The Kanohi Kaukau is the Mask of Water Breathing.
Usually, only the toa of the water can swim well naturally. As this ice toa has a mask that would give him an advantage in an aquatic environment, I made him an adapted armor so that he could swim well too. That’s why he has “fins” along his body and what would be small turbines to propel him while swimming.
His weapon is the elemental double spear, one end freezes, and the other end heats up, serving to break the thick ice on the surface of frozen lakes.
I named him Kohga. I just joined the prefixes “ko” and “ga”, meaning ice and water from the Matoran language. Most likely I’ll change this name later on, but for now, I’m satisfied with it.
My own lore.
Kohga is quite playful and eccentric. Of the 4 ice mangai toas, he is by far the most talkative. when not on mission, he liked to test drive vehicles with matau in Le-metru or stargaze with nuju. During the fight against the kanohi dragon, he had freezed the elemental attacks of tuyet and naho to increase the damage of water type attacks on the dragon.
