The underling who's much smarter, more efficient and more industrious than their (usually totally incompetent) boss, and is the one actually responsible for anything that gets done in the workplace. Despite the fact that they work their butt off for little pay and no credit, this person is generally pretty happy with the way things are. If they or the incompetent boss aren't the lead character, they'll often use their skills and position in order to help the lead character out. If their incompetent boss is the Big Bad, they're the right hand and act in the opposite manner to The Starscream even though they may have plenty of motivation to be one. They are often known for appearing right before they are called, always with whatever they were going to be asked to bring.
The greatest danger to the Hyper-Competent Sidekick is having a boss who is too stupid. Witness the relationship between Blackadder and Prince George in the third series of that show. The Prince is easily manipulated, but his sheer idiocy is forever landing himself and his butler into incredibly dangerous or difficult situations.
When the Hyper-Competent Sidekick wields more actual power than his or her boss, it's an Almighty Janitor. If The Dragon is a Hyper-Competent Sidekick who is more of a threat than the actual Big Bad and has little, if any respect for the boss, then he's the Dragon-in-Chief.
When the boss is competent in his own right and/or when the sidekick actually enjoys being the underling, it's a Chessmaster Sidekick.
This trope often walks hand in hand with The Creon, to explain why the character doesn't move up in the organization.
A character that would rather not be in this position is the Beleaguered Assistant (though there's probably some overlap).

- The 2017 UFO Kamen Yakisoban commercials ostensibly star new hero Sauce, but all he does is get beat up and captured. His partner, the Legend, can turn into a motorcycle, a tank, and take on the Demon King via the power of judo throws.
- Make a Wish gives us Henchgirl, who works 'for' the Professor. (They actually both have doctorates; they flipped a coin to see who would be the Professor and who would be the henchman, because in their view someone has to be the henchman.)
- Subverted in the Deliver Us From Evil Series. Davy Wiggins is the Hyper-Competent Sidekick of an equally Hyper Competent Hero, Sherlock Holmes. Later on in the stories, Wiggins is the Hyper-Competent Sidekick to Dr. Watson - the two men are shown to be equally clever.
- Played with in another Sherlockian example, A Study in Regret. Mary Watson plays the Hyper-Competent Sidekick to Inspector Lestrade, proving herself to be very handy in languages and other areas. In this sense, she plays the trope straight, especially as Lestrade is The Hero. However, the men definitely defer to Mary "Pintsized Powerhouse" Watson as the real authority.
- In Of Gods And Men with a couple of bribes of apple pie, Light gets Ryuk to fly all over Great Britain searching for Horcruxes.
- Kit Bennett, PhD. in Children of Time: she's not much the leader type (just like her dad, she has no problems with following someone else's lead), but she's got a Time Lord's brain.
- In Mega Man Recut, Proto Man is this to Wily. It's lampshaded frequently.
- Dauntless has Edith who, while less competent than Lelouch, still holds more power than anyone on his staff and is incredibly competent at everything except battle and chess.
- Kocho acts as Naruto's secretary in The (Questionable) Burdens of Leadership of a Troll Emperor and is noted by Naruto as being "freakishly competent". It helps that she's a Technopath.
- The All Guardsmen Party end up being this, due to usually being the only sane men, relatively speaking, to their Interrogators.
- Alfred, the Rupert's batman. The Guardsmen instantly bond with him over this.
- The Diplomacy Adept has this going for him as does an old female Adept they had for a previous mission. The former takes out a traitor that no one but him noticed and the latter could hide enough sidearms on her person for the entire team and she led a cleansing operation of the remaining members of a Nurgle cult.
- In Neither a Bird nor a Plane, it's Deku!, Mercy is Lexi Luthor's sparring partner, chauffeur, accountant, secretary, and best friend.
- Older Than Steam: Puss in Boots, who happens to be a trope on his own.
- Monkey King Sun Wukong from Journey to the West is a nearly invincible god who swears loyalty to the very gullible human monk Xuanzang, and ends up kicking the asses of most of the monsters and demons Xuanzang encounters on his journey.
- In Ali Baba and the Forty Thieves, the slave girl Morgiana singlehandedly uncovers and thwarts every one of the thieves' plans to murder Ali Baba without alerting them to her involvement before he even suspects he's in danger.
- Amy from season 3 of Within the Wires. Without her, bureaucrat Michael Whitton (our narrator, nominally the protagonist) would get literally nothing done. (Not that it stops him from sending her scathing memos for not being formal enough in front of visiting bigwigs for his taste.)
- Georgie from Wooden Overcoats. She's great at... well, everything, and it's pretty clear that without her, Antigone and Rudyard (mostly Rudyard) would run Funn Funerals into the ground. When she has a 10-Minute Retirement, Antigone and Rudyard both beg her to reconsider specifically because of this — Rudyard directs the funerals and Antigone handles the corpses, but Georgie keeps everything running like a well-oiled machine, as well as handles any physical labor that needs to be done. During her stint as the Mayor's secretary, she proves to be great at that, too.
- Older Than Feudalism: The whole wise servant/dumb master dynamic is probably one of the most popular staples of ancient Roman/Greek comedy theater. See A Funny Thing Happened on the Way to the Forum for a modern take on the old Roman cliche.
- The zanni or servants of Commedia dell'Arte took up the role with the same plot: a clever servant arranges that his foolish young master and the master's foolish love can marry.
- Boracio to Don John in Much Ado About Nothing.
- RWBY: Team JNPR is led by Jaune Arc, who begins as a incompetent bumbler (he gets better later). His teammates, Pyrrha Nikos, Nora Valkyrie and Lie Ren are all shown to be extremely competent fighters.
- Yorks the goat-slug in Broken Quest is this to Big Bad Sid. A prime example in episode 3, when Yorks thinks a plan to set the heroes against centaurs and get them killed was a failure. It was a complete success as far as Sid was concerned, however, because his only real objective was to see if he could get the heroes to kill their own horses to substitute their hooves for the centaur hooves they were tasked to get.
Yorks: Wait. You set up a fake boat business. Had me run it for a week, in disguise, to lead them to a sacred centaur hunting grounds all to... (calming breath) trick them into killing useless horses they already hated.
Sid: Holy crap! It sounds even more gi-nees when you say it. Magic mirror, fat lady taking a bath.
Yorks: But we helped them across the river! They're moving faster now on foot! what was the point of any of this?!
Sid (No longer paying attention to Yorks): Oh yes, that's nice.
- Greasy, sidekick to Peeper at Whateley Academy in the Whateley Universe, though with Peeper the bar is exceptionally low.
- Mephisto claims that this was common for the Captain Patriotic / Kid Sidekick pairings that popped up all over the place during World War II, mainly because the 'superheroes' were usually the result of Super Soldier experiments performed by 'eccentric' but patriotic researchers under the control of the military. The 'kid' sidekicks were actually their handlers, and older than they appeared, as the whole purpose of setting these 'flag heroes' loose on criminals and saboteurs was to see if the test subjects could handle the stress of combat and covert ops without going berserk.note
- "Commander" Jeremy Wickstrom in Chad Vader. Although he is a little off as well.
- Phelous and The Cinema Snob gained this role in Kickassia. They're not too happy about it.
- In Max and Matt's Bro-Ops Let's Play of Guacamelee!, Max plays as Juan, Matt plays as Tostada. Matt is much more competent.
- The alternative scenes to Sage's Speed Racer review had The Other Guy shout at Critic that because Critic has kidnapping issues, he has to be the one to sort it out and provide bribes to the police.
- Outside Xbox has a much-beloved intern for their GTA Online heists called Nerascus, who has a habit of waiting for the rest of the team at the dropoff point, having fulfilled his end of the heist long before the rest of the crew. He also has incredible taste in vehicle livery.
