Mortar appears with the Bastards of Evil which are the offspring of certain super villains. Mortar appears along with other villains like Aftershock, Singularity, Warhead and Ember where they wreck havoc in New York and attack innocent civilians for no apparent reason. She first confronted the newly arrived Nomad, telling her that her father was Grey Gargoyle. (Later revealed not being true) She went on to fight Firestar when an explosion interrupted them.
