Rock Troll

This Dark Troll was sent to the surface by Koragg, and also given the Rangers combining power. With this power, the monster was able to grow and become a Golem creature. The Green, Yellow, Pink and Blue Rangers morphed into their Mystic Titan forms and tried to battle the Golem, but were no match. Luckily, they managed to release Nick from the dimension he was in, along with Catastros. Catastros then thanks Nick for healing him, by combining with the Mystic Phoenix to form the Centaurus Phoenix Megazord. This new Megazord was too powerful for the Golem to handle, and was destroyed by the Megazord's many fire attacks. Also, by destroying the Golem, the Rangers regained their combining power, but Catastros then returned to his master, Koragg.
