* ''Manga/MobPsycho100'': Arataka Reigen is a famous esper who has the young Shigeo Kageyama (aka Mob) as his disciple, who has great esper powers. In reality, Arataka is a ConMan who has no powers and [[MoochingMaster only uses Mob to manage real spirits]]. Subverted since Arataka is a father figure for Shigeo, teaching him to use his powers correctly and encourage him to not use his powers against other people.

* Interesting case in the biopic ''Film/SearchingForBobbyFischer'' - trainer Bruce Pandolfini (who was the main advisor of the film!) comes over as a {{Jerkass}} who is ultimately responsible for prodigy Josh Waitzkin resigning chess, by hammering on the fight part of chess. He has a point, but his pupil is more into fun and the clash of the personalities lets everything go south.

* Tondemon Higashi from ''Battle Club'' like Genma below is a played with example. He led Swan Academy to eight successive all-Japan championships but is shown to be SecretlySelfish and shown to be something of a JadedWashou. Kuniko Mukoda StartOfDarkness was a wrestling prodigy like his first student Ginkakuji Tamami. However he saw her as little more then a PoorMansSubstitute and never believed that she could make it. He quickly planned on replacing her upon meeting Tamami’s daughter.

->"I've already mastered everything you have to teach me. But I decided to disregard all I learned from you. All your moves look retarded in addition to being completely useless in a fight. See ya loser!"

Compare ObsoleteMentor, who can do what they teach and are capable of teaching, but they are a bit behind in how it works. Compare MorePoweredProtege, in which the disciple has more powers than the mentor (and sometimes overlaps with this). Compare {{Sabotutor}} for those who deliberately train their pupil wrong. For characters generally giving advice for things they know nothing about, see TheBlindLeadingTheBlind. See also AntiRoleModel, when a character is presented as someone the audience should not emulate.

* ''Film/KungPow'': Master Tang to Wimp Lo. "We taught him wrong on purpose. As a joke."

* ''Literature/HarryPotterAndTheChamberOfSecrets'': A famous magician, Gilderoy Lockhart, is hired by Hogwarts school to teach the students Defense Against Dark Arts. However, when he gets to teach, it quickly becomes apparent that he's rather incompetent, while passing it off as "accidents". That he's revealed to have stolen anonymous magicians' feats in order to become famous doesn't help. This was actually {{invoked|Trope}} by Dumbledore. when questioned by staff about why he was hiring so incompetent a teacher, he said there were many things Lockhart could teach the students; how ''not'' to act, for instance.

* ''VideoGame/WingCommander4'': Reckless veteran Maniac teaches rookie Catscratch some flight maneuvers. catscratch almost gets shot down trying them out in his next mission, and you have to choose whether to complete your own mission or rescue the rookie.

!!Examples

* In ''Manga/CellsAtWork'', Red Blood Cell ([=AE3803=]) is given a Kohai Red Blood Cell to look after and mentor. Only [=AE3803=] is the resident CuteClumsyGirl with NoSenseOfDirection and gets [[AttentionDeficitOohShiny easily distracted]], while her kohai is disciplined and serious about the job. [=AE3803=] herself lampshades she's a terrible senpai and even apologises to her kohai. Though to her credit, what she lacks in competence, [=AE3803=] makes up in [[{{Determinator}} determination]], continuing to deliver oxygen even during the DarkestHour and vowing to keep going to the very end. It is this undying determination that does inspire her kohai.

** Happosai, the grandmaster of Anything Goes Martial Arts. While a very formidable martial artist, he's a terrible teacher who makes Genma look proficient in comparison. All of the flashbacks of him with Soun and Genma show him [[MoochingMaster forcing his students to steal food and underwear for him]], rather than teaching them any proper martial arts. When he returns in the present and takes Ranma in as his student, he also adds in groping Ranma-chan's breasts and making her wear girly outfits. It's little surprise all his students try to get rid of him and at times attempt to murder him whenever given the chance.

* One episode of ''Series/{{iCarly}}'' has Carly turn to Spencer for art lessons after being unable to even draw a decent looking rabbit. Despite being a talented artist, his mentoring included tactics such as waking her up in the middle of the night to draw his foot (which was covered in a sticky green substance), making her draw hobos in the park, and a lecture on the history of the color yellow. Carly gets fed up and leaves for a different art teacher, however she turns out to not be much better as she only got so far as teaching the class to make straight and unconnected lines before Spencer calls her out on being uncreative.

** In "Guide To Shyness", Cookie decides to teach a bunch of shy students how to have "Cookie Confidence". He makes them to a lot of insane things he himself did, like slam-dunk a basket ball using a gigantic overpowered trampoline, use a mop-bucket slingshot, and dig tunnels through the school. Eventually, his student get fed up and turn against him when he tries to make the fight a psychopath, ironically displaying the very confidence he'd worked to teach them in telling him off.

* ''VideoGame/PunchOut'': Glass Joe is known for being the worst boxer in the franchise. That being said, he's the one who trained Gabby Jay from ''Super Punch Out'' how to box. Gabby Jay's only win is against his own mentor, and his record ends up being about the same.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Applejack and Rainbow Dash serve as this in the episode "Non-Compete Clause". While normally good teachers, their competitive nature makes them unable to teach the students the lessons on cooperation as they end up constantly arguing with one another instead. In the end though, it works out with the students assuming they showing them what cooperation isn't in order to give them the idea of what it is. Twilight was able to figure out the truth, and it shows that in the end, the two don't get any better.

* ''Literature/HarryPotterAndTheChamberOfSecrets'': A famous magician, Gilderoy Lockhart, is hired by Hogwarts school to teach the students Defense Against Dark Arts. However, when he gets to teach, it quickly becomes apparent that he's rather incompetent, while passing it off as "accidents". That he's revealed to have stolen all of anonymous magicians' feats in order to become famous doesn't help.

** Ranma's father Genma is a played with example. Most of the time he is actually a very competent teacher of martial arts who does know how to instruct and motivate (although he is a jerk, morally speaking); albeit in a sink or swim, spartan way, style. However, there is the case of the "Cat Fist" technique which was a fiasco that left Ranma mentally traumatised for life and where he didn't bother reading the full manual on how to teach that technique which warned that it was dangerous and stupid.
** Happosai, the grandmaster of Anything Goes Martial Arts. While a very formidable martial artist, he's a terrible teacher who makes Genma look proficient in comparison. All of the flashbacks of him with Soun and Genma show him [[BadBoss forcing his students to steal food and underwear for him]], rather than teaching them any proper martial arts. When he returns in the present and takes Ranma in as his student, he also adds in groping Ranma-chan's breasts and making her wear girly outfits. It's little surprise all his students try to get rid of him and at times attempt to murder him whenever given the chance.

In some cases, their student will be well aware of how bad they are and simply attend their lessons out of pity. Others will be honest and tell them how bad they are. Then there are those students who will think they are being great teachers by showing them what not to do.
