In the BIONICLE Universe, there were many beings who ruled, conquered, and served. The ones classified as non-Rahi species have several abilities, including the trait of speech, while others are regarded as unable to speak, otherwise known as Rahi. They were good, bad, traitorous, industrious and powerful.
These were species who are known to be intelligent, and generally have their own civilizations.
Matoran Universe
Matoran/Toa/Turaga
Matoran were the laborers of the universe, living in Metru Nui, Voya Nui, and the Bionicle Mainland just to name a few of many places. They are generally regarded as weak, but have the capability to transform into Toa. Since Matoran couldn't use Kanohi, they wore Powerless Great and Noble Kanohi. They had innate elemental powers. However, the Av-Matoran, Matoran of Light, and Shadow Matoran had the ability to channel their elemental powers to a certain extent, along with abilities that could only be activated by linking up to a Toa.
When certain Av-Matoran reach the end of their lifespan, they turn into Bohrok, mechanical creatures controlled by Krana meant to serve Mata Nui.
A Toa was a larger being that was formed when a destined Matoran brought a Toa Stone to a Suva (however, there have been other means of creating Toa). They had the ability to use the elemental powers that laid dormant inside them as Matoran and use their Kanohi masks, which were powerless as a Matoran. Almost every Toa carried weapons which they used for melee combat and to channel their elemental powers.
When a Toa achieved their destiny, they could give up their Toa power in order to become Turaga. Turaga were Matoran-sized elders who had weaker elemental powers and could use Noble Kanohi, weaker versions of the Great Kanohi they wore as a Toa. Each Turaga carried a Badge of Office, which was usually a transformed version of their Toa Tools.
Skakdi
The inhabitants of the island of Zakaz were brutal, traitorous, and usually very angry. They have organic spines and many different elemental powers. They were given these powers by a member of the Brotherhood of Makuta. The Piraka are Skakdi.
Vortixx
The inhabitants of Xia have a society dominated by females, as well as a deadly practice that forces partakers to climb a living mountain. Roodaka is a Vortixx.
While male Vortixx did exist, they were regarded very lowly, being given horrible jobs and almost no chance at getting better lives.
Zyglak
A savage, reptilian-like species, accidentally spawned from the remains of the Matoran making process, in which the Great Beings were trying to produce the first Krana instead. They were cast out, and left to nurse feelings of hatred towards all other species.
Makuta
Makuta were a species of beings created by Mata Nui, initially meant to create Rahi for the Matoran Universe. They were created about 100,000 years ago, using Antidermis from the Makuta Pool somewhere in the Southern Islands. All Makuta were members of the Brotherhood of Makuta, an evil organization lead by Teridax, formerly by Miserix. They are shapeshifters, but have evolved so that they have became nothing but gaseous entities. They need an armor to inhabit, or else their energy will dissipate within a few weeks.
Makuta controlled the element of Shadow and also had 42 other powers, which they could use to create Kraata. They could only inhabit robotic or non-living bodies. If a Makuta managed to absorb another living being into their essence, they would have to be able to destroy the mind of the being they had absorbed to live.
There are only two existing Makuta remaining in the Bionicle Universe: a Teridax from an alternate universe and Miserix.
Visorak
The Visorak were a species of spider-like creatures created by Makuta Mutran. Their venom had the power to transform Toa into mutant creatures known as Hordika, half-Toa, half-beast beings that were constantly struggling to retain their inner beast. Their venom would also affect others. Keetongu's species were the only known cure for Visorak venom.
There were seven breeds of Visorak: Vohtarak, Boggarak, Keelerak, Suukorak, Roporak, Oohnorak, and Kahgarak.
The Visorak were Rahi, but they are also proven to be an intelligent species.
Kraata
Kraata were sluglike creatures created out of Makuta esscence. They had one of many Makuta powers, as well as being able to infect Kanohi by touch, which forced the bearer to serve the will of Makuta. By immersing them in energized protodermis, a Kraata transformed into a Rahkshi, a suit of armor which could be controlled by a Kraata with the same power of the Kraata that was transformed.
A Kraata gained sentience as it developed through it's stages. A stage one Kraata only lived off of instinct, while a stage six was fully aware of it's mission, could withstand light, and had access to it's powers. Stage seven Kraata, also known as Shadow Kraata, were rare, as most Kraata developed to stage six.
One Kraata was exposed to the substance that transformed the Bohrok into Bohrok-Kal. This Kraata had sentience and was stronger than a normal Rahkshi. This being eventually joined the Dark Hunters, gaining the codename "Kraata-Kal".
Shadow Leeches were Kraata that were mutated. They had the power to drain a being's elemental and moral light, giving them power over Shadow. The Shadow Leeches died in the energy storms.
Kratana
Kratana were creatures created by the Order of Mata Nui. They had the ability to see into the past or future.
Their bodies had a Kraana's rigidness and a Kraata's long body. They attached themselves to a being's face and immediately activated their powers.
Spherus Magna
Vorox
The Vorox were once a species of intelligent beings known as the Sand Tribe on Spherus Magna, but years of nomadic wandering through the Bara Magnan deserts devolved them into primitive beasts. During the Core War, they fought for the Element Lord of Sand. They ended up on Bara Magna after The Shattering.
Some of the Vorox were on Bota Magna after the Shattering. These Vorox were able to keep their sentience due to the better living conditions. One such Vorox was Kabrua.
Skrall
The Skrall are a group of warriors once known as the Rock Tribe on Spherus Magna. In the Core War, they fought for the Element Lord of Rock. After the Shattering, the Skrall on Bara Magna were led by Tuma, the only remaining Leader Skrall. Only a few Skrall were ever named.
After Mata Nui defeated Tuma, the Skrall were forced out of Roxtus, travelling through the desert in groups.
At one time, the female Skrall gained Psionic powers and more intelligence. This led to them being shunned by the male Skrall. When the Skrall moved south due to Baterra attacks, the females were left to survive on their own. They eventually became known as the Sisters of the Skrall.
Agori
The Agori are beings about the size of a Matoran. They don't fight; they hire Glatorian to do that for them. Some of them sometimes fight in the Arena, but mainly as vehicle pilots. Not many Agori fight, but it was the disputes of their villages that started the Glatorian system. These matches between two village's Glatorian were started to prevent another war. The object of dispute went to the winner.
Zesk
The Zesk were once normal Agori-like creatures. After the Great Being's experimented with their genes, they gained stinger tails and were forced to walk on all fours. After the Shattering, the Zesk devolved into a species of ravaging beasts. They don't fight, but they can steal. Zesk speak a broken, primitive version of the Agori language.
Bone Hunters
The Bone Hunters are non-Agori nomads that live in the desert. They are affiliated with the Rock Tribe and raid desert caravans and sometimes villages. They all rode on Rock Steeds.
The Ice Agori Metus later convinced them to ally with the Skrall.
Great Beings
The Great Beings were very powerful, intelligent creators who were in charge of Spherus Magna. Eventually, they made the Element Lords so they wouldn't have to put up with the disputes of their planet's species. After the Core War, it is unknown where they went or what became of them.
The Great Beings had the urge to create.
