Dazzler (X-Men)
When disco died, it kinda took the Dazzler's look with it. But Dazzler is one to change with the times, and adopted the popular early 80's Olivia Newton-John workout gear look. She also started hanging out less in discos and more with mutants, and joined the X-Men for many years.
This is another Dazzler custom done by my wife, Sarah.
