Annabelle Lennox is just another little girl, just starting school. She's clever and learns rather quickly. She hates bullies and will not tolerate them trying to be mean. She likes to draw and color in her free time. Her favorite subject of her drawings would be the black truck that is usually parked outside her house.

[[SecretKeeper She never tells anyone, however, that the truck isn't ''just'' a truck.]] It is her best friend, [[{{Film/Transformers}} Ironhide]].

Set after ''Film/TransformersRevengeOfTheFallen'', this series is a prime example of what happens when characters wrestle control away from the writer. [[ Black Crayons]] started out as a short one-shot about the idea of Will Lennox's daughter growing up with the knowledge of the Autobots and how this would affect the child. It was intended to be something short, but as its creator, Creator/BookwormGal, quickly learned, the tale was nowhere near finished. Currently, the series consists of sixteen stories. Most are short one-shots, but four are multi-chapter pieces including the most recent one that attempts to rewrite ''Film/TransformersDarkOfTheMoon''. The series was written out of order and most can be read separately, but taken as one long story as well.

''Black Crayons'' consists of (in order):

* [[ Black Crayons]]
* [[ Drawings]]
* [[ Babysitter's Nightmare]]
* [[ Night Sky]]
* [[ Bully]]
* [[ Parent-Teacher Conference]]
* [[ Everybody Needs a Birthday]]
* [[ Babysitting, Take Two]]
* [[ When I Grow Up]]
* [[ Party Time]]
* [[ Language Lessons]]
* [[ Summer Vacation]]
* [[ My First Decepticon]]
* [[ Nightmares]]
* [[ A Child's Innocence]]

Or they can all be read [[ here]]

In addition to the main stories of the series, a collection of drabbles was written.

* [[ 100 Black Crayons]]

While most of the stories are [[LighterAndSofter simply sweet and adorable tales]] about a little girl who just so happen to be friends with the Autobot Weapon Specialist, it manages to avoid being ''too'' sweet. Characterization of the relationships between the humans and Cybertronians is the main focus. Later stories, as Annabelle begins to grow older, become more serious in tone. Her father and best friend ''are'' in the middle of a war against the Decepticons and events begin to draw closer to home...

!!''Black Crayons'' contains examples of:

* ActionGirl: Mikaela for the humans and the Arcee triplets for the Autobots.
* AliensSpeakingEnglish: Just like in the movies, the Cybertronians have downloaded the language. Also inverted when Annabelle begins learning to speak Cybertronian.
* AlternateUniverseFic: "A Child's Innocence" is a rewrite of ''Film/TransformersDarkOfTheMoon''. One of the differences is removing [[ReplacementScrappy Carly]] and putting Mikaela back in the storyline.
* AnArmAndALeg: In "A Child's Innocence": [[spoiler: Starscream, Megatron and Optimus Prime all suffer this.]]
* AngerBornOfWorry: Chromia scolds Ironhide for nearly getting himself killed [[ShipTease out of concern for him]].
* AscendedExtra: Sarah Lennox and Annabelle Lennox
** Also, as mentioned in AlternateUniverseFic, Mikaela is not PutOnABus in the rewrite of ''Film/TransformersDarkOfTheMoon''.
* BadlyBatteredBabysitter: While never actually hurt, Jennifer ends the night with her nerves frayed due to a "possessed truck" outside.
* BattleOfWits: Between Annabelle and Simmons, who is trying to prove that a five year old girl can't possibly be trusted with a secret as massive as the Autobots. Too bad that he, like so many others, underestimated her...
* BerserkButton: For Annabelle, anything that might put her Autobot friends in trouble. For Sarah, anything that could threaten her child or husband. For Ironhide, anything that could physically, mentally, or emotionally harm Annabelle.
* {{BFG}}: Ironhide. Annabelle always makes sure to include his cannons in her drawings.
* BilingualBackfire: At one point, Ironhide begins teaching Annabelle some basics about how to speak Cybertronian. [[ChekhovsSkill This allows her to listen in and participate on a few conversations she wasn't supposed to understand.]] This includes Skid and Mudflap's plans to pull a prank on Ironhide, [[spoiler:use the universal greeting on Barricade, and hear a critical conversation about a traitor in the Autobot's midst]].
* BreakTheCutie: [[spoiler:Annabelle, in chapter 11 of "A Child's Innocence," is reduced to a heart-broken, crying child after witnessing the Xanthium explode.]]
* CallBack: In "A Child's Innocence", once again Mikaela hotwires a car.
* CarFu: In "A Child's Innocence", [[spoiler: Mikaela pulls this off fairly well against a Decepticon]].
* CheerfulChild: Annabelle
* ChekhovsSkill: Annabelle speaking Cybertronian. First, a cute way learn about the Twin's pranking plans. [[spoiler:Later, [[ChekhovsBoomerang a life saving skill]]]].
* ChronicHeroSyndrome: In "A Child's Innocence", Annabelle goes into Chicago while the Decepticons and Autobots are fighting because she feels the need to do something and that villains should be punished for what they are doing.
* CruelAndUnusualDeath: [[spoiler:Jolt being disintegrated by Sentinel's [[BuffySpeak rust gun thing]]]].
* CuteMute: Just like in the films, Bumblebee.
* DamselOutOfDistress: In "A Child's Innocence", when Mikaela is kidnapped by [[spoiler: Dylan Gould]], she actually puts in an effort to try to escape.
* DarkerAndEdgier: While most of the stories in the series have been fluffy, little tales intended to make you smile, things start becoming more serious around "My First Decepticon" and become positively dark at points in "A Child's Innocence."
* DeathByAdaptation: [[spoiler: Brains]], who survives the events of Film/TransformersDarkOfTheMoon, dies in "A Child's Innocence".
* DyingMomentOfAwesome: [[spoiler:Jolt who continuously holds onto Sentinel Prime before succumbing to the effects of Sentinel's rust gun.]]
* EyeScream: [[spoiler:Starscream courtesy of Sam Witwicky]] suffers this in "A Child's Innocence"
* FaceDoodling: [[spoiler:Annabelle]] does this to [[spoiler:the twins, Mudflap and Skids,]] in "Summer Vacation." Glitter was also used.
* FallenHero: [[spoiler:Sentinel Prime]]
* FanVerse
* GenreSavvy: Barricade is aware that trying to harm Annabelle will cause one to suffer the wrath of Ironhide as well as the other Autobots who care for her. [[spoiler: In "A Child's Innocence", it is this reason that he decides to let Annabelle go when she is taken prisoner.]]
* GoingDownWithTheShip: [[spoiler:Wheelie and Brains. The former survived.]]
* HalfTheManHeUsedToBe: A few examples in "A Child's Innocence":
** [[spoiler: Flareup is on the receiving end of this trope courtesy of Sentinel Prime.]]
** [[spoiler: Sideswipe inflicts this on a Decepticon in Chicago.]]
* HugeGuyTinyGirl: Ironhide and Annabelle. It is portrayed as [[HonoraryUncle a]] [[PapaWolf platonic]] [[BigBrotherInstinct relationship]].
* HumansAreWarriors: The human characters get their moments in [[spoiler: Chicago]] in "A Child's Innocence". Especially Sam [[spoiler: towards Starscream as mentioned in AnArmAndALeg and EyeScream]] and Mikaela [[spoiler:towards a Decepticon as mentioned in CarFu]], Wheelie doesn't call her "Warrior Goddess" for nothing.
* HumansThroughAlienEyes: Ironhide, and later Bumblebee, have initial trouble with how the crayon drawings are supposed to represent reality.
* InnocentInaccurate: [[spoiler:Annabelle thinks the skeletons in Chicago are Halloween decorations]].
* InterspeciesFriendship: Annabelle (human) and Ironhide (Cybertronian). Actually, just like in the movies, there a lot of this going on with the main characters.
* InTheBack: Similar to the scene in ''TransformersDarkOfTheMoon'', [[spoiler:Sentinel ''attempts'' to do this to Ironhide. This time, however, Ironhide is able to react in time and make the traitor face him head-on instead]].
* LighterAndSofter: Most of the earlier-set stories are more light-hearted than the movies.
* LittleMissBadass: Annabelle Lennox stands up to bullies and in "A Child's Innocence", [[spoiler: drives a piece of debris into Sentinel Prime's leg]].
* LittleStowaway: [[spoiler:Annabelle in "A Child's Innocence"]].
* KilledOffForReal: [[spoiler:Jerry Wang, Jolt, Flareup, Laserbeak, Shockwave, Brains, Dylan Gould, and Sentinel Prime]].
* {{Mama Bear}}: Sarah Lennox. Don't mess with her daughter. It's a bit of a RunningGag for characters to believe that not even the Decepticons could stand up to her.
* MeleeATrois: Optimus Prime vs. Megatron vs [[spoiler:Sentinel Prime]]
* TheMole: Just like in TransformersDarkOfTheMoon, [[spoiler:Sam is forced to serve as one against his will]].

* MythologyGag: The Universal Greeting: [[TransformersTheMovie Bah wheep grana wheep ninny bahn]]
* NoEndorHolocaust: Unlike the third film, this is averted in "A Child's Innocence". Having Cybertron coming through the space bridge is mentioned to be causing earthquakes near fault lines and that there is the distinct possibility that having the planet completely come through could rip Earth apart.
* NotAllowedToGrowUp: Averted. Annabelle begins the series at age four, but she's six by "A Child's Innocence."
* NotSoDifferent:
** Soundwave takes note of [[spoiler: Dylan and his father Richard Gould and their thirst for power]], even having to make sure that they were not Cybertonians as well as comparing the former to Megatron.
** After Optimus Prime [[spoiler: kills his former mentor Sentinel]], he notes that the latter became no different than Megatron.
* {{Papa Wolf}}: Not only does Annabelle have [[BadassNormal Will]] [[HumansAreWarriors Lennox]], but she also has [[TriggerHappy Ironhide]]. Not to mention most of the Autobots have become rather fond of her...
* OhCrap: In "A Child's Innocence", Barricade has this reaction when he assigned with guarding Annabelle because he is afraid of what [[PapaWolf Ironhide]] (not to mention the other Autobots who care about her) will do to him if he finds out.
* PluckyGirl: Annabelle. She's sweet and friendly, but she can be as brave and stubborn as her parents (or Ironhide) when she needs to. [[spoiler:She sneaks her way into a ''warzone'' because she thought she needed to be there]].
* PragmaticVillainy: [[spoiler: Barricade decides that it would be safer for him if he let Annabelle go so that he would avoid suffering the wrath of the Autobots who care about her (mainly Ironhide).]]
* TheQuisling: Just like in Film/TransformersDarkOfTheMoon, [[spoiler: Dylan Gould]].
* RedEyesTakeWarning: Averted with Wheelie, but played straight with the other Decepticons.
* SaveTheVillain: For a certain value of "villain." In "My First Decepticon", [[spoiler:when Barricade shows up, Annabelle serves as a distraction so that [[TheBully Carl]] can escape]].
* TheSociopath: Laserbeak takes great joy in killing humans.
* SecretKeeper: Not including those connected to the government or [=NEST=], those who know the truth about the Cybertronians include Sam, Mikaela, Annabelle, their families, [[AndZoidberg and Leo]] (though he hasn't appeared in the series).
* ShipperOnDeck: Annabelle is waiting rather impatiently for [[spoiler:Ironhide and Chromia]] to realize they belong together.
* ShipTease: Chromia and Ironhide have a few of these, to list a few:
** In "A Child's Innocence", Chromia's thoughts show that she would save Annabelle even if she did not care about the child because she knows that Ironhide cares about her and she hates seeing Ironhide upset.
** As mentioned in AngerBornOfWorry, Chromia scolding Ironhide for risking himself.
* ShoutOut: At one point in "A Child's Innocence," [[ActorAllusion Dutch]] says [[{{Series/Firefly}} I'm a leaf on the wind. Watch how I soar.]]
** In the same story, Mikaela compares Sam to [[Film/DieHard John McClane]].
* ShutUpHannibal: Just like in Film/TransformersDarkOfTheMoon:
** Sam finds himself facing off against [[spoiler: Dylan Gould]], a human who has agreed [[TheQuisling to assist the Decepticons in their takeover of Earth]], provided that he is unharmed after the takeover (and possibly gets a fair share of the spoils; such as being leader of the human slaves, which is made more clear in "A Child's Innocence"). Sam tries to reason with [[spoiler: Dylan]], who ignores his pleas and turns on the final Pillar for the Space Bridge, warping Cybertron into Earth's atmosphere. [[spoiler: Dylan]] then kicks Sam to the ground, telling him "You chose a side? You chose wrong!" Moments later, Sam appears with a metal bar in his hands, leading to this final conversation:
--->'''[[spoiler:Dylan]]:''' See that? (Points to Cybertron) I just saved a whole other world! You think you're a hero? You think you're a HERO!?"
--->'''Sam:''' No... [[MeaningfulEcho I'm just the messenger]]! (Rams Dylan with the metal bar, causing Dylan to collide with the Pillar's energy beam, electrocuting him to death.)
** Optimus Prime does this to both Megatron and [[spoiler: Sentinel Prime]].
---> '''Megatron:''' (as he's about to finish off [[spoiler: Sentinel Prime]]) But I'll have to finish off Optimus as well this time, he and his followers have gotten in the way once too many times. I have to wonder, though... what will it be like without him around? Who will I be without him?\\
'''[[spoiler:Sentinel Prime]]:''' I don't know. Who would he be without you?\\
'''Optimus Prime:''' Time to find out. ([[spoiler:Cuts Megatron's right arm off with his axe and later [[StopHittingYourself beats Megatron with his own arm]]]])\\
'''[[spoiler:Sentinel Prime]]:''' [[spoiler:Optimus... all I ever wanted... was the survival of our race... You must see why I had to betray you]]...\\
'''Optimus Prime:''' (picks up Megatron's gun) [[spoiler:As I said before you didn't betray me, Sentinel. You betrayed yourself.]] (takes aim at [[spoiler:Sentinel]]) \\
'''[[spoiler:Sentinel Prime]]:''' NO, OPTIMUS...!\\
'''Optimus Prime:''' (Fires the gun, killing [[spoiler:Sentinel]])
* SpannerInTheWorks: In "A Child's Innocence", Annabelle inadvertently convinces Megatron to turn on [[spoiler: Sentinel Prime]] when she says that [[spoiler: Dylan Gould and Sentinel Prime]] are responsible for Megatron's plan. Note that Annabelle really ''does'' believe that what happened in Chicago was the work of [[spoiler: Dylan and Sentinel]].
* SparedByTheAdaptation: So far in "A Child's Innocence," [[spoiler:Ironhide, Starscream, Wheeljack, Soundwave, Wheelie, and Megatron]] have survived their fates from ''Film/TransformersDarkOfTheMoon''.
* StopHittingYourself: In "A Child's Innocence", [[spoiler: Optimus beats Megatron's with the latter's severed arm in the FinalBattle in Chicago]].
