Phoebe Deimos is genetically-engineered Martian bombshell who has been in hundreds of billion-dollar blockbuster movies. She has backing from the mob, who sunk a small fortune into creating her as part of a complex money-laundering scheme.
Outwardly a pleasant person, if a bit of a demanding diva, in private Phoebe is consumed with aggressive paranoia that her spot as number one is under threat. She suspects every cute young starlet as being as manipulative and scheming as she herself is, and tries to tear them down before they get to her first. To this end she comes up with elaborate plans to discredit or ruin them, but somehow these plans always end up backfiring on her in some way.
