Year later he still worships Apocalypse and works together with his scribe, Ozymandias. He faked an identity of psychiatrist Dr. Heartly to convince Chamber to join the group, and abducted Chamber from his hospital bed to re-introduce him to the clan, as Chamber is the grandchild of Jack Starsmore, a former member of the Clan.
Frederick is also the father of deceased Generation X member Blink. After saving Jack Starsmore and Ozymandias during a battle with Dracula, Ozymandias thanked Frederick by sending a hooker called "Miss Ferguson" to him at night. They made love and apparently she got pregnant afterward and gave birth to Blink.
