A series of three fanfics set in an alternate version of the TigerAndBunny universe where Barnaby's parents didn't die when he was four. Unfortunately, ''he'' ends up dying at age 13, a fact by which his parents cannot abide so they build him a robot body to live in.

!!Tropes found in this fic:

* AbusiveParents: Rotwang to [[spoiler: Tora]], for a given value of "parent." Might have been a better "parent" to Cis.
* AccidentalKiss: Subverted [[spoiler: Kotetsu and Barnaby]] meant to give each other a kiss, just not on the mouth.
* AccidentalMisnaming: When Kotetsu tried to soothe Barnaby (who was destroying various pieces of technology in his panic to get back to his body) by calling him Bunny, Barnaby's response was make the words "not a bunny" appear on a screen.
* AdultFear: The whole series was set in motion by Emily and Barnaby Sr. not wanting to bury their (only) son.
* AlternateUniverse: Barnaby's parents are alive and well, having apparently never discovered Maverick's criminal connections.
* AIIsACrapshoot: Dr. Rotwang just wanted to create a better robot than the Brooks'. He didn't count on it becoming sentient.
* ArtificialIntelligence: Of course and it applies to [[spoiler:Tora]]
* AttendingYourOwnFuneral: Lampshaded and averted; Barnaby doesn't go with his parents to the funeral of his original human body specifically because it would be awkward and creepy.
* BigBadDuumvirate: Maverick and Rotwang
* BigBrotherMentor: Barnaby seems to think of his relationship with [[spoiler: Tora]] as this, as he's teaching the younger entity about the world. [[spoiler: As Tora's perception of different types of relationships alters with his growing knowledge, however, it starts to blur a bit. Barnaby admits at the end of the arc that he's not exactly sure where they stand anymore.]]
* BodySnatcher: [[spoiler:Happens to Barnaby twice, with his consciousness split from his physical body]]
* BrainUploading
* ConvenientColorChange: [[spoiler: Tora]]'s digital ghost alters based on emotions. Once Barnaby figures this out, he's a lot easier to teach.
** RedEyesTakeWarning: The quickest way to tell when either one of the androids are well and truly pissed, or not under their own control.
* CorruptCorporateExecutive: Maverick
* CrashIntoHello: How Kotetsu enters into Barnaby's life.
* DeceptivelyHumanRobots: Barnaby and [[spoiler: Tora]]
* DigitizedHacker: Barnaby, though he uses his powers for good.
* [[spoiler: DrivenToSuicide: Rotwang's official cause of death]]
* EnemyMine: "Enemy" might be overstating things, but [[spoiler: Tora]] does not like Kotetsu and only works with with him to keep Barnaby safe.
* [[spoiler: ExplosiveOverclocking: Maverick's cause of death and the destruction of the H-01 army.]]
* [[FandomNod Fanon Nod]]: [[spoiler: Tora's human form is based on Dark Kotetsu.]]
* FlawedPrototype: What Maverick views [[spoiler:Tora]] as after he builds [[spoiler:an army of H-01's]]. Rotwang also views the older-model Barnaby as infinitely inferior to Cis.
* HeroicSelfDeprecation: Kotetsu did this until Barnaby [[CrowningMomentOfHeartwarming told him to knock it off.]]
* HoistByHisOwnPetard: [[spoiler: Maverick offlines Barnaby and steals his body without knowing about a crucial overheating problem, and is later killed in the explosion when it overclocks and has a core meltdown.]]
* IncurableCoughOfDeath: Opens the first fic.
* MadScientist: The Doctors Brooks aren't evil, but everyone seems to acknowledge they're just a little bit 'off'. Nathan even refers to them as "our benevolent mad scientists" once, and Barnaby thinks his parents would take the moniker as a ''compliment''. Rotwang is a more straight example.
* MamaBear: Emily Brooks. Not only was the BrainUploading her idea, but if both she and Barnaby Sr. are angry about something she will always be the angrier of the two.
* MoreExpendableThanYou: One of the conflicts in the second part of the arc is how much it freaks Kotetsu out that Barnaby seems to take this view. Barnaby reasons that it's fine because he can be rebuilt, but agrees to be more careful. Then we find out in part three that if certain bits were destroyed, he ''wouldn't'' be able to be reconstructed...
* MundaneLuxury: Barnaby was damn near giddy the first time he got to people watch since having his soul transferred into his robot body.
* NoSocialSkills: Barnaby tries, but after years of isolation, too much attention tends to make him a nervous wreck. [[spoiler: Tora has little feeling for humans in general]], but eventually warms up to the Brooks, and Kotetsu to a ''much'' lesser degree.
* OnlyKnownByTheirNickname: Subverted. If Kotetsu or [[spoiler: Tora]] are talking ''about'' Barnaby they will refer to him by that name. As far as [[spoiler:Tora's]] concerned Barnaby's name is Angel.
* PeoplePuppets: Barnaby pulls this trick twice on a mechanical level; [[spoiler: once to kill the first H-01]] and once on the Wild Tiger armor, both times to save Kotetsu. [[spoiler: Gets done to him as well when his second body is stolen.]]
* ThePlan: [[spoiler: What Maverick's plan in part three is revealed to be once Agnes starts looking at it "from a showman's point of view."]]
* PromptFic: Would you believe that each of the fics in the trilogy started as a prompt?
* PurelyAestheticGlasses: robot Barnaby wears them.
* RevengeBeforeReason: [[spoiler: Rotwang snaps and sends Tora out to target the Brooks after "losing" one too many times to them. Everyone assumes this has also become Maverick's motivation in part three, until Agnes explains to Kotetsu exactly how much he'd benefit if his plan works.]]
* RidiculouslyHumanRobots: [[JustifiedTrope Justified]] by Barnaby, who used to be human. [[spoiler: Tora]] was an accident.
* SecretIdentity: Whenever Barnaby goes out in public he uses the name Rory Brooks.
* ShoutOut: Several, as the author admits borrowing from known robot tropes.
** Barnaby's net-diving is similar to that used in GhostInTheShell.
** [[spoiler: Tora's forming sentience]] is a shout out to TheVision.
** [[spoiler: Maverick using Barnaby's body to seemingly create a robot revolution]] is pulled from Film/{{Metropolis}}.
* SmartPeopleBuildRobots: The good Doctors Brooks and Brooks are roboticists.
* SoulJar: What Barnaby's robot body amounts to.
* UnPerson: Barnaby is one, essentially
** [[spoiler:However he and Tora eventually gain a sort of personhood status]]
* VagueAge: Barnaby stopped keeping track of his age when he was 16. No one else's ages have been stated.
* WeAreAsMayflies: Barnaby and [[spoiler:Tora]]
* WhatMeasureIsANonHuman: A driving point in the series. Part of the reason Barnaby stayed hidden for so long was because even as a fully sentient android, he was still legally "just a robot" and could be ordered detained or even dismantled. There's also a sliding scale among the characters as to how much Barnaby and [[spoiler: Tora]] still qualify.
