Tyrathius: The Kirby characters were a bit of a Spotlight-Stealing Squad for pretty much the entire game, but there's one moment in particular I thought was really stupid: The beginning of the game. The stadium is attacked by primids, but they are easily defeated by Mario, Kirby, Peach and Zelda. But then Petey Piranha shows up, and somehow manages to One-Hit KO Mario, a character who has defeated him with ease numerous times in his own series. Petey then proceeds to capture Zelda and Peach without a fight, even though both of them are capable fighters in their own right. Yeah, a minor boss is able to defeat three of Nintendo's biggest name characters, for seemingly no reason other than to force you to do the subsequent boss fight using Kirby. Not only is that a bad idea from a gameplay perspective (what if the player just isn't any good with Kirby?) it makes Kirby seem like an unbeatable Mary Sue who trounces threats the other characters can't handle with ease. Even if they wanted the Princesses captured as a nod to their Distressed Damsel roles in their main series, there was no reason to get rid of Mario.
ilovedededeAGAIN: The worst scene in this game is when Luigi gets turned into a trophy. King Dedede, my trademark favorite character in video games (hence my username) turns Luigi into a trophy. Wario then comes along (with trophies of Ness and Peach or Zelda) in his vehicle and plans on taking the Luigi trophy. But then guess what happens: a squad of Waddle Dees come and attack Wario (WTH?) and King Dedede manages to steal Wario's vehicle. King Dedede may be a video game villain, but he's not THAT bad for a villain (compared to Bowser or Ganondorf), so there was no reason the writers of the Subspace Emissary cutscenes had to turn him into a car robber (at least he gets better close to the ending). The worst part, though, is that Wario never gets his car back. The whole plot of the Subspace Emissary would probably change dramatically if King Dedede stole Bowser's car (yes, he has one too) instead, because back in an earlier level he turned Donkey Kong into a trophy. It would actually be better than stealing Wario's car, since Wario looks like a weak fighter, compared to Dedede himself and his horde of Waddle Dees (don't forget his hammer). Wow, Sakurai. You really did it this time.
ShiningwingX: It gets even worse as the game goes on but the biggest kicker for me has to be toward the end. After all the characters are turned into trophies by Tabuu's Death Ray attack, who among them turn out to be the ones to save them all, and without whom the bad guys would have won? Kirby, and King Dedede. Somehow, Dedede had more insight into what was really going on than any other character and PLANNED for this with the revival badges. Up until this point Bowser and Ganondorf are known to have much more internal knowledge and involvement in the plot, especially with the scenes showing Ganondorf frequently speaking to Master Hand himself (who, we discover is being manipulated by Tabuu. Throughout the course of the story Dedede is shown to be just above Wario when it comes to being in the know so how in the WORLD could he have figured things out so easily when even Ganondorf was unable to? Its never explained but for an extremely vague explanation by Nintendo on the game's website, which mostly boiled down to "He just knew". As for Kirby, how does he manage to wake up and save the day after being blasted by Tabuu along with everyone else? He just eats the revival badge.
genericity The Showdown in Melee was a good final event because the characters you were fighting were thought of as evil and Mewtwo and Ganondorf play together excellently and Giga Bowser alone is a force of nature. What was Brawl's answer to this? A fight against Sonic, Snake and a giant Mario. The event is easy, the characters have no connection to each other and the AI is unexceptional. It just seems like a way for Sakurai to glorify Sonic and Snake's presence. And to add insult to injury there is a pathetically easy event where you fight Ganondorf, Dedede and Bowser together.
Cookieman: Oh I thought this event was extremely anti-climactic as well. The point of the event was to illustrate the three companies: Nintendo, Sega, and Konami. Nintendo was considered the "big" company so Mario was big. I thought it was a stupid event too. I also hate the two-player version where you fight the villains and anti-heroes. I do however think the very last event of the Two-Player mode is a fun one (Fighting off every single character).
Trialman: Super Smash Bros. For Wii U continues with the Disappointing Last Level problem in Event Mode. This game's last event is that the player goes against Mario, Mega Man, Sonic, and Pac-Man. Practically the exact same premise, but for this one, they don't even use Final Destination, but Battlefield, which makes avoiding the opponents much easier. To make it worse, you only fight two of them at one time, ruining the whole premise of fighting all the main mascots in a team. Again, it feels like a glorification of the third-party characters. Especially disappointing considering all the criticisms that were addressed in this game.
IthoughtyouwereLuigi The thing that I really hated about the story in Brawl was how confusing it was, the only time I could get what was going on was at the beginning. It especially got confusing by the end where none of the previously established villains were even the main villain,not even Master Hand was the main villain!Instead we get Tabuu, who not only makes no sense, but also broke the already well established "just a kid playing with his toys" theme, and that is what ultimately made me mad.
Cookieman: Subspace related, but something that really bothers me to this day is when Pit/Mario and Yoshi/Link join teams? When Mario/Link sees the other team defeat the opposing princess, they attack them ... not too bad, but why the heck would Mario and Yoshi not acknowledge each other and probably explain that it's a misunderstanding. At least there's a scene later on in the game where Mario actually rides on Yoshi.
King Clark: One thing that I don't like about the Wii U version is that there wasn't nearly as much effort placed into the Palutena's Guidance conversations as there was for the Snake Codecs (such as one being entirely dedicated to Wario's flatulence), but the absolute worst of them has to be the one for Robin. In it, Chrom makes a cameo, only to be mocked relentlessly for no reason - I'm not even a fan of Fire Emblem, and this pissed me off (most likely because this felt like a thinly-veiled and mean-spirited jab at the fans that wanted him to be playable). The cherry on top has to be Viridi's comment that Chrom would effectively be a carbon-copy of Ike and that Moveset Clones are effectively pointless, which completely fails as a joke for two reasons. The first is considering that the roster already had three complete clones on the roster, one of which was a different Fire Emblem character, and another of which was a Kid Icarus character - they tried to go for Hypocritical Humor, but the joke falls flat on its face since they failed to allude to the actual hypocrisy of the inclusion of either Lucina or fucking Dark Pit. The second reason that this makes no goddamn sense is that Sakurai and company were able to make viable movesets for characters like the Wii Fit Trainer, the Animal Crossing Villager, and the Duck Hunt Dog/Duck/Gunner, but evidently going by this conversation, adding another sword-wielder was apparently too daunting a task for the development team to take. What a waste of an Easter Egg.
BlueSunStudios: Ditto on this entry. I really do try to give Sakurai Masahiro a breath of fresh air instead of falling into the Accentuate the Negative trap that most of this fanbase has fallen into, but this conversation is not helping him at all. Sakurai himself said in an interview that Chrom himself would not bring anything new to Super Smash Bros. since his role is fulfilled by Marth and Ike (i.e. he is a blue haired swordsman, as if that's the only thing to him) yet Lucina getting in completely contradicts and invalidates Sakurai's reasoning for excluding Chrom. To make things worse is that Lucina's case of being a Marth carbon copy is also excused and justified in-game when in-universe (Fire Emblem speaking) she has little-to-no logical reason for being one.
JustDancerStarships: My least favorite Palutena's Guidance is the one on Ness. When Pit is told of Ness's PSI, Pit, in shock, calls it unscientific. Pit, your entire world alone is based on Greek and Roman mythology, your bow fires arrows of light, you use telepathy, the list goes on too long! Ness is more scientific than you could ever be! Also, Palutena tells Pit what he just said was stupid, but pointing out your problems does not make them go away!
JustHereToComment: This also feels like it's trying to copy the Snake Codec where Snake feels that magic is unrealistic and Mei Ling replies that the technology they use could be considered a kind of magic. However, unlike that one, Pit dismissing the idea of magic is really hard to swallow since Pit is essentially a fantasy character who uses many powers that can only be considered magic, unlike Snake, who exists in a mostly realistic environment. Perhaps it could've worked if Palutena had explained Ness' powers scientifically and Pit complained that she was ruining the magic for him. Instead, it comes off as a poorly-constructed attempt atHypocritical Humor.
Skapokon: OK, call me a nitpicky guy, but it really annoys me when Trophy Descriptions in Smash get things wrong, specially the origin games of the characters. From minor mistakes such as saying that Meta Knight comes from Kirby Super Star instead of Kirby's Adventure to huge mistakes such as how the main Mario cast in Paper form debuted in Super Paper Mario according to Brawl, ignoring the 2 games that came before it. But the biggest blunder and the D Mo S for me is how Rayman (and his friend Globox) debuted in Rayman Origins. That's right, they completely ignored the entire Rayman franchise just so they can promote both Rayman Origins and Legends via the trophies. And even that doesn't make sense because Rayman 1 and 2 are on the 3DS (the former via DSiWare, the later via the port Rayman 3D), which makes me wonder if they made this mistake on purpose or whoever was in charge of the trophies legitimately thought that Rayman and Globox debuted in Origins.
