History Heartwarming / CodePrimeR1Rebellion

** The Black Knights and Autobots cementing their loyalty and friendship to Lelouch.

C.C. does so with the words Lelouch used when they made their contract.

*** C.C. actually cries TearsOfJoy at the realization that Optimus could fight off Megatron's power. A feeling stirs in her in that she hasn't known for a long time: [[HopeBringer hope]]. [[FridgeBrilliance Which also completely proves Alpha Trion's point]].

** Lelouch's friends and allies unite to save him from Megatron's Dark Geass.

** C.C., while making a contract with Optimus, outright “begs” the spirits of the Primes to allow it, because she’s started becoming real friends with the Autobots and Black Knights, and wants to avoid losing them.

** Shirley manages to talk Nina out of going on a RoaringRampageofRevenge for Euphemia's sake, helping her realize the evil of Britannia and the Decepticons, and that Euphemia and the Black Knights want to help people.

** Optimus' interactions and relationships with Euphemia and Nunnally count as well. Overall, Optimus gives the [[RoyallyScrewedUp three imperial siblings]] a chance to experience an actual warm father figure.

** Cliffjumper doesn't show any fear while [[TakingYouWithMe shoving Luciano into a generator]], instead giving Arcee and Kallen [[GoOutWithASmile a parting smile]] that remains even after his death. He even promises to say hi to Naoto and Tailgate for them.

** Dreadwing realizes his T-Cog is too damaged for him to escape the deposit's blast radius, so he stays behind to fend the Insecticons until detonation, all while sending his final thoughts to Suzaku, Cornelia, and Euphemia.
--->'''Dreadwing''': [[LadyOfWar Cornelia li Britannia]], you and I may not have agreed on everything. But you are an honorable warrior, one who cares deeply for your comrades as well as for your family. I am proud to have fought beside you. ''[...]'' [[AllLovingHeroine Euphie]]... you are a kind soul... one who wishes for all people to live happy lives, regardless of their differences. Continue to strive for the peaceful future you wish for, and never let go of that kind heart you hold deep inside. ''[...]'' [[BashBrothers Suzaku Kururugi]]... You ''are'' my brother. You have my flaws, but I wouldn't trade you for any other. You wish to atone for your past sins; be sure that you do, by living for the sake of those you care for. For your friends' sake, for your loved ones' sake, don't abandon them, not now, not ever. ''[...]'' Thank you... all of you... for showing me... light...

* Nearly any interaction between Lelouch and Optimus. While Optimus fulfills the ParentalSubstitute role for many characters, his relationship with Lelouch in particular shows him offering both guidance to the young, inexperienced revolutionary and someone to confide to during his most conflicting moments. Lelouch in turn views Optimus as the positive father figure he had yearned for and as a result of the [[PositiveFriendInfluence kindness and respect he was treated by the Autobots]] he actually begins to [[AdaptationalNiceGuy develop a true sense of companionship with his Black Knights]] and [[AdapationalHeroism steer away from more dubious decisions and actions, gradually becoming a legitimately nobler and heroic individual.]]

* Nearly any interaction between Lelouch and Optimus. While Optimus fulfills the ParentalSubstitute role for many characters, his relationship with Lelouch in particular truly shows how well he can bring out the best in people and how desperately Lelouch had craved a positive father figure. Lelouch in canon lacked any moral role model which had factored into some of his more morally-dubious decisions as Zero, but under Optimus' mentorship he is gradually steering away from the path he would have followed and slowly becoming a truly heroic individual.

*** Nonette makes clear her loyalty to the Emperor and Britannia will always be secondary to her loyalty to Rai. Rai returns the favor by standing by her side against Dorothea.

* Any interaction between [[LadyandKnight Suzaku and Euphemia]] as well, like in canon. Made even more sweeter is the fact that [[WordofGod the author has said]] that Euphie [[SparedbytheAdaptation will live to the end of the story.]]

* In Chapter 4, after Lelouch explains his backstory to the Autobots, how he and Nunnally were exiled by their father after the death of their mother, and Charles basically told Lelouch that [[IHaveNoSon he has always been dead to him]], all of the Autobots are horrified to hear this and completely sympathize for Lelouch, with Bulkhead, Ironhide, and Arcee even willing to Groundbridge directly to the palace and blow it all up for what happened. Lelouch is completely shocked that the Autobots are so sympathetic for him they would be willing to storm the palace for him. This is just the beginning of their partnership and friendship he has with them.

** Bulkhead and Wheeljack also offer comfort Rai as well when he feels guilty over causing the avalanche that caused Shirley's father's death, and angry over Suzaku calling the Autobots and Black Knights cowards. The two Wreckers assure him that they're not cowards, and that they'll protect everyone they can, even if they can't save some people. This strengthens Rai's resolve to not fail in protecting Shirley.

** When Cornelia reveals that she's always been envious of Nonette, [[AlwaysSomeoneBetter seeing her senior as a better warrior than herself]], Nonette is quick to tell Cornelia that [[YouAreBetterThanYouThinkYouAre she's capable of much more than she thinks of herself]]. She also tells Cornelia that she considers her as [[FriendlyEnemy a rival and a friend]], and apologizes for not being able to help Cornelia when she was abandoned by Airachnid and captured by the Autobots. Cornelia is surprised and relieved at Nonette's confession, and Euphie pulls the two of them together in a GroupHug, which they both return. Nonette than assures the two sisters than she'll be there for them if anything happens.

** There's also the part where Lelouch promises Nunnally that he won't die and he won't leave her, and that he'll make the world a better place for them both to live in with everybody else after Nunnally expresses that she can't imagine the world without her big brother, which was what she said when Lelouch died in the ''Code Geass'' finale. Here, with Lelouch becoming a better person thanks to the Autobots, Optimus Prime in particular, perhaps the siblings will be able to [[EarnYourHappyEnding live together in that better world in the end.]] Only time will tell...

** It begins with Milly saying her goodbyes to Lelouch, Nunnally and Sayoko before they leave Ashford Academy, with the siblings thanking Milly for everything she and her grandfather had done for them. In return, Milly asked Bumblebee to [[TakeCareOfTheKids look after the two siblings,]] despite not having a translator.

*** There's also Nunnally feeling Optimus's presence near her: One of hope, comfort and awe that she had never known before.

** Gino, Nonette and Monica all listen to their consciences.

--->'''Shirley''': Please! Let me help! They need me!\\

** Kallen finally comes clean with her mother, telling her that she's a Black Knight, as well as the truth about Lelouch and Nunnally. While Mrs. Kozuki is understandably worried for her daughter after losing Naoto, [[SoProudofYou she expresses in her daughter for taking a stand against Britannia.]] Kallen even properly introduces her mother to Arcee and Cliffjumper.

*** Right after receiving the message, Cecile decides to defect from Britannia as well in order to help Suzaku. Lloyd tags along as well, though it's mostly so he can keep working on the Lancelot.

** While he doesn't go into the full details, Lelouch tells Shirley about her mother's death, telling her that he knows the pain of losing a parent they love dearly, and offers to be someone to comfort her. Shirley's reaction is to cry in Lelouch's chest and accept his comfort, hurt but also relieved that she can share her grief with someone who understands her pain.
** Bulkhead and Wheeljack also offer comfort Rai as well when he feels guilty over causing the rockslide that caused Shirley's father's death, and angry over Suzaku calling the Autobots and Black Knights cowards. The two Wreckers assure him that they're not cowards, and that they'll protect everyone they can, even if they can't save some people. This strenghthens Rai's resolve to not fail in protecting Shirley.

---> '''Villetta/Chigsua''': I don't want to be that person anymore....but if I do...become her again...go ahead and do what you have to. Protect your friends, even from me.

* In Chapter 18, Kallen is conflicted about her reasons for fighting since hearing of the (apparent) death of Shirley's father. Arcee and Cliffjumper console her and encourage her to keep fighting for what's right to make sure at least the deaths of innocents are not in vain. Kallen gratefully promises that she will follow the two Autobots to the very end. Cliffjumper corrects her.
--> '''Cliffjumper:''' I think you mean, ''ride'' with us to the very end. We're your partners, not your superiors.

** It begins with Milly saying her goodbyes to Lelouch, Nunnally and Sayoko before they leave Ashford Academy, with the siblings thanking Milly for everything she and her grandfather had done for them.
