Toa of Plantlife

Toa of Plantlife was a title given to a Toa who wielded the Element of Plantlife, and they were always transformed from Bo-Matoran. Should a Toa of Plantlife fulfill his destiny, they were given the option of sacrificing their power, becoming a Turaga of Plantlife.

If a Toa of any element were to lose their Kanohi, their elemental powers would be halved, and their overall strength greatly weakened.

Powers
A Toa of Plantlife's elemental powers gave them near-perfect command over photosynthetic life-forms. At a basic level, they could create, control, and absorb vegetation.

Examples of this included creating thorns and vines, altering the form of plants in an area, and controlling the actions of plantlife. Although unconfirmed, it is also likely that all Toa of Plantlife possessed an innate understanding of vegetation and plant toxins, and all these abilities would have been on a vastly greater level than a Turaga or Bo-Matoran's.

It is unknown if Toa of Plantlife could manipulate non-living wood.

Personality and Traits
As only one Toa of Plantlife has very briefly been seen in the main story, it is unknown what their personalities were generally like, although it's likely they would have been deeply in touch with nature, even more so than a Toa of Water.

Toa of Plantlife usually wore armor that was various shades of green, with blue acting as a secondary color.

All Toa of Plantlife were male.

History
Toa of Plantlife were rare in the Matoran Universe, with far fewer numbers than others, such as Fire, Air or Stone.

Only one Toa of Plantlife has been mentioned in the main story, and he was a member of Toa Lhikan's original team, the Toa Mangai. He fought alongside his Toa-brothers and sisters against the Kanohi Dragon in Metru Nui, some 4000 years before the Great Cataclysm.

The dragon had been freed from an icy prison by Reidak, Vezok and Avak as ordered by the Shadowed One, in an effort to coerce Turaga Dume into allowing the Dark Hunters access to Metru Nui. The Shadowed One's gambit failed however, when Dume refused the terms set down by the Piraka, in their master's stead. It was shortly after this refusal that the Toa Mangai arrived to fight off the beast.

The battle took nearly a month, so powerful the dragon was, but eventually the Toa Mangai of Plantlife and his allies culled the beast long enough to transport it to Xia, home of the Vortixx. When this transfer was complete, he returned with Lhikan to Metru Nui, and remained there as one of the city's permanent defenders.

It was shortly after this, that one of the two Toa Mangai of Water, Tuyet, went rogue, intending to use an ancient artifact, the Nui Stone, to absorb the powers of her teammates in an effort to destroy both the Brotherhood of Makuta and the Dark Hunters single-handedly. It is unknown what the Toa Mangai of Plantlife was doing during Tuyet's activities. She was subsequently thwarted by Lhikan and Nidhiki, and then imprisoned within an alternate dimension.

Later, when the Shadowed One launched an assault against Metru Nui, the Toa of Plantlife was present alongside his remaining Mangai allies in the Toa\Dark Hunter War. The war took place roughly 2000 years before the creation of the Toa Metru, and ended with the betrayal of Nidhiki, and a deal made with the Dark Hunters involving the Makoki Stone.

Sometime later, Makuta Teridax hired the Dark Hunters Eliminator, Krekka and Nidhiki to serve his interests within Metru Nui, whilst posing as Turaga Dume himself. He ordered the majority of the Toa Mangai to carry out various false missions beyond the city, leaving only Lhikan to remain behind.

One-by-one, Eliminator killed them all, including the Toa Mangai of Plantlife.

Over 1000 years later, the few remaining Toa of Plantlife evacuated to Spherus Magna, after the death of Teridax.
