Monster companion

The monster companions are passive, tamable critters in NewWorld Online, which are extremely rare. They first appeared during the second event. Although this event marked their first appearance in-game, they weren't fully accessible to players until the seventh floor was released so that they would become commonly available to everyone.undefined

When a player acquires a monster companion, they gain an item called the [Bridge of Bonds], which is a ring accessory. When the seventh layer was released, the system restricted it so that only a single [Bridge of Bonds] accessory can be equipped at any given time.

Mythical Beast
So far, the are only four existences of Mythical Beast eggs that are seen. They were items that could be acquired during the second event. Extremely powerful bosses guarded the eggs, which were believed to be impossible to defeat, and was out of most of the players' league to fight. There were no given clues that would reveal information on how to hatch the eggs, that even the developers believed it would be physically impossible for players to acquire and hatch the eggs.

The avian boss Silverwing guarded the fox and turtle Mythical Beast eggs before it was defeated by the efforts of Maple and Sally. Maple chose the egg with green colors and hexagon-shaped outlines. Sally took the the remaining egg, which had a faint violent color. In the anime, the fox's egg is purely white, which is wrapped in a shimenawa, which colored white and red.undefined After a period of incubation, both eggs burst open to reveal a monster critter. Maple's egg hatched to reveal a turtle, which she named Syrup. The reason reason why Maple decided to name the monster Syrup is because she thinks she can combine its name with hers, which becomes Maple Syrup.

Sally's egg later hatched into a white fox, with a shimenawa wrapped on its neck. She named the fox critter Oboro. In other sources, Oboro's fox fire is violet, as opposed to his fox fire in the anime which have hot colors, such as orange or yellow.undefined

The primary Sea Emperor, which was not seen in the anime, guarded the bird and wolf Mythical Beast eggs.undefined

Rare Beast
The first rare-tier monster companion seen in the series are the bears that the twins, Mai and Yui, acquired.undefined A player can acquire a bear by finding its lair, which is a cave, and defeating it in combat. In the case for the twins, they followed the bear onto the cave and defeated them with practically no effort, only one attack was enough to finish the bear. This bear monster theoretically had the [Enlarge] skill, which it presumably used before its battle with Mai and Yui.

This bear monster companion probably has a difficulty level for players, but the twins just bulldozed through the fight and acquired the monster companion easily, so it is unspecified how high the actual difficulty is. The bears' names are Tsukimi and Yukimi.

Kasumi acquired a rare-tier white snake critter that she named Haku. Although unspecified, the difficulty level to acquire this monster companion is higher than the bear critter. It was presumably obtainable through a quest that was added in an earlier floor, which was shown under Kasumi's history. Acquiring this companion requires combat, wisdom, and discovery experience. Even after entering the Fog Valley in a Faraway Land, it was still a challenge for Kasumi.undefined

Other
More common monster companions make their appearance in NewWorld Online, although almost all of the details about them are still obscure and undisclosed.

Customization
With the release of the seventh floor, which included a new system that makes it possible so that all players are able to obtain a monster companion, the ability to customize the critter's appearance, as well as its skills or effects, became available.

Shortly after the twins acquired their bear companions, Iz was curious on what Mai and Yui was going to name the bears, and how they want to customize them. The former named her bear Tsukimi (ツキミ), modifying the color of its fur to become glossy black, and customized his skill effects to make it glow green. Yui chose the name Yukimi (ユキミ) for her bear. She changed the color of its fur to white, which makes it look like a polar bear, and customized its skills to make it glow pink.undefined

Trivia

 * Syrup is most likely a reference to the Spirit Turtle, which represents longevity. Oboro is likely a reference to the Fox Spirit, which symbolizes mischief.
 * Haku, Kasumi's white snake, is likely a mythical beast-tier monster companion. The level of difficulty required to obtain it is significantly higher than the bear. Its process of solo-ing is comparable to level of difficulty a group faces against a boss like Silverwing. It may also be related to
 * The four aforementioned Mythical Beasts may be based on the Four Symbols in Chinese mythology. The Black Tortoise, the Azure Dragon, the Vermillion Bird and White Tiger correctly corresponds to the turtle, the fox, the bird and the wolf.
