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.
Chaotic Good: As mentioned in Anti-Hero above, Toriko isn't really strictly a "good" guy. He, Sunny, and Coco are all pretty much Chaotic Good because, while they do pretty much whatever they want, they are inclined to do good things/help people, rather than screw others over(Sani pushes this though given his narcissism).
Zebra on the other hand is DEFINITELY Chaotic Neutral, if not Chaotic Evil. He will do anything he wants and damn the consequences if it doesn't go against his own (very selective) personal rules (which boil down to 1. don't be cocky, 2. don't EVER lie.) Or the rules of people he likes, I.E. Toriko and Komatsu, Toriko BARELY given (he just wants to fight Toriko).
Complete Monster: The Gourmet Corp. in general, Starjun might get away with being a Noble Demon based on him not attacking those who are not in his way but it's a little early yet to say for certain.
Ensemble Darkhorse: The first character poll put Uumen Umeda in 8th place over more prominent characters like Tommyrod, Melk, Rin, Setsuno, Jiro, Mansam, and Zonge. You could count the number of Umeda's appearances on one hand.
And now it looks like Uumen is actually a member of NEO, who seeks to destroy the IGO and Gourmet Corp. - and may be much, MUCH stronger than he initially let on.
Fridge Brilliance: The reason why Toriko spent so much time trying out the exhibits at Life, the country of healing seemed to be so much different than his normal curiosity, was because it was different. Toriko is afraid that there won't be a cure to regrow his arm, and he is fooling himself into thinking about other stuff to take his mind off of it as most of us do. The exhibits aren't food, the only thing that actually gets Toriko excited, so it makes sense.
Ho Yay: Lots of it, to the point of TorikoXKomatsu being practically canon by now. Komatsu's interaction with the Second Melk did somewhat counteract it, though.
Toriko: Komatsu, how about you and me form a "combo"?
Coco becomes very concerned for Komatsu in episode 4 and 5, after Komatsu becomes friendly with him even though Coco is poisonous.
Not to mention the last page of Gourmet 34:
Komatsu: Did you do something to me!?
Sunny: I diiidn't. Do you want me to do something?
This after he pretty much fawned over Komatsu's cooking skills, saying he's beautiful when he works...
Toriko compares being "tasted" by Sunny's hair sensors as being licked by him. In the show, this is demonstrated by a shot of Sunny literally licking Toriko's cheek. Sunny's descriptions of people's actions/emotions towards things as "beautiful" doesn't help — Komatsu's cooking, Coco's entrance...
When they are traveling on the Gourmet Carriage, some classical music starts playing and Sunny grabs Komatsu for a dance. Then you see Toriko and Coco waltzing together, looking like they have no idea how they got there.
The fact that Toriko, Sunny and Zebra are all fighting over having Komatsu as their "partner" makes it feel like a really strange harem anime.
HSQ: The introduction of Head Waiter Alfaro. Two horrific behemoths, the ruler of Ice Hell and a mutated insect, each with capture levels in the high 70's are duking it out in the sky. Alfaro slices them to pieces in a second. With dinner plates.
Promptly one-upped by Setsuno. Alfaro is about to pull out his dinner plates and kill her while her back is turned, but never really gets the chance seeing as Setsuno broke the plates from several yards away using what we can assume to be the aura of 'screw you' she was emitting.
Master Chin takes it up to more ludicrous levels. His secret food technique, "Spoon", can literally carve out mountains. He did this once before...at "Death Falls", before we even knew it was him.
Toriko vs Starjun, Coco vs Grinpatch, Sunny vs Tommyrod...and...Setsuno vs Chiyo for the latest arc. On top of a mysterious third faction and the Bishokukai actually having captured and weaponized a Nitro which pwns Yuda with ease!
Down in the basement of the stadium where the fighting at the Cooking Fest is taking place, it seems as though Kuriboh, Kousairou and even COOKING KING ZAUS HIMSELF are all planning to either capture or kill Setsuno. They're working together with the richest men on the planet, such as the King of Jidar and President Mohs.
Memetic Molester: Livebearer seems to be approaching this status, thanks to his... off appearance and suggestive dialogue towards Komatsu (although to be fair, it was moreso to eat his brain).
Nausea Fuel: If this manga in general is full of Food Porn, observed dietary preferences of Gourmet Corp. serve as Fetish Retardant to it. For members of what their Japanese name translates as "Beautiful Food Orginization", they sure are prone to eating disgusting things in disturbing ways.
One such example would be Grinpatch who taunts Toriko by not only stealing and eating all of his BB Corn, but proceeds to vomit it back up and eat it again!
Nightmare Fuel: Tommyrod. Good God, what a monster The man is a walking insect nest, who can do some downright disgusting things with his bugs. And don't get started with his rows of razor sharp fangs
Grinpatch. Insect-emulating mutated abomination, with a taste for others' despair. And he means it literally. Only fails to be the most disgusting and nightmarish character in this manga due to being completely overshadowed by Tommyrod.
Zebra can make it sound like he's standing right behind you even when he's tens of kilometers away.
When the ancient Nitro first appears behind Komatsu. Nitros in general, being the inspiration for the GT Robots.
Losing a bet in the Underground VIP Area of Gourmet Casino means you will forget the taste of every food you have ever eaten.
The huge monster that represents the Four Beasts in the legends describing them is terrifying. The image of countless humans writhing in its jaws...
The ending to Chapter 208. Oh God, the ending. Mood Whiplash at its finest. Anymore would spoil. Turns out to be just a nightmare.
The Pierced Nitro in 222 and 223...
The Giant Parasite in 224. To quote Sunny: "GROOOOOOOOOAAAAAAAASSSSSSSS!!!!"
Needs More Love: While being successful domestically (it's even viewed as Japan's replacement for Bleach), the series hasn't been getting nearly the attention it deserves outside Japan.
The Scrappy: Tina the news reporter seems to be this for fans of the manga, as she is put into a lot of arcs to add as a Ms. Exposition. Fans who were introduced to the anime don't seem to hate her as much.
One of the reasons given is that those fans see Toriko as a male buddy story/more reflective of old school shonen manga. The addition of Tina supposedly removes some of the testosterone fueled awesomeness so that there can be a relatable female character to bring in female fans as it is "considered wrong to have series nowadays solely aimed at males".
Rin can also be seen as this. Her gushing over Toriko can get annoying, and for a while, most of the time her fragrances don't do anything.
