Here's the definitive designs for the Five Mythran of Crux, creators of Gallant V and the first Mythran to be born. Created by the Allfather Alnibus, the primeval First Builder, the Primaer. While they won't appear a whole lot in Our Universe, their role in there will be very important for the beginning of the series! As well as the role of the sixth of these guys. You'll see what I mean by that when the time comes. As you see, they also create a different weapon each using their Nexus Energy, as well as channel it to take different forms. Mythran can normally all do this, but these ones have it on a greater scale, especially when they combine their powers.
Amd yes, their names are based off the moderators from LU. Guess which one is which!
