'Monsters' are various creatures that are found within the Frontier or in other worlds/dimensions that have been mentioned in-game. Most 'monsters' are typically found in various areas of the Frontier, while others thrive in areas such as the Otherworld Tower dungeon or the Rabbit Hole. Each 'monster' boast different abilities, behaviors, and loot and some 'monsters' are biome-specific. Not all monsters, however, are considered as 'monsters'. Some of them may be animals, beasts or critters that can be killed by the player, such as the Brown Bear, Deer, and Grey Rabbit.
All listed mobs will be ranked on how difficult they are. The list is organized in alphabetical order.

Monsters are ranked and evaluated by a combination of means, such as difficulty, survival rate, speed, damage and frequency of attacks. There is a total of 8 ranks, beginning from S+ as the highest rank and F as the lowest rank. The ranking of these mobs are focused on breaking up the difficulty as much as possible. These ranks will give players an idea of which mobs should be avoided until they are prepared.Mobs that have (+) after their specific rank are a hybrid of their tier and considered more powerful. As an example, Circus is ranked in the S+ Tier, along with the mob Democan. They are not considered equal, however Democan is too powerful to be in a tier below. To solve this, Circus is given an additional (+) indicator which is shown as Circus (+).
Mobs that are ranked as "S+" are mobs that are considered some of the most difficult mobs that can be found in the game. These mobs are capable of dealing huge amounts of damage to even experienced players. Attacks and mechanics are sometimes unpredictable and/or not easy-to-remember. It is best for players to equip themselves with good armor and equipment in order to survive an encounter. These mobs are very difficult to solo by itself/usually requires more than one player.
Mobs that are ranked as "S" are mobs with immense strength that can be found in the game. These mobs are capable of dealing huge amounts of damage to both intermediate, and experienced players. It is best for players to equip themselves with good armor and equipment in order to fend off these mobs. Players are expected to be extremely cautious regarding distance as these mobs can easily obliterate players with specific attacks.
Mobs that are ranked as "A" are mobs that are likely to pose some level of threat to all players. These mobs are capable of dealing lots of damage towards the players making them bigger threats if the players fail to react quickly. Dangerous by itself, but even more dangerous when chasing players with other mob’s. Dodging attacks may prove to be quite difficult without the right equipment to counteract it.
Mobs that are ranked as "B" are mobs that have the potential to pose a great threat to players. These mobs may be better when it comes to damage and speed, so players who are poorly-equipped may be at a great disadvantage when encountering it. Typically lethargic in nature but deadly at the same time being tanky, and/or could have unique attacks that may throw players off-guard.
Mobs that are ranked as "C" are mobs that have the potential to pose difficulty to a player. These mobs may be better when it comes to damage, so players who are poorly-equipped may be at a disadvantage when encountering/attacking it.The Mobs moves however are predictable and can be counteracted through quick thinking.
Mobs that are ranked as "D" are mobs that have the potential to harm a player. These mobs are able to damage the player quickly, so players who are poorly-equipped may be at a disadvantage when encountering/attacking it. They are typically underestimated by inexperienced players and can throw them off-guard. A few of their attacks are capable of inflicting moderate damage over time or otherwise hindering their abilities to attack. They pose a threat regardless of whether or not they are found in groups or by themselves.
Mobs that are ranked as "E" are mobs that have the potential to pose a threat to poorly equipped players. These mobs may be better when it comes to damage, so players who are poorly-equipped may be at a disadvantage when encountering/attacking it. They pose more of a threat compared to the mobs listed under F-tier, but are weaker to more dangerous mobs above it. They deal enough damage that could take down inexperienced players quickly. They are dangerous in groups but are weak by themselves.
Mobs that are ranked as "F" are mobs that can easily be killed by players, They do not pose much of a threat as they are unable to inflict a large amount of damage upon the players. Their attacks can easily be dodged/counteracted by the majority of players who encounter them.Some of them are passive in nature or are incapable of harming (cannot attack the players).
Passive - Mobs that are considered to be passive/docile. In the presence of a nearby player, they will attempt to run away from the players rather than attacking them on sight. (fleeing)
Neutral - Mobs that are considered to be neutral. In the presence of a nearby player, they will not attack the player unless they were to be provoked by an attack from a player.
Instinctive - Mobs that are considered to be neutral and instinctive. In other words, if the mob senses a nearby player, this results in the cautious behavior of the mob where it will begin to attack the players as their instincts tell them that they are possibly being threatened by the players or the players is a dangerous threat that needs to be killed. Examples include the Apple Bat and the Pygmy Dragon.
Hostile - Mobs that are considered to be hostile. In the presence of a nearby player, they will attack the player on sight whether they had been provoked or not.
Avoidant - Mobs that are considered to be hostile and avoidant. In other words, the mob will attack the player if they are close enough within their aggro range, however, if the player approaches it, they will make an attempt to distance themselves to continue their attacks. An example being the Dull Frog.
This list will show you the mobs, creatures, entities, and people that are mentioned or seen in-game but do not have any direct information about its existence on the Frontier. They are typically mentioned by other item's descriptions, although it is unclear if these mobs will be implemented in-game.
The first mob that is technically identified by the players upon reading the tutorial. It is considered as the "Beta Ogre" as this mob is seen in the Tutorial ever since the release of Fantastic Frontier. It is unclear whether or not this mob was an old design of a pre-existing mob or a mob that never got to be implemented.
Upon further questionings, the developers confirmed that it was a potential color palette of a Blue Ogre, but was later made so that the Blue Ogre were passive and hence, it was never included in-game. This would've meant that the Blue Ogre was initially hostile before being changed to have a passive behavior.
A statue of an unidentified creature that can be found in Ancient Forest. It is unclear if this is supposedly an old design of the Ratdog or an actual Ratdog.
The developers confirmed that it was a dog that they once had before it passed away.
Mentioned from the Romo armor set's descriptions, the Romo is implied to be an invader of the Frontier from another world.
Von Jerry the Giant
Mentioned by the Von Jerry's Hat of Illusion, it was described to be a profaned funny-man, as well as being a type of giant. The word profaned means to treat someone with disrespect and it is assumed that Von Jerry was not something or someone that was 'easy' on the inhabitants of the Frontier and enjoys making comedy out of awful situations.
This list will show you the four mobs that do not appear in-game nor do they have any information about its existence. These four mobs appeared on the Monster Index when the page was being made and edited.
Edit: A long time ago when the wiki was still developed, a former content moderator known as RoseyNosey on the FF's Discord server provided all, if not, most of the names for the older 'normal' mobs of the Frontier. Some mobs' names had gradually changed and renamed over time while others still maintain their very 'ancient' nickname. Four of the mobs below and listed are unidentified mobs and supposedly come from the two unidentified beasts seen in the List of Easter Eggs.
