In the Quest for the Four Great Lands, Firehead made a great amount of Grandeg's Robots obey him. He filled the containers with teleportation ammo, the same one used in Ziggo's Teleporting Gun. The robots then teleported the Matoran from the Four Great Lands to Firehead. Only one army was still obeying Grandeg, who used the army to protect the Temple of Gruissiono. Thousands of Grandeg's Robots were destroyed during the quest, but some remained. The remaining ones were shut down when Grandeg turned good again and escaped.
