[-[[caption-width-right:326:Our heroes, rushing into battle.[[labelnote:Who?]]Clockwise from the left: [[MagicKnight Serena Corsair]]; [[WhiteMagicianGirl Nicole Neil]]; [[SquishyWizard Randy M. Green]] and his familiar, Nando; [[GratuitousNinja Ginjirou Ibushi]]; [[TheBigGuy Samuel Han]]; and the [[ABoyAndHisX Undead Hero]].[[/labelnote]]]]-]
A magically super-charged BeatEmUp for the Platform/SegaSaturn by Creator/{{Treasure}}. A group of adventurers find a powerful magic sword, but unfortunately, TheEmpire has been looking for that very weapon. A red-armored girl bursts into their room just as Imperial soldiers start streaming in. They fight their way out of the town to a nearby graveyard, only to be confronted by [[SchizoTech a robot]]. In the middle of a difficult fight, suddenly a massive armored skeleton, the sword's original owner, arises from his grave to claim it.

''Guardian Heroes'' is, in a word, frantic. Lots of different characters, both allies and enemies, with nearly all of them available in the game's Versus Mode, with full six-player support. The gameplay is mostly two-dimensional, with the action spread across three planes, giving plenty of space for some massively large magic attacks (Treasure had experimented with this with ''Yu Yu Hakusho: Makyou Toitsusen'' for the [[Platform/SegaGenesis Sega Mega Drive]]). Of the heroes, each has a wide variety of attacks, plus magic spells which as their levels increase, gets bigger and more destructive. Through the game, you're followed by the aforementioned Undead Hero, who can be given different commands such as protecting you, staying his sword, attacking of his own initiative, or just going berserk and burning everything before obliterating whatever's left with a SphereOfDestruction. Depending on your choices during the course of the game, you could liberate the kingdom, storm the gates of Hell, storm the gates of ''Heaven'', or face down a robotic army led by Golden Silver, the final boss of ''VideoGame/GunstarHeroes''.

A sequel, ''Advance Guardian Heroes'' was released, [[SuperTitle64Advance as the name suggests]], on the Platform/GameBoyAdvance, which ties the game even closer with ''Gunstar Heroes''. In this game, the villains from the previous game have returned centuries later, ready to try again to take over the world. A young soldier allows himself to be possessed by the spirit that inhabited the Undead Hero to fight them again.

After roughly 15 years, Treasure announced in May 2011 that they would be re-releasing the original ''Guardian Heroes'' on Platform/{{Xbox 360}} via [[Platform/XboxLive Xbox Live Arcade]], as ''Guardian Heroes HD''. As the name implies, the game was updated with HD graphics, new artwork, new A.I., re-designed gameplay mechanics, a re-translated script, new voice-acting, online co-op, and a new 12-player online mode, although the option to play it like the original Saturn version is also available. It arrived on October 12, 2011, and at the low price of $4.99.

For games with similar gameplay to ''Guardian Heroes'', ''VideoGame/PanzerBandit'', ''VideoGame/CodeOfPrincess'' (a SpiritualSuccessor for the Platform/Nintendo3DS, Platform/NintendoSwitch, and Steam), and ''VideoGame/PhantomBreaker''[='=]s retro-styled brawler spin-off, ''Phantom Breaker: Battle Grounds''.

----
!!This game contains examples of:
* ActionGirl: Serena, a knight [[spoiler:and a [[RoyalsWhoActuallyDoSomething princess]]]] who's not only good with a sword and shield, but an adapt spellcaster with array of magic attacks at her disposal.
* AIIsACrapshoot: [[VideoGame/GunstarHeroes Golden]] [[TheCameo Silver]] in ''Guardian Heroes''.
* AncientConspiracy: [[spoiler:Heaven]] in ''Advance Guardian Heroes'', working for eons in order to create the Ultimate Warrior.
* AmericanKirbyIsHardcore: The American cover replaces the original anime-esque artwork with a fantasy novel-esque illustration depicting Han fighting the Undead Hero (even though he's a good guy). The European cover kept the original art, but turned the cover into a complete sausagefest by having the heroines Serena and Nicole replaced with Zur the magician and Macho the beefcake (who aren't even main characters).
* AndYourRewardIsClothes: A meta-example in the Xbox 360 version; scoring 360 points in the Arcade Mode nets you the Undead Hero's helmet. Unfortunately, the rest of the outfit (and other ''Guardian Heroes''-themed outfits) has to be bought through the Avatar Store.
* {{BFS}}: They only reason the CoolSword may not look ''too'' big is because the guys carrying it are huge, too.
* BlindIdiotTranslation: Most of the script for ''Advance Guardian Heroes'' is like this, and in some spots (like the intro) it becomes a full-on TranslationTrainWreck.
* {{Bookends}}: ''Advance Guardian Heroes'' starts and ends with a CounterAttack.
* CoOpMultiplayer: The Story Mode of the first game allows two players to play through the adventure although the continues are shared among players.
* CompetitiveMultiplayer: The first game's Versus Mode lets up to six players (or twelve in the HD version) to duke it out with any character they've unlocked through the Story Mode as a fighting game.
* CounterAttack: In the original version of ''Guardian Heroes'', if a player is being attacked from behind, pressing the Strong Attack will cause the player to counter from both sides. In the Remix Mode of the HD version, if players have at least 60 MP, they can blow away their attackers and other near-by enemies by pressing the Strong Attack while holding the Guard button. In ''Advance Guardian Heroes'', blocking at the right time to stun and counter enemies is an important combat mechanic. Its climax even revolves around it, with the hero reflecting a giant fireball the instant [[labelnote:*]]Under 00:00:11[[/labelnote]] before it hits Earth.
* CrutchCharacter: The original ''Guardian Heroes'' characters in the sequel, in an unusual example of this trope. Defeating one of them in battle allows you to borrow their power, which gives you massive stat boosts. If you still aren't leveling up your stats normally, though, it'll come back to bite you in the ass later, as you frequently lose those powers throughout the game (usually when you fight another one of the original party, as the party members you've already beaten come back out and fight against you again). And at the end of the game, the final boss permanently removes these powers one by one.
** Han using the Undead Hero’s sword in the beginning. It massively raises his stats, but he loses the boost quickly when the Hero takes it back. One route has you fighting another Undead Warrior with a similar sword, and if Han is present in that fight, the Warrior will bequeath that sword to him for a similar boost.
%%* CompetitiveBalance
%%* DarkIsNotEvil: Depending on what path you take.
* DieChairDie: You can wreck inanimate objects like chairs and barrels, but doing so will lower your karma.
* DealWithTheDevil: If you die in the sequel, a mysterious figure appears and offers you immortality in exchange for your soul. Agree, and you turn invincible for a period of time depending on the difficulty mode. Once the time runs out (which doesn't happen in Super Easy), you're killed. Using it at any point will automatically net you the bad ending, though, and even if you manage to beat a stage, you won't be able to level up.
* GameplayAllyImmortality: The Undead Hero in the first game's Story Mode can get hit by enemies, but he can't die since he's already dead. According the developers, the reason behind this gameplay design decision was to balance the difficulty as players could end up fighting against a huge number of enemies that would be impossible to deal with alone. Randy's familiar Nando is also immortal when players play as him in Story Mode.
* GoneHorriblyRight: [[spoiler:Heaven's]] plan to make Ultimate Warriors worked a little too well, what with [[spoiler:making the Undead Warrior a vessel strong enough to defeat Demon]] in ''Advance Guardian Heroes''.
* GoshDangItToHeck: Zur in the re-translated script for the remake is all about this, with hilarious results.
* HeadSwap: Some of the enemies are head-swaps of other characters (including the heroes), but they do provide a good explanation for some of them.
** Han is the former leader of the blue knights and the new leader, Gash Deadeye, used to be his second-in-command.
** Katrina, the new leader of the red knights, was Serena's old rival when Serena was the leader.
** Macho and Sambo, the leaders of the Godats thieves, are head-swaps of each other (except that Macho fights shirtless as well).
** Manon F. Brown (Randy's mentor) trained under the same mentor as Kanon G. Grey.
** The Undead Rogue is a head-swap of the Undead Hero except hhas an arm missing.
* HeelFaceTurn: [[spoiler:Valgar in the original game, depending on which route the player takes.]]
* HeroicSacrifice: In ''Advance'', if the player loses to the final boss the first time, Dylan will sacrifice himself to refill the player's health.
* HitodamaLight: Hitodama appear in a single stage where they don't attack, can't be hit, but they also possess killed enemies and reanimate them.
* HoistbyHisOwnPetard: [[spoiler:Heaven, and by extension, Demon]] in ''Advance Guardian Heroes''. First was their plan to make Ultimate Warriors as servants — [[spoiler:[[PhlebotinumRebel they never expected it to be strong enough to defeat them]]]]. Second, when the final boss tries [[EarthShatteringKaboom destroying the Earth with a fireball]] — [[PlayingTennisWithTheBoss it gets reflected]] [[NiceJobFixingItVillain back at him]].
* HouseRules: The HD version gives players the option to create their own set of game rules and settings for a match. These options are but limited to: using the original or redesigned gameplay mechanics, minimum and maximum level cap, adjusting the damage scale from x0.5 to x10, altering a character's moveset, allowing or restricting characters from play, whether or not elemental properties should apply in matches, and much more.
* JokeCharacter: Both ''Guardian Heroes'' and ''Advance Guardian Heroes'' lets you play as inneffectual characters such as villagers, wolves, and the tiny goblins. They have appropriately pathetic attacks and stats.
* KamehameHadoken: Many of the more powerful spells in the game.
* KarmaMeter: The game features one that decides whether or not you'll get the "light" or "dark" version of certain endings. Beating up bad guys, allowing fleeing enemies to escape, and not harming the civilians can increase your karma, while attacking bystanders, fleeing enemies, continuously attacking a defeated enemy, and destroying inanimate objects (e.g. a barrel of produce, crates, a chandelier) will lower it.
* KickThemWhileTheyAreDown: It's possible to continue attacking defeated enemies in the first game, and in the original Saturn version or the Original Mode in the XBLA version, gain EXP from it, but doing so will lower your karma.
* KillerRabbit: Randy's pet bunny, Nando. He can ''set himself on fire'' and hurl himself at enemies.
* LaResistance: They need all the help they can get.
* LinearWarriorsQuadraticWizards: Randy's moveset can completely shut down almost every enemy in the game, in ''groups''. Characters like Han are designed for single-opponent bashing.
* LuckStat: Not only is Luck used instead of defense (the higher your luck, the less damage enemies will do), Nicole's randomized magic types are dependent on Luck; the higher the Luck, the bigger they will be. Not always a good thing.
** Not only does it help reduce the damage taken, it can also give you random bursts of extra damage. It also increases the amount of EXP you earn.
* MadeInCountryX: In the HD version, the Royal Mech will sometimes say this as its victory quote: "Why does it say 'Made in Taiwan' on my butt. *sigh*"
* MultipleEndings: Thanks to the branching paths the first game offers, it has no less than five possible endings, with a few of that having a "light" or "dark' version depending on your karma meter.
* {{Ninja}}: Ginjirou. He utilizes lightning-based ninjitsu attacks and agile maneuvers.
* NintendoHard: ''Advance Guardian Heroes''. You get only one life, unless you make a DealWithTheDevil, and even in that case, you can only use it to preview some more of the stage for your next attempt before you die regardless, and using it even once leads to a BadEnding. Thankfully, the game allows you to start over from your last checkpoint... with however much health you had when you reached said checkpoint.
** The game has four difficulty levels: Easy, Normal, Hard, and [[HarderThanHard Super Hard]]. Super Hard truly lives up to its name. The enemies not only become more powerful, but will be allowed to make use of previously player-exclusive mechanics such as counters and the Anger Mode to interrupt your combos.
* NonCombatEXP: In the original Saturn version of the first game or the Original Mode in the HD version, using your character's spells, including the defensive ones, will give your character EXP.
* NonPlayerCharacter: Every single character in Story Mode (including neutral villagers) can be used in Versus Mode except for Princess Lucia, the King (Valgar and Lucia's father) and Manon F. Brown.
* NonStandardGameOver:
** When you run out of HP in ''Advance Guardian Heroes'', the BigBad will offer you an "invincible body": all you need to do is [[DealWithTheDevil sell your soul]]. Refuse, and the game ends right away. Accept, and you will enter "Devil Mode", with your body enhanced so that you are effectively immortal. After a few minutes, however, the Big Bad will collect on his part of the bargain and kill you right away, ending the game and forcing you to start over back at the point where you ran out of HP originally. You also cannot beat the game in Devil Mode: reaching the end in this state will result in an immediate Game Over.
** Fail to reflect the final boss' DesperationAttack in ''Advance Guardian Heroes'' and watch the [[EarthShatteringKaboom Earth explode]].
* NotSoHarmlessVillain: Zur, after he steals Valgar's magic and becomes Super Zur.
* OurZombiesAreDifferent: The Undead Warrior, who fights on your side throughout the game.
* PaletteSwap: Most of the enemies in Story Mode. Specifically, Valgar adopts a white armor when he joins the Sky Spirits in one of the possible routes. In Versus Mode, everyone gets at least six (or twelve, in HD version) possible color schemes. When Mid (the giant monster plant in Stage 03) is defeated, his true form is revealed to be a palette swap of Randy's pet Nando.
* PhlebotinumRebel: It turns out that [[spoiler:the player character]] is this in ''Advance Guardian Heroes''.
* PlayingTennisWithTheBoss: The sequel is all about this. [[spoiler:It's also a requirement for the final boss.]]
* PsychoForHire: Zur, so very, very much.
* RoadCone, ThirdOptionAdaptation: The story in the sequel assumes an ending to the first adventure that could not have taken place in the actual game — but still significantly resembles ''one'' of the original endings, except for how it turned out.
* ScratchDamage: Blocking against magic attacks in the original game will chip away your character's HP. In the HD version, there's an option for custom Versus Mode rules to enable chip damage for physical attacks as well.
* SchizoTech: You got your robots in my MedievalEuropeanFantasy! You got your Medieval-European Fantasy in my robots!
* ShoutOut: In the HD re-release of the game, Zur puts his own spin on the famous Platform/SegaGenesis [[TakeThat commercial]] before fighting you in Stage 25.
* ShoutOutThemeNaming: Edward and Randy are named after Edward Randy, the main character from the Creator/DataEast arcade platformer ''The Cliffhanger''.
* SpellMyNameWithAnS:
** In the GBA sequel, Serena became "Cerena."
** The ''HD'' version featured a different translation, changing many character names. Samuel Han, for example, becomes ''Samwell'' Han, and Kanon G. Grey becomes Kanon ''The'' Grey.
* SphereOfDestruction: As with the KamehameHadoken, many characters have a spell looking like a magical energy grenade for the smaller ones, to what the game itself describes as a "[[ExactlyWhatItSaysOnTheTin full-screen explosion]]".
* SissyVillain: Zur.
* TakingYouWithMe: When Kanon's flying fortress in the sequel starts to crash with the player and Dylan inside it, Dylan invokes this trope. [[SubvertedTrope He then waits for you to leave and runs like hell.]]
* ThemeNaming:
** The three main heroes in the GBA version are named after the elemental powers they use: Enn comes from ''En'' or fire, Hyu comes from ''Hyō'' or ice, and Ray comes from ''Rai'' or lightning.
** The initials of the other main heroes in ''Advance Guardian Heroes'' (including those from the previous game) form the game's title: '''A'''dmilla, '''D'''ylan, '''Va'''lgar, '''N'''icole, '''C'''erena, '''E'''do, '''G'''injiro and '''H'''an (Advance GH). Granted, Cerena was originally named "[[SpellMyNameWithAnS Serena]]" and Edo is actually Randy's pet possessing Randy's body, so they cheated a bit to make this work.
* UpdatedRerelease: The HD version features (obviously) optional HD graphics, redrawn character artwork, new A.I., a re-translated script, new voice-overs, new sound effects, and online multi-player with an expanded 12-player Versus Mode. There's also the "Remix" mode of the game that changes quite a lot of how the game is played (you now have three attack buttons instead of two, normal attacks can be canceled with stronger attacks, MP is capped to 100, air-dashing is possible, etc.), although the ability to play the game with the original mechanics are still available in Original mode.
* WakeupCallBoss: Hope you make the right choice and don't end up battling Kanon after the first 3-4 stages, or you'll regret it. ''Hard''.
