On my quest to Comic Con 2014, I am not going to dress as this guy!
This is Augustus Freeman IV aka Arnus aka ICON
He is an alien a la Kal-El that came to Earth in 1839 and he was raised by African-American slaves. His ship conformed his appearance to look like the first life-form that discovered him. Unlike Superman, his world wasn't destroyed, and he's been stranded on Earth. He's was waiting until Earth's technology could allow him to return home.
Icon has an array of powers that rival those of the Man of Steel. In fact DC comics had a crossover and they fought. Although he is not as strong as Superman, Superman did comment about hard hard Icon hit him.
First Appearance Icon #1 (in Milestone Comics which later was merged into DC) and he was created in part by the late Dwayne McDuffie.
I found these pics online of someone that
already did a pretty good job with an Icon costume.
