In the game [[Rain World]], Iterators are sapient artificial intelligences running on semi-biological supercomputers of colossal scale (large enough to build cities on top of). Most often an Iterator is depicted through its "puppet": a [[humanoid robot]] connected to the hardware via an umbilical cable. Each Iterator's puppet has a characteristic design which includes [[colored skin|skin color]], a unique [[forehead mark]]. and various styles of [[robot ears]].

Five Iterators play significant roles in the events of the game:
* [[Looks to the Moon]]
* [[Sliver of Straw]]
* [[Five Pebbles]]
* [[No Significant Harassment]]
* [[Seven Red Suns]]

Consistently, Moon and Straw take female pronouns (and Moon self-identifies as "Big Sis Moon"), Five Pebbles and NSH take male pronouns, while Seven Red Suns takes neuter "they". The basis for this is unknown.
