Dr. Leonard Gade was the Invisible Man in the 40's from Timely/Marvel Comics. He was able to render himself invisible as the result of accidental exposure to certain chemicals in his lab. Gade was able to mentally bend light waves around him without creating any visible distortion.
For this character I started with a DC Direct Alan Scot Green Lantern body. The head is an Aquaman cast from Dead Man Customs. The cape is from a Marvel Legends Vision cape. Some minor Dremel work and some paint and then sealed with Testor Dul cote. I have included pictures of this character in both his visible and invisible forms. I hope you like them.
