''The Guardian Legend'' (known as ''Guardic Gaiden'' in Japan) was a hybrid ActionGame and [[ShootEmUps Shoot Em Up]] created by {{Compile}} for the NintendoEntertainmentSystem. Released around 1988, it's likely forgotten by all but the most hardcore of gamers, but this game did a great job of blending the two genres.

The game is about a [[RobotGirl female robot]], codenamed "the Guardian", who is commissioned with stopping an alien-infested planet called Naju from [[ColonyDrop crashing into Earth]] and killing everyone. To do this, she must set off ten strategically-placed explosives within the corridors (by transforming into a spaceship and flying through them) and defeat the bosses within.

!!Provides examples of:

* ActionGirl: The game's protagonist.
* ApocalypticLog: The corridors are peppered with notes from a deceased native of the place that tells you how to unlock some of the trickier doors.
* ArtificialHuman: The Guardian herself.
* BeamSpam: Many of the corridor areas have enemies that shoot a hail of lasers (especially at the end, when the [[DemonicSpiders laser-shooting ships have DEADLY beams]]). Also Eyegore, a [[ExtraEyes multi-eyed]] skull boss loves this trope too.
* BlindIdiotTranslation: For example, in the manual, "The Guardian is a sophisticated aerobot transformer".
* BossRoom: When you walk into a room and hear a warning klaxon and see [[GhostButler indestructible pyramids closing around you]], be prepared to fight!
** Or not. The pyramids close slowly enough that you can run out before the boss appears if you're quick!
* BossRush: "Corridor 21", and "TGL mode", which puts you through only the flying stages.
* BossWarningSiren: The normal music for the area turns off and a low and slow "bwoom" sound plays to warn of an oncoming boss. In the exploratory areas, this is accompanied by green pyramids closing off passages to other areas; it's possible to escape before the boss arrives. In ship areas, you have no choice and must confront the boss.
* BreastPlate: Perhaps justified, as the Guardian's main defense is a personal nigh-invisible [[DeflectorShields force field]].
* CoolShip: A strange variation, as the main character ''[[SpaceshipGirl is]]'' [[SpaceshipGirl the cool ship]] (at least, she can [[TransformingMecha transform into it]]).
* CoresAndTurretsBoss: The very first boss of the game, as well as [[ExtraEyes two of the organic corridor bosses]].
* CoversAlwaysLie: The North American boxart for the game looks like [[http://upload.wikimedia.org/wikipedia/en/6/6a/TGL_Box.jpg this]], and has pretty much nothing to do with the game.
* DeadManWriting: When you first enter the labyrinth.
* [[DegradedBoss Degraded Mini Boss]]: One of the minibosses in the labyrinth stages [[BossinMookClothing appears as a regular enemy later]], while still retaining its high health and brutal collision damage...
* DestructibleProjectiles: All of the enemy bullets can be destroyed, and you can get random drops from them.
* DifficultButAwesome: According to the UWW of this game, LordKat apparently discovered the ripple weapon being incredibly useful against the later bosses once fully upgraded. It's all a matter of using it correctly.
* EarthShatteringKaboom: The goal of the game is to prevent this from happening.
** ... by making it happen to ''someone else''.
* EveryTenThousandPoints: The game rewards high scores by increasing you health meter every so many points, starting at 30,000 points. At the same time, the game will '''crash''' if you reach the score's {{cap}}.
* EveryoneCallsHimBarkeep: The Guardian's name [[NoNameGiven is never revealed in the game or the English instruction manual]]. According to the [[CanonName original Japanese manual]], she is called "Miria" (full name: "Strongest Warrior System D.P., pet name Miria"). {{Fanon}} refers to the Guardian as "Alyssa".
* EverythingsSquishierWithCephalopods: Zibzub, a red squid boss.
* EvolvingAttack: Both your main gun and your special weapons.
* ExplosiveBreeder: One of the enemies in the labyrinth areas is a [[DemonicSpider blue spider]] that if left unkilled, turns orange, then red, then it splits into seven identical copies of itself. These individual copies can split even more, making things a little... complicated.
* ExactlyWhatItSaysOnTheTin: The [[SmartBomb Enemy Eraser]].
* ExtraEyes: [[EyeScream Grim]][[ThatOneBoss grin]]. Eyegore too, but he ain't nearly half as tough as Grimgrin...
* EyeBeams: [[ThatOneBoss Optomon]] likes this one a lot.
* EyeScream: Inevitable, given the number of eyeball-related enemies. [=GrimGrin=] even TurnsRed and turns up the number of objects it spits at you once you've punched out its main eyeball.
* FighterLaunchingSequence: The Guardian launches to and returns from the flying levels in this manner.
* FlipScreenScrolling: The labyrinth areas.
* GameMod: The "Secret Edition" rom hack, which takes the original's NintendoHard difficulty UpToEleven by, among other things, [[TookALevelInBadass giving Teramute a major upgrade]], making him a new ThatOneBoss.
* GiantEnemyCrab: Crawdaddy, the boss of Corridor 2 (actually more of a lobster). One of the minibosses in the labyrinth areas IS a large crab that [[MakingASplash sprays bubbles about]], though.
* GiantSpaceFleaFromNowhere: It (a.k.a The Final Guardian), the FinalBoss, who appears out of nowhere after the BossRush, just when you think you're home free. (In a bout of FridgeLogic, it shouldn't matter that much if you beat it or not, since it only appears ''after'' you've succeeded in your mission to blow up the planet.)
* IfYouCanReadThis: All of the messages left to you by the last (good alien) survivor of NAJU comes in the form of giant monitors on the floor.
* InsurmountableWaistHighFence - Those indestructible pyramids blocking your passage, until you gain enough speed upgrades to outrun the miniboss room ones or slip through the tiny gaps between the regular ones.
* IntangibleMan: You can easily walk though vertical 1-thin walls (apparently depends on a couple of factors, like emulator being used, etc) with enough speed upgrades.
* InstantAwesomeJustAddDragons: All monsters and bosses are strange alien creatures, except for one dragon boss.
* InvincibleMinorMinion: Mostly averted. While a few of the enemies seem nigh-impossible to defeat, they usually just have a ton of HitPoints. Of course, the [[SmartBomb Enemy Eraser]] decimates them with ease.
* ItemFarming: You often have to farm enemies to get health and energy item drops before going into a corridor or optional boss fight.
* HitboxDissonance: The game is extremely lenient when it comes to what parts of your sprite take damage, and what parts of enemy sprites give damage (especially the bosses). The fact that the game is still NintendoHard in spite of this says something.
* KillItWithFire: The Fireball weapon. [[InfinityPlusOneSword Especially at max level, when it can cause massive damage AND destroy enemy attacks]].
* LaserBlade: The Saber Laser and [[DualWielding Cutter Laser]] weapons.
** They are also usually the easiest way to take down many of the otherwise challenging bosses. Lightsabers are just better, it seems.
* LastChanceHitPoint: You will not die when your shields drop to zero. The next hit will destroy you, though.
* LevelGrinding: Killing enemies over and over will increase you score and eventually award you with one extra point of health. This ceases to be benefitial when at one million points you start needing another million for one health point.
* TheLostWoods: The forest labyrinth area as well as the forest corridors.
* MacrossMissileMassacre: The Bombardier boss can fire no less than 12 or so missiles at you in one go. Its missiles, however, are very weak, [[BreatherBoss especially when you fight it the second time round]].
* MechanicalLifeforms: Most of the enemies infesting Naju.
* MercyInvincibility: Minimal, providing less than a second of protection, and only against small enemy collisions. Large lasers or enemy attacks do so much damage - sustained contact drains your shield almost instantly.
* MookMaker: LOTS of them...
* MoreDakka: The Guardian's default gun relies on this principle. The more chips she's carrying, the more bullets-per-second she can shoot. The enemies also get this trope - in some of the later corridors, you'll find yourself facing an inspiringly absurd number of bullets and missiles and flying enemies and EVERYTHING ELSE.
* OrganicTechnology: Those enemies that aren't MechanicalLifeforms.
* OurDragonsAreDifferent: Teramute, a dragon boss that sprays fireballs. [[BreatherBoss It's very easy, unfortunately]].
* PasswordSave: Deemed on of the flaws of the game, the password system is overly complicated and long.
* PaletteSwap: It's a NES game, so of course.
* PinataEnemy: In the overworld section, the enemies that resemble an ice crystal will drop a heart almost every time.
* RandomDrop: One of the most important mechanics of the game.
* RareCandy: The miniature Blue and Red Landers increase your maximum health and chip capacity, respectively.
* RecurringTraveler: The Big Blue Lander shopkeeper.
* PowersOfTwoMinusOne: The "count" display will only go up to 255.
** Which is strange, as other counters go up to 9,999,990 (score) and 9,999 (chips).
* SequelFirst: More precisely, GaidenGame first. The original ''Guardic'' was a Japanese-only MSX game.
* ShootOutTheLock: You have to do this for Corridor [[spoiler: 1 by shooting out the gate]], Corridor [[spoiler: 5 by shooting out the corridor display panel]], and Corridor [[spoiler: 6 by using a special weapon on the gate.]]
* SmartBomb: The Enemy Eraser, which destroys all small enemies and projectiles on the screen. They become vital for surviving later parts of the game.
* SoleSurvivor: Aside from the Red and Blue Landers, NAJU was overrun by hostile aliens, and said survivor died sometime before your character arrives.
* SpaceshipGirl: Your main character is a female android who can [[TransformingMecha transform into a spaceship]].
* TeleportSpam: Bombardier and Teramute love to do this, as do some of the mini-bosses.
* TurnsRed: Clawbot, Grimgrin (who also ShowsDamage), and the FinalBoss (who ''literally'' turns red).
* UndergroundMonkey: LOTS of enemies, including some bosses.
* UnderTheSea: The Water area (although interestingly, some of the Water bosses are recycled for ''other'' areas).
* WaitingPuzzle: How the seal for door three is opened, and provides the page quote for that trope.
* AWinnerIsYou: "You are the greatest player." is displayed at the end, along with your score and some extra art.
* WombLevel: The Organic area corridors.
