General Melcrose is battle tested and is among the strongest Generals in the WAGMI military. She's experienced the worst atrocities while being a prisoner of war in an alien camp. Shortly after finding out, the Human Emperor and Talos took it upon themselves to rescue her from the prisons of planet Nibiru.
They found her unconscious and mangled. Shortly after, she was merged with cyborg technology made from NiFe. Her strength comes from the elemental power pink Adallium, an isotope, which is said to have been at the genesis of creation. She wants nothing more than to destroy the Gray Alliance and bring peace to the galaxy for all beings.
