A Lot Of People Aren’t Fans Of Plasma As An Element. The Secondary Elements Have Very Few References

A lot of people aren’t fans of Plasma as an element. The secondary elements have very few references in the actual story of Bionicle, Plasma especially. Given its redundancy with Fire, it’s not hard to see why it was the most voted out element in this poll. I have a soft spot for it though, and not just because I have a story idea with a Toa of Plasma I’ve been rotating in my head for the better part of two years now… Anyway, I figured I’d take a go at coming up with a (metaphorical and literal) place for Plasma as an element so it's not just Fire+.

Su-Wahi is an expansive badland, inhospitable to most. Special care must be given when traveling; similar to Fire or Stone aligned regions, the heat is omnipresent, and water is scarce. Unique to Su-Wahi, however, is the radiation. Without preparations, spending too much time in the region will make travelers sick in a way normal medicine cannot cure. The most striking feature of Su-Wahi is the Sun. The massive light is embedded into the ceiling of the dome, similar to the Sun Holes of Metru Nui, but never dims.

Though much smaller and less impressive than any of the districts in Metru Nui, Su-Metru is the largest settlement in the region. The city is centered around its refineries and power plants, both literally and metaphorically. Six residential districts form a ring around the city, where the Matoran can live, relax, and sleep between their 6 hour shifts. These work days may be much shorter than what other Matoran are used to, but the work is dangerous, and mentally and physically taxing. The system was designed by the Turaga council to ensure that the plants and refineries were always staffed by well rested workers with clear heads. The central principle of Su-Metru is Responsibility, the synthesis of Duty and Unity. The knowledge that their negligence could lead to disaster weighs on the city's inhabitants constantly.

In the badlands of Su-Wahi, certain rare ores are mined and sent to the city, where they are processed, refined, and enriched, and then inserted into objects called cores. When power is applied to these cores, the enriched protodermis turns into ionized protodermis, which gives off tremendous amounts of heat. Inert cores are transported to reactors, where they are used to boil large amounts of water to spin turbines and create energy. 

The most powerful cores are sent to the largest reactor in the city, the Kaita Engine. In the heart of the city, twin rings, multiple mio in circumference, accelerate ionized protodermis. The two beams are directed into a central chamber where they collide and produce staggering amounts of energy. Curiously, the walls of the central chamber seem to then absorb the energy. The exact nature and origin of the Kaita Engine is only known to the Turaga council. Being allowed to work at the Kaita Engine is considered a great honor, and an even greater responsibility, as it is widely believed that the absorbed energy provides power to Mata Nui himself. Long ago, a series of accidents caused the Kaita Engine to be temporarily turned off. To the horror of the Su-Metru inhabitants, the sun itself began to go out. 

There are only a few settlements outside of Su-Metru, the majority of which are mining towns. In an obscure corner of the desert lies the Deep Vault, a massive construction patrolled by an especially surly group of Su-Matoran. Here, spent cores, radioactive waste, and other irradiated objects are contained deep underground. Giant stone spikes and walls cordon off the field, and massive signs warn off tresspasses, their messages repeated in Matoran, Skakdi, Vortixx, and Makuta. Nothing of value is buried here. This is not a place of honor.

While the ore used to create enriched protodermis is mined in Su-Wahi, the rare metals used to build cores and reactors are primarily imported from Earth and Iron aligned regions. The city also imports from Water and Ice regions for coolants for their reactors, and medicine that treats radiation sickness that is produced in the Green aligned regions is in high demand.

The primary export of Su-Metru are the enriched protodermis cores, the specialized containment cells used to store and shield them, and Su-Matoran operators. Ionized protodermis has a myriad of uses, but Su-Matorans refuse to sell powerful cores unless an engineer is also employed, to ensure they are used properly. Many cities and organizations have their own ionized protodermis reactors and employ Su-Matorans on a permanent basis to operate them. Other operators make regular trips to deliver fresh cores and transport spent ones back to Su-Wahi to be buried in the Deep Vault.

Given their dangerous cargo and important duty, traveling Su-Matoran are granted freedom of movement and are rarely accosted on their travels. Yes, that Su-Matoran could be carrying information from an enemy faction, but they could also be transporting radioactive material that could make everyone on your island sick if it gets into the ground water. Because of this, Su-Matoran are also employed as couriers and messengers. Traveling Su-Matoran need to be resourceful and prepared, and have more than a passing knowledge of first aid and medicine; some Su-Matoran choose to devote themselves to healing and become doctors. Species and elements of all types employ Su-Matoran as site managers due to their strict adherence to safety protocols, and though they have no special resistance to energized protodermis, and it has completely different properties than ionized protodermis, Su-Matoran are still the first ones contacted when it needs to be dealt with. 

Su-Matoran are serious, no-nonsense types with very little tolerance for tomfoolery. The hotheaded, rash Ta-Matoran put them on edge, and more than one Le and Po-Matoran have found their playful mischief has made them an enemy for life, no matter how many times they say “it was just a prank, brother.” Su-Matoran get along with the stoic and mature Ga, Ko, and Onu-Matoran, but are still unlikely to fully trust them. It’s not that they don’t want to trust them, it’s that they can’t afford to. Matoran of Lightning are the most likely to make true friends with Su-Matoran. They can bond over the dangerous work and responsibilities they share, and the Vo-Matoran’s optimism tempers the Su-Matoran’s pessimism. 

Becoming a Toa does not relieve their responsibilities, it just gives them new ones. Wielding elemental plasma is incredibly dangerous, and many have sworn off using their powers until they are trained by a more experienced Toa. Most Toa of Plasma join teams in pairs, one acting as a mentor to the other. Even experienced Toa prefer to work in teams with others of their element; they consider the redundancy a benefit and not a limitation. Of course, not all Toa of Plasma have the benefit of being trained by another of their kind… 

Another notable inhabitant of Su-Wahi is the local Makuta. Su-Matoran are resistant to the high amount of background radiation, but Rahi are not. The radiation causes mutations both in individuals and across generations in a way different than what energized protodermis, Visorak venom, or a certain Vortixx’s Rhotuka can create. The process has fascinated the local Makuta, and though technically they are assigned to the broader region, they spend much of their time in the badlands. Unlike others of their kind, the Makuta is sympathetic to the Matoran. They've spent centuries studying the awful effects radiation has on the body, and have stationed multiple Rahkshi of Quick Healing across the city to provide care should an accident occur. In the most extreme cases, heavily injured Matoran are transported to the Makuta’s lab to be treated. Eccentric and single-minded, other Makuta have written them off as a non-issue. They even survived Teridax’s coup of the Brotherhood and later take over of the universe, making them one of the last few Makuta left on Spherus Magna.
