Iona is a gamma class scout, a synthetic AI from a machine world with a special harden nanite body, based on an epsilon class mining unit or "Eater". It can take an organic sample of a life form, extract that being's DNA, and turn itself into an almost perfect copy of that organic life. It can even project a signal that can fool even the most sophisticated of medical scanners - but for whatever reason, it cannot fool dogs.

It can also transform itself to produce simple weapons, or like its mining ancestor it could just swallow up its target, consuming it.

For reasons only known to itself, it often takes the form of Anna, a young white-haired girl, approximately 13 years old, the first human it was sent to copy (but not consume), the daughter of a military base officer. At some point, Iona befriended the girl, acting as Anna's not-so imaginary friend - and defender.

After its Alpha was destroyed, it has been operating independently. Classification: Rogue.
