In Regice's cartoons,

When Glacia tried to open the desert ruins, Regice first appeared. With four iron dumbbells, the map stone fish of Safiya and Wailord, Dawu Zhiwoqi and Safiya opened the stone chambers where Regice, Regirock and Registeel lived. Regice used brute force to stop gurrado and Kyogre from trying to carry out large-scale destruction. After the war, the weak Big Three returned to the depths of the mountains and were captured by Brandon before the opening ceremony of the War Development Zone.

Brandon used Regice against me. Regice defeated Cora, who was borrowed by Miwan and belonged to Crystal, but was soon defeated by the iron tail sent by Miwan's lizard king.
