Farfarello (meaning "Slanderer", or "elf", "goblin" or "evil spirit") was an improved species of the Hunter B.O.W.
History
The Farfarello was developed by the terrorist group Il Veltro by administering the "t-Abyss virus" to regular Hunters.
Attributes
As a result of being administered with the aquatic t-Abyss virus, Farfarello came to have aquatic characteristics such as the ability to mimic its surroundings and become transparent similar to a group of aquatic organisms. However, because it was exposed to multiple viruses (t-virus and t-Abyss), it became so aggressive that it was much more difficult to control than a regular Hunter.
Etymology
Farfarello is named after one of the 13 devils named the Malebranche (Evil Claws) from the Divine Comedy written by Dante Alighieri.
