'''Basic Trope''': A character disappears from a series with no InUniverse explanation.
* '''Straight''': Bob disappears from the series ''Legends of Troperia'' halfway through, with no mention of what became of him.
* '''Exaggerated''':
** Roughly 80% of the cast is gone by the end of the series, and none of them are ever spoken of again.
** Bob was essentially the star of the show as the TitleCharacter, but disappeared without explanation in the second episode.
* '''Downplayed''': Bob disappears from the series, and is finally mentioned offhand several years later.
* '''Justified''':
** Bob was just a BitCharacter to begin with.
** Alternatively, Bob was a OneShotCharacter.
** The writers somehow forgot Bob existed to begin with.
* '''Inverted''': Bob shows up halfway through ''Legends of Troperia'' [[RememberTheNewGuy with no explanation of why he's there or where he came from, and is treated as if he had been there the whole time]].
* '''Subverted''':
** Bob disappears early on, but then he shows back up later.
** Bob disappears early on, but his disappearance is then used for a CerebusRetcon
** [[UnreliableNarrator Alice, the P.O.V.-character]], has ([[ImpliedTrope undiagnosed]]) [[ScatterbrainedSenior Alzheimer]]. Bob hasn't become non-existent, he simply no longer registers to her.
* '''Double Subverted''': Except it's not him, it's another character named Bob.
* '''Parodied''':
** By the end of the series, it's down to exactly one character, but they still steadfastly refuse to address anyone's departure.
** Bob literally disappears into thin air in the middle of a scene and no one comments on it.
* '''Zig Zagged''': Bob's disappearance is treated this way, but Alice is PutOnABus, then minor character Dave gets ADeathInTheLimelight but when Carol's actress quits, her character is simply never mentioned again.
* '''Averted''':
** "Our lead actor just quit. We won't mention him again" "The viewers won't buy that! We'll establish that he had a big argument with Charlie offscreen as the reason why he no longer hangs out with the group."
** Any departures have an InUniverse [[PresentAbsence explanation]].
** No one is written off, period.
* '''Enforced''':
** The actor playing Bob suddenly quit, died, or was [[RoleEndingMisdemeanor fired under very unsavory circumstances]] (arrested for a drug or sex crime, has been accused of saying or doing something racist, sexist, or homophobic, asked for more money and exchanged cross words with the management) and the writers didn't have time to fully explain what happened to him or [[TheOtherDarrin replace him with another actor]].
** Bob wasn't a major character or important to the plot, so they just forgot about him.
** ExecutiveMeddling forced Bob to be written out for whatever reason (audience complaints over [[CreatorsPet not being likeable]] and/or MoralGuardians claiming he's a bad influence)
** "Dammit, our lead actor just quit! What do we do about the character of Bob?" "Just don't mention it."
** [[NoCelebritiesWereHarmed Bob Fezman]] [[note]]and other ('''[[TakeThat un]]''')flattering Fez wearing [[NonIronicClown come]][[StageMagician gicians]][[/note]] became a big no-no [[DistancedFromCurrentEvents after T. Cooper passed away]].
* '''Lampshaded''': "Where'd Bob go? Remember...he used to travel with us? Why the blank stare?"
* '''Invoked''': Not applicable. (This trope is beyond the control of the characters.)
* '''Exploited''': Emperor Evulz takes advantage of Bob’s disappearance to [[TheBadGuyWins successfully take over his hometown.]]
* '''Defied''': Not applicable. (This trope is beyond the control of the characters.)
* '''Discussed''': "Man, I have heard that Bob has disappeared." "Yeah, and ''why'' did he disappear?" "Good question!"
* '''Conversed''': "Where did Bob go, and why aren't they talking about him?"
* '''Deconstructed''': Because of Bob's disappearance, the fans of the show keep asking the cast and crew what happened to him.
* '''Plotted A Good Waste''': Bob's departure - and the apathetic response to such - is later used as a plot point when a character [[WhatTheHellHero calls out the hero]].
* '''Implied''': Bob does not appear at all in twenty episodes in a row.
