Fiidora is the 6th disciple of Noah. He represents the "Corrosion" of Noah.
Like all Noah, in his Noah form Fiidora has dark skin and stigmata lining his forehead. He has light blue hair, the top layer cut in a bowl fashion while some on the back has been left long and drawn back into a ponytail that is held in place by several hair bands. He has a distinguishing pair of triangular earrings.
Nothing is known about Fiidora's past, but it seems that like the rest of the Noahs (except for Road, and the Earl), his previous incarnation was also killed by the 14th.
Seed of destruction arc
He is first seen greeting Wisely with the rest of the Noah Family, at his awakening of becaming a Noah. He later confronts Bookman, Lavi, and Chaozii in battle. During this battle, Fiidora infects Chaoji with his parasites and abducts Lavi and Bookman. Once the battle at the North American Black Order Headquarters ends, Sheril Kamelot meets with Fiidora. He explains to Bookman that they do not agree with the Millennium Earl's decision to bring the 14th to safety and he wishes to search the Bookman logs for information on him. In exchange, Lavi, who has also been infected by Fiidora's parasites, will be spared.
Fiidora has absolute command over all the Akuma, as well as destroying Innocence by simply touching it. All of his abilities, like other Noah, are based on Dark Matter. As a Noah, he is immune to the Akuma blood virus, which is normally fatal to the human's touch. These are the natural abilities of the Noah. He also have the individual power of the Parasitic Tongue, his tongue is covered in eyeball-like parasites that he can inject into multiple hosts at will. These parasites can be both volatile and benign, Sheril threatening bodily injury to Lavi using these parasites and Chaozii Han having one in his body that had previously been causing him pain currently going unnoticed. The parasites, in their benign form, can also be used for observational purposes, with Chaozii's body currently being used to spy on the Black Order while the Noah keep an eye out for Apocryphos.
