Code Prime
Code Prime - R1: Rebellion
- In addition to the cast from Prime, Ironhide is a member of the crew of the Ark, as was the case in Generation 1. Similarly, Skywarp and Thundercracker are part of the Nemesis Crew.
- Also, Ironhide was originally intended to be in the Prime cast but ended up getting dropped because of the film Ironhide's death in Transformers: Dark of the Moon.
- Thundercracker and Skywarp were also both planned to appear in Prime, but they were replaced with Dreadwing and Skyquake respectively.
- Just like with his film counterpart, after being introduced by Optimus, Ironhide startles Lelouch by pointing his Energon cannons at him, quipping, 'You feeling lucky, punk?'
- Optimus explains to Lelouch that the Autobots learned human languages from studying the Internet. This method was also used in Transformers.
- Kallen and Ohgi's first meeting with Zero and the Autobots in an alleyway is reminiscent of Sam and Mikaela's first meeting with Optimus Prime in Transformers.
- The Autobots and the Purebloods' Mexican Standoff is pretty much reminiscent of the confrontation involving Ironhide and Sideswipe vs. Crankcase and Crowbar from Transformers: Dark of the Moon.
- Optimus' Armor-Piercing Question to Suzaku is a deliberate reference to his question to the Secretary of Defense in Transformers: Revenge of The Fallen.
- In Chapter 6, Starscream tries looking up information on the net on Zero and Optimus, decrying it as "A trillion gigabytes of data, none of it useful!". He made the same remark in the Transformers: Prime episode "New Recruit".
- Megatron allying with Cornelia by claiming that Optimus was spreading slander about the Decepticons is clearly a reference to Bumblebee, where Dropkick and Shatter do the same.
- Rai takes a page out Sam Witwicky's book about 'researching the link between being a Britannian and brain damage' whilst defending the Japanese hot dog seller from five Britannian punks.
- In the vein of the usage of high-heat sabot rounds in Transformers, the Autobots and Black Knights utilize super-heated magnesium rounds as Knightmare ammunition as a counter to Cybertronian armor.
- At the end of Chapter 15, Megatron utters "Let the slaughter begin."
- Megatron's assistance of Charles and V.V. mirrors his interactions with Isaac Sumdac in Transformers: Animated, albeit here, he's more honest with his royal ally about who he is.
- Bumblebee shooting at Villetta to save Lelouch and Shirley is very similar to when Optimus saves Cade Yeager from Harold Attinger from Transformers: Age of Extinction.
- Mao briefly considers trying to get Shirley to kill Zero via manipulating her into doing so in revenge for her father, which is exactly what he tried in canon. Here, though, he realizes she loves Lelouch too much to do so and instead just chloroforms her and uses her as bait and leverage against Lelouch.
- Shirley's introduction to the Black Knights and the Autobots is lifted almost verbatim from Prime where Jack introduces his mom June to Team Prime.
- The Nemesis crashed on the Earth's moon in the first chapter and serves as the Decepticons base, just like the Mini-Con ship served as their base in Transformers: Armada.
- Lelouch uses his Geass on Cornelia in Chapter 22 to obtain information on all of Britannia's military operations in Japan. In the episode this was based on, Partners, Megatron was worried that the Autobots would acquire all of the Decepticons' knowledge by capturing Starscream since Airachnid left the former behind.
- Mao getting carried off by Shockwave for dissection in Nunnally Held Hostage pretty much mirrors Silas/CYLAS's eventual fate in the Transformers: Prime episode, The Human Factor.
- Shirley's actions in Chapter 24 pretty much mirrors Miko's in TMI, the difference is the former's resulting from a desire to contribute more to the Autobots/Black Knights, unlike the latter's desire for excitement.
- Similar to Jet Optimus's line, Kallen inwardly remarks about Starscream's name after Arcee shoots him down screaming.
- Monica's Knightmare is the Florence - her frame from Code Geass: Oz the Reflection.
- Nonette's Knightmare, the Galeschin, was originally the Lancelot Club. This frame first appeared in Code Geass: Lost Colors and was made Nonette's canon frame in Oz The Reflection.
- Megatron controlling the Decepticon Pretender drone disguised as Euphemia in Chapter 32 to carry out the SAZ Massacre is reminiscent of the Generation One episode A Prime Problem, where Megatron created a clone of Optimus Prime to lure the Autobots to their doom. It also calls to mind Alice, the human-sized Pretender drone used in Transformers: Revenge of The Fallen.
- During the SAZ Massacre, Optimus's takedown of seven Sutherlands with one circular move is reminiscent of his sweeping takedown of the Infernocons in Transformers: The Last Knight.
- Megatron has Hardshell kidnap Milly, Rivalz, and Nina, with the implication he intends to use them as bargaining chips, just like the Decepticons did with Miko, Raf, and Jack in the Season 2 episode of Prime, Regeneration.
- Just like in Transformers: War for Cybertron, Chapter 33 has Megatron declaring his intent on a full-scale assault onto a capital, along with wiping out its corrupt leader and his empire. In this case, Pendragon, Charles Zi Britannia, and the Britannian Empire itself! All complete with the crushing of the displayed hologram!
- The above scene also calls to mind both the Decepticon assault on Chicago (with the Decepticons assaulting a major human city) and the Transforms Prime Season 2 finale, Darkest Hour, where he launches an assault on Jasper using the Nemesis.
- When Dreadwing joins the Autobots, he has Ratchet place a bomb in his head that the Autobots can detonate if he betrays them. This was the same method Jetfire had used on him when he joined the Autobots in War for Cybertron: Siege.
- When leading the attack in Chapter 34, Megatron borrows a line from his Transformers: Animated counterpart as he commands the Decepticons to "Transform and Rise Up". The content of the speech, meanwhile, is clearly based on the one he gave in Darkest Hour from Transformers: Prime.]]
- [[spoiler:Dreadwing's final words to Suzaku, Euphemia, and Cornelia before his death mirror Impactor's dying words to Ratchet.Dreadwing: Thank you... for showing me... light.
- Lelouch's situation in the final chapter, which is slowly dying from being exposed to Megatron's Dark Geass, is similar to One Shall Fall when Megatron poisons Raf with a Dark Energon shot from his cannon.
Code Prime - R2: Revolution
- The Knights of the Round’s attempt to retake Britannia is lifted directly from the attempt against Emperor Lelouch, albeit with Megatron and Schneizel being their opponents here, and Anya/Marianne taking Monica’s place as the fourth Knight of the Round in the assault (though she survives unlike Monica). Dorothea and Bismarck even have the same last words when Devastator kills them.
- Just like when Transmetal Optimus Primal was fending off Megatron and the Predacons with a shield and returning fire in the Season 2 Episode Coming of the Fuzors (Part 2), it's Bruticus' turn to take that honor, with Alicia Lohmeyer and the Pacific Fleet on the receiving end of the counterattack.Bruticus: My turn. (unleashes his flamethrower)
- T-AI has been created and appears in the first chapter.
- Euphemia's Black Knight uniform is the same as C.C.'s from the canonical R2.
- The Autobots and Black Knights having converted the Ark into an underwater city brings to mind the oceanic Cybertron City from Transformers: Energon.
- Lelouch's new Zero outfit, which is armored, is based on his Zero Armor from Nightmare of Nunnally.
- Lugnut, who debuts in the first chapter, was originally planned for Prime as a loyal Decepticon bruiser, but the show creators used Breakdown instead as they wanted another land-based Decepticon besides Knock Out.
- Milly's attempt to assist the Research & Development team, leading to her, Rivalz, and Shirley being trapped in the Shadowzone, is played pretty much like what happened with Jack, Miko, and Raf in the Prime Season 1 episode, Shadowzone.
- While Suzaku doesn't become the Knight of Seven, his Black Knight uniform does resemble the uniform of a Knight of the Round.
- Knock Out name drops Fortress Maximus at the end of Chapter 2. His phrasing implies that this story's version is a structure like in Animated instead of a living Cybertronian like other continuities.
- When talking about Combiners, Lelouch suggests a hypothetical Combiner made of Bumblebee, Grindcore, Strongarm, and Sideswipe.
