Bio-Belt

Physicist Ray Palmer used matter from a white dwarf star to create a belt which allowed the wearer to shrink to microscopic size, alter his mass at will, and maintains the wearer's normal strength. He could also shrink other objects, but they tend to explode after an hour. The Bio-Belt gave its wearer the ability to take any height from his full size on down through the subatomic. It also gave him the ability to assume any mass, any weight, and any density at any height, from his full mass on down.

The Bio-Belt was later revealed to be a product of Chronos' travels through time, though its location and time of origin have not been revealed. The belt used "matter-borrowing" worm-like creatures to operate. Both belts have since been destroyed.
