Nighlok are monsters of the Netherworld. The Nighloks were led in the past by Serrator, unbeknownst to their current leader, Master Xandred. A Nighlok, as seen in The Team Unites, must be bathed in the Sanzu River or else they will dry up and start cracking to pieces. Nighloks appear to grow into their giant state upon their destruction without help from another villain. In this state, they are referred to as "Mega Monsters". When a Nighlok is destroyed, they end up in the Nighlok Heaven.
