The Doctors, Heroes of the New Earth

It was a post-apocalyptic world.  Thick fog everywhere. The enemy was a cloak that ate things, it would cover something and make it disappear. I met with the group of heroes for the new earth that were super powerful and had superpowers. I couldn't remember what they were but they were the doctors I worked with and some coworkers. They wore this crazy armor with gold and cloth hats and stuff.
