A character is said to have lived for centuries; his name found all throughout the history books. When our hero or heroes finally meet him, he reveals his deepest, darkest secret — he's not actually immortal. As it turns out, he is merely the latest in a long line of Bob The Immortals. Apparently, the original Bob secretly trained a second to take up his name, appearance, and personality. The second continued this with a third, and so on until the present day. (There was always someone to Take Up My Sword, or for Passing the Torch to.)
This can be made much easier if the first Bob The Immortal wore a mask all the time (possibly while claiming that the mask is what gives him immortality) or no one can agree on what the original looked like beyond 'he wears a Badass Longcoat and carries around a huge sword.'
This can also apply to Time Travellers, if they're sighted in multiple time periods and are thought to be immortal because of it.
Related to (and partially named for) Legacy Character. The primary difference between the two is that most Legacy Characters aren't attempting to appear immortal, but are instead Mythology Gags, promoted sidekicks, or simply revivals of older, forgotten characters. See also You Kill It, You Bought It. May overlap Shrouded in Myth.
The inversion (Bob the Immortal pretends to be a series of different people) is My Grandson Myself.
- Naruto has Madara Uchiha. The real one died long ago (though not quite as long ago as most people thought); but Obito Uchiha assumed his identity to carry on his plan, and was able to use the name to spark a new war. Madara was resurrected thanks to Kabuto's necromancy, and the two of them began openly working together. Of course, it eventually turns out neither necessary like each other: Madara was the one who manipulated Obito into being willing to carry out his will and always intended to be revived to see his plan through, even if that meant sacrificing Obito's life in the process. Which is fair, because Obito never intended to revive Madara in the first place and intended to go the plan alone and reap the reward.
- In Code Geass, In the end Lelouch ultimately passes on the Zero identity to Suzaku, who then kills him. Thus, Zero lives eternally as a crusader for justice.
- In The Phantom, the main character is the 21st Phantom: All of them come from a single family where the son of the current Phantom becomes the next Phantom when the current one is killed. The page quote is sworn by each of them upon taking up the mantle. Since only a very select few are privy to this knowledge, and because of the Phantoms' tendencies to have cast-iron Character Shields, he is believed to be immortal by the natives of his home country and most of his foes.
- During the period where the original was frozen, there were no fewer than three men who assumed the Captain America identity. The first two were specifically recruited by the U.S. government to carry on the legacy of the original, with the president fearing that American morale would dissipate if the country learned that Captain America had perished.
- The Confessor from Astro City turned into this. His sidekick picked up for him pretty seamlessly when the original was killed off. (It confuses the crooks a lot because the original actually was an immortal vampire who got dusted; his replacement, while not immortal, is also no longer bothered by garlic or crosses. This is implied to have low-level criminals around the city freaking the eff out, because they seem to think the Confessor actually came back from the dead invulnerable to traditional vampire weaknesses.)
- And Jack-In-The-Box from the same series has recruited an understudy for exactly this purpose when he realizes he's getting a bit old for the tights. This was actually the son of the original Jack (killed in action) who took up the mantle. In 2016, this Jack's son (grandson of the original) is preparing to "join the family business" himself. While there are suspicions, most of the public doesn't seem to grasp there has been more than one Jack.
- And it's heavily implied that the Gentleman isn't actually ageless, but rather he was gradually replaced by his partner the Young Gentleman as he grew up.
- In one of the ill-fated series offered by Atlas Comics in the 70's, it was left completely up in the air whether the hero was an immortal superman or the latest in a long (family) line of adventurers.
- The main antagonist of the Blake and Mortimer two-part book The Sarcophagi of the Sixth Continent claims to be none other than the ancient Indian emperor Ashoka the Great. Mortimer met him during his youth in Colonial India and meets him again in 1958. However, the latter Ashoka turns out to be the daughter of the former. We never learn who the previous Ashoka was, though...
- Although it has never been seen through for any long period of time, Batman often hints, outright states, or puts into action the idea that Batman must live even if he dies. This idea was the driving force behind the "Azbats" Dork Age.
- With Bruce Wayne's death/transportation back in time, Dick Grayson took up the Batman mantle in his place, holding onto it for a while even with Bruce's return to the cowl. While a lot of heroes were aware of the change — even guys like Booster Gold or Deadman — the villains seemed to be mostly oblivious.
- In Batman Beyond, Terry McGinnis makes good on this promise (despite some initial objections from Bruce himself).
- Superman & Batman: Generations plays with this by having the Bat-Family work to maintain the illusion that Batman has always been a single person, even when the mantle is passed from Bruce to Dick Grayson to Bruce Wayne Jr. and finally back to the original after he becomes immortal and takes up the job again in 1999.
- In Iron Man Noir, Baron Strucker reveals that Baron Zemo isn't one person, but a series of chemically brainwashed men. Zemo wears a hood in case anyone recognizes him; the current Zemo is Howard Stark. Strucker hopes to turn Tony Stark into the next Zemo, since the one they have now has "outlived his resourcefulness."
- Another Marvel Elseworld, The 5 Ronin, has a unique version of this trope. The equivalent of Wolverine is reputed as a man who cannot die — you can see him lose his head, bury him, then meet him in town a few days later. It turns out it isn't one man at all, but rather a large group of identical brothers who had gone their separate ways. They aren't even trying to spread this legend, one of them turned evil and, wearing a mask, started killing the others. By the end of the first issue, only one brother remains, and he's got quite a reputation to live up to.
- One time Spider-Man villain The Black Tarantula (now an on and off ally/foe of Daredevil) was revealed to be passed from father to son in a manner very reminiscent of The Phantom. In fact, the Tarantula cropped up shortly after the 1996 Billy Zane movie.
- Transformers: More than Meets the Eye revealed that there has been at least four different incarnations of Ultra Magnus. The original died a long time ago, but Chief Justice Tyrest liked the idea of an "eternal lawman". To accomplish this, he spread rumors that Magnus faked his death and created a suit of Powered Armor in his image. The Ultra Magnus in MTMTE is actually a small 'bot named Minmus Ambus, and the third to take the title of Duly Appointed Enforcer of the Tyrest Accord.
- At the end of V for Vendetta, V dies, and Evey never looks under his mask. Evey becomes the new V, and takes on an apprentice of her own who will become V after her.
- Subverted in the 2011 The Shade mini-series. The Shade is in Barcelona to help out his adoptive "daughter", the vampire hero La Sangre. He arrives just as her archenemy, a murderous zealot called the Inquisitor, returns. Sangre explains she first fought him during World War I and he seemed to fall into a molten pit in 1944. However, he soon returned for more clashes over the decades. Sangre had assumed that his devoted followers had vowed to take up the mantle to continue his crusade and thus was fighting imposters. However, a check on the blood from the latest fight has her realizing it is indeed the original Inquisitor all this time, kept alive by a deal with a demon and possessing the bodies of his acolytes for his later clashes with Sangre.
- In the remarkably inventive Harry Potter fic ''Where in the World is Harry Potter?'' by nonjon, Nicholas Flamel is not immortal, instead using legacy immortality and a lot of magic, including a Time Turner and metamorphmagus powers, to preserve the masquerade. The latest Nicholas Flamel is none other than Harry Potter. This reveal is foreshawdowed early in the fic with references to The Princess Bride and the Dread Pirate Roberts is explicitly mentioned as an in-universe ficitonal example of this scheme.
- The Dark Knight Trilogy:
- Ra's Al Ghul in Batman Begins, if we judge only by what is seen on screen. If you know about Ra's from other sources, Epileptic Trees suggest themselves. This isn't to be confused with how Ken Watanabe's character went by the name at the beginning of the movie, as it was all but stated Henri Ducard was the title's real holder already with him as a decoy.
- The Princess Bride: The Dread Pirate Roberts is feared for being immortal, killing and pillaging ships as he goes. We later find out from Westly, that he was the most recent Dread Pirate Roberts passed on to him from a long line of infamy.
- In Arthur Christmas, Santa Claus is actually a title passed down from father to son, starting with the original Saint Nicholas. As the film opens, Santa Claus XX is getting too old to continue his duties, but is afraid of retirement.
- In The Evil Wizard Smallbone, it turns out that Smallbone himself isn't the original, who lived hundreds of years ago. There's actually been a long line of master-apprentioces taking up the name and role.
- Inverted in The Belgariad, where the Tolnedrans think it's the case for Belgarath and Polgara, who are both genuinely The Ageless.
- Another example in the same series is Queen Salmissra, though she's somewhat of a subversion as she was never intended to deceive the public. Instead, it's the Nyissans' own absentminded god, because he forgot to make the original Salmissra immortal. He's not even very put out when someone finally sets things straight, so it's possible the entire ruse was never necessary in the first place.
- A similar inversion occurs in the Deverry novels, where Nevyn keeps popping up at the side of key historical figures over the course of his 450-year existence. Opinions are divided as to whether the name of Nevyn is passed down from father to son or master to apprentice.
- Also inverted in the Ender's Game series. Valentine is a published writer under the name "Demosthenes," and she was also born about a thousand years ago (although, through the anomalies of general relativity, she hasn't had any more years of subjective experience than any normal human). Because Demosthenes has been writing for a thousand years, he/she/they are believed to be this kind of legacy character, rather than all of the books and articles being written by the same person.
- The villainous Mycroft Ward from The Raw Shark Texts planned to combine this with Transferable Memory so that there would always be someone alive who shared all his memories and life experiences. By the time the book starts, Mental Fusion has given way to Hive Mind and Mycroft Ward is a self-perpetuating meme rather than an individual.
- Lampshaded in Homeland, where a student assumes the identity of his dead master (who had a disfigured face), and briefly considers the possibility of the pattern continuing for millennia. It doesn't happen, though.
- The titular (anti)hero of Santiago: A Myth of the Far Future. There have apparently been at least four 'Santiagos', and the book ends with a fifth.
- Dean Koontz's "Frankenstein" series shows that Victor keeps an enhanced clone of himself in a tank, being fed regular uploads from Victor's memory, ready to step up if the original is killed. A semi-subversion also exists, since Victor is actually the original Dr. Frankenstein from the famous story, with his lifespan stretched by assorted biotech.
- In the first episode of the revived Doctor Who, this is one theory about how come the same man was seen in various times (Titanic, JFK assassination, etc.) while often looking different. Harriet Jones briefly assumes the same thing on meeting the Tenth Doctor.
- In a later series of Red Dwarf, it is revealed that Ace Rimmer is not one man, but a succession of hologram Rimmers from countless dimensions who have taken on his identity to continue the legacy of the original.
- Christopher Chance in the current incarnation of Human Target is this.
Old Christopher Chance: ''Well it ain't really a name, least not one anyone was born into. I got it from the guy that taught me, he got it from the guy that taught him. 'Christopher Chance' is the guy you go to when no one else can help.
- While the first season of Wonder Woman is set in World War II, the second season (referred to from there on as "The New Adventures of Wonder Woman") moves the setting to the present day. When Steve Trevor's son meets Wonder Woman, this is one of the theories he has for her looking the same after three decades. She, of course, sets him straight.
- In the first Ravenloft Gazetteer, the narrator S speculates that this is why stories of Harkon Lukas keep cropping up throughout Kartakan history: that the original Lukas had been such a successful bard that many others since have adopted his name as a means of self-promotion.
- The Hordemaster Epic Destiny from 4th Edition of Dungeons & Dragons has this as a class feature: if a hordemaster dies, one of his followers takes up his name and is treated as being exactly the same character.
- The 5th edition Champions Universe included the hero Black Mask, whose family has been pulling a Phantom since the American Revolution. It's not clear whether the Black Mask actually claimed to be immortal, but everyone else certainly treats him/them like it.
- Diablo III has the Crusaders, an entire order of holy knights who take up the name and title of their masters when said master dies. This includes the Player Character if they play a Crusader.
- In the first Fable, it is implied by an NPC that "Jack Of Blades" (the game's main villain) is not immortal, but several people wearing his robe and mask throughout the ages. In The Lost Chapters, it is revealed that this is partially true — Jack can possess people from beyond the grave if they put on his mask.
- This is the explanation for Yoshimitsu appearing in both Tekken and Soulcalibur — the leader of the Manji clan adopts the name, personality, and fighting style, while using the same sword.
- This is justified by the fact the sword itself is named "Yoshimitsu". To the clan, referring to the sword or the one who wields it is one and the same. In doing so, they are able to portray their leader as one who can transcend death.
- Soulcalibur V lends even more credence to this, as the successor of the Yoshimitsu from SC to SCIV explicitly refers to himself as Yoshimitsu the Second.
- In The Elder Scrolls IV: Oblivion, the Gray Fox works this way. He actually was many people in a row wearing the same magical mask. The mask was cursed by the Daedra it was originally stolen from; wearing it permanently erases the wearer's identity from history, meaning nobody will ever recognize them (masked or not) as anyone other than the Gray Fox. After the curse is broken, the wearer is able to use the mask to perfectly mask his identity, but the mask can be removed and the effect will end.
- Mass Effect 2 has the Shadow Broker, an unseen entity which commands a galaxy-spanning information network. The current Broker is Liara T'Soni, who took command secretly after killing her predecessor, an unnamed never-before-seen alien who did the exact same thing years before. The origin of the network is as-of-yet unknown.
- In Zettai Hero Project, the Unlosing Ranger (a sendup of the entire sentai genre of heroes) manages to achieve this. The tendency (at least for the past few exchanges) seems to be for a dying Unlosing Ranger to hand off the Morphing Belt to the best available passerby. Nobody ever picks up on this, at least not until the events of the game, where the latest recipient is laughably weak and unheroic.
- Ajax from City of Heroes is a hybrid of this and Complete Immortality: the first Ajax was utterly invulnerable — right up until the point where a two-bit punk named Ralph Valetti shot him. His powers transferred to Ralph as he died, and a few weeks later Ralph took up Ajax's name, costume, and heroic efforts.
- Mistbeard in Final Fantasy XIV. The Hullbreaker Isle dungeon has you fighting your way to the wreck of his ship in order to get the mask back for the latest one, who plans to lock it up and end the tradition.
- Subverted in Rise of the Tomb Raider, Trinity thinks that the Prophet has this but he turns out to actually have Resurrective Immortality.
- In Pillars of Eternity, the archmage Llengrath has this. The first Llengrath, unlike his fellow archmage Concelhaut who is a bonafide Immortality Seeker, believed that it did not matter whether or not he survived as long as his knowledge did. Llengrath founded a cult dedicated to preserving his life's work. The title "Llengrath" along with all of the memories of the previous Llengrath has been passed down from master to apprentice for generations. You can kill the current Llengrath in a Bonus Boss fight. Transferring the save data to the sequel reveals that the title of Llengrath has been passed down to a successor.
- The Crone of Maltak in Dominic Deegan.
- The Immortal Captain Roberto from Open Blue. It's All There in the Manual.
- Champion of the Whateley Universe. He's been around since the 1920's or 1930's, and he's powered by 'the Champion Force'. Only the current Champion is Champion VI, and there's another one in training at Superhero School Whateley Academy. When one Champion dies, he passes the Champion Force on to his successor who then gets the powers.
- The Legend of Tarzan simultaneously plays it straight and subverts it. Some elders in the native Waziri village claim to be hundreds of years old. It turns out, by the end of the episode, that they're referring to their family names, not the people themselves. But then, after the main characters are gone, one elder casually remarks another was "only" about 170.
- A villainous version in Gargoyles is the Hunter. The original was a scarred man who Demona clawed as a young boy; the title then passed to Prince Duncan and his descendants, who dedicated themselves to hunting her and other Gargoyles down. Demona knows that they're a family, having killed a good number of Hunters herself. She does sometimes use "the Hunter" to refer to the whole line, probably because there's not much difference between them all from her perspective.
- In Recess, the school's pet hamster had been replaced by the current teacher whenever it died without the students knowing for over four decades until one day, T.J. notices it die.
- In Iron Man: Armored Adventures, Moses Magnum initially cannot believe that the Black Panther has stalked him to New York City, as he is sure he killed the Panther back in Africa. He later realizes that the Black Panther that is after him is actually the son of the one he already killed.
- Used as a plot point in Young Justice, where Jaime Reyes (Blue Beetle) states that most people erroneously assume that he is the previous (deceased) Blue Beetle in a new costume. It's implied that a similar situation exists for the new Robin, Tim Drake, who inherited the mantle after the death of the previous Robin, Jason Todd.
- On Miraculous Ladybug, Alya finds evidence that Ladybug is a student their age, but when the Pharaoh attacks, he reveals that Ladybug defeated him thousands of years ago. It was a different Ladybug, but Marinette drops hints that she really is that old to throw Alya off her trail.
- Downplayed in Defenders of the Earth, where the Phantom's supposed immortality is only mentioned in one out of the sixty-five episodes produced. What's more, the version of the Phantom featured in the series has no male heir and has chosen his daughter, Jedda, to be his successor, which would ultimately destroy the illusion of immortality.
- In an episode of The Simpsons, when Lenny says he heard Duffman died of liver failure, Duffman replies "Duffman can never die — only the actors who play him!"
