* AccidentalInnuendo: One of the Team Rocket members in Stadium 2 has a Wobbuffet nicknamed... Wobbu'''fap'''. It's ''even worse'' considering what Wobbuffet looks like.
* AntiClimaxBoss: Mewtwo in ''Pokémon Stadium'', 1 of him against your 6 (and said 6 can include 1 of him)? Pitifully easy compared to the cheaters you have to beat to reach him. Only using rentals makes things harder, but he's still much easier than the previous foes.
** The Cooltrainers in Johto Gym Leader castle are the last cronies you face, and they are a complete joke in both Rounds 1 and 2, especially the Male Cooltrainer. The Female Cooltrainer really wants to utilize Sleep moves as her main strategy, except it's crippled hard by 2 main things: Sleep clause, and 1-3 turn wakeups, which even makes her Prime Cup battles rather underwhelming in comparison with the other fights. The Male Cooltrainer literally uses first stage starter Pokémon right before Clair, while in Round 2, he uses ''second stage'' starter Pokémon, though they all do have some Counter moves, without much of the stats. What makes this egregious is that they are intended to be the elite mooks of both the handhelds and especially ''Pokémon Stadium 1'', and the fact that the commentary the announcer gives to the Male Cooltrainer: "He is sure to be a tough opponent!", especially since Pryce's Gym trainers, Team Rocket, and even Chuck's OHKO-abusing underlings are more dangerous, even in Round 2.
* BreatherBoss: Jasmine and the Kanto leaders in ''Pokémon Stadium 2'', due to being the only trainers in their gyms. They're not neccesarily easy, but at least you don't have several other trainers to battle again if you lose to them.
* EasyLevelTrick: Having trouble with Jasmine constantly switching? Entry hazards and trapping moves work very well, since her Pokémon cannot learn Rapid Spin.
* GameBreaker: ''Pokémon Stadium 1'' Substitute Mewtwo is what you get when Substitute has been upgraded to Block status (which didn't happen in the original handheld titles), OHKO moves, Explosion, sometimes Wrap moves, and stat reduction moves. It does reduce HP, but Mewtwo has Recover, making it near untouchable. Add in Amnesia (which raises its Special Attack and Special Defense) and Psychic (which no Pokémon is immune to, and even when resisted, 30% Special drops), and nothing in the game bar a lucky speed tie (Mewtwo or Jolteon), or a Thunder Wave Electrode can even inconvenience this monster. It is the single most broken moveset in ''Pokémon'' history.
** ''Battle Revolution''[='=]s Sunset Colosseum runs on a very annoying Select Battle where you and your opponent pick from the same pool of Lv 30 Pokémon. Each of your opponents chooses one of six pre-determined Pokémon, which you are also allowed to pick out. Girl in Love Grace has a Dragonair and a Gabite, both of which have Dragon Rage, and ''nothing[[labelnote:*]] that can appear at the Colosseum[[/labelnote]]'' has more than a hundred HP at level 30. So long as she does not pick both of them and have them both out at the same time, good''bye'', Little Girl.
* ItsShortSoItSucks: A common complaint about ''Battle Revolution'' is that beyond its Battle Frontier-like area, there is pretty much nothing else to do the way there is in the ''Stadium'' and ''Colosseum'' games.
* NarmCharm: The announcer is either the shining example of this, or he's TheScrappy.
** In ''Battle Revolution'', poisoning will cause him to say "___ is losing its health!" Mind that he says the last three words in a very dramatic way, as if he's about to break into tears.
** In the ''Stadium'' games, Nidoking acts like LargeHam. When it enters battle, it roars and laughs to the sky. When it gets knocked out, it dramatically puts its hand on its chest and gives an expression as if to say, "And....scene."
** Vileplume has a knock out animation similar to Jynx, in that it mysteriously disappears underneath its flower. However, it becomes pretty funny once Vileplume's petals start thumping against the floor, almost as if it's "tapping out".
* NightmareFuel: The one-hit KO animations, especially when they connect.
** [[http://www.youtube.com/watch?v=ApPJACXCdoM Jynx's fainting animation]], in which it cries, suddenly freezes ''and its entire body disappears''; that is except its hair, which simply drops on the ground. ''Brr''.
*** [[http://youtu.be/VGPlatsBbMc?t=44m48s Misdreavus' fainting animation]] is similar: it ''blinks out of existance'' with a Tear Jerking look on its face, leaving its string of pearls, which falls to the ground and ''shatters.''
** When Arceus or Giratina use Shadow Force. ''Especially'' [[http://www.youtube.com/watch?v=tNWo2qa8Sc4#t=1m13s Gira]][[http://www.youtube.com/watch?v=tNWo2qa8Sc4#t=2m32s tina]].
** [[http://www.youtube.com/watch?v=5CuogykovhA Jigglypuff's fainting animation]]. It ''deflates.''
** [[http://www.youtube.com/watch?v=0yfHCYajdR4 Kangaskhan]] looks like she's ''choking'' when she faints.
** When Magnamite, Magneton, and Porygon fainted, their entire bodies broke apart. All three were updated in later games to simply fall over with "X" eyes.
** Abra's creepy spasms whenever it got knocked out.
** The Gym Leader Castle map in the first ''Pokémon Stadium''. You have a path with 8 gym towers in [[http://bulbapedia.bulbagarden.net/wiki/File:Gym_Leader_Stadium.png a cavernous area]] with smoke all around that seems to lead into a volcano that actively has smoke and lava pouring out of it. Then, when you beat the 8 Gyms, the smoke from the volcano reveals the Elite Four Castle built over the volcano.
*** When you take a look on [[http://www.youtube.com/watch?v=kLqVPeZaRuU&list=ELkuxMrWAohAQ the Elite Four Castle map]], you'll see a ghostly-looking Venusaur on the left of the path to the Elite Four Castle entrance. The creepy cavern/volcano vibe may be why the entire Gym Leader Castle in ''Pokémon Stadium 2'' was made to be less scary in appearance.
* SidetrackedByTheGoldSaucer: Minigames in the ''Stadium'' games. Pity ''Revolution'' didn't have any...
* TearJerker: Some fainting animations can come across as this, especially if they're of your favorite Pokémon.
** The final trainer of Prime Cup Master Ball in Pokemon Stadium 1 is a Male Cooltrainer with a '''Mew''', in both rounds. Round 2 kicks it up several notches, as his Mew has higher stats, '''softboiled''', and overused competitive teammates like Tauros, Exeggutor, and Starmie. To a lesser extent, the Female Cooltrainer in round 2 Master Ball, as she's the only one that can make the gamebreaking Substitute Mewtwo users think twice. How? With an Electrode that will outspeed and paralyze Mewtwo before it sets up, or just power through with Body Slam Snorlax. Good luck beating those two, especially with a rental team.
** '''Any FinalBoss with a Snorlax''' in any of Pokemon Stadium 2's Round 2 cups. Snorlax is extremely versatile, extremely hard to kill, and can easily destroy your pokemon from the transfer packs (Including Mewtwo), especially rentals. Gym Leader Castle’s final boss, Pokemon Trainer Red’s signature pokemon is a Snorlax, and even among a team of legendaries, it is by far the most dangerous pokemon, but is covered well by the two non-legendaries. Poke Cup Master Ball Finalist Pokemaniac Pedro’s Snorlax is level 55, has leftovers, and uses a Belly drum/Rest/Snore/Earthquake combo, and if he rests after belly drumming, you have already lost, but he could choose the much “easier” level 55 Dragonite instead. There is a reason why you never face Snorlax in round 1 Pokemon Stadium 2… outside of Challenge cup Master Ball.
** Compared to what a joke he was from the games, Pokemon Stadium 1 included, Round 2 Pokemon Stadium 2 Bruno ironically became arguably the hardest boss in Johto Gym Leader castle, as his incredibly powerful Machamp is paired with very powerful physical attackers. It is bulky, has insane coverage, and it hits very hard with Cross Chop and Rock Slide, but it also has Quick Claw, and worst of all, Fissure, (ironically, it was a useless special moveset for Bruno’s Machamp in Red and Blue) that can ruin your day. He's no slouch either if he selects Kangaskhan and Blastoise in round 1.
** The level 20 Alakazam in Pika Cup, who knows Psychic and Thunder Wave. Doesn't sound that intimidating, right? ''Wrong''. He's genuinely impossible to beat with rental Pokémon barring miraculous freeze hacks that you'll have only one chance at pulling off or else you die. The guides even advise the player to use a transfer pack, or pray that your opponent end up being the level 20 Dragonair.
* ThatOneLevel: ''Battle Revolution''[='=]s Neon Colosseum. Colosseum Leader Rosie is the only one who can put up a fight with her own Pokémon; everyone else has horrible Pokémon with horrible movesets. The problem with this is that Neon Colosseum runs the Fortune Battle, which means that all twelve Pokémon on your pass and your opponent's pass go on a roulette wheel, and you throw Poké Balls at them. Even the Pokémon on the Rental Passes are better than your opponent's. There's a seven-or-eight slot delay between your pressing the button and the Ball landing, which means you need to be careful if there's someone particular you want to pick up. And since your first time through is a mandatory Double Battle, you need to throw your first couple Balls in preparation for ''any'' combination your opponent might catch. Yes, Sunset Colosseum runs a very randomized Rental Battle, but at least you're sharing the disadvantage with your opponent!
* ThatOneSidequest: ''Pokémon Stadium 2''[='=]s Challenge Cup Ultra Ball, especially in Round 2. There are several issues with this particular cup compared to every cup in the game:
** The problem with this division and level in particular is that the random selections are completely imbalanced. For starters, there are NO fully evolved Fire-types, the only Fire-types you get are Charmeleon, Quilava, and ''Ponyta'', whereas the other starter mid-evos are available in Great Ball. Compared to stuff like Skarmory, Quagsire, Kadabra, Hitmonlee and Clefable, they are terrible selections.
** The second issue is the standard movesets: You usually have two attacking moves, one of the primary type, and if you are dual-typed, the secondary type, or a coverage move if you are not, or don't have moves. Then its a stat/status-related move, and a defensive move. Many enemies, with a few exceptions, use this basic setup. However, they can give really low-powered moves like Tackle or Bubble if you are unlucky, or high-powered moves with low accuracy. This cripples Pokémon choices like Shuckle, Sneasel, and Chansey, who can't use their STAB moves effectively.
** The other thing is that you can't use ANY recovery moves like Recover and Rest, so if you can't get a Pokémon with Safeguard or Substitute, you are more susceptible to status moves, and the majority of trainers in this cup use the most status moves.
** The most pressing issue are the Round 2 trainers, and to some extent, Round 1. Only two trainers are relatively harmless compared to six.
*** In Round 2, the Male Executive in the second fight has a Toxic/Protect strategy that will run through many random choices, regardless of stats, along with other moves.
*** The worst by far is the Guitarist in the fourth fight, who gets off on paralyzing your team with a difficult combination of Electric-types, Grass-types with Stun Spore, and other random types that can have Thunder Wave or Body Slam.
*** The fifth fight, a Fisherman, has a mostly Rain Dance-based Water-type team with Ice moves, with the only non-random signature Pokémon Quagsire that he will ALWAYS have, and its type synergy is incredibly solid against many PokÉmon.
*** The sixth is a Swagger-abusing team, with powerful Psychic-types that are extremely difficult to wall. Your only Dark-type selections are Sneasel, with crap Special Attack, and Murkrow, who dies to everything but Psychic and can even die to Swagger damage.
*** The seventh is a Normal-type-using Female Executive, who actually breaks the Challenge Cup standard moveset structure among teams, and uses more than two kinds of attacking moves. Her Normal-types has some dual-type coverage, and with their generally high stats, are the powerhouses of the cup. And she likes to flinch you if she has the speed advantage, usually with STAB Headbutt or Hyper Fang.
*** The eighth battle has a Juggler with a completely random team, but his AI tends to be higher than the other trainers, and you probably have no continues left by this point.
** At least in Master Ball Round 2, you could fish for Snorlax, which no matter what moveset it has, it is a reliable tank that can use every move to its advantage, and can power through every trainer except the Double Teaming status-spamming Scientist and the Gentleman and his almost omniscient AI compared to every enemy in the game, who are the most dangerous trainers in the Master Ball division. You get no such Pokémon in the Ultra Ball division, and there are SIX dangerous trainers.
