Mythology Gag/Anime and Manga/Mobile Suit Gundam AGE

Mobile Suit Gundam AGE is rife with references to the older series, thus necessitating its own page.

Mobile Suit Gundam

 * The AGE-1 stabs its first victim in the fashion of RX-78-2 stabbing a Zaku up close with its beam saber, except AGE-1 stabs the UE a few more times before letting it fall to the ground.
 * The AGE System gathers data from the battles that it fights in in order to evolve and become stronger. Not very unlike the RX-78-2's learning computer...
 * G-Exes is clearly a name made after Gundam in the same fashion as G-Saviour; its appearance is more like Nu Gundam than the Genoace Custom, too. It also has some resemblance to G-3 Gundam.
 * The way Desil fires the Gundam AGE-1's beam rifle under the arm is a direct shout out to Amuro.
 * The motivations for the  fighting against Earth Federation resemble that of the Principality of Zeon.
 * Episode 29 shows us the return of the Core Fighter.
 * The history of warfare between the two factions in Fardain is strikingly similar to the timeline.
 * The first-generation episode "Space Fortress Ambat" is near the end, just like "Space Fortress A Baoa Qu".
 * Geera Zoi calls the Diva a Trojan Horse after seeing it transform into a White Base lookalike.
 * Both the Federation Forces, Zalam and Eubas battleships bear striking similarity to the Salamis-class cruisers from Universal Century. The UE's battleships, however, are basically slightly revamped Musai-class cruisers, also from UC.
 * Beyond his similarities to Amuro Ray, Woolf's nickname of White Wolf can also be a reference to Zeon ace Shin Matsunaga.
 * The Gundam Age-2 has three times more thrust in G-Strider form than in mobile suit form.
 * The Zeydra, a red mobile suit, is three times faster than other Vagan suits and piloted by a guy wearing a mask. Also, it apparently has the ability to unleash a super-powered version of Char's infamous kick.
 * Like Zeon, the Vagan are in control of a good deal of Earth during the third arc. And their assault on the Federation stronghold was beaten off.
 * The trio of enemy pilots in Episode 31 may be a reference to the Black Tri-Stars.
 * Towards the end of Episode 33, the shot of birds flying over Rostroulan is a definite nod to the birds in flight while the White Base leaves Jaburo in the original series (oof).
 * Captain Ash seems to have adopted Char's (and Rau's) tendency to sortie without a flight suit. He also implements the Char Kick in his fight against Kio.

Mobile Suit Gundam 0083 Stardust Memory

 * Heroic Sacrifice seems to shout out how Gato went out.
 * While the Diva pilot crew are eating lunch in episode 20, it pauses for a second on Asemu's fork simply stabbed into a carrot, a subtle nod to Kou Uraki.
 * More than that, it's been stated that the relationship between Asem, Romary, and Zeheart is meant to parallel that between Kou, Nina, and Gato.

Mobile Suit Zeta Gundam

 * Just like Kamille Bidan, Asem participates in Junior Mobile Suit Tournaments.
 * One of the Federation squadrons is the "Kamil" squadron.

Mobile Suit Gundam Unicorn

 * Zeheart's arrival on the battlefield in the Zeydra exactly mirrors Full Frontal's charge in episode 2, right down to Bridge Bunny commentary and camera angles.
 * AGE-3 can use its beam saber directly from its forearm a la Unicorn Gundam.

Other UC series

 * The Genoace Custom's shield has a red wolf-head painted on it, strongly resembling the red unicorn-head on Nu Gundam's shield. Their pilots' nicknames are also similar (The Federation's White Wolf and the Federation's White Devil, respectively).
 * Vargas' barn defense team, consisting of a few engineers, a jeep, and a RPG, resemble the village militia from Mobile Suit Gundam: The 08th MS Team.
 * Still too early to tell, but in the OP, there's a mobile suit standing in front of a skull-and-crossbones banner.
 * The Vagan are not above manually pushing ships while using Mobile Suits. Ironically, while in Mobile Suit Gundam Chars Counterattack the Mobile Suits are pushing Axis away from Earth,
 * The Vagan are not above manually pushing ships while using Mobile Suits. Ironically, while in Mobile Suit Gundam Chars Counterattack the Mobile Suits are pushing Axis away from Earth,

Mobile Fighter G Gundam

 * Asemu's first scene is him making fools out of some thugs, not unlike Domon.

Mobile Suit Gundam Wing

 * The destruction of the weapons by both Euba and Zalam before the story begins, which was supposed to bring a permanent peace to humanity, is a reflection to the ending of Mobile Suit Gundam Wing Endless Waltz.
 * Asemu tries on a Veigan helmet that gives him X-rounder abilities, but at a costly price, just like the Zero system.

After War Gundam X

 * Yurin giving directions to Flit in Episode 2 is similar to Tifa doing the same for Garrod.
 * Asemu's Character Development seems to be matching up very closely to Garrod Ran's.
 * What Zeheart says to Asemu after their fight in Episode 20 resembles Carris Nautlius' "The Reason You Suck" Speech to Garrod after their first fight.
 * The first combined SigMaxiss Cannon shot was similar to Garrod's first Satellite Cannon shot.

Turn a Gundam

 * The Gundam AGE-1 rising from the haystack in Vargas' stable.

Mobile Suit Gundam SEED

 * The AGE Gundam's first sortie has it using knives as weapons, not unlike the Strike.
 * Zalam's crest is suspiciously similar to ZAFT's; While their flag is completely different, Euba may therefore be the Earth Alliance.
 * Episode 31 sees the AGE-3 Normal having trouble fighting in the desert, specifically having trouble balancing on the sand, just like the Strike did.

Mobile Suit Gundam SEED Destiny

 * Episode 31 introduces us to a three-man team with the word "Phantom" in their name (or at least the one given to them by the Federation). Phantom Pain, anyone?

Mobile Suit Gundam 00

 * Within the first five minutes of the first episode, two soldiers in Union and HRL uniforms can be seen walking by in the foreground discussing something.
 * The world of the gap between the rich, ignorant and the poor in the same colony resembles not only the world of Gundam 00, but also Real Life.
 * The uniforms for Asem's school resemble those of Celestial Being in season 2. (And Flit's military uniform strongly resembles an A-LAWS one.)
 * The AGE-3 Fortress firing all four of its cannons at once rather strongly resembles one of the Seravee's favorite moves.
