Genegarg is a kaiju from Ultraman Z, appearing as a monstrous threat in the series. It is not a human character, so it does not have a conventional personal first and last name. Genegarg serves as one of the dangerous enemy monsters encountered by the Ultra Heroes and defense forces, contributing to the show's action by attacking cities and forcing Ultraman Z into battle. Its role is primarily that of an adversarial creature rather than a named individual with a family identity.
