Gregole is a type of Zoanoid developed by Cronos in the Guyver series. Amongst regular Zoanoids, this model is among the strongest. Its dense skin is comprised of soft tissue that can absorb physical impacts, making conventional weapons useless against it; it can also withstand high levels of heat and radiation. For offence, Gregole possesses a horn on its head which can deliver 6000 kg worth of kinetic force when Gregole charges enemies at full speed.
