When I built my Toa Nui I came up with two designs, but there weren’t enough pieces in the Toa Mata’s “piece-count” to do both. When I made the Toa Nui I limited myself to only using the pieces provided in one Toa Mata set. I planned to eventually make a “Omega Toa Nui” where I use extra pieces, and here it is.
Some cool things about the Omega Toa Nui is that I’ve used every piece from the Toa Mata set as well as extra pieces, and most of those extra pieces can be obtained from the Toa Mata. I Also was able to combine all six of the Toa Mata’s Weapons into one.
Here’s a picture of my regular “Toa Nui” so you can see the difference. And you can see the topic about it here.
I call this “The Staff of Protodermis” or “The Staff of Sealing”. It has the power to shoot a beam of energy and create a “Toa Seal”. The Toa Seal of the Toa Nui can only be unlocked if the individual in question knows what six elements were used to make the Toa Seal.
