YMMV / Iron117Prime

• Improved Second Attempt: Iron117Prime is known for his amazing crossovers, and while it’s agreed that all his stories are good, it’s clear that he became more skilled and improved his story plot planning in his newer stories by improving story elements from his old stories.
  • Code Prime: The fic borrows elements from Worlds Collide (TMNT) and improves on them here.
    • Worlds Collide notoriously kills off the rest of the supporting antagonists from ATLA as soon as the Foot Clan takes hold of the narrative, effectively diminishing the antagonistic drive of the ATLA universe in the story and shifting it towards the TMNT world. The only ones still in by that time are Azula and Hama, though it's now the Foot's show. Code Prime, while it does kill off some minor villains, manages to keep more major villains from Code Geass alive and still give them some plans to do in the second cour even after the Decepticons take over. And even if much of the CG antagonists are already dead, the significant damage done by the heroes force the Decepticons to take the route pursued by the minor universe: unleashing Neo Ragnarok. This means that while the newer villains take over the story, the old villains still have some fight left in them.
    • Worlds Collide sets the ATLA universe after the events of Book 1: Water and into Book 2: Earth. This isn't necessary a bad thing, but the intention of the Turtles mentoring Aang somehow wouldn't feel connected to the story's beginning, especially since they just came and knew of the situation, leading to some Infodump from the Turtles' perspective. Here, the story begins at the very start of the Code Geass series proper, allowing the Autobots' mentorship to feel more natural and the canon to flow more naturally, and thus, much exposition is saved regarding the matter. Both J-WITCH and A Red Rose In the Blue Wind would follow this, the latter even using the same setup as Worlds Collide albeit starting earlier so as to follow Team RWBY and JNPR's character. The author even stated this in his reason for discontinuing Avengers of the Multiverse, preferring to start the story at the start of their character development.
    • The reason for Shredder attempting to take over the Fire Nation is merely "I cannot share power because I only rely on myself" which, while solid, feels more like a rather flat For the Evulz moment. Here, Megatron's motivations are more solid regarding his Pretext for War against Britannia: Charles had been planning the Ragnarok Connection behind his back for somewhat noble reasons, and Megatron, clearly not a fan of the motivation itself, decides to take over in his stead, even reworking Ragnarok in R2 to fit his overall vision.
    • While Worlds Collide massively shook the status quo by having the Fire Nation be usurped by the Foot Clan, the canonical endgame is still the same (defeating an oppressive force and restore the world to the heroes). Here, the canonical endgame for Code Geass is MASSIVELY changed due to the rise of the Decepticons, allowing for a more unpredictable and engaging story long after the midpoint.
  • However, both Worlds Collide and Code Prime improve on an older fanfic with a similar crossover premise: Transformers: Avatar Chronicles. To wit:
    • Avatar Chronicles was infamous for showing how incredibly imbalanced the Transformers world is compared to the ATLA universe. The two stories split both franchises involved (Transformers and ATLA) and gave them to much more balanced entities; it's quite engaging to see Transformers in a Real Robot setting, while ATLA is paired with the street-level Teenage Mutant Ninja Turtles, making fights more streamlined.
    • One of the most controversial scenes in Avatar Chronicles was Megatron firing into Aang and forcing him out of the Avatar State, largely because it broke Willing Suspension of Disbelief and even then, Aang would have been completely obliterated no matter what had happened. Worlds Collide rectifies this by having Aang fight the Shredder and ending with him being stabbed by the latter's claws, in effect mortally wounding him and still leaving a body behind to contiue the story. Meanwhile, Code Prime has all instances of Megatron firing on humans with his fusion cannon a guaranteed fatality; the only reason V.V. survives these attempts is due to the innate immortality of his Code (something established in canon), and one of the most iconic scenes in the story is Megatron firing his fusion cannon on Charles zi Britannia and subsequent chapters making sure that he was indeed killed off.
    • The fanfic was notorious for introducing so many characters from Transformers in large increments into the Avatar universe in the early chapters, making it hard for the story to follow just who's who is in the fanfic. TMNT's roster is rather small and much of the story focuses on just the Gaaang and the Turtles, with the only ones following being more major characters. Meanwhile, Code Prime R1 focuses solely on a reasonable set of Transformers characters, the new additions it made throughout its story are rather small but all playing major roles, and when it's time to start bumping up the cast, it was done in R2, right after Megatron had just summoned reinforcements to obliterate Britannia and making it clear that the fight has just escalated.
• Spiritual Successor:
  • Tangled With Ninja: Borrows a lot of elements from Frozen Turtles, down to the protagonist archetypes, the overall plot and the conflict.
  • Code Prime:
    • Larger-scale battles, Fix Fic elements, Canon Welding, characters being spared or killed in the adaptation are all prevalent in the fic. Clearly, Iron117Prime wants to put Transformers into Super Robot Wars. It helps that Code Geass shows up often in various games, as well as the various Brave Series anime (which was developed thanks to Transformers). Adding to this is the fact that both T and 30 were released during the series' publication period, the latter including the series. To top it off, the game that predates the fic earliest, X, ironically had the Code Geass characters being the ones helping fix the story of Cross Ange (with Lelouch playing a significant role), as well as the presence of the Gundam Wing characters, which gets homaged in the story a fair amount (and coincidently shares its world with Code Geass in X's story).
    • Special points go to the Spared by the Adaptation factor. Euphie and Shirley are spared in Saisei-hen, but come with somewhat questionable methods. Euphie only appears at the end unexplained and requires a Golden Ending to do so. The same is true of Shirley's fate, requiring a set amount of points to ultimately spare her. Rolo dies both in-story and in Saisei-hen. After that entry however, most of the games featuring Code Geass never opt to start from the beginning and leave all three dead (although with 30 choosing the film continuity, this means Shirley is alive). And this would be the same series to follow through Rayearth's storyline through from beginning to end.
  • J-WITCH Series: With the large amount of MacGuffin hunts and the overarching conflict spanning generations, and the main protagonists being magical girls and martial artists, one wouldn't be surprised if Iron117Prime is doing his own take on Cardcaptor Sakura.
  • A Red Rose in the Blue Wind: The crossover is a throwback to the Frozen Turtles series. Both the worlds of Sonic and RWBY are established as different dimensions, much like how Arendelle and New York are different in the setting. One franchise is composed of a World of Funny Animals opposing a human antagonist hell-bent on destroying them all. The other is patterned after fairy tales, but it's more of a motif rather than a direct adaptation.
