Regirock's cry is a deep, grinding, and mechanical sound, resembling the heavy shifting of massive stone slabs colliding and scraping against each other. It has a rugged, reverberating tone, almost like an ancient golem awakening from dormancy, emphasizing its Rock-type nature and legendary status. The sound is somewhat fragmented, with abrupt, glitch-like distortions, giving it an eerie, artificial resonance, fitting for a Pokémon said to be constructed from prehistoric boulders.
