Cloning

Eli (Heroes)
Eli has the ability to clone himself. Eli seems to be referred to by his clones as the "Omega" or the "Prime" and is able to produce hundreds of clones. All of Eli's clones are hollow on the inside and share a sort of collective mind. Eli's clones are able to travel vast distances away from the Prime, but they cannot stay away for long and feel the urge to return to him after a certain amount of time. They also possess no mind of their own and cannot be manipulated by telepathy though the real Eli can also disappear whenever they are taken out or the real Eli is knocked out.

Evan (Heroes)
Evan has the ability to clone himself, producing vast numbers of exact copies. These clones seem to grow out of his own body, in much the same way that Julien Dumont clones himself.

Julien Dumont (Heroes)
Julien has the ability to vegetatively clone himself, producing identical clones. Dumont appears to generate replicants through cellular mitosis, similar to a fungi. However, in Root and Branch, Part 3, a clone is clearly shown to grow out of Julien himself, much in the same way that Evan does in Revolutionary War, Part 2. Clones can be injured, even fatally, without causing physical harm to the root Dumont.

According to his assignment tracker file, Julien's control index is 90%. His data analysis shows his biological level at 95, cerebral at 50, elemental at 80, and temporal/spatial at 30.

Magdalena Muller
Magdalena Muller has the ability to self-duplication.
