I decided to take the turaga from 2001 and combine them to create some new rahi builds. I went with the combinations I did, being Vakama/Whenua, Matau/Nuju, and Nokama/Onewa, because of the pattern in the 2004 Metrutoran mask swaps. My goal when I create rahi is to always include a kanohi somewhere on its body, and to incorporate a function that can be used for offense. These are the results.
For Vakama and Whenua, a woodpecker inspired rahi. This one has a pecking function.
Edit: It now goes by the name Kaipau. The Kaipau is a bird-like rahi inhabiting the charred forest on Mata Nui, using its drill beak to crack open rocks to hunt for bug rahi to eat. Due to the strength required to break stone, you do NOT want to be on the receiving end of a peck from this rahi.
For Matau and Nuju, it’s a rahi inspired more or less by an anteater. The function is in opposition to the previous build, with the band allowing it to quickly snap its head back up. Edit: It now goes by the name Tirihaka. The Tirihaka is an anteater-like rahi with quick reflexes. It lives in the icy regions of Ko-Wahi, adapted to hunt for prey beneath the ice, equipped with a metal, needle mouth for piercing through thick sheets of ice and snow. It often hits any predators that get too close repeatedly with their long, needle-like mouth.
And finally, for Nokama and Onewa, a dragonfly inspired rahi. This function uses both rubber bands, and mimics the way dragonflies slap their abdomens against open water.
Edit: It now goes by the name Kapowai. The Kapowai is a dragonfly-like rahi that lives between Le-Wahi and the open ocean off the coast. These rahi hunt for small fish, batting their tails against the water to lure the Ruki fish into leaping at them, only to be snagged by the Kapowai instead. This is one of the less common instances of two species of rahi preying on one-another in a two-way predator/prey relationship.
I have absolutely no idea how to convert a video file into a gif, I may update with a gif showing the functions in action at a later date.
Edit: Link to the youtube video for building instructions and demonstration of the functions. https://youtu.be/16IqhW_BpYw
