These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Spyro the Dragon
The classic trilogy
Best Level Ever: Metropolis. This is the last listed regular level in the second game for good reason; not only are the enemies amazing, it contains the first miniboss in the series and a combo powerup with Superflame and Superflight. You then use it to fire down two waves of sheep saucers.
Ensemble Darkhorse: The Egg Thieves in the first game. The second game had only a single thief challenge in Shady Oasis, but the third game had a bunch (usually involving supercharge ramps).
Ripto has his moments.
So does Hunter, who progressed from minor aide to partially playable after Ripto's Rage and is the only character besides Sparx to make it through from the original trilogy to the Legend series, albeit in a rather different form.
Sheila is this among Spyro's playable friends in the third game.
Even Better Sequel: The second game is widely considered to be this to the first. There's quite a Broken Base on whether the third is this to the second.
Fridge Brilliance: Those skateboarding rhynocs in Lost Fleet? They're basically teenagers who hang out in places their parents don't want them to go so they can skate.
Harsher in Hindsight: Refusing to pay Moneybags in one of the levels in Year of the Dragon will make him say "What are you saving your money for, another sequel?" Better pay up...
Jerkass Woobie: Bianca in Year Of The Dragon. Steals the entire colony of dragon eggs for the Sorceress, and smack talks Spyro for most of the early stages of the game. In reality though, Bianca is only doing so to preserve magic in her world, having no genuinely harmful intent, and is usually too Adorkable and downtrodden to come off as particularly fearsome. She pulls a Heel-Face Turn when repulsed by the Sorceress' real intent for the eggs.
Moral Event Horizon: The Sorceress planning to kill 150 baby dragons just so she could use their wings for an immortality spell. And what's worse, she didn't actually need to kill them.
To clarify, she didn't have to kill them, "It just stops them from wriggling so much!".
Even without having to kill them this crosses the line. It's implied she wanted to tear them off while they're still conscious.
One-Scene Wonder: The Ice Princess, who has a very charming design and attracted a small fandom, appears only to give the player a single mission in A Hero's Tail.
Take That, Scrappy!: One mission in Spyro 3 involves chasing down Money Bags after he reveals his plans to sell a dragon egg. This mission results in you ramming/torching him around Midnight Mountain, getting back ALL the gems he charged you throughout the game.
That One Boss: Ripto in Ripto's Rage isn't especially difficult, but it's considerably tougher than the game's previous bosses and much, much harder than the final boss in the first game. He has three stages and depending on your luck, each one can last quite a while.
Spike, the vaguely Cyberdemon-looking second boss of the third game. Much, much harder than the boss before him, and quite a bit harder than the boss after him.
There's an ox miniboss fight in Metropolis in the second game that takes place on a frozen walkway. The ox stands safely on a raised platform and throws bombs at you. To beat him, you need to align yourself just right so you can use your flame breath to knock enough bombs back at the ox.
That One Level: In Spyro the Dragon, Tree Tops. Oh God, Tree Tops. The level appears simple enough, but in order to get to one dragon and a clutch of gems, the player must take a completely unintuitive (and difficult to pull off) route via the supercharge ramps.
Spyro himself lampshades how hard it is when you rescue the dragon trapped in one of the thieves' house.
"Yea, well you could've found an easier place to get stuck!"
Haunted Towers from the same game has a whole area which is entirely hidden from the rest of the level - and again, only a difficult and not-hinted-at supercharge will lead you thee.
Spyro 2 has Fracture Hills, a level that contains a notably frustrating Escort Mission. Annoyingly, if you beat it at the first opportunity, you won't be able to complete the subsequent mission until you've unlocked the Headbash - forcing you to come back to the level and replay the Escort Mission at a later date.
Worse if you kill them with superflame before doing anything else. Turns out the guy you had to escort was supposed to take a route that included every Earthshaper in that area anyway, despite Hunter being next door. However, you get a Crowning Moment of Funny by doing so in that Hunter, not noticing there are no Earthshapers outside the door anymore, makes the Orb challenge end as soon as he exit said door.
The flight levels/speedways can also be frustrating until you are familiar with their layout - the flight levels in the first game are particularly difficult, but they got easier in Ripto's Rage and Year of the Dragon (where there is a clear optimal route for taking out obstacles, and in YOTD, Sparx outright tells you the order to tackle them.
Lost Fleet's skateboard challenges.
That One Puzzle: The seed-planting challenges in Ripto's Rage and Year of the Dragon require quite a bit more strategic thinking than usual. The one in YOTD is particularly troublesome, because even when you know what to do, it requires some very difficult jumps.
The yeti boxing match in YOTD. Hoo boy. Learning a completely new and bizarre boxing layout against an opponent with no discernible pattern. And you have to do it twice, second time takes 3 rounds.
The annoying part is you have to beat the stupid yeti in 2 rounds to get the whole epilogue. We'll notify your next of kin.
To compensate however, you get a unique reward solely for completing it, plug in a second controller after earning the challenge's egg and you can have a two player rematch.
The rather annoying challenge in "YOTD" has Spyro swimming in the long tunnel at super speed to get to the dead-end where the egg is at and if you got hit by a wall or a rhynoc, you'll have to start all over again. Have fun.
Don't forget another section with the psychopathic monkey at Dino Mines. You can't move and you have to shoot every dinosaur in sight or else they're hit you. Near the end you'll get overwhelm by them as well. It would have been better if it's not an First-Person Shooter minigame.
TROUBLE WITH THE TROLLEY, EH?note A horrible sidequest in the 2nd game in which you must collect 50 gears on a trolley. Sounds easy, right? It's not. The camera is rigged and the jumping is counter-intuitive. Hitting the signs is the worst part, though. Have fun!
Skylanders' Spyro has broken it again. Some say it completely ruined Spyro because they don't like Spyro's design while others say they like the look of the game itself and Spyro's look isn't that bad.
Enemy Mine: Original and Legend fans are generally in agreement that the Skylanders games just don't exist.
Let's not get started on the Game Boy Advance games. While some like them (including Ted Price) and consider them faithful to Insomniac's work on the series, others hate them for no real reason due to not being made by Insomniac.
Be very very careful if you mention Cynder at all.
Draco in Leather Pants: The biggest of the offenders being Ripto, Red, and Malefor (and possibly Dark Cynder if you want to count her in). So bad with some fans that it's lead to a lot of artwork flooding deviantART galleries and some pretty odd Fan Fiction.
And in Malefor's case, it's gone out to being as bad as to make him be not evil at all, but merely under the influence of some other monster and that he crushed the eggs to save them. Tell me that isn't a severe case of this trope...
Ever since Skylanders Spyro and Cynder are showing some signs of being this, since whilst they were eventually an Official Couple in the Legend series, their Skylanders counterparts do not appear to show any romantic attachments to each other.
That One Boss: Dear lord, Dawn of the Dragon's Elite Enemies. At least they're optional.
Red the Dragon in A Hero's Tail.
Both battles with Captain Skabb in The Eternal Night.
The extremely infamous Arborick from The Eternal Night.
Definitely YMMV on this one, though - you'll find actual ARGUMENTS on YouTube videos featuring this battle, people who think Arborick is That One Boss vs. people who think he's the easiest boss of the game. Personally, this troper never had any trouble with him.
Pretty much every single boss in The Eternal Night was one of these.
Replacement Scrappy: for quite a few people, the new cast of The Legend of Spyro compared to the cast in the original series, especially Cynder.
For some, Ripto in the older series replacing Gnasty Gnorc as the main Spyro villain.
Ron the Death Eater: Both Cynder and Ember have gotten this treatment by the fandom. A bit more common with Ember, as her one sided crush on Spyro is often used to make her a Clingy Jealous Girl trying to break Spyro and Cynder up or kill Cynder and have Spyro to herself.
