Airhead (Earth-616)

Airhead was a young member of Trash. She may have been a mutant. It is implied that she was abused by her father. Airhead was the most compassionate of the group, and shared a special bond with her teammate Blasting Cap.

Airhead can inflate her head with expandable gasses that allow her to float like a hot air balloon. While her head is inflated, she can fly limited distances and speeds and carry tremendous weights, although there seems to be no limit upon the amount of time she may remain inflated.
