When Steve asked me to create Justo, I first went to work researching for the Justo suit. I got references of motocycle suits, Ironman, Halo, actual space suits, transformers and even Power Rangers for inspiration.
Steve wanted more of a celtic influence mixed with futuristic space knights. He wanted a medieval look and create something besides a gun. I created his suit to have circuits. I decided to have the circuits power his suit and also available for a weapon.
