Those inside were trapped to halt the spread of contamination, and their powers began to mutate—be they shapeshifters, pyromancers, or controllers of gravity itself—they all became known as the Needless. Adam Blade is one such Needless, possessing remarkable regenerative abilities and incredible strength.
