Melynx are cat-like humanoids called Lynians, noted by their black fur and with the ability to talk in human language and do human activities like their fellow lynian subspecies called the Felynes. They are found both in human villages (such as Pokke Village) working for their human masters and living in the wild with their fellow Lynians.
Melynx in human villages sometimes take job opportunities, mostly as Felyne Chefs and/or Felyne Comrades. Felyne Chefs cook food for their customer to support them in their adventures by temporarily enhancing their abilities. Felyne Comrades assist their masters throughout quests with skills to make hunting easier and gather more items than usual.
Wild Melynx come in groups when not in their village. They wait for hunters to come by their place and become a victim of their thievery. When Melynx spot a human victim in their area, they begin charging to them and steal items. Once they obtain an item, they run away and dig underground, never to be encountered again (but rarely replaced by other Melynx). When a Melynx has been defeated while holding a stolen item, the item can be taken back by their victim. The Melynx then digs underground, defeated.
Some Melynx, when defeated, leave an sparkling item on the ground that can be picked up by the hunter. Their 'Secret Pouch' serves as an account item. Melynx keep their items inside their pouch and send their stolen items in their village. Hunters use a Felvine to distract Melynx due to their attraction to these plants. When carrying it, Felvine is the first item to be stolen by Melynx. It should also be noted that it is possible to take back stolen items. When stolen the items will be moved to the Melynx's camp and placed there, should the camp be searched any stolen items will be effectively taken back.
A warning though:If the place doesnt have a Melynx Camp,your items are gone.
They live in harmony with the lighter-toned species of Lynian, the Felynes. The Melynx and Felynes seem to be hostile towards the other Lynian Species, the Shakalaka, as they are never seen living in the same area together, though all three species live in the same environments.
