Saiken first came into being in the waning days of the Sage of the Six Paths, who used his Creation of All Things ability to separate the Ten-Tails' chakra from its body and divide it into nine separate constructs in order to ensure that it would never resurface after his death. Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together even when separated, and that one day they would become one entity again with different names as well as forms than they did then when the time came for them to understand what true power is.

Saiken eventually fell into the possession of Kirigakure and was sealed into Utakata. In the anime, it was revealed that at some point before his appearance, Utakata's master, Harusame, tried and failed to remove Saiken from within Utakata, intending to save his student from being a living weapon for his village. Utakata, however, having not heard what his master had said to him, later came under the assumption after the incident that his master had tried to kill him. This failed removal resulted in Utakata transforming into Saiken and killing Harusame.

Though much has not been seen of Saiken's personality, the giant slug uses 'ore' (オレ) when referring to itself, 'ore' being a boastful way of saying 'I'. It also speaks with a dialect which may possibly be Ōsakaben.

Saiken resembles a large, white with a slight light blueish tint, bipedal slug with stubby arms and feet. It has two prominent optical tentacles (eyes) and hole-like openings as a mouth. Its entire body is covered in a slimy substance. During the last remaining days of the Sage of the Six Paths, Saiken was much smaller than its present-day self, but was still much larger than the Sage.

As a tailed beast, Saiken has a great amount of chakra and it is able to use it to create a Tailed Beast Ball. Saiken is able to emit corrosive, alkali substances that are extremely dangerous on contact in the form of a liquid or a gas, which was able to burn the skin of another tailed beast, such as Gyūki. The gaseous form was able to instantly disintegrate a tree that came into contact with it.
