* AccidentalInnuendo: One of the Team Rocket members in Stadium 2 has a Wobbuffet nicknamed... Wobbu'''fap'''. It's ''even worse'' considering [[FreudWasRight 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.
* BreatherBoss: Jasmine and the Kanto leaders in Pokemon 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 Jasmine constantly switching? Entry hazards and trapping moves work very well, since her Pokemon cannot learn Rapid Spin.
* 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 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 pour 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: 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.
** Some fainting animations can come across as this, especially if they're of your favorite Pokémon.
* ThatOneBoss: There are many battles that could end up as that one boss in both Stadium games, and then there are standout bosses here that make you want to bring a transfer pack with your personalized and Stat EXP trained mons, particularly in Round 2.
** Pokemon Stadium 1
*** The most infamous one boss of pokemon stadium is actually a trainer class that you normally find very early in the handhelds: The Lass. She is a notable case here because she is one of the very few recurring trainers like the bug boy (bug catcher) and the lad (youngster), and the first two are still easy leveled trainers even in round 2, but the Lass is a different story. In round 1, she signals an unbelievable difficulty spike, because she always has two signature pokemon that are much higher leveled than the rentals, and are usually very powerful pokemon species in that particular cup. In petit cup, has this obnoxious eevee, that, if you don't have a gastly as a rental pokemon, will abuse sand attack and waste your rentals with double edges, and for rental geodudes, she will abuse toxic and sand attack, while wittling you down. Her partners aren't to be underestimated, since they can cover rental gastly, and abuse evasion moves. But the worst is Pika Cup. She isn't the first trainer in that cup to use a level 20 (That would be the hiker, who has a slow, 4x weak rhyhorn as his signature, but treat it like a level 15 rhydon, and its easy); she is the first one to use 2 level 20s, and they are fully evolved behemoths of water types, with some fully evolved level 15 members, including a psychic type, and a meowth as the resident "joke" pokemon she rarely uses. Of the two level 20s, Tentacruel is so much worse than Gyarados, since gyarados is outsped by the rental raichu, and you could pray that thunder hits, but the tentacruel outspeeds every rental, has the highest special attack in the cup, surf, and it has wrap, which will often derail any attempt to even attack this monster, let alone defeat it. This is round 1 by the way. She upgrades to two level 20 dragon rage users, and fully evolved teamates at level 15. If you are playing rentals in round 1 for the first time, the words from the announcer "Oh its Gyarados/Tentacruel! Oooh... this one looks formidable..." accurately sums up you of what is to come from the Lass.
*** Another notable trainer is the Gambler in certain rounds, usually master ball. His gimmick is using luck based moves, and the most dreaded of all is the OHKO moves. His strategy involves speeding himself up, usually agility, or slowing you down, usually with paralysis attacks like body slam, glare, or thunder wave, or even bubblebeam hax. Then he starts abusing horn drill, and there have been incidents where all of them hit. One very scary pokemon on his team is Tauros, it is naturally very fast, actually has two OHKO moves, alongside two perfect coverage moves body slam and earthquake, so it actually can destroy your party without even resorting to horn drill or fissure with critical hits. Fortunately, substitute mewtwo, with good stats and amnesia, can beat him with a little bit of luck, but otherwise, good luck. You will need every bit of it against the Gambler.
*** The final trainer of Prime Cup Master Ball 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, who is the only one that can make the gamebreaking Substitute Mewtwo users think twice, 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.
*** One particularly nasty example is the Fisherman in the Round 2 Pika Cup, who can select a ''level 20'' '''Alakazam''', which is ironically one of the few legally accessible pokemon in that cup and isn’t even fully maxed out, especially on the Fisherman’s team with lv. 15 Golem, but it is ''by far'' the strongest pokemon in Pika Cup, and effectively functions as an instant win nuke against rental pokemon, so you better pray he never picks this if you are using rentals. The Lv.20 Alakazam can give even your Lv.20s a run for your money with thunder wave. It is extremely telling that your rentals have a better chance against the semi-illegal Lv.20 Dragonair with Dragon Rage, than a legal yet fully evolved psychic pokemon that has a very high crit rate, can always outspeed, and OHKO or 2HKO nearly every rental.
*** The Psychic in Round 2 Poke cup Master Ball. Unlike other cups where you could use transfer pack to get level 20s/30s for Pika cup and Petit Cup respectively, or use Mewtwo in Gym leader castle and Prime Cup, you won’t be able to brute force your way against this final opponent with such strategies due to level and pokemon restrictions. In the tournament cup with the most gimmicks, The Psychic has a high quality Psychic monotype team with some very high stats that can overpower many pokemon, (and not just rentals) with their broken psychic type attributes, such as status, high critical hit rates, high specials, ''Amnesia Slowbro'', 30% special dropping attacks and almost no weaknesses apart from a few secondary typed psychics. And Hyper Beam is at its worst in this game, since it has to recharge even if it KO's a pokemon at best, or worse, even if it ''misses'', so the psychic types can dominate normal types as well. Notably, yet unsurprisingly, Poke Cup Round 2 is the only tournament cup in pokemon stadium that has a different finalist from round 1 (which was the old man).This is considered to be the hardest battle in Pokemon Stadium for many transfer pack users, and as for rentals? The fastest rental, Electrode, is ''out-sped'' by the Psychic's Alakazam and Starmie.
** Pokemon Stadium 2:
*** '''Any trainer with a Snorlax''' in Round 2, and are usually among the last enemies you face in the tournament. Snorlax is extremely versataile, 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. Prime Cup Semifinalist Skier Kathy proved to be ''much'' harder than the finalist (who has a Machamp, ''Raikou'' and '''Celebi'''), because her Snorlax has the most versatile moveset, and not many openings. It is the cornerstone of a very powerful team with Suicune, Kingdra, Jolteon, Tyranitar, and Scizor (who she almost never uses), and it's return attack is at max happiness, so enjoy 153 base damage from 110 base attack. 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. The only comforting thing about this is that none of them use Curse or Sleep Talk Movesets.
*** Pokefan Rex from Little Cup in Round 2 is several leagues above the other trainers in difficulty. His little cup team that consists of many “baby” pokemon that were once fully evolved in gen 1, like Chansey, Porygon, Onix, and especially '''Scyther'''. His elekid and slowpoke are no slouches either. This considered by many to be a difficult cup because many trainers have “box tricked” stats, and despite a breather semifinalist, he can obliterate rentals with his ''extremely'' overpowered team.
*** Pokefan Baxter, from Poke Cup Master Ball is one of the few semifinalists that prove to be harder than the Finalist, due to a very powerful team with no particular game winning strategy, but no openings either. He has a speedy thunder wave user (Electrode), two very speedy sweepers (Aerodactyl and Alakazam), the most powerful physical attacker in the game (''Thick Club Marwowak''), and a bulky wall (''Suicune'') that can just outright overpower your teams. Rapidash is the weak link of the team unless it is equal or higher leveled than you, in which case, it can simply Horn Drill your team.
*** Compared to what a joke he was from the games, Pokemon Stadium 1 included, Round 2 Pokemon Stadium 2 Bruno ironically became the 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.
