Mentor Occupational Hazard

"Elan: Will I ever see you again?

Julio Scoundrél: Well, as an older mentor figure, the most likely scenario is that I'd return only to be randomly killed by an enemy of yours so that you can cradle my dying body while swearing revenge -- so don't take it personally if I say I sincerely hope we never cross paths again."

- Order of the Stick

Being the Mentors is never an easy job. Fighting the Big Bad yourself and stopping The End of the World As We Know It would be easy -- in fact, you've probably been there, done that. But, no, now you have to take this Naive Newcomer under your wing and teach them the ropes of herodom.

If you don't have to convince The Chosen One who just wants to be normal to grow a spine and accept the Call to Adventure, you have to convince your blindly excited and dangerously eager young pupil that You Are Not Ready to learn the Dangerous Forbidden Technique. When you try to protect The Hero from the Awful Truth, you end up facing their Rage Against the Mentor. You have to maintain an ongoing conspiracy to keep The Hero Locked Out of the Loop. If they're an orphan, you have to find them a set of Muggle Foster Parents while keeping social services in the dark. You have to endure accusations of insanity when you're trying to teach your charge that Your Eyes Can Deceive You, give them advice on how to tell a love interest "It's Not You, It's My Enemies," and keep a close eye on them 24/7.

And what is your reward for all this patience and effort?

You die.

Yes, there is a 90-100% chance that the Cool Old Guy who has stood by The Hero's side through thick and thin since the first episode/chapter/installment gets offed before the climax of the story. He might get an Obi-Wan Moment if he's lucky. He's just that cool: Too Cool to Live. It's necessary for The Hero's development -- can they rise to the occasion and save the day without their teacher holding their hand? Are they ready to accept the torch?

If the student is lucky, their Mentor will stick around as The Obi-Wan or a Spirit Advisor. Either way, expect them to retreat into a Heroic BSOD for awhile, possibly mumbling "It's All My Fault," before the Unstoppable Rage kicks in and the villain responsible pays. They needn't dwell on it too long, though; it was probably all part of the plan.

This is one of the hardest deaths for an audience to accept but ironically, one of the types most likely to stick even if coming Back From the Dead has been done before. An alternate plot involves the Missing Mentor, whose removal from the story (albeit alive and well -- we can assume) still prompts The Hero to take on his greater responsibility.

Compare/contrast Dead Sidekick. Maybe the result of Opposed Mentors

Since this is a Death Trope, expect plenty of spoilers.

Anime

 * Daitokouji-sensei of Yu-Gi-Oh GX stuck around as a Spirit Advisor. He actually proved to be more trustworthy after his death, since he was a Double Agent while he was still alive.
 * One of the best-known examples, Roy Focker in Super Dimension Fortress Macross --Hikaru's "sempai" and leader of the elite Skull Squadron aboard the titular ship.
 * And in one of the sequels, Macross , Focker's death is directly referenced when the current Skull Squadron leader,, all but telegraphs his death all throughout the episode, going as far as the "pineapple salad" (in this case,  ) that spelled doomed for his predecessor, as well as similar shots and camera angles.   (almost verging on Breaking the Fourth Wall.)
 * This trope is quite frequent in Humongous Mecha Anime. Thus:
 * Mazinger Z: Dr. Kabuto. He got murdered by his rival's henchmen shortly after completing the titular robot and handing it over to his grandson.
 * Great Mazinger: In the sequel to Mazinger Z, Kenzo Kabuto to save his adoptive son.
 * Kotetsu Jeeg: It happened twice Professor Shiba got murdered in the first episode. However he got the foresight to make a backup of his personality in a computer in order to help and guide his son Hiroshi.
 * Combattler V: Professor Nanbara. He built the Humongous Mecha was the last hope for the humankind, recruited four young teens and his granddaughter, taught them to pilot it, selected his sucessor... and shortly after he died.
 * With the danger of spoiling just by mentioning the name of the series: Hikaru no Go.
 * Rurouni Kenshin has the The Ace mentor Hiko Seijuro, master of the sword school Hiten Mitsurugi, who was first abandoned by his student Kenshin Himura. About over a decade after, Kenshin returns to him to learn the ultimate technique of the sword school they both use, which could only be learned by killing the master. Subverted when Kenshin does learn the technique but did not kill his master thanks to his reverse blade sword.
 * Naruto. So. Damn.. Much. The idea of people working for the best of the next generation is a major theme, so it suffices to say that teachers have a tendency to die protecting their students or their village. To wit:, , , . Even the ones that survive tends to almost die quite a lot.
 * Subverted with for   was revived and  for.
 * Tengen Toppa Gurren Lagann:
 * G Gundam has two.
 * In The Law of Ueki, when a god candidate helps their student champion in battle, they are automatically sent to Hell.
 * This happens in The Daughter of Twenty Faces, although this is more of a Missing Mentor case, as Chiko spends the rest of the series trying to find Twenty Faces.
 * Subverted hard in Overman King Gainer.
 * Trickster Mentor Cross Marian in D Gray Man disappeared from the Black Order headquarters while he was under house arrest. Given the amount of blood and the fact that his gun and mask were found on the floor and there were signs of a struggle, he's currently presumed dead, but they Never Found the Body...
 * Most of Ala Rubra in Mahou Sensei Negima is in some way incapacitated or made incapable of helping Ala Alba out, but this trope in particular hits  hard. Gets an Obi-Wan Moment trying to take out The Dragon and everything. Of course, like everything else about him, it's awesome.
 * Ends up averted by the fact he can.
 * In Beast King Golion, this was averted with.
 * Played straight with.
 * Played straight in Death Note, where
 * There's also
 * Puella Magi Madoka Magica has
 * Fairy Tail Has who sacrificed her life to stop  Roaring Rampage of Revenge.
 * Martian Successor Nadesico has
 * Koumyou Sanzo from Saiyuki possibly intentionally allows himself to become a victim of this. He sacrificed himself to save Genjyo Sanzo (then Kouryuu) from yokai bandits intent on stealing the sutras... but as  he should have been  . This implies he knew exactly what he was doing when he allowed himself to be killed. This is supported by the fact that in his formative years he hung out with a yokai who   and the fact that he'd only appointed Koryuu his successor a few minutes before the attack, suggesting that he had detailed knowledge of what would happen and when.
 * After Szilard's death in Baccano, Maiza takes Firo aside and asks the boy to kill him, since he's already centuries old and the one reason he was sticking around for so long (revenge on Szliard) no longer exists.

Comic Books

 * Agent 355 in Y: The Last Man is both recruited into the Culper Ring and trained by the previous Agent 355. One of the techniques she passes on is that the jaw is the most powerful muscle, so when the ex-mentor goes insane and tries to assassinate the President of the United States her successor bites her neck open.
 * Averted in X Men by Professor Xavier, who died once but got better (it was never him). And like any mentor, he set a precedent that his students followed time and time again.
 * However because he's too smart and helpful, most plots especially adaptations will take him out of the story through coma or kidnapping or something until the problem is resolved. He's just not killed by them.
 * Subverted by Emma Frost, who outlives most of her students.
 * Stick, Daredevil's teacher, who dies protecting him, Elektra and his other pupils (The Chaste) from The Hand. Averted with Master Izo, who outlived all of his pupils. Although, Daredevil: Ninja seems to indicate that Stick got better...
 * Doctor Strange's mentor, the Ancient One, dies and becomes one with all reality. A subversion, since 1) he deliberately trained Strange as his successor, 2) he asked Strange to kill him, and 3) he's not "gone" in any strong sense.

Fanfic

 * Persephone in Divine Blood is killed by her daughter Hecate's ghost while aiding her granddaughter, Eija, in a purification/crossing over. Eija is not amused.

Film

 * The Obi-Wan of Star Wars
 * Obi-Wan's own mentor Qui-Gon Jinn suffered a similar fate.
 * Obi-Wan was meant to live in the early versions of the Star Wars script, but George Lucas was frustrated in that during the big battle against the death star, he would have had nothing to do. It was Alec Guinness who took Lucas aside and set him straight.
 * Yoda dies too, although of old age.
 * Mick, Rocky's mentor, dies apparently from stress about Rocky's poor decision making skills in Rocky III.
 * Merrick from the Buffy the Vampire Slayer movie.
 * Averted with Giles, who makes it through the series alive.
 * Oh, don't worry, the Season 8 comics took care of that little problem!
 * Subverted with Splinter in the Teenage Mutant Ninja Turtles movie, although we're led to believe he died at first.
 * Magi Lune in Fern Gully seems to exist entirely for this purpose. She appears in a handful of scenes only to later die at the end of the film to pass on her powers to Krysta.
 * Subverted in Reservoir Dogs: . And only then is he shot dead by the police.
 * Played straight in Kung Fu Panda with, and then subverted with.
 * from X Men the Last Stand.
 * Ramirez falls victim to this in the first Highlander movie.
 * Mufasa from The Lion King.
 * The Obi-Wan figure in the Sci Fi Channel B-movie The Lost Future neither dies nor turns out to be secretly evil, which is quite a feat, especially since he's played by Sean Bean. In the finale he even dives in front of the hero and takes an arrow to the chest that was meant for him, but contrary to expectation he manages to survive it.
 * In Iron Eagle, mentor figure and Retired Badass Chappy Sinclair goes down early on in the assault on the enemy nation that captured The Hero's father, forcing Doug to fight the rest of the battle alone. Subverted in the end when it turns out Chappy bailed out and was rescued.
 * Averted in The Matrix: Morpheus survives all three movies.
 * Dalton's mentor Wade Garrett in Road House is killed off-screen by the Big Bad's men. Dalton finds him with a knife in his chest, despite Wade supposedly being better at everything than Dalton.
 * In The Sting, Hooker's mentor Luther combines this trope with Retirony.

Literature

 * Jesus Christ from The Bible is possibly the ultimate example of this trope.
 * In a manner of speaking, John the Baptist also qualifies, as Jesus' "older" cousin and the guy who baptized him. He also qualifies in that he explicitly states he's not here to overshadow The Hero.
 * Mathin in Robin McKinley's The Blue Sword, one of the elite King's Riders, is assigned to tutor Harry Crewe in the ways of riding and combat.
 * in Garth Nix's Sabriel.
 * in Harry Potter and The Half Blood Prince. (Search your feelings; you know it to be true!). And that's just the biggest name - many, many people have commented on how nobody who ever gives Harry good advice lives to see the end of the series. (That "good advice" requirement spares big-brother-esque Hagrid.)
 * This trope also applies to
 * The penultimate example would have to be . Before you rush to disagree, recall that he gave excellent advice.
 * He also gave a very accurate explanation on the process of occlumency, although Harry was not inclined to take it to heart.
 * Indeed, McGonagall and Arthur and Molly Weasley are Harry's only parental figures that don't fall victim to this trope, and even Arthur comes pretty close in book 5.
 * in particular clearly had to die, because he was
 * Depending on your point of view, this is either played straight or subverted with Gandalf in JRR Tolkien's The Lord of the Rings. The wise old wizard, who acts as a mentor to Frodo and later to the whole Fellowship through the first part of the novel, dies in Book II of six. He does come back Back From the Dead again in The Two Towers, but Frodo has already gone his own way by then and can no longer be mentored by Gandalf; while Gandalf himself, with his increased power, becomes a leader rather than a mentor after his return.
 * Applies to Beleg in Tolkien's The Children of Hurin as well, though he's more of a big brother figure. He is unintentionally killed by his fosterling Turin.
 * That guy, what's-his-name, Obi-Wan Iroh  Julio Scoundrel ... Brom! That's it! Brom in Eragon.
 * The Bishop of Digne in the book Les Misérables.
 * Moiraine from The Wheel of Time when she fell through a doorway to another dimension that exploded.
 * Fraa  had the misfortune of being revered by the hero and being smarter than the rest of the cast of Anathem combined. So, of course he gets exiled from the not-so-hidden elf village. After a good quarter of the book spent searching for him, they reunite briefly, then he gets promptly roasted by a volcano.
 * Tad Williams' Memory Sorrowand Thorn plays this deadly straight and justifies it. The Storm King and Utuk'ku deliberately set out to kill the members of the League of the Scroll and anyone else with sufficient knowledge to potentially unravel their Evil Plan before it was complete. Naturally, all of these characters act as Mentors to various protagonists.
 * Tad Williams' Otherland both uses and subverts the trope. Played straight: Renie's mentor Susan van Bleeck is beaten to death by the Grail Brotherhood's thugs; the old hacker Singh, who helps the heroes break through Otherland's security, is killed by the operating system. Subverted: Mysterious Informant Sellars continually attempts to aid the team after losing contact with them, but manages to stay alive until the climax, after which he surrenders his physical body for a virtual one.
 * from Warrior Cats. Of course, like Dumbledore, she returned after her death to offer more guidance, and has continued to do so for the last three series.
 * Not to mention . Mentor figures in the series in general can probably be expected to die (then again, given the series in question...), but it still usually manages to be quite the Tear Jerker every time.
 * In James Swallow's Warhammer 40000 novel Deus Encarmine,  succumbs to the Black Rage, which means certain death. Rafen, grieving over his fate, is ordered to take command of   squad, and , in the Death Guard, dies, barely able to warn Rafen with his last breath of   treachery -- and not entirely coherently. Rafen speaks to his corpse in his grief, begging for guidance, and   communicator falls to his hand, letting him get out a warning.
 * Methuselah in Redwall.
 * in the Dale Brown books, who goes down crashing the EB-52 Megafortress into a Chinese ICBM site.
 * in Mistborn, although his death is deliberate. 's, in the sequel, is not.
 * In Codex Alera
 * Honor Harrington's, is killed in The Honor of the Queen.
 * And another mentor,, nearly gets killed in War of Honor,
 * In Robert E Howard's "The Tower of the Elephant", Taurus, the Old Master thief, likes Conan the Barbarian's spirit when he finds him also trying to rob the tower and takes him along, with some instruction and help. Naturally, a trap kills him.
 * Averted or Subverted with D'ol Falla, who is The Atoner on top of being the mentor. It's The Messiah who ends up falling into the Bottomless Lake.
 * Syrio Forel, Arya's "dancing teacher" in A Song of Ice and Fire. In order to buy her time to run away, he stops to fight five guards and a knight with a training sword. He successfully kills or disables the guards, but has no chance against the fully armored knight.
 * Both played straight and averted in The Hunger Games, with, but   managing to survive all three books, and even

Live Action TV
" I am not yet ready to give up. I feel alive Teal'c, like a young man... of eighty. We still have false gods to slay"
 * Notably averted on Stargate SG-1, where The Obi-Wan figure Master Bra'tac is noted for having survived through all 10 seasons of the show, despite multiple attacks by The Plot Reaper and even a feeling of depression in one early episode. He's just that badass.

"Max: Dammit, I thought that was it! I wasted that great speech."
 * Missing Mentor version in Buffy the Vampire Slayer. Wise librarian and all-round Badass Bookworm Giles takes himself out of the series to give his protege Buffy more freedom. He returns eventually and survives to the end, alive and well...though in the season 6 finale it was touch and go for a while.
 * Giles is the weekly series version of this trope -- he can't very well die at the end of an episode so Buffy can fight the bad guy alone, then come back next week. So they did the next best thing: knock him out repeatedly.
 * They did kill him off at the end of Season 8 (the B.t.V.S. Comic continuation), however. Even then, though, it was more the emphasise that Anyone Can Die.
 * Zordon from Power Rangers: Kidnapped almost immediately after quitting the Mentor job, and his first act after rescue was to give one last mentor-y bit of advice and beg for an I Cannot Self-Terminate Heroic Sacrifice. A unique case of the mentor's death actually solving all the heros' problems.
 * All of their problems until the next season, that is.
 * from Babylon 5.
 * Notably, he knew it was coming, and was trying to delay it.
 * Relic Hunter Sydney's old teacher who first gave her an interest in relics was murdered to obtain one. Twenty years later. Sydney caught up with the killer.
 * Zanki from Kamen Rider Hibiki; generally considered to be one of the better things about the show post-Retool.
 * Narumi Soukichi from Kamen Rider Double - doesn't really count as a spoiler since it occurs in the first episode.
 * Subverted in The Cape. Max is shot by Big Bad Chess, gives a tearful dying speech as he lies in Vince's arms... and then realizes it's Only a Flesh Wound.


 * Professor Maximillian Arturo takes the bullet for Quinn close to the end of Season 3 of Sliders. His body is left to be burned along with this Earth, which is being scoured by pulsars.

Manhwa

 * Interesting version in the Veritas Manhwa. The main character's mentor, Lightning Tiger, is killed right at the beginning of the story (and his pupil receives his skeletal arm in a box as a very creepy Tragic Keepsake). However, LT wasn't old, and he'd only been training the kid for about 2 months. A character attempts to justify it later by saying the he didn't die because he was a mentor; he took on an apprentice because he knew he was going to die.

Mythology

 * Merlin of Arthurian Legend.

Video Games

 * Kingdom Hearts fans, say hello (and goodbye) to Master Eraqus.
 * The player character's mentor Gorion dies in the first chapter in Baldur's Gate in a battle against the Big Bad. As he's also your foster father, this is also a case of Doomed Hometown.
 * In Metal Gear Solid, mentor figure Master Miller turns out.
 * In Phoenix Wright Ace Attorney, Mia Fey is killed right after the (very short) first case. She returns as a Spirit Advisor and The Obi-Wan for the rest of the Phoenix games and each game explains her unique state to the player.
 * In Final Fantasy X,.
 * Done in record time in Red Faction: Guerrilla - you arrive on Mars and meet up with your brother, who takes you on your first 'mission', recruits you into Red Faction and is shot by the EDF, all in the opening 10 minutes.
 * Done with the Professor in Cave Story, to the point that if you see him drop several stories and don't try to help him, he stays alive.
 * This happens to Montblanc's master from Final Fantasy XII.
 * In The Godfather: The Game, Luca Brasi takes you as Aldo Trapani under his wing for the early missions, before he "sleeps with the fishes."
 * In Etrian Odyssey II: Heroes of Lagaard, players meet  early on and learn several important things about the Labyrinth from them. Once the player learns of their tragic history, alarm bells should be going off...
 * Duncan in Dragon Age dies in the field of battle due to the signal made by the player character and Alistair for reinforcements not being answered by Loghain.
 * But it's also subverted for Mage Wardens, for whom Badass Grandma Wynne fills the role.
 * Similarly to Duncan, Nihlus Kryik of Mass Effect 1 intended to accompany Shepard on a number of missions, most likely to train him/her as a Spectre, but he is killed at the end of the first mission by the primary antagonist, Saren.
 * Completely averted by Captain Anderson who is forced to stop being your mentor for other reasons and actually survives both the first and second game.
 * However, Anderson is the intro-level squadmate in Mass Effect 3. Things aren't looking well for ol' Dave's future, especially when one also considers the high mortality rate of intro-level companions in other Bioware games. In fact,.
 * In The The Legend of Zelda Ocarina of Time, the Great Deku Tree is cursed from the beginning of the game and dies after he sends Link off on his journey.
 * Also, Link's uncle dies at the beginning of A Link to the Past, after giving Link his sword.
 * In Ratchet and Clank: A Crack In Time, Azimuth was created specifically for the purpose of giving Ratchet a mentor figure. And, naturally, he died
 * Paladin Magnus in Ground Control, performing a You Shall Not Pass in an Order mission where you have to hold off against an endless wave of enemies. Somehow, self-destructing an Order APC creates a huge crater and destroys the supposed endless waves of enemies.
 * Guild Wars did this in every single campaign.
 * Prophecies had Prince Rurik, who took on young Ascalonian heroes as members of his personal cadre of warriors and led them on many adventures. He was killed leading his people to safety and was later raised from the dead by the Big Bad.
 * Factions had Master Shiro, head of the Monastery where young Canthan heroes trained and their leader in the war against Shiro. He was killed by Shiro in the penultimate mission.
 * Bonus points: Several of the Afflicted bosses are actually mutated teachers and quest-givers from your past.
 * Nightfall had Kormir, leader of the Sunspears and the war against Abaddon. She sacrificed herself absorbing the god's power, and now exists as a god herself.
 * Eye of the North had Gadd, vitriolic genius and Vekk's mentor/father. Killed while trying to prepare a more powerful golem to assist you in combat.
 * Giro from Mega Man ZX. Since he gets his hands on Biometal Model Z, it's easily predictable he has to bite it so that you can get to use that model yourself.
 * Zero in Mega Man X. He's watched over X from the beginning of the game, forcing Vile to retreat after X couldn't touch him. Obviously, he's the badass of the story, but he's not the title character, so he performs his Heroic Sacrifice, leaving X to face Sigma alone, with no chance at a last second rescue. Incidentally, the placement of the Vile fight in the remake justifies the over the top dialogue X uses when he faces Sigma, as it happened at the end of the previous stage, and not at the start of the fortress, making X's fury still fresh. And even though Zero gets better, he's been surpassed by X by the time he returns, and they work as a team from X3 to X8.

Web Comics

 * In Order of the Stick, Julio Scoundrel hangs a lampshade on this trope in this comic though it hasn't happened (so far, anyway). So far his plan to never meet his student again is working.
 * In Sluggy Freelance, Oasis's sensei Feng gets a bridge dropped on him within seconds of reuniting with her.
 * In Homestuck,
 * More like a mentor death contract, considering how sburb/sgrub works.
 * Happens to Lt.Col. Thomas Knowlton in The Dreamer.

Western Animation

 * Gyatso of Avatar: The Last Airbender died because The Call Knows Where You Live. Iroh's fans also lived in fear of this trope after his first voice actor died.
 * in Ben 10 Alien Force.
 * Done via flashback in Re Boot. To flesh out Bob's backstory we see his cadet days interacting with full guardian Dixon, who gets killed by Killabyte. Since she was shown using Glitch in the flashback, this was easy to see coming.
