–Clone Diclonii just before going on a rampage
The beings known as Clone Diclonii were born and bred at the Diclonius Research Institute.
In the manga
Doctor Nousou created four viable and fully usable clones of the late Mariko Kurama: Alicia, Barbara, Cynthia, and Diana. There were also other 1104 failed clones who possessed severe facial disfigurements and spent their lives in an underground dungeon in order to be harvested for organs, particularly their spinal columns (one of them has been killed off-screen for her heart to heal Diana), used to create vector-based weapons. Bred by Nousou at Chief Kakuzawa's orders, their heads were covered by cloth sacks, in order to hide their seemingly hideous appearance, with holes cut in various locations to grant them limited sight, with some of them having multiple eyes. Sensing Lucy and also of Arakawa's anti-Diclonius birth vaccine on the island, the deformed and abused clones finally rose up, killed almost all the remaining researchers and nearly destroyed the vaccine, turned back only briefly by the efforts and seeming self-sacrifice of the Agent.
Their vectors had wildly varying ranges and power. At one point they battled and killed their own 'sister', the viable clone Diana, whose mind control device caused her to fight them, holding them back for a short time. The damage caused by their rampage and Lucy's battle with Chief Kakuzawa, as well as bombardment by allied forces caused most of the island to sink, which finally put them out of their misery. They were a large threat due to their increased range and sheer numbers. The Kakuzawas never seemed to understand the irony of the harm they brought these girls, so much like the treatment of their ancestors by non-horned Humans.

- The depiction of their uprising resembles a zombie attack as seen in other media such as George Romero's 'Dead' movies and video games like Resident Evil.
- Being clones of Mariko, the Clone Diclonii were also the genetic children of Doctor Kurama and his late wife, Hiromi.
