History Characters / ForAllMankind

[[folder:Neil Armstrong]]
->'''Played by:''' Creator/JeffBranson
* AcePilot: Armstrong's piloting skills are attested when he manages to successfully take off in ''Eagle'', especially at a canted angle that required him to slowly navigate into a Lunar ascent with only a limited supply of fuel they could use.
* ComingInHot: Armstrong and Aldrin's landing is a lot harsher than it was in real life.
* PutOnABus: Since he is not the First Man on the Moon in this timeline, he fades into the background with the rest of the historical astronauts.

[[folder:Edwin "Buzz" Aldrin]]
->'''Played by:''' Creator/ChrisAgos
* InterserviceRivalry: He is Air Force, and he ribs Ed and Gordo for being "navy squids" while they rib him for being an "Air Force puke."

[[folder:Michael Collins]]
->'''Played by:''' Creator/RyanKennedy
* DeathByAdaptation: Subverted. Despite having ''2 million liters'' of fuel exploding from underneath him, Collins and his fellow Apollo 23 astronauts survive when the escape tower launches and carries the command module away, though they're all injured when the capsule lands on the beach instead of the ocean.
* IChooseToStay: When Apollo 11 appears to crash, Collins makes it clear that he refuses to return to Earth alone. Fortunately, Armstrong and Aldrin reestablish communications shortly afterwards.

[[folder:Sally Ride]]
->'''Played by:''' Creator/EllenWroe
* TheConscience: Sally Ride is the only member of the ''Pathfinder'' crew with a non-military background[[note]]she was a civilian physicist[[/note]] and is not shy about voicing her discomfort with the unexpected militarization of their mission. Even though Ed calls her bluff on shooting him, she reminds him that he, not [=NASA=], has the final call in whatever choice he makes up there and that a piece of equipment is a lot less important than the lives that would be lost in a war.
* DeadpanSnarker: Unlike Piscotti, she isn't scared of Ed to be sarcastic to him.
* HistoricalDomainCharacter: Based on the real-life Astronaut Sally Ride.
* HistoricalDowngrade: Sally Ride was the first American woman in space, something that in the show had already been accomplished a decade earlier by Molly Cobb[[note]]and, as revealed after her death, also the first LGBTQ astronaut, while in this timeline, it was Ellen[[/note]]. Then it's then [[SubvertedTrope subverted]] in the season 2 finale into:
* HistoricalHeroUpgrade: When her actions ultimately persuade Ed not to shoot down ''Buran'' and instead destroy Sea Dragon 17, preventing World War III from breaking out on Earth in the process meaning that even though she didn't become the first American woman in space as she did in real life, her actions ultimately saved millions of lives, which is something real-life Sally Ride never did.
* ScrewTheRulesImDoingWhatsRight: When it looks like Ed is going to fire ''Pathfinder's'' missiles on ''Buran'', Sally pulls her gun on him.
* WhatHappenedToTheMouse: Historically, Sally Ride was a part of the Rogers Commission that investigated the ''Challenger'' disaster and retired from NASA in 1987. It is unclear whether she took part in this universe's Rogers Commission investigation into the Jamestown attack or if she is retired as of season 3.
* YouWouldntShootMe: Although she pulls her sidearm on Ed to stop him from firing on ''Buran'', he doesn't believe that she would ever actually shoot him and pulls his own gun. Piscotty interrupts by reminding them that they're on a pressurized spacecraft so ''nobody'' should be shooting ''anyone''.

[[folder:Kelly Baldwin]]
->'''Played by:''' Creator/CynthyWu
Ed and Karen's adopted Vietnamese daughter, whom they adopted as part of the (real-life) Operation Babylift.
* DaddysGirl: Idolises Ed to the point where she applied for Annapolis because she wanted to make him proud.
* DatingWhatDaddyHates: Is in a relationship with Alexei, a Soviet cosmonaut, during the Mars mission. In "New Eden," Kelly asks Alexei not to reveal their relationship to Ed, or else he would throw him out of an airlock and MakeItLookLikeAnAccident. Sadly, it was not to last, as Alexei dies of a subdural hematoma two episodes later.
* HappilyAdopted: She's adopted by Ed and Karen, and beyond some natural curiosity about her birth family, she considers them her parents.
* SomeoneToRememberHimBy: After Alexei dies offscreen in "The Sands of Ares," it is revealed later in the same episode that Kelly is pregnant with his child.
* TheXenophile: Her greatest desire is to discover and study extraterrestrial life.

[[folder:Danny Stevens]]
->'''Played by:''' Creator/MasonThames (season one), Creator/CaseyWJohnson (season two onwards)
The eldest son of Gordo and Tracy. He appears in a recurring role in season 1 as Shane Baldwin's best friend. He becomes a major supporting character in season 2 when he returns to Houston on break from the Naval Academy and gets a summer job working at the Outpost.
* BeardOfSorrow: Grows one in Season 4 [[spoiler: due to both the strain of extended isolation in the North Korean pod and the crushing guilt for what his actions caused.]]
* DiesWideOpen: [[spoiler: When Ed and Danielle find his corpse, his eyes remain wide open, eerily staring off over the Martian horizon.]]
* DrivenToSuicide: [[spoiler:While the rest of the Happy Valley astronauts return to Earth a year later, Danny is not among them. It's later revealed that he killed himself during his exile in the North Korean capsule by allowing the oxygen in his suit to run out.]]
* DudeNotFunny: He walks in while Nick is reenacting a scene from "Love in the Skies", pulls him aside, and lays into him by pressuring him to reenact Gordo and Tracy's death scene until Ed stops him.
* ItsAllMyFault: Reveals to Ed in "The Sands of Ares" that he blames himself for Shane's death, explaining that he was the one who instigated all the trouble they got up to as children and let Shane take all the blame, which eventually led to his getting hit by a car. Danny was so deeply troubled by this that he admits to Ed that all his accomplishments (joining the Navy, becoming an astronaut, etc) were his way of honouring Shane; to live the life Ed's son would have had he lived.
** Then there's the soul-crushing guilt on his face later in the episode after he realises that his substance abuse had led to the deaths of three people, including one of his teammates.
* RecoveredAddict: Had a drinking problem sometime after Season Two that he managed to kick by Season Three. Unfortunately, Danny relapses prior to the Mars mission, and later switches from booze to pills, with deadly consequences.
* TheResenter: Is deeply resentful of Ed for a number of reasons, up to and including trying to replace Gordo as a father figure and his marriage to Karen. Ed is none the wiser to this, however.
* SanitySlippage: His time on Mars does not do wonders for his mental state and he becomes increasingly unhinged, eventually turning to drugs which only worsen this.
* StalkerWithACrush: In Season 3, he still has feelings for Karen, which manifest when he starts parking outside her house and watching the video messages she sends to Ed.
* UnwittingInstigatorOfDoom: Was tasked with monitoring the drill bit while the Soviet-Helios team were drilling for water. Unfortunately for the team, Danny was hopped up on pills at the time, and as a result the drill bit exploded and caused a landslide, killing two astronauts (as well as a third who later succumbed to his injuries) and almost killing Ed.

[[folder:Nick Corrado]]
->'''Played by:''' Creator/DanielDavidStewart
A NASA astronaut at Jamestown in season 2 and a Helionaut in season 3.
* AscendedFanboy: He tells Tracy that he was in high school when the Apollo 24/25 accident happened and her rescue of Molly is what inspired him to become an astronaut.
* InnocentlyInsensitive:
** When giving Gordo a tour of the expanded Jamestown, he makes a comment about how Gordo must have been going crazy in the confined space of Jamestown's original configuration. He doesn't know that that's ''exactly'' what happened to Gordo, and the pained look on Gordo's face shows that it's definitely still a sore spot for him.
** While he obviously holds Gordo and Tracy in high regard, he doesn't realize that quoting from ''Love in the Skies'', the in-universe biopic about their relationship, is a painful reminder for Danny about the loss of his parents.
* KilledOffForReal: The landslide on Mars caused by the drilling accident shatters the visor on his helmet and the exposure to the Martian atmosphere kills him.

[[folder:In General]]

** He has a more amicable working relationship with Ed during the joint Soviet-Helios mission, however. By season 4 the two of them are close friends.

* FourStarBadass: Gets promoted to Admiral in the US Navy in between season 1 and 2.

* DecoyProtagonist: In a sense - due to his high billing, many suspected that he would be the new main character going forward to replace some of the older cast. Instead, he quickly became [[spoiler:the leader of the black market on Mars whereas other characters remain in the spotlight.]]

* UngratefulBastard: When her boyfriend Davey gets in touch with Margo Madison so the latter can offer her a job, Aleida's response is to begrudgingly accept the offer, but also to break up with Davey on the flimsy excuse that she can't trust him anymore, despite Davey only doing so in a desperate attempt to stop her from being deported. What makes this worse is that she immediately becomes ecstatic to be finally working at NASA, and eventually develops UndyingLoyalty towards Margo. By the 1990s, Aleida has risen to become flight director at JSC and even gets to go to the moon, whilst Davey eventually lost his job in the oil business and is left protesting outside the organisation where his ex-girlfriend now holds a senior position, which she wouldn't even have if Davey hadn't contacted Margo in the first place.

* UngratefulBastard: When her boyfriend Davey gets in touch with Margo, whom Aleida doesn't want anything to do with, her response is to begrudgingly accept her job offer, but also to break up with Davey on the flimsy excuse that she can't trust him anymore. What makes this worse is Aleida is ecstatic to be finally working at NASA, and eventually develops UndyingLoyalty towards Margo. By the 1990s, Aleida has become flight director at JSC and even gets to go to the moon, whilst Davey eventually loses his job in the oil business and is left protesting outside the organisation where his ex-girlfriend now holds a senior position. Whatever Davey's intentions were at the time is left ambiguous, but in the end it's clear Aleida never would've made it that far had he not contacted Margo in the first place.

* EurekaMoment: It's implied that Aleida finally realizes that Margot leaked the engine plans when she leaves her office, glancing back at a portrait of her with a shattered expression.

* UngratefulBastard: After her boyfriend Davey gets in touch with Margo, whom Aleida doesn't want anything to do with, she ultimately accepts the job that Margo offers her, but also dumps Davey on the flimsy excuse that she can't trust him anymore. This despite Davey seemingly having no personal stake beyond simply looking out for Aleida (he even refuses to let her come work on an oil rig with him, as he knows she's a genius and would be miserable there). What makes matters worse is Aleida is clearly ecstatic to be working at NASA, and eventually develops UndyingLoyalty towards Margo, a woman she allegedly hated. By the 1990s, Aleida has become flight director at JSC and even gets to go to the moon, whilst Davey eventually loses his job in the oil business and is left protesting outside the organisation where his ex-girlfriend now holds a senior position, which she wouldn't even have if he hadn't taken the leap for her.

* DiesWideOpen: [[spoiler: When Ed and Danielle find his corpse, his eyes remain open after committing suicide.]]

* DrivenToSuicide: [[spoiler:While the rest of the Happy Valley astronauts return to Earth a year later, Danny is not among them. It's later revealed that he killed himself during his exile in the North Korean capsule.]]

* TookALevelInCynicism: He's initially supportive of his parents' careers as astronauts, but in the years following their HeroicSacrifice he becomes jaded and cynical, developing a deep grudge against NASA whom he holds responsible for their deaths. This makes it easy for a group of anti-NASA conspiracy theorists to manipulate him into helping them seek "justice" against the organisation.

* EveryoneHasStandards: He grows to hate NASA after his parents die on the moon, but he is quite clearly very uncomfortable with some of the lengths his conspiracy theorist friends are willing to go to and is utterly horrified at the part he unknowingly played in helping them to bomb NASA. The fact they deliberately kept him in the dark about their plan indicates that they knew he wouldn't want to go through with it.
