Nimrod the Scarlet Sentinel

Nimrod the Scarlet Sentinel was a lightning rod monster created from a stone fist statue by Lord Zedd. She had two effeminate looking male assistants named AC and DC. Nimrod was extremely powerful and the added strength of AC and DC made all three of them even more deadly. They were able to topple the Thunder Megazord, leaving the Rangers temporarily defeated. While normally the Thunder Megazord would have gotten up and finished them off with the Thunder Sabre, like against Robogoat and Stag Beetle, they had run out of energy due to the Command Center shutting down (as seen later in The Wedding). The Thunderzords were unable to continue battle, the Command Center being shut down caused a defficency of power. After Tommy gained the powers of the White Ranger, he was able to take on the monsters. Nimrod and her cohorts AC and DC were the first to face the new White Tigerzord and the first to be defeated by the Mega Tigerzord.
