Mine is none other then my self-moc, Ranaki Pakewa. He is a "pseudo-toa" made by splicing together a Ta and a Le matoran, energizing them with toa-power, and using the spear of fusion to merge them into one being. This gives him limited dual elements of Fire and Air, which aren't quite as strong individually as a normal Toa's power. The fused minds give him higher mental functioning, which allows him the ability to use two Noble Kanohi or Kanoka powered equipment at the same time. His Kanohi is the Mask of Adaptation, allows him to physically adapt quickly to the local environment, current weather, and combat situations. He has quite a few special pieces of armor and gadgets that all use specially forged Kanoka Pellets as a power source, such as armor with integrated Regeneration, and universal antidotes powered by Remove Poison Kanoka Pellets. He also has a Kanoka Shotgun that he crafted himself, which he can load up with Kanoka Pellets, giving him the ability to use Kanoka, but with greater speed, accuracy, and ease. He has levitation disc devices built into his feet, propulsion-jets on his heels, and a jet-pack that he can focus his elemental powers into to give him boosts. Using the jets and levitation devices, he can boost his jumps to a degree close to flying. Add in his modified Air Katana/Kanoka Blades, he can add gliding to his boosted jumping, increasing his pseudo-flights distance. His "Kanoka Katana" have been forged using the same Kanoka combination required for the Mask of Conjuring, thus letting him speak powers into the blade.
Moral of the story, Kanoka are OP, and easily exploitable.
