A Prime Immotile from the Commonwealth Saga. Four motiles fuse together to create an immotile, going from mobile creatures to stationary ones tended by motiles. While Motiles possess the intelligence to perform some fairly complex tasks, they are not in of themselves self aware. In contrast Prime Immotiles (creatures which have a sizeable percentage of their body mass as brain) are, and indeed possess superhuman intelligence. They also contain the reproductive organs to produce the nucleiplasms which can form with base cells into new motiles. One immotile unit is smart on it's own, but they can also link up with other immotile units and intergrating it into their thought processes. The result is a Group Immotile with double the brain power, and new Immotile units can be added to it indefinitely. Old Immotiles units can be removed and replaced, allowing the group to grow and expand.
