Supergirl is a cousin to Superman. She is not quite as strong as he is, but she can levitate and fly at incredible speeds. Supergirl also wields powerful psychokinetic energies and can generate energy shields capable of cloaking her presence, effectively rendering her invisible. And due to the fluidity of her protomatter substance, Supergirl can also alter her appearance at will.
Legends of the Multi-Universe (Menslady's story)
