''Manga/KarakuridoujiUltimo'' has quite a large cast of characters. So large, multiple pages were made to hold them all. Especially since quite a few of these characters are verging on {{Troperiffic}}.

This page has tropes relating to all the doji in general. For tropes relating to the humans, and individual doji, look at the following pages:

!!General Tropes For The Karakuridouji
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tumblr_lbw60pKSQe1qa36cxo1_500_7005.jpg]]

The Karakuridouji - "Mechanical Boys" - are robots created by Dr. Dustan. They're "robots designed to learn", meaning that they must choose a master to guide them into finding out what is truly good or evil (This will probably lead to a few FaceHeelTurn & HeelFaceTurn in the future). Besides from what they've learned, the robots have no human emotions.

These are tropes that every (or most) Karakuridoji has. Tropes that only ''some'' (as in, three or less) of the doji have should be moved to them only.
----
* AbsurdlySharpBlade[=/=]{{BFS}}: The doji's gauntlets can transform into this.
* AchillesHeel: The only way a doji can die is if you crush their spirit sphere, which is located inside of their chests.
* AlwaysMale: Subverted, as the doji ''are'' just robots. Karakuridoji does means "Mechanical Boy" however.
** [[spoiler: After [[UnsettlinggenderReveal chapter 23]], people thought, rightfully so, that [[DudeLooksLikeALady Service]] was a boy (as much as a robot can be a boy). Then comes the last [[http://holymanga.com/ultimo-chap-51/ chapter]], and the [[WhereAreTheyNowEpilogue last we see of Service]] (as far as I can tell) is as a ''girl'' alongside Sophia and Jealousy, in school uniforms, all of the doji having [[BecomeARealBoy turned human]] courtesy of [[BigBad Dr. Dustan]].]]
* AnimeHair: If doji had any power over gravity, they use it on their hair.
* BarbieDollAnatomy: Ultimo and Vice have this in the prologue, as they're robots. Let's just hope this carried over to the main manga...
* BecomeARealBoy: [[spoiler:In the final chapter,[[BigBad Dr.Dustan]] [[ResetButton turns back time]] and transforms all the doji, good and evil, into humans to live out their lives alongside their former masters.]]
* BigScrewedUpFamily: See RoboFamily below.
* CallingYourAttacks: Both in normal and mecha form.
* CastOfSnowflakes: As shown in the picture above, they are clearly distinguishable even in silhouette.
* ColorCodedCharacters: The doji all have a theme color (e.g. Ultimo's is scarlet, Vice's is green and iron, Jealousy's is blue and pink).
* CreepyDoll: Subverted by the doji, as they're robots. But yes, they are ''very'' creepy.
* DoAnythingRobot: They have a lot of powers at their disposal.
* DudeLooksLikeALady: '''Most of the doji.'''
* EmbodimentOfVirtue: The strongest under Ultimo are the Six Perfects of Buddhism. They oppose those based on the Sins.
* GoodEyesEvilEyes: A lot of the evil Douji tend to have narrow-looking eyes that lack shines.
** The Good doji, such as Sophia, have wide, child-like eyes in contrast to some of the evil doji's narrowed eyes.
** Jealousy has black marks under his eyes, giving him a [[MrFanservice shadowy look]].
* HumongousMecha: The doji in Icon form.
* MrFanservice: Most of them.
* NoBiologicalSex: Given that Karakuridoji are actually advance robots from the future/past/it's complicated.
** [[spoiler: Then in [[http://holymanga.com/ultimo-chap-51/ the last chapter]] this get's {{subverted}} as they all [[BecomaARealBoy turn human]]. Except for, [[http://2.bp.blogspot.com/-oOfHwpk27iY/WR-BQlczojI/AAAAAAAA33s/upG47GGB_TgjR1OvvktldmJyVMRTo2aRACHM/s16000/0051-061.png apparently]], Service (who is now a girl) they are all male.]]
* NonHumanSidekick: To their masters.
* PullingThemselvesTogether: The doji can do this pretty quickly, as long as they have a master.
* ReallySevenHundredYearsOld: Milieu has said that Dunstan dropped them all off around the same time... 900 years ago. Ultimo's weary appearance when Yamato encounters him in the antique shop suggest that the doji have been waiting for their masters to reincarnate since then.
* RidiculouslyHumanRobot: Just ''look'' at them. Why Dunstan would give them hair, clothes, the ability to eat and sleep, and to basically be ''children'' is very wanted information.
** As a new chapter reveals, the doji can even take ''baths.''
* RoboFamily: Some of the doji have refered to Dunstan as their father. Jealous has also called Ultimo his brother.
** Which causes some amount of {{Squick}} when you remember Chapter 12. Avaro molesting/raping Service would be considered BrotherSisterIncest.
* RobotKid: A hundred of them.
* SevenDeadlySins: There is a set of mechanical boys based on the Sins. They are the strongest under Vice.
* ShapeshifterWeapon: The Karakuridoji are capable of transforming their gauntlets into various oversize weapons. They can even transform their entire bodies.
* SlidingScaleOfRobotIntelligence: Subverted. While some of them do exhibit emotions and knowledge of human nature, [[{{TheStoic}} the]] [[{{LackOfEmpathy}} others...]]
* {{Stripperific}}: Their outfits tend to expose a lot of skin, especially the chest and the back.
* SuperRobot: All of the Douji are extremely powerful robots.
* TechnicolorEyes: Although it's hard to tell on some of the doji, if you look close enough, you can see that their pupils are a rather bizarre color. (Ultimo-Green Eyes and Red Pupils, Jealousy-Pink Eyes and Blue Pupils, etc.)
* TinMan: Subverted with the doji, as they have no human emotions (except for a few that embody the characteristics of their particular virtue/sin).
* WhatMeasureIsANonHuman: A complicated topic in this manga.
