History TearJerker / Invincible2021

* Allen the Alien reveals that the Viltrimites destroyed his planet and he was born in a breeding camp and never knew his father. Mark [[AbusiveParents feels jealous]].

** Mark throughout this season has a constant aura of sadness around him. From the way he flies and the way he interacts with his friends, you can tell that he's just sort of there. While his disposition does brighten up a bit more throughout the season, it's very telling that the guilt along with the PTSD of [[TraumaCongaLine watching his father kill thousands of innocent people, call his mother a pet (and basically say his feelings for her amounted to almost nothing), and nearly beat him to death while telling him he's replaceable]] have had a profound effect on him.
** Debbie, as much as she tries to hide it, can't move on from the hurt and while some such as Olga are able to realize that there was no way for Debbie to have known Nolan's true nature, others like Theo only compound her guilt. Made worse by the fact that for the most part she's managing all this on her ''own''. Mark at the very least has Amber, William, and Eve to help him through this. [[HopeSpot But the one chance Debbie does get to finally let her emotions out in a support group]], [[YankTheDogsChain she's shunned and told not to come back.]]

* After the introduction of one of the evil Invincibles and Angstrom Levy, we're reunited with the main universe Mark as he goes on an OnPatrolMontage set to "Karma Police" while continuing to grapple with the devastating battle with his father in the last season. It ends with Mark having a traumatic flashback to all the carnage while witnessing a bank robbery in progress, showing just how Nolan had affected his worldview.
* Angstrom's meltdown at the end of the episode after the incident that accidentally fused him with his alternate selves, where he starts ranting about how he now has all their memories of the loved ones that the alternate Invincibles have slaughtered, resulting in him vowing revenge on Invincible and setting him down on the path to becoming his ArchEnemy.

* The segment on Martian Man becomes quite sad as it shows what a NiceGuy and FriendToAllChildren he was. It makes it all the more tragic that he was killed by Omni-Man.

* Mark arrives to the Thraxan homeworld and discovers... Nolan was the one who recommended the signal. The reunion begins with a tense stare down, moves forward into Mark hugging his father for the first time in a while... [[AdaptationDeviation and then we see a big departure from the comics]]. Whereas in the original issues, Mark begged his father to come home, here he assumes that Nolan used the Thraxans to coax Mark into meeting him because he knows that his son wants nothing to do with him. Nolan knows he has every right to make that assumption and tries to clear things up, but [[NotHelpingYourCase the language he uses to describe his sins]], calling them "mistakes", proceeds to disgust Mark [[CallingTheOldManOut so thoroughly that he disowns him to his face]] and moves to leave. He only hears Nolan out because the man refuses to take "no" for an answer, not even because of his usual ways, but because [[AintTooProudToBeg he is desperate for genuine help to save the planet he's calling a new home]].

* The Viltrumites arrive and slaughter most of the Thraxans with Mark and Nolan only barely able to save Oliver and Andressa.
** In their fight, when Lucan accuses Nolan of [[NoTrueScotsman dishonoring]] [[TheEmpire the Viltrumites]] and that he "deserves death", Nolan, after spilling Lucan's guts and impaling him, simply responds "I know." Given Nolan's ConflictingLoyalty, [[DoubleMeaning it's likely that]] he agrees with Lucan not just for his disobeying of Viltrum, but also because [[IAmAMonster of all the horrible things he did on Earth]]. The worst part is that, due to him denying his attachments to the slaughtered Thraxans, he may not even be fully aware [[FreudianSlip of his own remorse of the latter]] at that moment.
** Just the fact that Nolan is actually heartbroken and visibly sad about all their deaths. While on Earth he tried to play it off through excessive cruelty, here he realizes that he has started to care, and it angers him to the point that he nearly chokes Mark [[EvilCannotComprehendGood to find out why he does]]. To him, [[TheSocialDarwinist as a Viltrumite]], he should see them the same way he supposedly saw the humans he protected for 20 years. Mark only has [[ArmorPiercingResponse this response]]:

** Even Mark himself, despite his misgivings with his father, is appalled by the destruction, recognizing Nolan's pain at seeing the Thraxans killed and trying to gently call to him. When he tells Nolan that his feelings for the InsectoidAliens is what he should have felt on Earth, it sounds like he's not only still frustrated with his father's stubbornness and past actions, but also trying to get him to understand that such feelings are natural and that he shouldn't keep denying them, which is what seems to finally make it click in Nolan's head that [[HumanityIsInfectious he's changed from the conqueror he once was]].
* Eve tries to take her frustrations out on Kill Cannon when he tries to rob the old Teen Team headquarters. As she elongates the fight due to this, she reflects one of his shots in a way that ends up knocking a car off the bridge they're fighting on, and he disrupts Eve's attempts to rescue the people in it. She pulls them out of the water, but it's ambiguous if they survived. Afterwards, Eve [[MyGodWhatHaveIDone is distraught]] at letting her emotions cause such a thing and returns via bus to her parents' house.

** Despite the rocky nature of their relationship, Atom Eve can't help but shed tears for his, and possibly all other members, state, it really did affect her for a while.
** Dupli-Kate's unfortunate death and funeral, attended by all able bodied members, Mark and Eve. This leaves The Immortal completely destroyed, as he really did love her, anguishing over his belief that they'd have more time together.

* After feeling like Mark's double life is putting too much strain on their relationship, as well as making her feel guilty about missing him when she knows what he does is important, Amber considers ending it. Right when they were enjoying time together, Amber's decision ends up being made when she's threatened by Anissa. She only has a brief moment to be consoled by Mark from her NearDeathExperience before he's forced to leave and speak with Anissa under the threat of a massacre, and Amber's [[TroubledFetalPosition alone in her dorm room]] by the time Mark returns. She states having felt that her life was insignificant compared to his, but even in finding contentment with it, she now feels like a tool to be used to threaten him. And for Mark's part, he fears what he might become if something did indeed happen to her, and how it may turn him into something like his father. Realizing it can't work, they agree to break up.
-->'''Amber''': ''[tears flowing]'' This isn't going to change, is it? I can't live in your world. I want to. I really tried, but I can't. So how does this ''work'', Mark?\\
