After the White Event David Landers found himself dramatically and painfully gaining muscle mass. After being rushed to the hospital Landers met Randy O'Brien, a medical intern who had also gained powers from the White Event. The two eventually made their way to the Clinic for Paranormal Studies to begin treatment. When O'Brien was targeted by the clinic staff for his resistance to their brainwashing methods Landers and the rest of their treatment group fled the clinic with him. The clinic referred to their group as D.P. 7.
