Notably, K has a particular oddity of having no plot from shows before the 2000s: while Dangaioh and the original Mazinger Z are present, they have very little storyline significance, and all the shows more relevant to the story were made with modern computer animation. This marks a vast departure from the norm, where old-school Real Robots and Super Robots had a significant presence alongside more modern entries. Similarly, K does not reuse any sprites from the previous twogames (aside from a handful of Gundam SEED units), despite having an art style that is relatively the same.Recently, this game acquired (even more) infamy when it was found to contain certain music tracks plagiarized from Chrono Trigger and Lufia II.
Arc Welding: An example would be how ORB was funding various organizations such as the Dannar Base and the Fafner Project. This is part of the reason why the other mecha from Godannar do a Big Damn Heroes during the Invasion of ORB, though it's small compared to the reason of invading countries that don't agree with your plan is wrong.
Awesome yet Practical: However, once you learn you can attack with Raiking and Vulking BEFORE combining them with Gaiking, you can take advantage of them first before forming Gaiking the Great. Thanks to the way Combining Mecha work in K, refilling Gaiking the Great's energy will result in Raiking and Vulking's energy being restored when you decombine them, allowing you to use all of the -kings much more efficiently than should be possible. Because of this practicality, Super Robot Wars L rectified this by not allowing Gaiking the Great to separate once combined.
Bag of Holding: More like "Pouch of Holding", but King Gainer's leg pouch becomes this in its animations. What makes it strange is that King Gainer pulls its Chain Gun from its pouch every time it attacks, despite having a physical Chain Gun holstered on its back at the start of the series proper.
It's more Hyperspace Arsenal: one of King Gainer's many abilities is pulling stuff out from the fourth dimension. Yes, it didn't pull a second chain gun from its pouch, but from thin air.
Gil himselffalls in this trapin the same scenario no less, when he attempts to run off to fight another day, but the Dangaioh team kills him with the newly-unlocked Final Psychic Wave. So much for badass points, huh, Gil?
Bittersweet Ending: For a good portion of the cast. The Virtual-On units have their memories of all events in K erased as per MARZ protocol, the Fafner pilots are still slowly being turned into Festum, the Yapan Exodus is still fending off attacks from the London IMA (despite Exodus being finally legalized in their world) and the Daikyu-Maryu leaves the Earth to find a new home for the people of Darius (with the Dangaioh team taking Daiya Tsuwabuki's place).
Boring but Practical: Dann of Thursday's slashing attack. While it seems mundane, it has the "ignore barrier" attribute and is Combo Attack-capable. Although the attack has a measly weapon range of two, it can be increased via equippable parts.
Speaking of Daiya, he falls victim to this as well, with his habit of mispronouncing names: right after everyone has been warped to Darius for the first time, Daiya formally introduces himself to Ruuji Familon and Le Mi. Within seconds, he mistakenly calls them "Reiji" and "Mami", respectively: Ruuji simply gives his name again, but Le Mi is furious at Daiya's mistake.
Day In The Lime Light: The plot of K is appears focused on redeeming Cagalli, to the point where the Japanese Fan Nickname for the game is "Super Robot Wars Kagari". It basically rewrites the Gundam SEED Destiny plot as if Cagalli were the protagonist or she wasn't converted into a pathetic, mewling wretch. She does such things as hopping into a mass-production mobile suit in order to fight and defeat one of the Fafner villains (previously established in the K setting as being a hardcore badass) and basically leading the hero faction as the Big Good of the game. She does hand the Akatsuki over to Neo Roanoke, but because she's literally busy running a war, the player can plop her right back into it. She even redeems Yuna Roma Seiran and makes him into ORB's ambassador to the United Nations. Although events still stays mostly focused on the ORB side of things, thus more Kira Yamato-centric than Shin-centric, it's really Cagalli's who takes the spotlight. K also returns Cagalli's "SEED Mode" pilot skill, something which was missing in Gundam SEED Destiny.
Demoted to Extra: Many characters from Godannar only appear in intermission scenes; their respective mecha don't even appear at all.
Enemy Mine: In a rare case, very, very few of the enemy factions actively work together for long periods of time. Most alliances between them in K are short-lived. The only recurring one is Gil-Barg, and considering how often he makes life miserable for his allies, you have to wonder why they keep helping him.
For the record, the Edax do try to reason with other enemy groups at multiple points in the game. Sometimes, they gain temporary alliances with them (such as one with Emperor Jin's forces), while other times the enemy factions (such as the Jama Kingdom and The Claw) blow off the Edax outright.
Glass Cannon: Godannar machines hurt like hell when they get up to speed. Unfortunately, they're very easy to hit and have ridiculously thin armor. The Gundams, King Gainer and the Jeegs are similarly not as robust, but hit like trucks. The Brownie, however, is a textbook example in K.
Guide Dang It: As usual for SRW, knowledge of the component series is critical to getting secrets. Destroying the Diablo of Monday with the Dann, for example, is self-explanatory...if you've seen Gun X Sword.
Even then, Gun X Sword throws one of the weirdest curveballs ever with its secret. To recruit Michael and Fasalina, you have to use Van to destroy the Original Seven and The Claw before taking down the aforementioned secret pilots. Sounds fine, except Priscilla must have a combat encounter with Carossa and Melissa to complete the requirements on the scenario where Van must kill Woo. Why? The only possible connection comes from a single line of dialogue from the original series where Priscilla express grief over Carossa and Melissa's deaths. The player has absolutely no heads-up about this part and it's easy to miss without a guide to help.
Fafner also takes this to insane levels. It's an all-or-nothing secret with multiple route splits, kill requirements and in-mission decisions you have to get exactly right. Oh, and the first step? It relies on upgrading the Mark Elf so that the Mark Sechs will inherit the upgrades and have attacks which, with Save Scumming, might be enough to kill the Festum. Good luck figuring that out on your own.
Lord British Postulate: Lu Cobol's first machine Gustadio retreats once you reduce it to 50% of its HP. It's actually possible, through very, very careful manipulations of Spirit Commands, attack damage levels and a Rust Hurricane to destroy it.
Mighty Glacier The El Dora Soul can turn into this if properly upgraded.
Name's the Same: When Tangram and Daimon introduce themselves, upon hearing the latter's name, everyone gives a look towards Daimon, the elder mechanic of the Daikyu-Maryu. This includes Daiya, who has been working with Daimon the engineer for most of the game. He reassures the team that the Daimon they are speaking with has nothing to do with him.
Perspective Flip: As the cover might tell you, you see the entire Gundam SEED Destiny plot solely from Kira's side. Even the Attract Mode has Shinn on the enemy side! Since most of the show's plot is glossed over, and you get Shinn and Lunamaria immediately afterwards (Gundam SEED Destiny's plot begins on Scenario 14A and ends on Scenario 19), most, if any, complaints aren't all that vocal.
Plagiarism: One of the themes against the Edax generals had a familiar echo to Magus' boss battle music from Chrono Trigger; in fact, it wasn't just a coincidence - it sounded practically the same. Suffice to say, it didn't end well for the composer.
One of the scenario map themes is a shameless ripoff of "For The Savior" from Lufia II, just with some reverb and a mildly tweaked tempo.
It got so bad that Banpresto and Namco Bandai openly apologized for the plagiarism to their fans.
Plot Hole: There are quite a number of them laden throughout the game's backstory that almost steer into Fridge Logic territory. For the most part, a lot of the holes originate with backstory conflicts. For instance, the "War of the Titans" (what kickstarted Godannar) is explained in such a way that it gives the impression that the entire cast of Godannar should be 40 years older than they actually are. This is because of the connection to the sealing of the Jama Kingdom, as it took place about a decade before the War of the Titans, which itself was supposed to be 50 years prior to the start of Koutetsushin Jeeg. Either the script writer got lazy or did not properly check to see if there would be conflicts in the history.
Put on a Bus: The majority of the plot of Gundam SEED Destiny and its characters, the non-Dannar Base pilots, most of the one-shot villains from Gun X Sword, including Joe Lutz and Hayeta, who are in fact somewhat important to said series' storyline.
Ship Sinking: For what's probably the first time ever in SRW, a CANON ship - from Overman King Gainer - gets torpedoed. K unties the strangling red string around Adette and Gauli's necks and keeps Adette and Yassaba together.
Shout-Out: The overture of the fourth movement of Antonín Dvořák's Ninth Symphony in E minor is played as a reference to Daiya's voice actor, who also had this music playing for him when he defeated the Big Bad in one arc of One Piece.
There Is No Kill Like Overkill - Solvrias Rex's "Regret Buster" not only punches the enemy, but launches it into space, fires a beam at it, rides inside the beam, tears a hole inside the enemy (most likely to the sub-atomic level or another dimension based on the structure) and destroys it from the inside out.
The Virus: The Insania Virus; story-wise, the fact that Kouji Tetsuya can be sortied in scenarios and not be infected with the virus, despite being injured and benched for a good amount of the Godannar plot, raises questions. Likewise, as the Insania Virus specifically targets hotblooded male pilots, no other pilots in the playable roster are seemingly affected by it. Hopefully, Banpresto sorts this problem out the next time Godannar reappears.
Unstable Equilibrium: Achieving an "ace bonus" in K grants +10 to all stats for each 100 kills a pilot has, up to +100 for 999 kills. This can very easily transform an already powerful character like Van into an unstoppable One-Man Army, especially since the game's imbalanced Combo Attack system allows a single character to rack up kills really quickly.
