Guards at Megakat Maximum Security Prison, serving under Warden Meece. Their job was to keep the prison’s inmates in check as well as to protect the facility from attack. Two guards, Talon and Lem, accompanied Rex Shard to the diamond mine to test out Dr. Greenbox’s Gemkat 6000. The others remained on duty at the prison, and defended it from Shard when he gained his crystal powers and came for revenge against Meece and Greenbox, however their laser guns were ineffective against him.
