It's the Skrull with the base Fantastic Four's powers, the Super Skrull Kl'rt. This one was a taxing one to get together. Base is the standard Skrull Soldier from the Marvel Universe line. The rest is cobbled together from other MU figs - left arm is from Thing, left leg is Iceman's (to simulate Sue's invisibility powers), and the fire is from Ghost Rider's head. I also used part of the leg that I removed from him to simulate the stretching powers of Reed.
