Symbols of IMa and FIMBA respectively.

In the Monster Rancher/Farm game series, both FIMBA and IMA are national monster battle associations for registered breeders. The latter is younger than the former, and is known for its system for hunting stray menacing monsters as bounties. Both organizations are considerably influential in the breeding system among the game series; along with the new AGIMA group, they formed the Elives School of MR4.

Information here most regard what's seen in the Howl of Gray Wolf and Tiger of Freedom fictions.


The fanfiction take place on a planet with two continents and an archipelago. Long ago, it was just a single continent called Pangaea (πανΓαῖα, Greek for "universal Earth"; パンガイア; 全て大地)[1] and both Monsters and Humans coexisted as the top lifeforms. When humans wanted to discover a way to mimic a monster's magical abilities, they built the urban city of Panpólē (πανπόλη; Greek for "universal city") and invented their own monsters through technology. The dragon superbreed Moo was genetically engineered in Panpole and he was so consumed by his power, he turned on the human race and imposed a war on them. This was called "Ancient Monster War". The violence had spread worldwide and broke Pangaea in two and a cluster of islands. Many centuries later, the Monster Breed associations, IMA and FIMBA, were established on each continent. Years after the War are labeled as "After Pangaea" or "AP" (ie: 803 AP). More from Liber Genesis.
(πανπόλη) The former capital of Pangaea, and its first and largest urban city. Panpólē was known as the "Ultimate Capital" because it held the largest population of humans. It was also where the limits of technology were tested through bio and mechanical engineering. Creatures such as Henger and Moo were formed.
About Monsters
Monsters are natural creatures like humans. Many monsters like Tiger, Dino, Hare, Mew, Moochi, Jell, Gaboo, Mogi, Hopper and Pixie are common. Large monsters like Baku, Golem, and Psiroller are a little more rare. Rarity also depends on a monster's bad, strange, or reclusive nature (ie: Naga, Niton, Beacolon, Undine, Gitan, Zilla, Centuar), if it exclusively reside in a specific region (Durahan, Lesione, Colorpandora, Undine, Dragon, and Bajarl), or if it must go through a unique evolution in their life cycle (ie: Beaclon). Monsters can be exported to country polar from origin, due to the links between the associations FIMBA and IMa (ie: Zuum and Dino), or they move there (ie: Zilla). Some of the rarest monsters such as Gali, Suzurin, Ghost, Monol, Magic and Phoenix were considered Divine and sometimes worshiped as Gods. The Ghost monsters are symbols of good luck because they are the souls of dead monsters who enjoyed a good life with their friends. In relation to Divine types, the strongest are capable of forming their own monsters. There are also evil entities like Joker; similar dark entities resembling Gali and Magic (the monster) can be found. To conclude, monsters can be genetically (ie: Superbreeds) or mechanically (ie: Hengar, sub-types relating to it, Zan) engineered. Also, it's rumored that monsters can come from outer space (ie: Metalner).
Chimeía Tribe / Islanders
(χημεία φυλή; chimeía phūlē; Chemistry Race) Very few humans are known to have an attachment to something akin to sorcery, spiritualism, and alchemy. Thus, such power was conveyed and pursued through science. On the chain of islands outside of the continents exist a tribe with "divine abilities". The majority of them are breeders and prefer to use their abilities to protect nature and form a friendly bond with monsters, while others still try out clandestine experiments with transformations, immortality, etc. The term Chimeia is used exclusively by the people of FIMBA and IMa, who assume that the tribe gained their powers because of their attachment with monsters caused their molecules to alter into theirs. In the video game series, they are probably similar to the Tochika (トチカ人; tochikajin), who advised the world of monster breeding, battle, and monster regeneration.
Dragon Forces / Dragon Four Generals
The initial problem in Howl of Gray Wolf fiction. Around the world, four dragons advocate a paradise for monsters by gathering both nigrum (see below), and allies who are willing to support their cause. Their methods are deemed radical at best. The forces are led by Jesvah, Ragnoroks, Techno Dragon, and Diabolos.


Developed by humans long after the Ancient War, a shrine is a small building that contains a machine built to “unlock” Disk Stones using solar energy. They are also considered as ruins (廃虚), past relics.
Disk Stone
The saucer-shape piece of rock that holds the form of a monster before they are born and when they die. The colors of the stone vary depending on the monster inside; only monsters can sense the same breed inside a stone. For example, Tigers can sense Tiger Stones. In Japanese, it is called Enbanishi (円盤石; disk stone).
Lost Disk Stones
Also called "Dead Disks". A Lost Disk Stone is known as a monster's "corpse". Their innate magical ability makes them become a saucer-like form called "CDs" when they die, which also gives them the advantage to be resurrected later after a long amount of time has passed. The disk becomes fossils. The disk stone are saturated with life after a long rest and the only way to revive them is by "unlocking them". The monster will be the same species, but will have no attacks or memories of old life.
Latin for "black" (neuter adj). This word is used to represent the natura or nature of the Monster World. A forbidden and fearful arcane energy said to be attached to negative emotions, immorality, evil, etc.
Derives from the word lūx, lūmen, lūce, meaning light. The opposite of Nigrum. An arcane ability that is often attached to light and positive energies. Related to healing abilities; also called album, meaning "light".
Nātūra / Natura
Latin for "nature". Refers to the inborn abilities pertaining to a monster's nature. This is to separate them from nigrum and luci.
Purebreed (PB) & Superbreed (SB)
While a PB monster true to its type without being mixed with another, a SB is a monster with an unknown mix. However, it's abilities are beyond normal than its main breed. Examples of Super breeds are Gray Wolf, Moo, White Mocchi and Sniper.
Ancient Monster War
War between Moo and the Human race centuries ago, which caused Pangaea to break into two continents and islands. Similar to the anime story (古代人の戦争; War of the Ancients).
(マブダチ) Called "Soulmates" in Monster Rancher Advence 2. The term is a compound word from tomodachi (友達; true friends; best friends) and possibly "mabui" (瞼; eyelid, memory) because it means "a friend of the heart". Linking with different other monsters, especially breeder monsters with wild monsters, an ability is gained.

The Baddies symbol from anime has same role in fanfic series.

Also called "Crest or "Badge". Based on the Baddie/warumon (bad monster) crest in the Monster Rancher anime. A round-shaped item that identifies monsters that serve Moo and the Dragon Four. They are closely attached to the nigrum of a spirit, and reinforces it to monopolize the wearer. There are five types:
  • Moo Medallion: Worn by the Dragon Four Generals, who serve the first Superbreed. It is the shape of a dragon's head.
  • Dragon Medallion: Worn by the subordinates of the the Dragon Four Generals (Jesvah , Diabolos, Ragnoroks, Techno Dragon). Each symbol looks like a dragon with a different color, depending on who the wearer serves. Jesvah is red, Ragnoroks is black, Diabolos is white, and Techno is tan.
Rhodo Mithri
Fictional plant; etymology is a combo of mithridatium and rhododendron. The latter is known to contain deadly fluids.
Ancient Stone
A gigantic disk stone filled with power was broken during the pre-AP era. Its fragments were scattered all over the world.
Enhancement Drugs
Larox, Manseitan, Troron, Paradoxine, Nageel, Kasseitan, Teromeann


The Continents and Islands
After the Ancient War, Pangea was split into two bordered continents and a chain of islands. The continents remained unofficially named, designated by their location, but are sometimes defined by their monster association. For example, Eastern Continent is called the FIMBA continent and the Western Continent is called the IMa Continent.

Monster Breeder Organizations

FIMBA (East)

It is derived from the national monster battle association (モンスターバトル協会) of the same name introduced in the game Monster Rancher 1.

Another guess is Federation Internationale de Monster Battle Association, similar to FIFA (Federation Internationale de Football Assocuation).

Dragon and Jill have high INT as well but have low guts regeneration.

"E" is the lowest while "S" is the highest, similar to the Official Breeder Tournaments. They also correspond to the numerical monster status (1 - 999) of the video games. Examples below:
