History YMMV / PokemonColosseum

* CounterpartComparison: Rui gets compared to Misty from the main series because they're both redheaded girls with similar pigtails.

** The fact that shiny Shadow Pokémon probably won’t remain shiny once purified because they receive a second RNG roll when purified. It was actually likely a glitch or oversight, as it was fixed in the sequel and shiny locks are in full effect there.

* TheyChangedItNowItSucks: ‘’XD’’ gets two main complaints: the difficulty level is slightly less than ‘’Colosseum’’ and rather than Wes coming back or another older protagonist taking his place, they went with another child protagonist.

* [[https://www.youtube.com/watch?v=_QR-cfd6hCs Pyrite Town]], a catchy, jazzy number painting the vivid picture of [[ViceCity the smoky, sneaky town of junk and crime.]]

* SpecialEffectFailure:

* SpoiledByTheFormat: Most of the trainers, [[TheComputerIsACheatingBastard most notably two towards the end,]] use Pokémon that were technically available to you when the game was released. So, you'll see evolutions or pre- evolutions of Shadow Pokémon all over the place before you can snag them, sometimes way before. You'll see Spinarak all over the place, including one in the first city, but you get to snag Ariados just about halfway through. Colossseum uses Pokémon that are available in ''VideoGame/PokemonRubyAndSapphire'' plus all the Gen II ones, including ones that evolve from Gen I Pokémon that are unavailable in ''Ruby and Sapphire''.

* BestBossEver: The final battle against Evice is one of the hardest bosses in the series, but unlike some bosses, the fight contains legitimate strategies that actually has you think of your feet. The music is amazing, and highlights the end of the adventure and difficult fight ahead and the background and tension for the battle is awesome.

* MoralEventHorizon: Dr. Ein crosses this just by ''inventing'' the Shadow Pokémon system (without a shred of remorse, and actually with a desire to ''improve'' it), and [[spoiler: Evice]] just by leading the whole operation. Particularly [[spoiler:Evice, since he oversaw all these despicable actions while posing as the friendly mayor of Phenac City.]]

** Dakim has 3 Pokémon with Earthquake and Protect, and they will alternate between them so one hits the entire field with Earthquake and the other doesn't take anything by Protecting. Earthquake also hits his Shadow Entei super effectively and it doesn't have Protect, so if you're not careful he'll knock it out and prevent you from catching it.

** [[spoiler:Evice]], especially if you allow Slowking and Slaking out together. Slowking WILL use Skill Swap and Slaking will use its high base stats and freedom from Truant to destroy your team. His others are no slouch either, since they all know moves that will boost their Attack. Examples are his Salamence with Dragon Dance and Double Edge and his Scizor with Baton Pass so it can pass Swords Dance boosts to a teammate, as well as Silver Wind which hits both of your starter Pokemon. Besides from your Espeon your Pokemon are highly unlikely to outspeed his Salamence and Slaking, and there is a massive level gap between him and Nascour. Due to his unique strategies and strong Pokemon he is considered the hardest final boss in Pokemon alongside [[VideoGame/PokemonBlackAndWhite Ghetsis]] and [[VideoGame/PokemonDiamondAndPearl Cynthia]].

** In the context of the game, the encounter with [[BonusBoss Mirakle B.]] He's a LoonyFan of Miror B. who randomly shows up to battle you if you go all the way through Pyrite Cave to Miror B.'s hideout after beating Dakim ([[PermanentlyMissableContent but before beating the]] FinalBoss). Beating him gets you nothing, and unlike with Miror B., you don't even get an easy way out of the area.

** Wes himself, having history and character that are never explored beyond the fact that he used to be on Team Snagem.

** The Shadow Pokémon Nascour and Evice possess are Metagross and Tyranitar. Now, neither of these Pokémon are anything to sneeze at, but one can't really call them the ultimate Shadow Pokémon when three of the admins possessed Entei, Suicune and Raikou.

** [[spoiler:Evice]], especially if you allow Slowking and Slaking out together. Slowking WILL use Skill Swap and Slaking will use its high base stats and freedom from Truant to destroy your team. His others are no slouch either, since they all know moves that will boost their Attack. Of note are his Salamence with Dragon Dance and Double Edge and his Scizor with Baton Pass so it can pass Swords Dance boosts to a teammate. Besides from your Espeon it is highly unlikely to outspeed any of them, and there is a massive level gap between him and Nascour. Due to his unique strategies and strong Pokemon he is considered the hardest final boss in Pokemon alongside [[VideoGame/PokemonBlackAndWhite Ghetsis]] and [[VideoGame/PokemonDiamondAndPearl Cynthia]].

* ThatOneLevel:

* ViewerGenderConfusion: Nascour is easy to mistake for a woman, having long flowing hair and a sizable bustline due to being muscular (in a game where female bodybuilders are reasonably common trainers).
----

** The last postgame Shadow Pokemon you have to snag is... a Lv 20 Togetic. That's considerably lower-level than the Pokemon you ''started the game with'', and Togetic isn't a particularly strong Pokemon at that. The biggest danger in snagging is it is not accidentally knocking it out. (Which is very easy to do, as you're expected to have a Lv 65-70 team at that point)

** Multiplayer requires GBA cartridges, there's no rental Pokemon roster, and Quick Battle is only one player.

** Venus is among the most tedious bosses to fight in the whole game. Her entire team except her Shadow Suicune knows Attract, which makes Pokemon of the opposite gender unable to attack 50% of the time. Her Delcatty hits surprisingly fast and hard, and on top of infatuation, her Vileplume can paralyze your Pokemon with Stun Spore, making them only able to attack '''20% of the time''' if affected by both. To make matters worse, her Pokemon have a sudden level spike from the Pokemon you fought previously by about 5 levels, which makes the fight more difficult to those who haven't grinded in preparation.

* FanPreferredCouple: [[AllGirlsWantBadBoys Wes and Rui]].

* AnticlimaxBoss: The Shadow Pokémon Nascour and Evice possess are Metagross and Tyranitar. Now, neither of these Pokémon are anything to sneeze at, but one can't really call them the ultimate Shadow Pokémon when three of the admins possessed Entei, Suicune and Raikou.

** Ein has three Confuse Ray users and two Toxic users to try and hax you out of turns and stall you out of HP with the passive Poison damage. His Lanturn and Huntail know Rain Dance to boost their Water attacks (and give Huntail a Speed boost since it has Swift Swim) and give Raikou and Lanturn [[AlwaysAccurateAttack 100% accurate Thunders]]. His team is also about 5 levels higher than the next strongest trainer you fight, so he may also overpower you by level advantage if you haven't been grinding.

* FridgeBrilliance:
** At the beginning of the game, Es Cade promises to investigate Cipher for you. Yet throughout the game, he never once calls you to give you new information, and any time you visit him, what info he does have is stuff you've already known for a long while. At first it seems like he's incompetent, until [[spoiler: it is revealed that he's the BigBad]].
** Whenever you snag an Admin's Shadow Pokémon, in future battles, they will have a replacement for it. Gonzap will as well. When you fight Fein at the end, the man who is deliberately framing Wes for assault, his team (with the exception of Shadow Togetic) consists of the replacement Pokémon used by Gonzap and the Cipher Admins.

* BreatherBoss: After several tough rematches with the four Cipher Admins and before the battle with the head of Cipher, [[spoiler:Gonzap]] is actually not that tough at all. He even has some ArtificialStupidity, spamming Earthquake on the three of his Pokémon that have it, even though every time he does it, it knocks big chunks out of whoever else he has out at the time. Using Flygon makes it even funnier, since Levitate makes it immune to ground moves. His Shadow Skarmory can be a pain to catch, though. (Unless you swap-dupilicate the Master Ball, then it's a cinch.)

** The [[https://www.youtube.com/watch?v=um0pkcPFCLs final boss theme]] is probably the most epic theme in the history of the series.

* MemeticBadass: Wes.
