History Heartwarming / MobileSuitGundamSeed

* Athrun and Cagalli growing closer over the course of the series, from ennemies to friends and eventually falling in love with each other (plus the fact that they are a Coordinator/Natural couple):
** When they are both stranded on a deserted island in their first encounter, they try to kill each other. But they did not and they spent the night talking (albeit harshly) about their motivations for fighting in the war, this is the first time Athrun opens himself to someone else. Athrun even offering part of his food to her. When she gets his pistol, she choose to not use it in the end and when she carelessly throws a charged gun, Athrun did not hesitate to protect her despite her trying to killing him a second time.
** Their second encouter, after Athrun fated duel to the death with Kira, was filled with TearJerker. But it also has Cagalli choosing to spare him, not wanting to continue the cycle of revenge and she gives her Haumea amulet to protect him, even after knowing he has killed Kira (as they thought). Cagalli's words has marked Athrun a lot, he will reference the encounter in the sequels. ''Anime/MobileSuitGundamSEEDFreedom'' shows that Athrun is still wearing the Haumea amulet.
** After Athrun is shot by his father, he says to her that her amulet has protected him which she appreciates. In the following breifing, he is missing and Cagalli goes to confort him. Keep in mind that she has lost her own father very recently and is obviously still pained by that but she did go comfort him anyway. Athrun clearly notices that and he hugs her, accepting her selfless gesture but also to comfort her as well.

* Andy Waldfeld's entire story arc. After being forced to fight against Kira and losing which causes him significant permanent injury and the loss of his love Aisha, he's retrieved by Patrick Zala's men, healed to the best of their ability (he still needs a cane to get around) and placed in charge of their top secret warship Eternal that's equipped with the powerful Meteor battle platforms and told by Patrick that they'll use them to make the Natural's pay. You'd expect Andy to swear bloody vengeance on Kira and the Earth for his loss as these stories would usually go. Instead he decides those events just soured him on the whole war and he sees people like Zala as the real problem and not the guys out fighting it so he joins the Clyne's and hands the Eternal over to them. When he meets Kira again he tells the boy he has no hard feelings and blames the war, not him and would go onto be one of Kira's most reliable and trustworthy allies from then on.

** The show's version still counts to some degree. From a meta perspective, the purpose of the scene was to give closure to Flay's story arc and illustrate to the audience what she wanted to say to Kira even though he'll never hear it and it does this perfectly. Even though her words never truly reach him, Flay shows just how much she now cares for him and how much she wished she could make things right after everything she put him through. And this is even bookended by her repeating the words she said to him when she started manipulating him, but this time with true and complete sincerity.
---> '''Flay:''' "I'll protect you. My true feelings will protect you."

--> ''[[MutualKill Yuki shoots back at Patrick, killing him]].''

---> '''Patrick:''' What's the delay!? Hurry! It'll all be over when we finish this!
---> '''Yuki:''' Mr. Chairman, we've already won the battle! If we fire, we'll wipe out ''half the life on Earth''! There have already been enough sacrifices!
---> ''Patrick shoots him with a gun.''
---> '''Patrick:''' [[TheParanoiac They're out there! They're still out there! Why would you even suggest that we not fire it!? We must fire it again! Before they have a chance to retaliate! The enemy must be annihilated! Why won't you all understand that!?]]
---> '''ZAFT Officer:''' But Your Excellency, our forces are still in the line of fire!
---> '''Patrick:''' [[WeHaveReserves All of our soldiers are fighting for one thing - victory! I'm sure they're prepared to pay the cost!]]
---> '''ZAFT Officer:''' Sir -
---> '''Yuki:''' Y-you bastard ...
---> ''[[MutualKill Yuki shoots back at Patrick, killing him]].''

* Mu La Flaga [[spoiler:[[HeroicSacrifice throwing himself into giant energy beam]]]] to save his crew, or more importantly to him, his lover.

** Cagalli and Kira have a few dramatic hug scenes. The strongest of which is probably when The Archangel docks in Orb for the second time, and Cagalli rushes aboard to find Kira and immediately jumps into his arms. Of course this is as far as they ever go since they're [[spoiler: brother and sister]] but even so their moments are rather moving.

* In ''Gundam SEED'', after Kira defeats [[spoiler: Andrew Waltfeld and his lover/co-pilot Aisha]], the two of them quickly jump out of their seats and into each others arms; perhaps as much heart-rending as heartwarming as the mobile suit explodes immediately afterwards, presumably killing both of them. That they wanted nothing more than to hold each other at the end so it certainly qualifies.[[note]] Andrew survives, and says that Aisha protected him at the cost of her own life, which makes it count even more. [[/note]]

* During the Battle of JOSH-A, the Archangel discovers that the top brass has already evacuated their base, and that they left the remaining straggling Earth Alliance forces behind as bait to lure ZAFT forces close enough for a hidden self-destruct system to slaughter everyone, ally and foe alike. [[spoiler: Upon hearing this, Kira [[MidSeasonUpgrade (now piloting the Freedom)]] opens a channel to ''both'' sides, urging everyone to evacuate; Yzak isn't having any of it, and continues to bear down on him. After a brief struggle, Kira is poised for a killing blow on Yzak's cockpit and taking revenge for a civilian shuttle he had been protecting earlier in the series (Yzak had shot it down, thinking it was full of escaping Alliance soldiers). Instead, in a split-second decision, Kira angles his beam saber downward, slicing the Duel's legs off and kicking it away to be picked up by a retreating ZAFT suit. He very well could have simply taken Yzak's life there [[WhatYouAreInTheDark and no one would know it was for simple vengeance]], but with his renewed outlook and desire to simply ''end'' the fighting, he chose not to. ''Someone'' has to end [[CycleOfRevenge the cycle,]] after all.]]

* [[ParentalSubstitute Ray Yuki]], full stop. The man pays more attention to Athrun ''than his own father'', and willingly shoots his own boss before [[DyingMomentOfAwesome bleeding out from his wounds]], when he realizes that Patrick firing GENESIS ''at the entire Earth'' will kill countless innocent civilians, '''especially when they've technically won the war'''.

Patrick shoots him with a gun.

Yuki shoots back at Patrick in a [[MutualKill]].

* Flay Allster hearing Kira's voice and being happy that he's ALIVE. It shows how far she's come from wanting him dead.

** Cagalli and Kira actually have a few dramatic hug scenes. The strongest of which is probably when The Archangel docks in Orb for the second time, and Cagalli rushes aboard to find Kira and immediately jumps into his arms. Of course this is as far as they ever go since they're [[spoiler: brother and sister]] but even so their moments are rather moving.

* In ''Gundam SEED'', after Kira defeats [[spoiler: Andrew Waltfeld and his lover/co-pilot Aisha]], the two of them quickly jump out of their seats and into each others arms; perhaps as much heart-rending as heartwarming as the mobile suit explodes immediately afterwards, presumably killing both of them. That they wanted nothing more than to hold each other at the end, however, certainly qualifies.
** Actually, [[spoiler:Andrew survives, and explicitly says that Aisha protected him at the cost of her own life.]] Still counts, of course.

* The Manga adaptation's version of Flay's ghost appearing to Kira. Unlike the show, the manga shows Flay's ghost actually appearing to Kira and him acknowledging it. Ultimately Flay apologizes for her actions, embraces Kira and encourages him to keep fighting and not give up. Compared to the show (where Flay never gets to make amends) the manga manages to give her some small measure of redemption for her actions.

* During the Battle of JOSH-A, the Archangel discovers that the top brass has already evacuated their base, and that they left the remaining straggling Earth Alliance forces behind as bait to lure ZAFT forces close enough for a hidden self-destruct system to slaughter everyone, ally and foe alike.

** The next time he sees her, he asks what her boyfriend was piloting at the time of his death. When he learns it was a [[CoolPlane Skygrasper,]] he concludes, with relief, that "it wasn't me." He then offers Mirallia the chance to kill him, if that's what she came to his cell to do.

* After Kira's first major battle in the Strike, Mu is called over to the Strike as Kira is refusing to come out of it. As Mu approaches and then overrides the hatch controls, he angrily calls out Kira's name, as if he's a SergeantRock about to chew out the NewMeat. But when he sees inside and realizes Kira is nearly catatonic due to combat stress, Mu immediately switches to a much gentler voice and BigBrotherMentor demeanor, speaking encouragingly to Kira and helping him out of the cockpit.

* Generally any scene involving Lacus and Kira interacting could go on here.

* The 1 on 1 scene where Athrun is being promoted within ZAFT after destroying the Strike and Yzak is acting unpleasant. Instead of making it harder for him, Athrun apologizes for their lost comrades and thanks him for his service. Yzak seems to take it well and tells Athrun not get himself killed, so they can keep their rivalry.

* Lacus comforting Kira after he finds out the truth about his origin, telling them that he still has a right to exist as everyone else does. It was something that she learned from her own mother who she barely knew since her childhood. Regardless of what you think or feel about Lacus, this was one of her highest points in the series.

** Cagalli and Kira actually have a few dramatic hug scenes. The strongest of which is probably when The Arcangel docks in Orb for the second time, and Cagalli rushes aboard to find Kira and immediately jumps into his arms. Of course this is as far as they ever go since they're [[spoiler: brother and sister]] but even so their moments are rather moving.
* Any of the dramatic kiss scenes. Mu and Murrue's scene (in which Mu admits he disobeyed orders and saved the Arcangel from destruction simply because he loved Murrue) and Athrun and Cagalli's scene (where they vow to protect one another and finally end their SlapSlapKiss with, obviously, a kiss).

** Nearing that same; Yzak defending Dearka, [[HoYay saving his life]], despite their recent fighting.
