A demiurge is a large fish formation seen in cosmic seas, it seems huge and intimidating to lesser beings, but can easily be defeated by someone who knows what they are doing. It may be closest to the fantasy creature "the bone dragon."

A barracuda is a large fish formation, positive or negative, it's 9 galaxies long and consists of many entities. Negative barracudas cannot recreate themselves and will only survive by leeching off planets which have life. It is the goal of evil beings to join a barracuda, thinking they will then be powerful enough to change reality and avoid karmic repayment. This idea is not new, it is very old and a standard evil plot. The evil beings are all living in separation from each other in their societies so they do not know this. Periodically an endtime event will play out where all barracudas, thinking themselves immortal galactic empire fit to rule everything, will declare war on each other. They will all see themselves as omnipotent and will mock all other barracudas, but they are all of equal strength. Through this event, they are all destroyed, and the sea is cleared - for a while.

Positive barracudas will have the ability to create a larger formation, this may be called a Cthulhu. This being has tentacles which are 9 galaxies long, and can consist of an undecided number of barracudas. This formation has so far never been defeated. Whoever sees the Cthulhu will escape, they will not pick a fight, and fearing that someone will know of their weakness, they will not talk of the experience.
