This Trope is under discussion at the Trope Repair Shop.
Mr. Croup turned out the lights. "Oh, Mister Vandemar," he said, enjoying the sound of the words, as he enjoyed the sound of all words, "if you cut us, do we not bleed?"
Mr. Vandemar pondered this for a moment, in the dark. Then he said, with perfect accuracy, "No."
"Do you think we should explicate ourselves, Mister Rope?"
"May I continue with the expositionizing, Mister Rope?"
"You certainly may, Mister Liche."
"I believe you mean contractors, Mister Liche."
"That I did, Mister Rope, thank you. Now, because of our potential, many writers use us in various forms. Don't they, Mister Rope?"
"They do indeed, Mister Liche, they do indeed. In fact, that's why we're here, because so many writers like to use us and our penchant for exposition and execution."
"And because of our killing people, right, Mister Rope?"
"That's right, Mister Liche. I believe that's all, reader. Anything you want to add, Mister Liche?"
"No, Mister Rope, I never did like maths. Sleep tight, reader."
"Yes, reader, sleep tight."
Those Two Bad Guys are a pair of bad guys who not only provide bloodshed, but also exposition in the form of conversation between them; not to be confused with Those Two Guys, though the two aren't mutually exclusive. They are usually foils for each other; commonly Brains and Brawn, and sometimes Red Oni, Blue Oni. They probably also look different, in such ways as Fat and Skinny or Salt and Pepper. When they show up in a video game, you can usually count on the player facing them as a Dual Boss at some point. Can also be a Big Bad Duumvirate.

- Dungeon Keeper Ami gives us the indominable Mukrezar, and his ever-attentive Imp Butler. Their subplot mostly involves Mukrezar comeing up with zany schemes that are as improbable as a pretty elf with long, luscious, lovely pink locks trying to brutally murder everyone and everything in sight (in an awesome manner). Oh, wait...
- Bachiko and Meiko in Perfection is Overrated, although their status as "bad guys" is not initially apparent. They're also the only two SUEs who can actually work together, and because they are each other's most important people, they die when their Childs are destroyed.
- Friendship Is Magical Girls has Snips and Snails serving in this capacity to Sunset Shimmer for the first half of the Magic Arc. Then Snips is killed by Spike in an Unstoppable Rage for shooting Twilight, and Sunset sacrifices Snails to Chrysalis to appease her. This leads to Snails becoming Eskarrg, Chrysalis' Dragon, in the Loyalty Arc.
- In Harry Potter and the Methods of Rationality, Crabbe and Goyle are faithfully following minions clichés and call each other "Mr. Crabbe" and "Mr. Goyle".
- When Cat R. Waul and Professor Ratigan ally with each other in Olivia Goes West, their respective sidekicks, Chula and Fidget, often work together in carrying out their bosses' orders.
- Out of the Corner of the Eye has Francis White and Ephraim Waite serve as this among the Mythos cultists.
- In Equestria Divided Trixie is The Inquisitor General and Snips and Snails are her lackies.
- Rosario Vampire: Brightest Darkness: Akua and Kahlua serve as such during Acts II and III, being Kiria's Co-Dragons in Fairy Tale. When Moka realizes in chapter 42 that Akua has been working for Fairy Tale all along, Kokoa instantly deduces that Kahlua is part of the organization as well because "that damned brat never leaves [Akua's] side for anything."
- Persona: The Sougawa Files has Nobuyuki Itou and Yuudai Honda, who even get little segments at the end of chapters where they provide exposition on the Shadow Syndicate. They never actually work together in combat due to Yuudai being more of an Evil Genius, but they still share the core dynamic.
- Bud and Buzz from No Good Gofers.
- Edge and Christian used to do this routine back in their days as a tag team. Most notably, during their time in the Team RECK stable, where they'd discuss Kurt Angle's current scheme and provide exposition on what was bothering Angle that day.
- The "Chicago Girls", Nikki St. John and Taylor Made, served as such for Melanie Cruise. One liners and banter among themselves they did well; trying to have the latter cut lone promos turned out to be a disaster.
- As of V4, Survival of the Fittest has Richards and Baines. Although the terrorists are often used as vehicles for exposition, it tends to be this pairing more than any others, particularly given their penchant for not keeping secrets too well.
- In the prologue to the Scion sourcebook Hero, Hugin and Munin, Odin's two talking ravens, behave this way. Although they're not so much "bad" as they are not very nice at all.
- The Fox and the Cat in the opera The Adventures of Pinocchio definitely qualify. Although a bit bumbling, and definitely comedic, their scenes can be intensely creepy. And also a bit something else. They might not kill anyone outright, as they're rather poor at their jobs and more tricksters than assassins, but they certainly make a good try at it. (Such as trying to lynch Pinocchio for the five gold coins he got out of sympathy from the puppet show owner.)
- Rosencrantz and Guildenstern of Hamlet and Rosencrantz and Guildenstern Are Dead fame counted — they might not be straight up villains in Hamlet but they definitely qualify.
- A few William Shakespeare cases, especially the two killers sent after Clarence in Richard III, and Chiron and Demetrius in Titus Andronicus.
- The Dumb Waiter is all about Those Two Bad Guys.
- The First Man and Second Man from Kiss Me, Kate don't kill anyone on stage, but they are mobsters and they talk an awful lot.
- Kurt Weill's opera Die Bürgschaft has a recurring trio of nameless villains who adopt New Jobs As The Plot Demands, ranging from conspiring against Mattes and Orth to doing dirty work for them.
- Goldberg and McCann in The Birthday Party.
- Jessie and James in Pokémon Live!.
- Broken Saints has two pairs: Sociopathic Soldiers Lt. Charles and Lt. Bravado, and strip club bouncers Phobos and Deimos. Also, all four of them could qualify as Giant Mooks.
- Bowser's Kingdom has Hal and Jeff.
- DSBT InsaniT: Michael and Ashley. Both of them are out to destroy technology, but they both are each others weakness.
- RWBY: Emerald and Mercury are Vitriolic Best Buds who work under Cinder and complete missions as partners, with Mercury being the muscle and Emerald being the manipulator. They are introduced light-heartedly teasing each other before murdering a man in cold blood, and later joking about him.
- The Walten Files: Bon the Rabbit and Sha the Sheep. If one is present, the other usually is as well. Considering that the people possessing them are husband and wife, respectively, it makes sense that the two would appear together quite often.
- Dom and Ed from MegaTokyo, though they are enemies.
- The Caterers of Calumny, Texto Porfiria and Zuzux Uzbochs, in Unicorn Jelly. Their favorite modus operandi is rather unusual — they pose as caterers and serve poisoned food.
- Hunter and Arcturus from Suicide for Hire are a Villain Protagonist variation.
- The reptilian bounty hunters Gannji and Enor from The Order of the Stick when they count as Punch Clock Villains.
- The two robbers in one of the earlier Girly arcs. Arguably, the two-headed turtle may fit in this category as well.
- The Inexplicable Adventures of Bob!:
- The recurring Men in Black, Agent Ben and Agent Jerry. They're Lawful Stupid rather than evil, but they still always function as antagonists. Ben's the tall, thin, laid back one. Jerry's the short, fat, grouchy one. They tend to get mistaken for The Blues Brothers.
- They haven't shown up as often, but there's also the Rogue Canadian Scientists, and the Pirates of Ipecac. Both pairs have been seen most recently working for Bigger Bads.
- Up until the latter's HeelFace Turn, Stunt and Bumper were very much this for Dominic Deegan.
- Boulet Corp: In "Pizza Mafia", Boulet recounts a sighting of what he suspects was a real-life example of such a pair.
- Homestuck: Lord English's dimwit minions Eggs and Biscuits are hardly seen without each other. Probably because they can combine their abilities to make infinite copies of themselves.
