Screening of a large external charge in graphene is studied. The charge is assumed to be displaced away or smeared over a finite region of the graphene plane. The initial decay of the screened potential with distance is shown to follow the 3∕2 power. It gradually changes to the Coulomb law outside of a hypercritical core whose radius is proportional to the external charge.
