!'''Alastair Sterling'''
[[quoteright:216:https://static.tvtropes.org/pmwiki/pub/images/ohs_al_556.png]]
''Al is the inventor who started it all.''

%%* Badass Mustache: No, those aren't upper lip wrinkles. That's a damn ''stache''.
%%* TheBear
* CarpetOfVirility: Always conspicuously very hairy. Brendan's favorite part is the beard.[[note]] Though while Al is usually mustachioed, he doesn't always have the full beard.[[/note]]
* {{Gayngst}}: [[spoiler: There's no mistaking that Al loves Brendan and loves being around, frolicking with and being intimate with Brendan. But while Brendan is confident with himself and who he is, Al is a lot more concerned with what other people will think. Brendan wants to be Al's ClosetKey, but Al has never consented to it.]]
* HotMenAtWork: Especially to Brendan.
* {{Hunk}}
* LimitedWardrobe: Usually seen wearing the same trademark black shirt, which also happens to [[FormFittingWardrobe tightly hug his muscles]]. Notably, the shirt is usually one of the few seen objects that is never monochromatically red or blue, but rather a conspicuous brownish black. Then, when Al is resurrected, he is given only ''one'' set of clothes, including that shirt.
* MrFanservice: And he initially doesn't even realize it, but Brendan sure does. True enough, the comic constantly sprinkles fanservicy shots of Al's muscles and body hair, plus the occasional ShirtlessScene.
* NotSoStoic: He can get real angry at Brendan if he feels like Brendan's acting up. [[spoiler:Then there's robot!Al having a crisis about his status as an android...]]
* ParentalIssues: Briefly mentioned, but [[NoodleIncident he doesn't want to talk about it]].

!!Original Al
''[[PosthumousCharacter December 12, 1961 –- April 15, 2005]]''

''While he was alive, Al hid behind a tough and imposing exterior –- and after death he became a near-mythical figure among humans and robots alike.''

* ArmoredClosetGay: Al didn't want people to know then...
* CoolOldGuy: He wasn't ''that'' old, but he still thought of men Brendan's age as "kids".
* DeathByOriginStory
* DistractedByTheSexy: [[spoiler: To the point where [[http://ohumanstar.com/chapter-2-page-34/ Brendan was too much for Al to handle]].]]
* IntelligenceEqualsIsolation
* TheLostLenore: After Al's death (and before his resurrection), [[http://bluedelliquanti.blogspot.com/2011/11/new-short-comic-oh-maker.html he was totally this to Brendan]].
* MirrorMonologue: [[http://ohumanstar.com/chapter-2-page-52/ This]].
* MoralityPet: As weird as this sounds, he's this to Brendan. Brendan's not evil, but the majority of his sympathy revolves around his relationship with Al and Sulla.
* PosthumousCharacter
* SilverFox: Al thought he was [[OldMaid too old]] for men Brendan's age and that Brendan shouldn't be attracted to him. Brendan responds by invoking this trope.
* ToplessnessFromTheBack: His shirt already [[FormFittingWardrobe hides nothing]]. But then [[http://ohumanstar.com/chapter-2-page-47/ his shirt]] ([[http://ohumanstar.com/chapter-2-page-48/ and the rest of his clothes]]) finally came off for some memorable back shots ([[SceneryCensor but no naughty parts]]).
* TransparentCloset: To the [[{{Gaydar}} very observant]] [[http://ohumanstar.com/chapter-2-page-43/ Brendan]].
* YoungerThanTheyLook: Al was prematurely grey and looked quite a bit older than he actually was. He was only 39 when he and Brendan first met, and 43 when he died.

!!Resurrected Al

''Now that he has been mysteriously resurrected in a robot body, Al searches for answers from the only person who knew him as he really was.''

* ArmoredClosetGay: ...and he's content that Brendan never told anyone.
* BackFromTheDead
* BrainUploading: Which raises lots of questions -- if Brendan Pinksy, the world's leading expert on BrainUploading (next to Al himself, of course) could only copy an inadequate template of Al when Al was dying (this template, of course, became Sulla), then who made this absolutely spot-on copy of Al -- and when? [[spoiler:well...]]
* CloneAngst: He's not really happy being a robot made from the code of his original self.
* CoolOldGuy: Sulla adores him.
* FamedInStory: Now that he's BackFromTheDead, no one is expecting him to be alive. In the public consciousness, Al is a ''late'' legend of robotics technology.
* FishOutOfTemporalWater: [[spoiler: Having pioneered most of the technology that is ubiquitous by 2021, Al thinks he can handle seeing what the world has become. Brendan thinks he isn't. Brendan was right.]]
* HeroicBSOD: [[spoiler:Gets one big crisis when he realizes he no longer a human. It didn't help that Brendan's robots had to restrain him right after he pushed Brendan away.]]
* RidiculouslyHumanRobot: It'd take a close-up look to tell that he's not human, which is a clue that whoever had his body made had some serious resources.
* RobotMe
* SoulJar

!'''Brendan Pinsky'''
[[quoteright:216:https://static.tvtropes.org/pmwiki/pub/images/ohs_brendan_5049.png]]

* ClosetKey: [[spoiler: {{Averted|Trope}}. Brendan ''wants'' to be this for Al, but Al never feels ready for everyone to know. It's still a secret by the time Al dies, and remains so when he's resurrected as a synthetic. Brendan hasn't told ''anyone''.]]
* FieryRedhead
* HotMenAtWork: Especially to Al. [[http://ohumanstar.com/chapter-2-page-34/ Case in point.]]
* PermaShave: [[http://bluedelliquanti.tumblr.com/post/48459662103/has-brendan-tried-growing-a-beard-because-two-beards This]] is [[FourthWallMailSlot why]] Brendan never grows a beard.
* StraightGay

!!Past Brendan
''In his business partnership with Al, Brendan was seen as the ideas man –- the charismatic and ambitious spokesman who got people to care about their creations.''

* {{Genki G|irl}}uy: Irrepressibly enthusiastic.
* LikesOlderMen: He really likes Al's mature older looks.
* {{Manic Pixie Dream G|irl}}uy
* ThePerfectionist: Brendan did not know ''how'' to fail. But soon after Brendan was hired, Al pointed out that Brendan's lack of failure meant he hadn't learnt the meaningful lesson that some failures are inevitable, as well as how to deal with them.
* PrettyBoy
* {{Red Oni|BlueOni}}: To Al's Blue Oni.
* TheTwink: {{Subverted|Trope}}. Brendan certainly had the youthful age and body type. But when it came to men, he turned out not to have any of the stereotypical ''innocence'' of twinks. [[spoiler:As it turned out, Brendan was far more experiened and confident than Al.]]
* WideEyedIdealist: Complete with the [[http://ohumanstar.com/chapter-2-page-25/ wide eyes]].

!!Present Brendan
''Since Al’s death, Brendan has matured into a shrewd inventor and a caring father who nonetheless shoulders a lot of regrets.''

* [[RedOniBlueOni Blue Oni]]: To Sulla's Red Oni.
* BrokenAce: Has this written all over him. Between the past and the present day, Brendan faced failure [[ThePerfectionist learn to face and accept failure]] one way or the other.
* FamedInStory: As a living legend of robotics technology.
* [[GoodParents Good Father]]: A good father to Sulla, as "O Maker" amply demonstrates. Particularly, he loves her as her own person, and [[ReplacementGoldfish not just an extension of Al.]] He also effectively homeschools her.
* [[HerHeartWillGoOn His Heart Will Go On]]: Oh, [[http://bluedelliquanti.blogspot.com/2011/11/new-short-comic-oh-maker.html he tries]].
* JadeColoredGlasses: Al's death really did a number on him mentally. He's far more bitter and grumpy when he meets robot!Al.
* OpenMindedParent: Is very supportive of his trans daughter, not only modifying her into a feminine body, but using her preferred pronouns and name constantly, and taking down photographs of her pre-transition.

!'''Sulla Pinsky'''
[[quoteright:216:https://static.tvtropes.org/pmwiki/pub/images/ohs_sulla_9670.png]]

''Sulla was the first robot created to perfectly resemble a human being –- Alastair Sterling -- but she is still trying to figure out who she really is. A brilliant and sensitive mind in a teenage girl’s body, Sulla knows a lot is expected of her and tries her best to impress her creator, her hero, and her newfound friends.''

* CameBackWrong: She was originally meant to be a copy of Alastair Sterling, but she was an incomplete copy, and had none of Al's memories. Through time, she started to grow up like a human child, and even requested a sex change. In the end, the fact that she CameBackWrong isn't a negative trait, as her DivergentCharacterEvolution made her a very unique character of her own. [[spoiler:Turns out the original Al is more like her than anyone knew.]]
* CloneAngst: Quite evident in ''[[http://bluedelliquanti.blogspot.com/2011/11/new-short-comic-oh-maker.html Oh, Maker]]''. [[spoiler:It's revealed in Chapter 7, that she made the copy of Al because she thought her existence was a failure.]]
* FieryRedhead: PlayedWith. While she is very much like this at home with Brendan (though not in any angry way), she is actually more of a ShrinkingViolet in public and doesn't really have friends.
* GenkiGirl: In stark contrast to Al's [[TheStoic stoic]] nature.
* LevitatingLotusPosition: [[http://ohumanstar.com/chapter-2-title-page/ This]].
%%* MotorMouth
* MoralityPet: To Brendan, even though he's not evil. The fact that Brendan accepts her the way she is shows his good side better than anything else can.
* OppositeSexClone: Yes and no. She's a synthetic copy of Al in a similar way that robot!Al is a synthetic copy of Al, but she herself chose to become a girl.
* PowerFloats: Sulla can fly and levitate. But out and about in public where she can usually pass for human, she keeps her feet on the ground so as not to appear so conspicuously synthetic. [[spoiler:When she flies to save Al's life in danger in public, she feels really ashamed and flies off.]]
* {{Red Oni|BlueOni}}: To Brendan's Blue Oni.
* ReplacementGoldfish: Originally intended to replace Al, but the result wasn't quite Al and couldn't replace him. Rather than replacing his lover, Brendan gained a daughter.
* TheReveal: [[spoiler:She was the one responsible for the resurrection of Al.]]
* RidiculouslyHumanRobot: She's one of the world's most advanced synthetic beings, and knows it. She's not worried at all about passing for human -- what she worries about is passing for female.
* RobotGirl
* ShrinkingViolet: In public.
* SomeoneToRememberHimBy: Constantly reminds Brendan of Al.
* StealthPun: She's an android who received a sex change when she was younger and whose capabilities exceed those of a human. She's both trans''wo''man and a trans''hu''man.
* SuperStrength: Has been seen swinging around tables and couches with ease -- and in flight.
* UncannyFamilyResemblance: The first thing Al notices about Sulla, and the reason Brendan wanted to prepare Al before seeing her for the first time. Needless to say, Al is especially shocked that Sulla is a duplicate of him ''[[OppositeSexClone as a girl]]''.
* WalkingSpoiler: Of the FirstEpisodeTwist kind.
