Enmity is one of the seven cosmic beings known as the Seven Friendless, they are considered the children of Eternity. She is capable of changing her appearance, she has assumed the guise of a young frail blue-skinned child, and appears to enjoy creating animosity and mayhem. Through her own account she merged the minions of beings such as Annihilus, the Magus, Dormammu and many others. These beings offered up their energies, their devotions and their very lives to their masters and received nothing in return. She converted their pain, suffering and failures into one gestalt being, Unum, whom she set lose on the universe to continue her destiny of destruction. For unknown reasons Unum sought to rid the universe of its women heroes.
She targeted the women of the Lady Liberators and the female members of the Guardians of the Galaxy. Unum's battle against the She-Hulk and Jazinda was interrupted by the Elder of the Universe known as the Collector. Unbeknownst to both groups of women the Collector has whisked them to safety hoping that their collective powers would defeat the pawn of Enmity. However, without a true battle plan the women basically just fell over each other making their defeat inevitable. Had it not been for the quick thinking of the Celestial Madonna, Mantis, who led Gamora and She-Hulk in an attack that ended with Quasar impaling all the combatants. Mantis quickly entered the mind of Unum and She-Hulk was able to convince her that Enmity was using just as the others did, only she was doing for giggles and grins, which caused Unum to betray her creator, by impaling Enmity with her weapon. An enraged Enmity responded by apparently destroying Unum and teleporting away from the scene.
It has not been revealed if Unum's attack caused any injuries to Enmity due to her teleporting to parts unknown.
