Right off the bat i knew that i wanted to have a character that had a tactical look to him yet he still wore armor fit to fight super heroes, however we didn't want it to look like Major Marvelou's hard surface armor. I decided to give him a vest made out of kevlar plating along the line of Batman's armor in the Dark Knight series but i made it less apparent by giving him a trench coat to go over it this would replace the cape and hide some of his armor so he can catch his enemies off guard.
I looked at a lot of the bat family for references but I didn't just stop with Batman. I looked at the new generation of Robin, Night Wing, and Punisher iterations as well as other video game characters such as Chris Redfield whom has a very tactical look to him. I also referenced real life tactical vests, shoulder pads and trench coats to figure out how they would fit together.
After all of the research i felt like i was ready to start the iteration process. I took the tactical look of the vest and made an iteration depicting a character that was more of vigilante soldier than a super hero. The next iteration was on the opposite spectrum, it looked more like a super hero but the color choice made him look more metallic than kevlar and a lot of people got a Robocop meets Batman feel out of it, for the first two characters i made a version with a trench coat and one without. I eventually tried to find a middle ground between the two for the third concept.
Finally we decided that the gauntlets were not working with the tactical look and there was something off about the boots. For the next iteration I unified the kevlar vest, gave him full pants with knee pads and gave him padded gloves instead of metal gauntlets, i also added some detail on the trench coat to make it more interesting.
