** The same can be said for the third boss in HTFA 5, as well as Fire Koopa in HTFA 6.

** In HTFA GB, [[VideoGame/MegaManV Hyoey]] appears as a boss in the penultimate level. Damaging it is pretty easy, but its [[SpreadShot shots]] are so fast that it's just useless to try to dodge whenever they're fired. You have to get the timing down in order to keep your character safe, but even then the timing might be screwed often because the boss keeps switching places (and no, it's useless to stand behind it when it's moving, it's programmed to always face your character), forcing you to do the same as well. Also, keep in mind that even if you've finally gotten the timing down very well, you can only make '''five''' blunders (either from the shots or from CollisionDamage).

* BreatherBoss:

* GrowingTheBeard: As more sequels and spinoffs are made, the series keeps getting better, both graphically and "game mechanic"-wise. Sprites are rarely re-scaled to the point of looking ugly in the more recent games and game physics keep improving with each game.

** In HTF Origins, [[spoiler:we have the Flame Dragon's flame attacks. Among the usual red hot flames, there are bigger, blue flames that take off two health points from your character if he/she gets hit by those. Combine this with the somewhat poor MercyInvincibility, and you'll die often. It seems as if the extra life placed on the boss room is there to cover up the difficulty.]]

** In HTF Origins, it's either [[spoiler:Flame Dragon]], Bowser himself, or both. You're going to hate flames in this game, especially the blue ones, a lot more than flames from other games.

** In HTFA 5, for a boss in the penultimate kingdom, Wart is incredibly easy to dispatch.

* BrokenBase: Boy, where do we even begin? Most of the casual HTF fans enjoy the series, especially considering that HTF fangames aren't really commonplace and this is one of the most decent ones. Crossover fans even more so, due to the series' nature. The more serious fans usually shake their head at the ridiculous concept, but other parts of the fanbase outright hate it for many reasons (CharacterDerailment, {{CrossOver}}/MegaCrossOver, inclusion of [[OriginalCharacter fan characters]], etc.). Non-HTF fans, especially fans of the video games featured in the series, either accept it as SoOkayItsAverage, facepalm at the concept, end up being simply confused at what the series is trying to do, or hate it with a passion.

* MostAnnoyingSound: HTFA 4 introduced playable character voices, which can only heard whenever he/she jumps, gains an extra life, or dies. Starting from HTFA 6, the playable characters now make noises when shooting. Many players may prefer to shoot at all times, so the poor player has to deal with the grating voices.

** In HTF Origins, it's either [[spoiler:Flame Dragon]], Bowser himself, or both. You're going to hate flames in this game, especially the blue ones, a lot more than other games utilizing these.

** In HTF Origins, [[spoiler:the final boss can be considered this.]] (see ThatOneAttack section for why)

* HilariousInHindsight: The HTFA series' playable cast usually consists of Cuddles, Flaky, Petunia, Nutty, Giggles and Toothy. [[spoiler:Flippy also appears in this series, but he's not playable, only appearing as a boss in two main games and as a NPC in one spinoff]]. An official HTF iOS game called ''Deadeye Derby'' has exactly those characters as the standard playable characters. [[spoiler:Not only that, you can fight Flippy in the latter game as well!]]

** HTFA 4 introduces a skiing section, which in this game is located in the fourth level. Prior to this section, you platform your way while avoiding the water-based Blarggs that pops out from the water. If your character's not a high jumper, you'll be more likely to get hit. But other than that, this is considered a breeze compared to the skiing section itself. There, you're carried by Neena as you try to either dodge or shoot the many enemies that appear. The problem lies in the second part of this section. There are some parts of the level that require you to jump over lava pools. The fact that there's lava in a ''water''-skiing level is bad enough, but you have to have a near-perfect timing if you don't want to end up falling into those pools. Also, due to being an AutoscrollingLevel, get ready to get squished often. However, after this part, you're going to face [[ThatOneBoss Ludwig]]...

** In the first HTFA, [[spoiler:Giga Bowser (which doesn't resemble his [[VideoGame/SuperSmashBros SSB self]])]]. When you start his level, there are several health items and an extra life at the bottom part. Then you start climbing up. You'll die a lot to his fireballs when you get to the upper platforms. Remember, the MercyInvincibility mechanic in this game is very poor. What makes this worse is that the fireball graphics are located underneath the boss's layer, so you cannot see them easily before it's too late. [[labelnote:Hint]]Watch the pattern of where the fireballs are coming. Seeing that each fireball is fired at you in a straight line, you can see where this is going (if you see a fireball being shot above you after you jumped, prepare for another jumping as the next one is aimed to the ground).[[/labelnote]] This is pretty much a SurpriseDifficulty in this game when it comes to bosses. [[spoiler:He's the final boss, after all]].

** In HTFA Land, you have Crush Crawfish as the boss of the third world. Its attacks are actually easy to dodge. What's the problem? ''The water''. In a certain interval, a large amount of water rises, forcing your character to swim while still dealing with Crush Crawfish's attacks. This can lead to awkward controls, especially when the water drains back after a certain time has passed. If you pick Toothy, the battle against this boss, while still a bit difficult due to the swimming physics, will be more doable. If you pick someone else? Prepare to struggle a lot.

* SoBadItsGood: Another result of the above Narm factors.

** In HTFA 6, [[spoiler:Mecha Tacho]] is this. Like [[spoiler:Flippy]] and [[spoiler:Mecha Neena]], this particular boss follows you. Despite only walking along the ground like the aforementioned two bosses, he presents more difficulty than those two. First things first, he mainly attacks by shooting fireballs, which are fast. Secondly, he can also fire missiles in (somewhat) random intervals. Thirdly, and the most important factor to the difficulty he caused, is the boss room layout. Both of the two bosses mentioned above have a friendly layout that simply consists of two small platforms on one side each, aside from the flat ground both you and the boss can stand on. They're placed low enough, but are convenient enough for moving from one side to another without [[CollisionDamage colliding with the boss]]. In this boss's case, however, the layout consists of a single floating platform placed high, which can only be reached via either one of the two moving platforms on each side, which move up and down. Using those platforms, in fact, lessens your chance of hitting the boss because, remember, the boss actively follows you and forces you to keep moving. Now, combine that with the boss's attacks, and you have a recipe for frustration.

* Narm: The broken English and cheesy plot pretty much result in this. Also, the whole crossover idea.

** In HTFA 5, pretty much any "huge flame"-based attacks from the three (out of seven, not counting Birdo) bosses can be this. The flames cover quite a long range, about half of the screen. The worst part is that, the flames follow your character, so it's near-impossible for you to avoid them unless you're out of range. The third boss in this game is the worst offender, as it constantly moves from side to side, and it's pretty big too, so you have to force yourself to jump over him every time with the help of the floating blocks, making the flames even more likely to hit you.
