Bionicle characters consist of the various species and races that exist in the fictional universe of Lego's franchise Bionicle.
The universe is mostly inhabited by beings with a skeletal and muscular structure, but metallic armor rather than skin. Most beings' skulls are bare, and they wear Kanohi Masks, of which some enable psychokinetic feats.
The Matoran are a race of small humanoid beings, and the most common inhabitants of their namesake universe. A few become Toa at some point in their lives; but in their natural state, their elemental energies manifest as minor physical enhancements, and they cannot activate the powers of Kanohi Masks. Though they are among the weakest races, they will fight to the last for their homes and lives, and are able to create fortresses, weapons, defense machines, and whatever other tools they need. The Matoran live by the principles of Unity, Duty, and Destiny. All Water, Lightning, & Psionics Matoran are female; all others, with the exception of Light and Shadow, are male. Both Light and Shadow are mix-gender. Light Matoran, more commonly known as Av-Matoran, can change the colour of their armour and channel power through their weapons. Certain Matoran such as Fe-Matoran of iron and De-Matoran of sonics, have been reduced in number by the Brotherhood of Makuta.
Notable Matoran include:
Toa are humanoid beings, each with power over his or her element, and the heroes and primary protagonists of BIONICLE. They were created as protectors of the Matoran race. Some Toa began life as such, while in other cases certain Matoran, using Toa Stones, transform into Toa. They serve as the public heroes of the Great Spirit Mata Nui and can wield the power of the elements. Teams of Toa typically consist of six members, each representing one of the main elements: Air, Water, Earth, Stone, Fire, Ice.
When a Toa fulfills his/her destiny, it may give up its power and join the Turaga: the elders that lead the Matoran. Their elemental powers are minimal and rarely used, but they can access the powers of weaker Noble Kanohi Masks.
Vakama, Nokama, Whenua, Nuju, Matau, and Onewa were released as the 2001 small sets. The Matoran Akhmou was released in 2004 as a first-wave small set; the form in which he appeared in the role of "Turaga" was never released as an actual set. Dume was available as part of the second-wave 2004 sets "Turaga Dume & Nivawk", and "Ultimate Dume". A Duracell exclusive figure depicting Lhikan in his Turaga form was released in 2006. Jovan was never released as a Turaga, but in the Lego Club's Official magazine, recipients were given the option to build his Toa form with pieces from Toa Inika Nuparu, Hewkii, and Hahli.
