The Holobob.
Holobob was an ability introduced in Destroy All Humans!
Overview[]
The Holobob was a psychic hologram projector which easily fooled most Humans. Its general appearance was a ghostly shape of the person whom Crypto impersonated. In order to keep the Holobob maintained, it was required to use the Cortex Scan to replenish Crypto's Concentration. However, it had one flaw, Majestic agents had devices that were used to see through the disguise.
The ability was later deemed inferior to Body Snatch, due to its limitations as a holographic projector.
