History Characters / AceCombat04ShatteredSkies

[[folder:ISAF]]

The Independent States Allied Forces, an international military alliance of Usean countries opposed to Erusea's expansionism.

* TheAlliance: Multiple nations united against Erusea, though specific borders are not shown in briefings, and instead limited to "ISAF territory" and "Erusian territory".
* BackFromTheBrink: In the beginning of the game, ISAF has lost most of its territory due to Stonehenge blocking their air force from operating in most of the mainland. Their only territory shown in the initial briefing include North Point, various other islands, and one mainland territory: St. Ark. With the aid of Mobius One, ISAF eventually liberates all of their territory and even takes over the Erusian capital of Farbanti.
* FantasyCounterpartCulture: Very similar to the real-world North Atlantic Treaty Organization, another military alliance with a four-letter acronym. The ISAF and NATO flags are both white emblems over blue backgrounds, highlighting the similarity.

[[folder:Mobius One]]

One of ISAF's fighter pilots, and later their top ace. Mobius 1 returns as the playable character for ''Ace Combat 7''[='=]s VR missions, now affiliated with the IUN and fighting another Free Erusea movement in 2014.
----

[[folder:Federal Republic of Erusea]]

A large western nation of the Usean continent with a ultranationalist government and the main opposing force for the game.

* TheEmpire: By the beginning of the game, they have secured most of the Usean Continent, and nearly destroy the last remnants of ISAF in the first mission.
* ANaziByAnyOtherName: It's ambigous, since the inner workings of Erusea's government are never seen. Multiple characters, including ISAF allies and at one point the narrator, call them "fascists" as an insult. The narrator mentions a "secret police", and local law enforcement being replaced with Erusian military police.
* TheRemnant: The briefing for the final mission describes the enemies as a "group of young Erusian officers", who have presumably [[spoiler: ignored Erusea's surrender in their act of taking over Megalith]].
** A more clear-cut example, called Free Erusea, are the main enemy of [[VideoGame/AceCombat5TheUnsungWar Operation Katina]].
* WouldNotShootACivilian: Averted several times during the story. At one point, several fighters are sent to shoot down two passenger planes because they both have defectors onboard. Later on, bombers are also tasked with attacking a just-liberated city with the intention of destroying the allied forces there without any regard shown for civilian casualties.

[[folder:Yellow 13]]

Erusea's top ace, and leader of Yellow Squadron.

* AcePilot: Mobius One's most formidable adversary, with sixty-four confirmed kills in his first appearance. Makes sense since he was mentored by [[VideoGame/AceCombat7SkiesUnknown Mihaly Shilage]] himself.
* AFatherToHisMen: As noted by the narrator, 13 prided himself not on his kill record, but on the fact that he never lost any of his wingmen in battle. [[spoiler:This ends during the destruction of Stonehenge.]]
* AntiVillain: He's show to be quite an honorable man, in spite of being the closest thing the game has to a BigBad. Over the course of the story he shows care for his wingmen, dislikes cowardice in battle (especially sabotage), pities the weaker enemies he shoots down, and derides the army's tactic of hiding AA guns on top of hospitals.
* EarlyBirdCameo: Shows up as one of the optional Aces in ''VideoGame/AceCombatZeroTheBelkanWar''
* WorthyOpponent: Longs to have one of this, and eventually comes to see Mobius One as this. The narrator speculates that [[spoiler: it brought 13 great joy when he and Mobius finally fought, even if it resulted in the former's death]] at the story's conclusion.
[[/folder]]

[[folder:Yellow 4]]

Yellow 13's most trusted and devoted wingman, determined to keep him safe both in the air and on the ground. She is the first Yellow Mobius One shoots down.
----

* WorfHadTheFlu: Her plane is in terrible shape when you shoot her down.

* HopeBringer: After [[spoiler:destroying Stonehenge and shooting down a Yellow Squadron member for the first time]] in Mission 12, Mobius One becomes a symbol of strength for ISAF's military. Erusian forces have [[TheDreaded the opposite reaction]]

* LoweredMonsterDifficulty: Over the course of the game, Yellow Squadron's veteran members are moved to other units as ISAF begins to regain territory, leading to less experienced pilots to join the squadron. In the first appearance, they cannot be shot down by any means. In their final appearance, they are essentially slightly more skilled standard pilots. Justified by that point, because [[spoiler:the Yellow squadron faced at Megalith are regular radical Erusean pilots who painted their planes in Yellow livery to honor their fallen comrades]].

* WeaponOfChoice: In nearly all promotional material, he is seen with an F-22A Raptor, which becomes available to the player in [[EleventhHourSuperpower the last two missions of the game]] on a normal playthrough. When he [[VideoGame/AceCombat5TheUnsungWar returns]] as player character in [[GaidenGame Operation Katina]], it's his only available plane for a first playthrough. His livery, complete with ISAF emblems, is available in nearly ever game after 04.

[[folder: Yellow 13]]

[[folder: Yellow 4]]

[[folder: Yellow Squadron]]

* HeroOfAnotherStory: He's involved in anti-Free Erusea ops with the IUN.

* LivingLegend: [[VideoGame/AceCombat04ShatteredSkies The one who spearheaded the liberation of the Usean continent from Erusea in 2005]]. Allied pilots have a hard time believing it's really him.

* OneManArmy: As tradition for Ace Combat player characters, but he especially embodies this trope due to the fact that, unlike many others, he does not fly with any wingmen for the entirety of the game. Though he is accompanied by [[spoiler:a "Mobius Squadron"]] in the final level, they do not behave any differently than regular ISAF pilots.
* OldSoldier: Has been on active duty for 10 years. Viper 2 even calls him an "old timer". Perhaps he's the reason Erusea hasn't gone anywhere near North Point in the main game.

* PreviousPlayerCharacterCameo: He's very same Mobius 1 you used to play as in ''Ace Combt 04''. Here, he takes to the skies again against another Free Erusea movement almost a decade after their first appearance.

* LoweredMonsterDifficulty: Over the course of the game, Yellow Squadron's veteran members are moved to other units as ISAF begins to regain territory, leading to less experienced pilots to join the squadron. In the first appearance, they cannot be shot down by any means. In their final appearance, they are essentially slightly more skilled standard pilots. Justified by that point, because [[spoiler:the Yeelow squadron faced at Megalith are regular radical Eruseans who painted their planes in Yellow livery to honor their fallen comrades]].

* AntiVillain: He's show to be quite an honorable man, in spite of being the closest thing the game has to a BigBad. Over the course of the story he shows care for his wingmen, pities the weaker enemies he shoots down, and derides the army's tactic of hiding AA guns on top of hospitals.

* LoweredMonsterDifficulty: Over the course of the game, Yellow Squadron's veteran members are moved to other units as ISAF begins to regain territory, leading to less experienced pilots to join the squadron. In the first appearance, they cannot be shot down by any means. In their final appearance, they are essentially slightly more skilled standard pilots. Justified by that point, because [[spoiler:Yellow 13 has already been shot down, presumably along with most of the squadron's veterans]].

* AcePilot: Mobius One's most formidable adversary, with sixty-four confirmed kills in his first appearance.

* ChildSoldier: Thirteen says he started training Four to be a fighter pilot when she was still a young girl.

One of ISAF's fighter pilots, and later their top ace.

* MissionControl: Is responsible for command and control during various ISAF operations, mainly the missions undertaken by Mobius One.

A militaristic, expansionist government and the main opposing force for the game.

* ChildSoldier: Thirteen says he started training Four to be a fighter pilot when she was still a young girl, [[UnfortunateImplications sooooooo...]]

* TheVoiceless: She doesn't have any lines in the whole game and she comes off as being generally a very quiet person.

* TheVoiceless: She doesn't have any lines in the whole game and she comes off as being generally a very quiet person.

* TheQuietOne: She's given maybe one line in the whole game (during the battle for Stonehenge), and she comes off as being generally a very quiet person, particularly in the Sky Kid pub when Four and Thirteen are silently chilling by themselves while the rest of the squadron are being loud, drunken, and jovial.

* SilkHidingSteel: Apparently carries around a perfumed handkerchief and drinks from what appears to be a porcelain teacup, all the while possessing [[YamatoNadeshiko a gentle and subdued demeanor.]] But let's not forget that she's also a career soldier and ace pilot who has probably killed her fair share of enemy pilots and soldiers in the name of her country.

* AcePilot: It comes with being the Yellow Squadron's second-in-command. She was apparently trained from a young age by 13 himself.

* ChildSoldier: Thirteen says he started training her to be a fighter pilot when she was still a young girl, sooooo...
* ClingyJealousGirl: With how protective she is of Thirteen, both in the air and on the ground, and for how long she's known him, it's no stretch to imagine that she's probably a bit possessive of him. Which of course frustrates [[PrecociousCrush the barkeep's daughter.]]
* TheQuietOne: She's given maybe one line in the whole game (during the battle for Stonehenge), and she comes off as being generally a very quiet person.
* TomboyWithAGirlyStreak: Career Soldier and Ace Pilot but also apparently carries around a perfumed handkerchief as well as possessing a rather subdued demeanor.

* TheVoiceless: At no point in the game is she given any lines, and she comes off as being a very quiet person.

Yellow 13's most trusted and devoted wingman, determined to keep him safe both in the air and on the ground.
