Illusion (D20 Modern Skill)
From D&D Wiki
Illusion (Int; Trained Only; Power)
Check: Using this skill allows a character to appear as another person. The character appears as if under the effects of a Change Self spell except duration is determined by the check result. Creatures get a Will save to recognize the illusion if they interact with it, the DC for this save is equal to the check result. Even if they pierce the illusion the illusion does not end, they just don’t believe it.
