History VideoGame / PokemonFoolsGold

** Some Pokémon, unlike in the officials games, require friendship to be completely maxed out in order for it to evolve.

* UndergroundMonkey: The entire point of this game is to give all the {{Mons}} up to Hoenn (and a few extras) alternate forms a la Alolan or Galarian forms. There's even alternate forms ''of the new forms'' in Kanto and Sevii (though only three Seviian forms exist in the form of the final stages of the Kanto starters, more are planned to be added in future updates).

The story and plot remain largely unchanged from ''Crystal'', but the game's main draw is that every Pokémon up to [[VideoGame/PokemonRubyAndSapphire Generation III]] (along with cross-generation evolutions, including regional evolutions introduced in ''VideoGame/PokemonSwordAndShield'') have been given strange new regional forms, known collectively as "Fool's Forms". The game also has a few features from later generations, specifically a number of moves and the physical-special split. There's also a number of new areas to explore and new people to meet...

** Little to no information is provided in-game on how to encounter the Regi Golems, most players will find them by looking up walkthroughs..

** Much like Dhelmise, the newly added Seviian Qwilfish line doesn't have any info in-game on where to obtain it, or even that it exists. In a strange way, this is a zig-zagged example as not even the hack's designated online wiki/guidebook provides any help, as the only thing written under its location is "It's a Secret!"

* DiscOneNuke: If you used the password that lets you choose from the Kanto starters at the beginning, Squirtle is absolutely this. It learns Dragon Rage at level 10, a move that always does a fixed 40 damage to its target, and considering nearly all early game Pokémon have under 40 HP, you can easily one-shot most trainers up to Azalea Town who are in your way.

** After getting Waterfall, you can battle the developers of the game. Beating then will net you a [[VideoGame/{{Earthbound}} pencil eraser]], which grants access to a cave where one can find [[spoiler:Missingno, the OG Glitch Entity in ''Pokémon''. Like Aerodactyl, it's ???-type and has a glitched-out Pokédex entry. Worth noting is that its HP, Defense, and Special Defense stats are all base ''zero'' (though the stats themselves never reach zero, they're still [[GlassCannon mighty low]])]].

** Upon beating the developers in Daffodil Creek, you are given a [[VideoGame/{{Earthbound}} pencil eraser]] that removes a pencil-shaped statue blocking a cave.

** The Legendary Birds are outright described as [[VideoGame/PokemonSunAndMoon Ultra Beasts]] and are part ??? type. All three of them are terrifying {{Eldritch Abomination}}s from another universe, with Articuno being the only one who remains vaguely bird-like.

** [[spoiler:Deliberately invoked with Eris in their final fight, as all of their mons are above level 100. It turns out that they did indeed cheat to make them stronger, something they admits after you beat him.]]

** [[spoiler:Eris's trainer sprite in his final fight is surrounded by a glitchy aura, hinting at the fact that he cheated to make his Pokémon above level 100.]]

** Aerodactyl is a terrifying GlitchEntity husk of its former self, also being pure ??? type. Its Pokedex page is (deliberately) glitched to hell and back as well.

* ApocalypseHow: According to the Pokedex entry, it is theorized that when herds of Kantonian Togekiss gather it signifies the end of the world.

** The method of encountering Mew harkens back to the early days of the fandom; that is, [[spoiler: the classic "Mew under the Vermilion truck" rumor. By interacting with said truck with Mewtwo in your party, you'll be able to encounter the Mythical Pokémon]].

* AwfulTruth: [[BleakLevel Tumbleweed Town]] reveals the truth behind the nurses at the Pokémon Centers: [[spoiler: They're created from people who step into a special machine which forcefully transforms their bodies into Nurse Joys. Additionally, many of these transformations go haywire, resulting in [[ImMelting melting]] {{Humanoid Abomination}}s who speak in [[OminousVisualGlitch glitchy text]].]]
* BeyondTheImpossible: [[spoiler: All of Eris's Pokémon are above level 100 in his final match, with his SignatureMon Sirfetch'd being at level ''120''. After you beat him, he later admits he cheated to make them over level 100.]]
* BleakLevel: The newly-added Tumbleweed Town is an abandoned, barren town in the middle of the desert, complete with the [[SarcasmMode lovely]] original Lavender Town theme playing in the background. It's also home to an abandoned Pokémon Center [[spoiler: filled with horrific HumanoidAbomination Nurse Joys]].

** Tumbleweed Town's Pokémon Center reveals an AwfulTruth about the Johto region: [[spoiler: Its Nurse Joys are created via forcefully [[ForcedTransformation transforming people and their bodies into that of the Nurses we know and love]]. The Abandoned Pokémon Center is home to tons of these failed Nurse Joys, who are practically ''melting'' and speak in garbled, [[OminousVisualGlitch glitchy]] text. Even the relatively "normal" one on the top floor who heals your Pokémon still speaks in a slurred, glitchy manner.]]

* BraggingRightsReward: [[spoiler: Arceus retains its amazing stats from vanilla and, while it's [[NonElemental ???-type]], it resists ''every type in the game''.[[note]]The way the developers pulled this off is by making a completely separate type for Arceus that resists every other type but is still labelled as ???. A similar trick was pulled off for Shedinja, who is a OnePointWonder but is immune to a variety of types.[[/note]] However, by the time you catch it, there won't be much left for you to sic it on, if anything.]]

** [[spoiler: Deliberately invoked with Eris in his final fight, as all of his mons are above level 100. It turns out that he did indeed cheat to make them stronger, something he admits after you beat him.]]

* DarkerAndEdgier: Though the story remains largely unchanged from ''Crystal'', the designs of the Pokémon are a bit darker in general, with a decent amount of BodyHorror and AdaptationalAbomination designs. There's also Tumbleweed Town, a completely abandoned GhostTown [[spoiler: with a Pokémon Center that hides a terrifying secret]]. Additionally, there's a few more mature jokes here and there, like how the Miltank farmers can't sell diseased meat because of the [[PrecisionFStrike damn]] FDA.
** The Sevii islands campaign becomes a bit darker with its use of swears and mature jokes. Special mention goes to the seventh shrine, where [[spoiler: Eris goes on a [[ClusterFBomb swear-filled tirade]] about how it's unfair that you keep beating him despite putting a lot of effort into building his team]].

* DiscOneNuke: If you used the password that let's you choose from the Kanto starters at the beginning, Squirtle is absolutely this. It learns Dragon Rage at level 10, a move that always does a fixed 40 damage to its target, and considering nearly all early game pokemon have under 40 HP, you can easily one-shot most trainers up to Azalea Town who are in your way.

* FluffyCloudHeaven: [[spoiler: Resting in the Lakeside Inn will send you to a dream world that highly resembles this. It's home to one of Sevii's seven shinies, in this case Chimecho. Additionally, Pokémon themed around angels and devils, specifically Chingling, Snorunt, and Taillow, can be found in the grass there.]]

** Aerodactyl is a [[NonElemental ???-type]] glitchy abomination that's based off of Missingno's Aerodactyl fossil form, complete with an ''extremely'' glitched-out Pokedex entry.

** [[spoiler: The Nurse Joys are implied to be this, as they speak in glitched-out text and even use the aforementioned Aerodactyl.]]
** After getting Waterfall, you can battle the developers of the game. Beating then will net you a [[VideoGame/{{Earthbound}} pencil eraser]], which grants access to a cave where one can find [[spoiler: Missingno, the OG Glitch Entity in ''Pokémon''. Like Aerodactyl, it's ???-type and has a glitched-out Pokedex entry. Worth noting is that its HP, Defense, and Special Defense stats are all base ''zero'' (though the stats themselves never reach zero, they're still [[GlassCannon mighty low]])]].
** [[spoiler: Eris's trainer sprite in his final fight is surrounded by a glitchy aura, hinting at the fact that he cheated to make his Pokémon above level 100.]]

* InnBetweenTheWorlds: As a CallBack to the Harbor Inn in ''VideoGame/PokemonDiamondAndPearl'', Four Island has a mysterious, abandoned inn known as the Lakeside Inn. [[spoiler: Repeatedly entering and exiting the inn will have an old man escort you to the inn's bed for a nap, claiming that you have a reservation. At first, it seems like you're heading into a nightmare world similar to that of the Harbor Inn's. However, you wake up in a FluffyCloudHeaven where a shiny [[OurAngelsAreDifferent Chimecho]] awaits, along with rare Pokémon like Chingling and Snorunt.]]

* TheMaze: The Lost Cave is a labyrinth that seals you in until you find the exit, with near-identical rooms making it difficult to navigate. [[spoiler: At the end of the cave lies a shiny [[PlagueDoctor Altaria]], who claims to be your end before battling you.]]

** [[spoiler: Arceus's Fool's Form has design elements borrowed from its beta/placeholder design found in the leaked ''VideoGame/PokemonDiamondAndPearl'' prototype, as seen [[https://tinyurl.com/yjbwc7nw here]].]]

* TrueFinalBoss: [[spoiler: After beating Eris, you battle the Shrine of Ascension's Totem Pokémon, who is none other than Arceus. It resists every type and packs powerful moves, so be prepared.]]
* OurAngelsAreDifferent: The Chimecho line is basically a G-Rated version of biblical angels. Chingling has a single, prominent eye and the wings of classical angels, while Chimecho has a ring-shaped head with several eyes and six wings, two of them being feathered wings on its head. Despite their [[AngelicAbomination unsettling origins]], both are perfectly benevolent and actually pretty adorable. [[spoiler: As a bonus, the shiny Chimecho you meet in the FluffyCloudHeaven outright says "BE NOT AFRAID" before you battle it.]]

* SecretCharacter: Aside from [[spoiler: Arceus]] (and technically [[spoiler: Missingno]]), there is one Pokémon in the game that isn't from Gens I-III or related to them via evolution, and can only be found via a password found in a ''very'' obscure location. That Pokémon is [[spoiler: Dhelmise, now a Dragon-type]], whose password is [[spoiler: found on the ''crash screen'', of all places]]. Once entered, it can be found on [[spoiler: Route 52]].

** [[spoiler: The cloudy dream world you enter in Four Island's Lakeside Inn is highly reminiscent of the Coin Heavens in the ''Franchise/SuperMarioBros'' series, with the background music being similar to the Coin Heaven theme from ''VideoGame/SuperMarioBros3''.]]
* SoreLoser: Eris doesn't take losing very gracefully since they pride themselves on their high-leveled, perfect stat Pokemon team. At first they just shake it off and see you off to explore the Sevii Islands, but after every progressive loss they get more and more frustrated to the point that they basically rant to you [[spoiler: at the top of the seventh shrine]].

* VisualPun: Fool's Scyther is a fire-type ant, a ''fire ant''.

* DarkIsNotEvil: Fool's Ho-Oh trades its Fire typing for Dark and has a black-and-purple color scheme lit up only by yellow stars. However, it's just as benevolent as its regular counterpart, and is treated as TheSacredDarkness.

** Tumbleweed Town's Pokémon Center reveals an AwfulTruth about the Johto region: [[spoiler: Its Nurse Joys are created via forcefully [[BalefulPolymorph transforming people and their bodies into that of the Nurses we know and love]]. The Abandoned Pokémon Center is home to tons of these failed Nurse Joys, who are practically ''melting'' and speak in garbled, [[OminousVisualGlitch glitchy]] text. Even the relatively "normal" one on the top floor who heals your Pokémon still speaks in a slurred, glitchy manner.]]

* SoreLoser: Eris doesn't take losing very gracefully since they pride themselves on their high-leveled, perfect stat Pokemon team. At first they just shake it off and see you off to explore the Sevii Islands, but after every progressive loss they get more and more frustrated to the point that they basically rant to you [[Spoiler: at the top of the seventh shrine]].
