Robopon/YMMV

"Tail: I lost to Cody and lost everything that matters to me..."
 * Alternate Character Interpretation: Cody makes a lot of morally questionable decisions throughout both games, and can be seen as an Anti-Hero.
 * In the first game, his goal isn't to be a master or save the world. It's to build up his grandfather's company, which he was put in charge of. He can refuse to help his girlfriend and a kid who is being picked on by bullies. Cody also joins the local evil army and wins at every one of their factions, then defeats their boss. He can sell his Robopon, who are stated to be sentient creatures, for money. At the end, he's the most powerful Robopon trainer on Porombo Island, and when he goes to a tournament in the sequel, he leaves all of his friends at home.
 * In the sequel, Nick D. tries to guilt trip Cody into giving him the X-Stones because he needs them to provide money for the orphan kids at Chapel Academy. You defeat him every time. Dr. Don and Sam continually berate Cody for wrecking their time machines. Eventually, it drives Don insane. Then Cody arrives on the bad guys' Battleship 20 years in the past. He does not prevent it from blowing up an entire town, but does blow it up with the villains inside, nearly killing Zeke and causing Zeke's father to berate him. At the end, it's revealed that Cody defeating the villains at the end of the game caused their actions in both games thanks to time travel.
 * Prince Tail's father can also be seen as a villain. Dr. Zero is right when he says that Tail's father won the throne by cheating; he had defeated the King, but was attacked and left for dead, leaving the royal family to claim the title.
 * Crowning Music of Awesome: Not so much awesome as relaxing, but the Poro Village music from the first game can lull you to sleep.
 * Also from the first game, the music in caves, and the music when you're riding Cycool or Speedy.
 * The Battery Clatter music in the second game, and the regular trainer battle music.
 * Evil Is Cool: Dr. Zero. Just look at him.
 * Game Breaker: In the first game, Golden Sunny/Silver C-Cell, which can only be obtained in a Fetch Quest, and the hidden Robopon Scar, which is found only in the game's toughest dungeon. The Seabee you get for rescuing Darcy can evolve into Draco, which is also one of the strongest Robopon in the game.
 * The Rust status effect causes major damage at the start of a turn and has a high chance to stop you from attacking. This was nerfed in Robopon 2 to only cause damage and at the end of a turn.
 * Golden Sunny knows the Alpha moves, which are extremely strong..
 * The second game has Nebulus, who can only be obtained by Link Sparking.
 * Hilarious in Hindsight:
 * One of Pokémon Black and White's genre-deconstructing tropes was in the ending, where . Robopon did that years earlier, in the first game.
 * In Pokémon Ruby and Sapphire, a new feature was the ability to dive underwater. You used this to track down the villains. In the first Robopon, you can dive underwater as well: there's no bad guys there, but there's a health spa!
 * The first Robopon games were Sun, Moon and Star versions. In 2016, Pokémon Sun and Moon were announced. Robopon fans are quite amused at this.
 * Most Annoying Sound: In the second game, a particular "song" is nothing but distorted synthesizers and a constant drumline, seemingly calculated to be as annoying as possible. While only played in a few, short scenes normally, it becomes a huge problem if the RNG hates you. Why? The mushroom spirit that changes the battle music changes it to this, for 33 battles.
 * Most Wonderful Sound: The VWEEP noise when you collect a hidden item in the first game, and the sparkling noises when you examine a teddy bear.
 * Some Anvils Need to Be Dropped: Robopon 2 pokes fun at a lot of moral lessons, but Miho's speech about listening to another person in a relationship and not trying to change them to suit you is one the game takes seriously and hammers in with the force of an anvil... for good reason.
 * Surprisingly Improved Sequel: Robopon 2 did a much better job of breaking away from the Pokemon mold by making battles four on four, and introducing the love/hate oil system, in which Robopon of a specific oil type (either A, B, AB, O, or ?) "liked" Robopon of certain oil types and "hated" Robopon of other types. Using this system in tandem with any software on hand made it possible to teach almost any Robopon skills that could target every enemy on the field, or every one of your allies, and is an integral part of the Metagame. The game was also much more humorous and meta than the first, while keeping a serious tone for the endgame.
 * That One Boss: Mr. Wild and Prince Tail in the first game, and Insector in the second.
 * Dr. Zero, both games.
 * In the first game, Kamat's army. Without being familiar with or good at the minigames that were optional up until this point, some players may have a hard time getting past the challenges, particularly the Jumper minigame, since it revolves solely around the Speed stat.
 * Optional boss Hunter..
 * Dr. Zero. Senior. Even if you thrashed Zero, Jr., Zeke and the Bonus Bosses, he can kill you quite easily.
 * That One Level: In the first game, Grease Mountain is the proverbial brick wall. Things only get harder from there.
 * In the second game, the Galileo Windmills, Dreamless Island,, , the Neon City sewers, and the Pond Garden tend to frustrate players very thoroughly, due to either a) the enemies, b) the layout, c) bosses, or d) all three at once.
 * That One Sidequest: Averted in the first game's Elite 8 quest for Golden Sunny/Silver C-Cell. You'd think getting one of the game's Olympus Mons would be difficult, but all it is is a trading game. The Robopon you start the trade with, Gidget, is easy to find and catch too.
 * Played straight with the Brownie sidequest. You go to a specific forest at around 5:00 p.m., and you have to arrange rocks to make several numbers. You're told which ones to make, but only a few rocks can be moved at all. And you do this while being attacked by wild Robopon.
 * Unintentionally Sympathetic: Dr. Zero in the second game, . This may have been done on purpose.
 * This also applies in the first game to a lesser degree. Dr. Zero is right when he says that Tail's father won the throne by cheating: he had defeated the King, but was attacked and left for dead, leaving the royal family to claim the title.
 * The Woobie: Prince Tail, in the first game..
