History AllThereInTheManual / WesternAnimation

* The book six of the series HeyArnold:[[http://www.amazon.com/Arnold-Arnolds-Files-Groening-Bartlett/dp/0439381495/ref=pd_sim_b_3 Arnold's E-Files]] confirms that Brainy is in love with Helga and that he has HiddenDepths.

* ''WesternAnimation/AvengersEarthsMightiestHeroes'' has tie-in comics containing stories and bios that confirm such details as the Crimson Dynamo's real name, [[ComicBook/IronMan Ivan Vanko]], and the identity of the "giant robot" ComicBook/IronMan fought in his first episode, Ultimo. They also record the capturing of some criminals whose defeats did not receive inclusion in the show's 52 episodes.

* The tie-in comic book for ''TheAvengersUnitedTheyStand'' attempted to make sense of some of the baffling elements of the cartoon, such as providing a decent explanation as to why the Avengers were wearing gaudy, {{Animesque}} battle armor. It also provided an origin for Ultron.

** The Fiendship Is Magic comics, unlike most of the other comics that are based on spin off stories, are crucial to learning about the origins and backgrounds of several villains including Sombra and Lord Tirek.

** The later issues handle [[LeftHanging dangling plot threads]] from the show, such as what exactly happened to Grey Gargoyle, Queen Karnilla, and Princess Ravonna. It also set the stage for {{Quicksilver}} and the ScarletWitch, [[WhatCouldHaveBeen who would've appeared in the show had it been picked up for a third season]].

* In the {{Creator/Nelvana}} AnimatedAdaptation of TimothyGoesToSchool which is based on the works of RosemaryWells. Yoko's mother would sometimes bring up the other family members who still live in Japan along with mentioning her daughters early memories of living in Japan as a toddler. While we do see a glimpse of Yoko's grandfather in the episode "The Takatombo". We never actually see the other family members of Yoko in the show or even see the rest of Japan in general. In 2001, Wells made a book called "Yoko's Paper Cranes" where you can actually see Yoko as a very young kitten still living with her grandma and grandpa along with seeing cranes. We also see Yoko and her grandmother Obaasan feeding cranes,having tea, and Ojisaan showing her how to make paper cranes. This is also the only time Yoko's grandmather is actually seen.

** In Lindsay's case while it was never said explicitly there are hints tracing back to the first episode that implied she was rich.

** While it's said in the show it's heavily implied that Lindsay was rich.

* A lot of information about ''InvaderZim'' comes from interviews and commentary given by the creators, [[ScrewedByTheNetwork partially because the show ended before a lot of stuff could be used]] and partially because a lot of the interesting stuff probably never would have been used anyway. Also, it turns out [[AllThereInTheScript every minor character has a name]].

* ''TheFairlyOddparents'' had a special "77 Secrets of the Fairly Oddparents" revealed Timmy's middle name (Tiberius) and Wanda's full name (Wanda Venus Fairywinkle). Also, a [=TurboNick=] special revealed Cosmo and Wanda's family tree.

** King Sombra's aftereffects on the CrystalEmpire are indeed NightmareFuel-worthy, but we never know anything of his direct rule--until ComicBook/MyLittlePonyFriendsForever shows flashbacks of him [[spoiler:enslaving a Crystal Bard for its CompellingVoice and siccing his guards on its trail when it finally escapes.]]

** The later comics revealed some info about the TimeSkip between the original show and its [[ReTool ReTooling]] into ''The New Batman Adventures''. Notably, they explained what happened between ComicBook/{{Catwoman}} and Batman that lead to her cutting all ties to the Bat-Family, something [[WeUsedToBeFriends that was only ever vaguely hinted at on the show]].

*** Quite a few background details for this series are also found primarily online; for example, the web serial "Republic City Hustle".

* The ''Franchise/ScoobyDoo'' gang's ages are never stated within the series, but they are within outside material. An official calendar from the original series pinned Velma at 14, Shaggy and Freddy at 17, and Daphne at 16. A more recent example - bios from a video game - based off the same series has Velma at 15. Sources also have their sizes as: Fred is 5′11″ and 185 pounds, Shaggy is 6 feet tall and 160 pounds, Velma is 4′9Prime; and 95 pounds, and Dapnhe is 5′7″ and 115 pounds.

* In ''WesternAnimation/AdventureTime'' it is never fully stated what happened to Finn's (human) parents. However, in the Adventure Time Encyclopaedia book it is revealed that Finn's parents abandoned him in a basket in the woods for unknown reasons. He was left there until he was found by Jake's parents (the aftermath of the abandonment is seen in the flashback scenes of Memories of Boom Boom Mountain)

* Much information about the ''WesternAnimation/TeenTitans'' could be learned from the ''ComicBook/TeenTitansGo'' comic book such as Terra's origins and much of Starfire's family.
* The ''ScoobyDoo'' gang's ages are never stated within the series but they are within outside material. An official calender from the original series pinned Velma at fourteen, Shaggy and Freddy at seventeen, and Daphne at sixteen. A more recent example - bios from a video game - based off the same series has Velma at fifteen. Sources also have their sizes as: Fred is 185 pounds and 5'11, Shaggy is 6 feet tall and 160 pounds, Velma is 4'9 and 95 pounds, and Dapnhe is 5'7 and 115 pounds.

* On ''TheFlintstones'', when the Rubbles first find baby Bamm-Bamm in a tortoise-shell basket on their doorstep, they quickly learn that he has near-superhuman strength. No explanation was ever given for this strength on the show. Some 30 years after the series aired, a trading card finally gave an answer. [[spoiler: Bamm-Bamm was raised by dinosaurs in the wild.]]

* ''SpongeBobSquarePants'': Do you want to know what anti-sea-rhinoceros undergarments look like? Just play the game based on "The Camping Episode".
* There's a lot of info/backstory in ''WesternAnimation/{{Motorcity}}'' that wasn't revealed in the show, but revealed by the creator, crew and the series bible, such as Julie and Claire being ChildhoodFriends, Mike's CoolBigSis Capri and Julie's mother [[spoiler:having died when she was little]]. Since some of the info in the bible (particularly regarding how Dutch and Texas interact with each other) contradicts what we saw in the series, some of this info might not be canon.

* A lot of information in ''{{Rollbots}}'' on the various tribes and special information regarding characters can only be found on the Rollbots webpage on the {{Ytv}} website, which can now no longer be accessed. Even when it was available, many aspects of it could not be viewed from outside Canada.

** Issue #21 of the Gold Key comic (story "Charmed Strife") posits that the gang have the following zodiac signs: Scooby,Aries; Fred, Pisces; Shaggy, Leo; Velma, Virgo; Daphne, Gemini.

* Each episode of ''WesternAnimation/StarWarsTheCloneWars'' is accompanied by a comic, episode guide, and creator commentary on the official site. While these normally just contain trivial info, they were all but necessary to watch the "Dooku captured" episodes. The comics explained Anakin's voluntary capture and showed how Anakin and Obi-wan got drugged, the episode guide explained how Dooku lost his sabers (the monkey-lizard pickpocketed him!) and the commentary video was Filoni explaining that he believed even Dooku can be captured by pirates if he's sufficiently outnumbered.

* In ''WesternAnimation/AdventureTime'' it is never fully stated what happened to Finn's (human) parents. However, in the Adventure Time Encyclopaedia book it is revealed that Finn's parents abandoned him in a basket in the woods for unknown reasons til he was found by Jake's parents (the aftermath of the abandonment is seen in the flashback scenes of Memories of Boom Boom Mountain)

* ''WesternAnimation/YoungJustice'' had a tie-in comic, like most [=DC=] {{animated adaptation}}s, but theirs was co-written by writers and producers from the series and went into details like why the Justice League abandoned their headquarters at Mt. Justice, how Artemis found the battle with A.M.A.Z.O., and just ''why'' {{Superboy}} hates monkeys so much. It also provided an origin for Clayface, and at least one issue contained a scene that was scripted but ultimately cut from an actual episode of the show.
