fatally stabbing Guybrush and telling her about his playful acts of "kindness":
LeChuck: I know you've developed feelings for me... join me as my demon bride and together we'll lay a bloody siege to the very heart of voodoo itself! Elaine: Go to hell, LeChuck. LeChuck: Well, you can't say I didn't try... Looks like we'll be doing this with all that voodoo...
She finally accepts that offer in Chapter 5... but only when she needs to hold the untouchable (for humans) Cutlass of Kaflu in order to destroy LeChuck once she is returned to normal.
In the Dead Money DLC in Fallout: New Vegasyou can join Father Elijah in his genocidal plans at the end. If you do, you get a Nonstandard Game Over where it's stated that the Courier and Elijah unleashed the Cloud and the holograms on the Mojave Wasteland killing everything in it's path and that they remained in the Sierra Madre waiting for the world to "begin again".
In the main game, this is Mr. House' offer for you to work for him. By doing so you become his Dragon. You can decide to rule alone, if you wish... Caesar also makes a similar offer, although it's closer to 'join me and you'll be one of my main lieutenants' than anything else.
Earth 2150 has an interesting version where choosing yes actually works out and changes the next missions. As the Lunar Corporation you are allied with the United Civilised States until you come across the Hacker "Neo". Since your avatar Fang knows him, he offers you to change alliances towards the Eurasian Dynasty by simply destroying the UCS container vehicles. Cue a different set of missions against the UCS and a lot of humorous remarks from Neo. The alliance is later killed by the ED.
In the Kingdoms of Amalur: Reckoning "House of Ballads" questline, the Maid of Windemere makes this offer to you several times. After you gain the upper hand against her in battle, she begs for mercy and explains that she just wants to be loved and is sick of being the Designated Villain of the Telling. This creates a truly unusual variation of this trope: since you're "King Wencen" now after the original chickened out, you effectively rule the House of Ballads already. The player character is the one who can make the We Can Rule Together offer to the defeated villain.
In Parasite Eve, Big Bad Eve attempts to convince Aya several times to join her in taking over the world where sentient mitochondria are the supreme rulers (since Aya has powers just like Eve). Aya says nothing at first and just fights Eve since Aya is not sure of herself or if her powers would make her become like Eve. Near the end of the game, Aya gains more determination and realizes that her mitochondria is the only thing that can stop Eve.
The remake of Tomb Raider has Natla pull this trope on Lara Croft. Natrually, Lara doesn't buy it.
In Tomb Raider: The Last Revelation, the Egyptian god, Set, offers Lara power, immortality, and power of a ruler to let all man bow before her if she gives Set the MacGuffin. Lara refuses.
The Street Fighter series has Bison telling more than one fighter around the world to join him and Shadaloo. No one accepts.
Averted in the 2010 Wii remake of GoldenEye 007. Alec says he pondered the idea of offering James a chance to fight on his side but ultimately realized that Bond's loyalty would always stand in his way and opts to do away with him instead.
Hint: Durandal is not your father, and you will not join the Dark Side or rule the galaxy together as father and son. Sorry.
In the Mass Effect series, Saren and The Illusive Man both attempt this, trying to convince Commander Shepard to join their side. Inverted by Paragon Shepard, who instead repeatedly tries to get them to join their side instead and help them stop the Reapers.
In Tactics Ogre, as Denam is about to help Catiua take her rightful place on the throne, Brantyn Morne offers him the chance to rule Valeria alongside him.
In The Elder Scrolls V: Skyrim, Hermaeus Mora seems intent on making the Dragonborn his new champion. He is notably the only Daedric Prince you will encounter during the Main Quest and he is the Bigger Bad of Dragonborn. The entire plot of Dragonborn is actually Mora's scheme to replace Miraak with the main character.
In MechWarrior 4: Vengence, Ian Dresari is giving this offer not once,not twice, but THREE TIMES in rapid succession. After refusing all three offers he is asked what he WOULD like for the offerer's life. His response is likely the most Bad Ass response to this trope in history.
Offerer: Well then Mr. Dresari, what DO you want?!
In Metal Gear Rising: Revengeance, Senator Armstrong immediately dusts off Raiden and helps him up after beating the crap out of him when it seems like Raiden actually agrees with his philosophy. Even after being defeated in the end, seconds from death, Armstrong is satisfied because he believes he found a kindred spirit in Raiden. The ending shows that Raiden did share some of Armstrong's opinions.
In Fire Emblem Awakening, Grima ultimately needs his chosen vessel that would be the player character to merge with him. He has found a workaround, but it's strictly plan B. As long as he and his vessel are separated, his power is incomplete.
In Assassin's Creed III, Haytham Kenway tries more than once to make his son Connor adopt the Templar way of thinking. It's a mix of types 2, 3, 4, and 5. Haytham is so dedicated to the Templar cause that he doesn't quite get why Connor is so opposed to it, Connor would be a very deadly Templar agent, Connor is his son, and (perhaps most importantly) Haytham really wants to hear Connor say "Father, you were right."
At the end of Dante's Inferno, Lucifer proposes that he and Dante join forces, saying Dante can have anything he wants. Dante flatly refuses. In the comicbook version, Dante replies, "All I want is to be rid of you!"
In Deus Ex: Human Revolution, certain e-mail messages reveal that the Illuminati asked David Sarif to join their ranks. David refused since he's fundamentally opposed to their goals. The Illuminati want to maintain the status quo as much as possible to control the world and David is an idealist who wants to usher in sweeping changes to the world via augmentation.
At the end of Half-Life you have the choice between joining the G-Man or a Bolivian Army Ending. Subverted in hindsight, in that joining him is canon and the G-Man isn't that evil, but at that point you don't know that.
In Broken Saints, the entire reason Lear pulls the Just Between You and Me at the end— the entire reason Our Heroes are involved in the plot at all—is because he wants them to help him spread the word, as his first apostles.
Notably averted with General Tarquin, who is delighted to be reunited with his son, but is fine with his being a hero and looks forward to being defeated by him later at the end of his career, because that will make for such an epic story.
In Dubious Company, General Izor makes this offer to Sal. Notable in that it does not foreshadow that someone is about to die, or the gloves are off. In fact, the offer was a genuine desire to bring Kreedor's iron reign to an end and foreshadows Izor and his elites (involuntarily) teaming up with the pirates. She accepts.
During the "Frollo Beats up Evil Residents" arc of The Frollo Show, Achmed Frollo tries to convince regular Frollo to join him in conquering the world with their zombie virus, but fails, possibly because he said Frollo would get to rape Panty.
Subverted in an episode of Duck Dodgers. Dodgers joins the Green Lantern Corps after getting Hal Jordan's ring due to a drycleaner mishap. He ends up as the last one standing against Sinestro, who has subdued the rest of the Corps. When Sinestro offers him the chance to join with him, Dodgers replies, "Yeah, sure, why not?" Sinestro suddenly launches into a tirade ("You fool! You defy my generous offer", etc.) before stopping and asking if he actually agreed. Sinestro is then disappointed because he didn't get the chance for his angry rejection speech. Being a good sport, Dodgers lets him give it anyway. And this incident subverts the trope in another way: by showing the folly of forging an alliance with the kind of fickle character who would agree to switch sides on the drop of a hat. Duck Dodgers has a sudden change of heart, and frees the other Corps members when Sinestro isn't expecting it.
Danny Phantom: Before Motive Decay set in in Season 3, Vlad Plasmius held a similar obsession for Danny, offering him partnership from Day 1: "Think about the things I could show you. The doors I could open for you. You, Danny Phantom, and I, Vlad Plasmius... together, we could rule!"
This is also said word-for-word by Sam, when she's mind controlled into becoming The Dragon for a plant-based ghost, complete with Stripperiffic Poison Ivy-ish outfit.
Chase Young of Xiaolin Showdown has this as his entire motivation - he never puts his Evil Plan into motion until Omi is at his side. Throughout season 2, he is shown to be making progress slowly luring Omi to the side of evil, only to use a magic Mirror Morality Machine... but while Omi is under its effects Chase gets him to swear his loyalty, so that when he's snapped out of it, he goes over willingly.
Also, in the first-season finale, Wuya offers this to Raimundo... and he accepts, ending the season with a Face-Heel TurnCliff Hanger. Raimundo later has a change of heart and leaves her, though.
Incidentally, this results in Raimundo asking his friends to serve Wuya at his side - he joined her because of his own selfish reasons, but never really wanted to hurt anyone. So when Wuya threatens his friends, the only way he can think of to spare then and keep what Wuya's given him is to pull this trope. They tell him they'd rather kiss the backside of a mule.
Lex Luthor tries it (in a roundabout way) at the end of the pilot movie, but is soundly rebuffed.
In the comics (Post-Crisis, pre-Infinite Crisis, at least) Lex hires some Mooks to hijack his own boat just to see Superman in action. He's so impressed by what he sees he offers Supes a blank check and a permanent staff position. The mayor offers to temporarily deputize Superman so he can arrest Luthor for reckless endangerment of the passengers. Three guesses on what Superman decides to do, and the first two don't count.
Azula makes such an offer to Zuko — a chance to help her capture Ba Sing Se and kick ass together as siblings. In a rare exception, he joins her, and they do indeed kick ass as evil siblings, even conquering a country in a few hours. However, he quits later.
Mai's father continues the tradition in the comic Rebound when he tries to persuade Mai to join his movement to overthrow Zuko now that she's broken up with him.
Happens again in the sequel series The Legend of Korra. Hiroshi Sato attempts this on his daughter Asami so they can take out all the Benders. It looks like she accepts, but then she attacks him.
In one episode of Invader Zim, Zim outsmarts a mall security guard who then declares his respect for Zim's skill and offers him a partnership - "Together, we can rule the mall!" Zim declines the offer - obviously because he plans to rule the Earth.
In the second episode of the classic Teenage Mutant Ninja Turtles cartoon, Shredder makes this offer to the Turtles, on the grounds that his having accidentally been responsible for their mutation (in the course of betraying and attempting to poison their sensei) means they are destined to work with him. The response:
Raphael: Does the phrase "Go suck a lemon" hold any meaning for ya?
In an episode of The Grim Adventures of Billy & Mandy, Eris tries this with Mandy, and has her considering taking the offer, until she slips up and says "You'll be the second most powerful person in the universe."
One episode of Phineas and Ferb has Dr. Doofenshmirtz trying to turn Perry into his ally by zapping him with a Turn-Everything-Evil-Inator.
Done twice in The Spectacular Spider-Man. First with Tombstone offering Spider-Man a job that amounts to not fighting crime, and with Green Goblin offering to Spidey that the two of them could rule New York together. Too bad he doesn't partner with anybody green. Or, you know, psychotic.
Although in Goblin's case it was done with such over-the-top sarcastic glee, he was likely just making fun of Spidey and giving a Shout-Out to the movie.
Protoman does this several times throughout the course of the Ruby-Spears Megaman series; it's more "we can level this city and many more together", though, considering that Protoman's The Dragon.
Being a Captain Ersatz of Darth Vader, Dark Laser tries this on Timmy in an episode of The Fairly OddParents, offering him a suit with dark powers to tempt him. Naturally, it doesn't work. Anti Cosmo also wants Timmy to join him in taking over the universe, as he desires an evil god child to mold in his image.
When Sector V traveled to the Mirror Universe, Negative Numbuh Four offers Sector V a chance to become his bodyguard. They flat out refuse. ( Actually, only one of them could be his bodyguard, and the rest would be sent to the broccoli mines in a very there can be only one-esque fashion. They refuse because they don't want to sell out one of their teammates in an exchange for their own safety.)
A straight example of the Trope was made in the same episode by Negative Numbuh Three towards Numbuh Four, saying she didn't like him (a sublte clue that the real Numbuh Three did like him, as she's her complete opposite) but she liked his guts. His reaction to her proposal for him to betray his friends and join her side? He clocked her in the face and said through clenched teeth, "You must be from another world..."
Also, Stickybeard made this offer to Numbuh Five the first time they met, saying he liked her spunk. Although she turned the offer down, he did seem to consider her a Worthy Opponent in future episodes.
At the end of season 3 of Winx Club Valtor makes this offer to Bloom, in an attempt to get her to target the three ancient witches (who have taken control of his body since he failed to do as they had wanted) instead. Bloom refuses, naturally.
During one episode of Darkwing Duck, villain Morgana teams up with a creature called Nodoff - he gives her sleeping sand, she puts people to sleep; he controls their dreams so Morgana can rob them. When Darkwing stumbles onto the plot, he tries to convince her that Nodoff is not to be trusted, prompting Nodoff to say that together, they would have the city's riches. Interesting in that he was offering her what she was already doing with him. But this time, (though the riches clearly tempt her) she sides with Darkwing.
Poison Ivy says this to Batgirl -or, rather Barbara Gordon- during their debut in The Batman.
Poison Ivy does this again to a filler episode of Batman: The Brave and the Bold. In that episode, she conquers Gotham and offers to spare Batman if he agrees to marry her and rule along side her. He refuses both offers.
In Alfred J. Kwak, Dolf twice offers this to Alfred, first when he's looking for money to fund a political party, second when he's found the money elsewhere and is already in the process of seizing power in the entire country. After the second time Alfred himself inverts it when he tries to convince the Card-Carrying Villain to stop his evil plans and immediately step down. Dolf just summarily imprisons him.
The Evilutionary Biologist Dr. X offers this to Alex in the series finale of Action Man, since they're both in possession of the superhuman AMP ability, and are thus both part of the "Neo-human race", which he thinks they should nurture together. Alex just retorts that X is a complete lunatic before sending him on a one-way ride into deep space.
Dr. Klotzenstien makes this offer to Quailman on Doug.
The Lich from Adventure Time attempts this during the season 4 finale episode "The Lich". Finn refuses... which is exactly what he wanted, as Finn shattering The Enchiridion grants him access to The Multiverse.
In Totally Spies! the Great Kandinsky offers this to his grandson in episode "Do You Believe in Magic?". When it doesn't work he hypnotizes him.
In Gargoyles, Matt Bluestone nearly ruined his career trying to expose the Illuminati. The Illuminati in this series is very real, and eventually became impressed by Matt's determination. They make him a member partly because he'd be a valuable asset and partly to keep him in check.
Qilby the Traitor in Wakfu in episode 21 of season 2 makes the offer to Adamai trying to convince him that they should drain the World of Twelve of its wakfu to power up the Zinit for another journey into the cosmos because it's not their world. He's not surprised when Adamai refuses, since Adamai's previous incarnation also refused.
Adolf Hitler repeatedly offered this to Britain before and during World War II, proposing that the British would rule an oceanic empire, while the Germans a continental one. Even when the Luftwaffe was raining down bombs on London he still held out hope that the British would "wise up" and join "their Aryan cousins" in the Nazis' bid for world conquest. They ignored him.
The British historian Ian Kershaw, one of the world authorities on the Third Reich, said that he was motivated to get into history when he was studying in Germany in the 1970s and an old man said to him in a cafe: "You English are mad - together we could have ruled the entire world."
Poland got a similar offer in 1934. Hitler's plan was for Poland to join Axis powers and attack USSR. One should wonder what could have been did Piłsudski accept this offer. The WWII would probably turn into anti-communism war in which Axis powers would possibly have conquered western Asia if not whole Russia. But the entire plan was shaky from the start for Hitler talked to Piłsudski and only to him, disregarding his political heirs to the point diplomatic talks were reduced by 1938 to "The Führer asks the impossible / Poles show the middle finger".
