YMMV: Pokémon Rumble

  • Awesome but Impractical: The special trait Steady. It No Sells any stat changes, including friendly ones, making stat-boosting or health restoring moves pointless. In World, even the items the Miis use on your Steady toy when they tag along will be for naught. Subverted if paired up with a move that normally decreases the toy's own stats, like Close Combat or Overheat, as the stat drop is negated due to the special trait.
  • Awesome Music: Even if the soundtrack is a little short, this series has many Ear Worm music.
  • Demonic Spiders: Electric-type Pokémon in general, mainly due to the fact that they can reliably inflict paralysis. Unlike the main series games, paralysis completely immobilizes your Pokémon, giving everything in the vicinity a chance to wail on you. And since everything seems to come in packs...
  • Nightmare Fuel: Rumble Blast's final boss, which is a rusted key that controls Pokemon. Despite not being a Pokemon, it gets its own cry!
  • So Okay, It's Average: The games was given average reviews by critics. They generally praise Pokémon collecting but criticized the game play and Pokémon models reused from My Pokémon Ranch.
  • Scrappy Mechanic: In World, your Pokémon will automatically attack if an enemy is close. This makes dodging difficult, especially for attacks with lots of lag. Fortunately, this can be turned off in the options.
  • That One Boss: Staraptor in Blast for sheer speed.
    • Most Legendary Pokémon also apply, thanks to their attacks being outrageously hard to dodge.
    • Slurpuff in World. With a swarm of infinitely respawning Swirlix that use Attract (which homes in, stuns you every time one hits you and destroys your attack power) and a move that can regenerate its health, and then you factor in the time limit when facing it in the "Restaurant Opening" challenge...
    • Sylveon, also in World, is an odd example due to its flunkies being Audino. Audino's sole "attack" is that it heals the area around it, making Sylveon a pain in the ass if you're using something that only has close range attacks and you neglect to take out the Audino first. However, this also makes Sylveon the easiest (albeit tedious) toy to collect, since it has essentially unlimited health, allowing you an infinite amount of time to attempt to wobble it for a guaranteed capture.
    • Lugia, yet again in World. Combine the fact that it boosts its Attack and Defense and the accompanied Octillery use Octazooka to lower your hit ratio (in other words, making all attacks take longer to execute)... Good luck trying to catch it.
    • In terms of catching Pokémon, Aegislash. Slow to get to because of a balloon that takes five hours to refill, a one-in-five chance of landing on it without gems, and a requirement of at least two stars, but that's comparable to many tougher Pokémon. The problem is that thanks to its stance shift, it never goes into a cooldown phase and therefore cannot be wobbled. At all. Expect to make many attempts before one of them deigns to sparkle or come along quietly.
  • That One Level: In general, the Battle Royales has you fighting waves after waves of enemies that always like to Zerg Rush you if you didn't act fast and the battles are Timed Mission here.
    • Any King Challenges in World can give you the headache if you don't have the required Power Level for your Toy Pokemon.
    • In World, the aforementioned "Restaurant Opening" challenge from above is no joke. It's a surprisingly hard Escort Mission where you have to protect your Mii while be under the unforgiving time limit. The enemies are Genre Savvy to beat up your Mii, while it was just standing around like a sitting duck, forcing you to fight groups of enemies while pushing the Mii away from their attacks. Not only that but you will be outnumbered if you don't kill them right away and you have to fight like 2 sub-bosses, Sceptile and Tauros, traps, small castles that make more enemies appear, cannons that can lower your speed if you got hit, bombs falling from the sky, and freeze cannons that can and will make you Frozen, before reaching to the end of the level. Slurpuff and the Swirlix horde are annoying to fight as the former heals itself after attacking while the latter spams Attract at you, preventing you from attacking as well, making you wasting all the time you need. Good luck, you gonna need it!
    • A level following that has the player protecting Diancie, and all the Pokemon that appear target it, and only it, until you directly intervene. While one of the challenges has the player using supereffective Fairy attacks, those are viable against half the Pokemon in the level (Sneasel, Weavile, Purrloin, Liepard, Absol), with the rest as Normal and requiring a bit more effort. Did we mention that the Meowths all use Fake Out, which can flinchlock you and Diancie if sufficiently swarmed? Joy.
      • It gets worse - in the postgame, you've got a level where you have to protect Mega Diancie, and the enemy Pokémon you have to deal with are a mix of types (Inkay, Malamar, Shroomish, Breloom, Sharpedo, Carvanha to name a few in the first area). The first area has three bosses in the form of Ursaring, Beartic and Pangoro, and much like the first 'Protect Diancie' level, all enemies will naturally target it instead of you. When you get past that and go to the next area (thankfully in this mission, Mega Diancie's health is restored to max when you change areas), you've gotta deal with more enemy mons and a boss fight with an INSANELY strong Mega Lucario and towers that spawn Lucario. To make matters worse, its defense is off the charts, so even having a Pokémon whose attack strength is in the 2100 range will only chip off small portions of health. You probably might need to get your rank into the high 70s and get some Pokémon with certain Special Traits to secure a pass on this one. Also one of the level's challenges is to get a 100 or more combo - considering enemies can take a few moments to spawn or the fact that you'll need to constantly swap Pokémon to have the right type matchup, good luck.
    • One level, which if recalled correctly is the last in the main story, has a starting area where to pass on to the next part, you've got to deal with a Wobbuffet. The moves it has on hand are Destiny Bond, which KO's your Pokémon should you KO Wobbuffet whilst it's in effect, and Counter, which will deal your Pokémon damage when you hit Wobbuffet. Keep in mind this is a timed level, so if you don't have a Pokémon that can potentially murder it in a few hits, you've gotta wait for Destiny Bond's effect to wear off once cast less you really want to pay 2 Poké Diamonds to continue on, and when that wears off it'll probably still have Counter active, so you'll have to be doubly careful you don't KO yourself from shared damage.
    • 'World Championship X', which appears in the post game, is a living hell. Enemy Pokémon with insane attack and defense, status-inflicting moves, so fast you have next to no time to swap out. To further make it harder, it has the usual 'don't swap out' rule, as well as trying to clear it in 220 seconds and clearing it with only 'Pikachu'. Good luck - you're REALLY going to need it!
    • The "Dragon Marshall Advance" challenge in World. Have fun fighting a multiple hordes of enemies, and then fighting several Mega-Evoloved Pokémon that are all backed up by their own small armies of endlessly-respawning enemies! Granted, you can destroy the towers to make the respawning stop, but it unfortunately eats up time and leaves you open to attack.
