A While back I played in a Bionicle Based TTRPG like D&D but all Bionicle themed. My Character was Whakatau Toa of Plant-life, the reluctant Leader of the New Toa Metru on Spherus Magna.

During the events of the main Bionicle storyline Whakatau was a Matoran living on the Southern Continent and witnessed to both events of the Island of Voya Nui getting launched into the sky and getting stuck up there, and then it's decent back down and rejoining with the Continent. Had he been any closer he could have ended up being one of the poor saps brainwashed by the Piraka or in Mahri Nui the coastal city that fell beneath the waves.

On Spherus Magna, prior to becoming a Toa, Whakatau was a part of a Matoran wilderness rescue crew living in the untamed outskirts of the city taking care of the forest and coming to the aid of Matoran who get lost or injured out in the wilderness who are often in difficult locations to get to. They can't always expect the Toa to help while they are busy fighting for the fate of the universe, so he and his crew were on duty to traverse the wilderness, get into difficult places that other people can't get to easily, and bring the matoran back or tending to their injuries. As a result he has learned to be very fast on his feet traversing over obstacles in his path and has medical knowledge. He felt more at home in the wilderness than in the city which has proven to be difficult for him to navigate because his parkour tactics has gotten him lost and stuck on top of skyscrapers more than once.

It was thanks to his exceptional skills in search and rescue that Whakatau was chosen to be the new Toa of Plantlife, his Hiking staff and Grappling hook transformed with him to become a Bo-Staff with a Grappling Claw at the end which he could shoot out towards a target in order to grab hold and then pull them to him or quickly zipp over to them. Having little to no social skills and feeling uncomfortable in the big city Whaka was slow to open up to his companions but was determined to use his skills to help them, even if he wouldn't be getting the most glory from it he could use his control of plant life to debilitate enemies and make them easier for the stronger members of the team to hit.

At the time the team included Whaka himself (The Medic) Keeps the rest of the team up while keeping the enemies down
Vaphi the Toa of Sonics (The Engineer) Builds the gear and machines
Vojakua the Toa of Plasma (The Blacksmith) Builds the weapons and armor
Parkur the Toa of Iron (The Muscle) Is the big guy with a really big sword who hits really hard
Koqunui the Toa of Ice (The Element Crafter) Is the one who's very good at using her elemental powers to make objects and structures
and Aruuko the Toa of Stone (The Veteran) Been a Toa longer than the rest of the team and knows the job

On their first mission they were tasked with dealing with some criminal activity in the city which turned out to be the work of the Dark Hunters. They managed to intercept a deal going on in a warehouse. Then things suddenly went very south as the Right-hand Lady in charge of the New Dark Hunters set off an explosion that killed Aruuko and Koqunui, and left Whakatau with a black burn scar on his mask. Following that mission Whakatau reluctantly decided to take on the role of Leader of the team in order to keep the rest of his companions safe, but he also developed a darker vindictive side especially towards all Dark Hunters. As a Toa he's not supposed to kill, but he started to grow a fondness for using his plants as torture devices, such as: Poison, Blinding Pollen, Acid, Stinging Needles, Burrowing thorny vines, and his signature torture method, a super Hot Pepper that deals Chemical Fire damage like Napalm which he appropriately named "The Makuta's Piss" (Inspired off of a cop I knew describing being Pepper Sprayed like being pissed in the face by the Devil!) And Whaka had a special exception for the Right hand leader of the Dark Hunters who he wanted to make suffer for the deaths of his companions before breaking the Toa Code and finishing her.

Whakatau's primary Kanohi is the Great Huna: Mask of Concealment allowing him to become invisible at will. Whakatau is a skirmisher, Healer, and the Utility Belt of the team; He is able to get around the battlefield quickly to keep his allies up, attack the enemies with quick powerful strikes before vanishing, and has a Plant for almost any situation or problem
