Derous (デロウス Derousu) is a powerful species of dragon from the world's distant past. It was said to be the strongest dragon to have ever lived, using the power of its single, mighty fang to rule the world. The Derous is thought to have lived for 10,000 years. True to its status as an ancient ruler, a Derous is one of the mighty Eight Kings, the eight most powerful species in the world, which ruled Area 1 of Gourmet World.


The Derous is a gigantic dark brownish-green dragon beast with a body length of 4000 meters, and an incredibly titanic body weight of 80,000,000 tons, with it being significantly heavier than a Regal Mammoth (one of the largest creatures in the Human World alongside the Magma Tortoise) which only weighs around 55,000 tons; however, the Derous that became one of the Eight Kings is so big it can grasp a mountain in its palm. Like most dragons, the Derous is reptilian in nature and possesses a leathery hide, a pair of very large wings on its back, and a long reptilian tail. It has five pairs of slitted eyeballs. The Derous has a pair of very muscular arms and legs; its "hands" have four digits with sharp claws and its feet have three digits with sharp claws as well. The sides of its neck and the top of its head have sharp rows of spikes over them, its wings also sport spikes along their leading edges. Its most notable trait lies in its mouth which is completely devoid of teeth except for its one enormous tusk-like fang which is of incredible durability and its bottom lip is parted in a certain way for its massive tooth to fit. Also of note is that it has a large number of tendril-like tongues.

The Derous is a ferocious and powerful creature that appears to be very territorial and will attack anyone that enters its domain. Those who enter its territory are those who seek the rejuvenating Cure Water, however the exact relation between the Derous and the Cure Water remains unknown.

Like all the Eight Kings, the Derous has a keen awareness and can detect even the slightest change on the planet, and it also helps to preserve the natural balance of the domain it rules over.

It is unknown how many members of this species there are or how it reproduces as it is usually referred to as a single entity (likely the single Derous being the member of the Eight Kings). Whether this implies that Derous rarely breed or that there is only one Derous left remains unknown.

Powers and Abilities[]

Deorus intimidation anime

Even a small piece of the Derous' fang can create a powerful intimidation.

Being one of the Eight Kings the Derous is one of the most powerful creatures in the world and its ancestor was once the most powerful being in the world and ruled the planet for 10,000 years. All of this clearly indicates its abilities are incredibly powerful but unknown to what extent.

A lone Derous has come to be known as one of the Eight Kings, and at one point in history, the ancestor of this species was said to have ruled the entire world. Besides possessing immense strength, what truly set them apart from most other Gourmet World beast, is said to be their "sensitivity", which allows them to sense potential dangers, and has helped them survive mass extinctions. To this day, a Derous continues to rule over the entirety of its Area in Gourmet World.

The single fang of the Derous also holds powerful regenerative properties, and if the fang is made into a blade, it can function as a Revitalizing Kitchen Knife which can instantly heal and regenerate damaged or lost tissue. Whether this implies that the Derous has regenerative abilities or if its fang simply has these unique properties within itself only remains uncertain.


Derous Laser

Extra-Dimensional Laser (異次元レーザー Ijigen Rēzā): From each of its tongues, Derous fires beams of energy, which pool into a single ray of Gourmet Energy. This beam is fast enough that Acacia is not able to bring out Neo to consume it, and is strong enough to travel outside the planet into space and to retain enough destructive force to tear apart several planets and other objects in space that are in its path.[1] This laser when fully charged is strong enough to kill even Whale King Moon whose capture level is higher by 10 than the capture level of Dragon King's.



At an unknown point in history, a mighty Derous once ruled the entire world with its tremendous power. Its reign lasted for over 10,000 years. The remains of this powerful beast would eventually become fossilized underground in an unknown location.

Gourmet War[]

After Acacia and Froese returned from doing their efforts to stop the war, the Chef Goddess had become horribly weakened from cooking GOD. Midora went on the search for Cure Water to relieve his mother, despite her objections. Unfortunately, the miraculous water was protected by an offspring of the Derous, and this left the young tiger in a severe condition after fighting the beast, although it is unknown if the dragon survived. He was successful in getting a portion of the water and returned to his home to give it to Froese.

Melk Stardust Arc[]

Derous's fang

Derous's fang

At some point in the past, Melk the First excavated part of a fang from the fossilized body of the ancient Derous who once ruled the world. Due to the fang's incredibly durability, it was extremely difficult to process without Melk Stardust. A piece of the fang is used to make Komatsu's knife.

Appearances in Other Media[]

Toriko: Bakushoku Gourmet Battle[]

The Derous appears in Toriko: Bakushoku Gourmet Battle as a special card in the game. Its card's statistics classify it as a "Power" class beast. It has a high power of 9187 and an incredibly high defense of 36750. It also has a subspecies known as the Shadow Dragon Derous (暗黒竜デロウス Ankoku Ryū Derousu) which has a darker color scheme.


  • In Volume 29.5, the Derous is said to be the ruler of Area 4; however, in Chapter 325 the Mother Snake is said to be the ruler of Area 4. It is likely that this was simply an error in the volume or a retcon.
