His company worked on the helmets and armor for films like Batman v Superman, Captain America: Civil War, Tron: Legacy and many more.
Watch the video interview below to know more about his design process and gaze at his marvelous collection of works, including that awesome Black Panther helmet.
Weirdly his company didn't get screen credit for Batman v Superman even though they designed the Batsuit, the Wonder Woman costume and the Batman Mech suit. (Come on WB!).
Fernandez talks about his early days of sculpting, how he got into the industry and how his current work involves designing things digitally while still doing traditional sculpting. His company lost the bid to work on X-Men: Apocalypse, but he still designed his interpretation for the character Apocalypse played by Oscar Isaac and it's definitely a better design with a more menacing look.
Here are some screencaps from the video:
