He was revived by Jindrax and Toxica, who had fled from Viktor Adler (who had been disguising himself as Master Org) and had been searching for an ally. He then confronted Adler who had recently lost his powers and threw him off a cliff which apparently killed him (but also reawakened the real Master Org that Adler possessed inside).
Mandilok then accompanied Jindrax and Toxica back to the Nexus and assumed command over the Org forces. Jindrax and Toxica soon found that importance had diminished with Mandilok around and they were reduced to mere servants while Mandilok delighted in treating Duke Orgs like dirt. During his time in charge Mandilok managed to turn Animus against the Rangers which resulted in their Wild Zords being taken away however he was unable to follow through on this and the Rangers later got their Zords back.
Mandilok was furious that he had been so close to victory only to lose, and laid the blame directly on Jindrax and Toxica. When another Duke Org named Onikage arrived, Mandilok threw his full support behind the newcomer and was pleased when he took the initiative and kidnapped Princess Shayla. However it soon emerged that Onikage was actually working for Master Org who had been in hiding planning his return. Mandilok refused to bow to Master Org, only for Master Org to exact revenge for Adler's death by hitting him with a single but powerful blast which destroyed him.
Mandilok was soon revived by Master Org to guard the Nexus during the Org Heart ceremony. Mandilok, who was now completely loyal to Master Org, fought the Rangers alongisde Retinax and Nayzor however all three were destroyed by the Rangers. Although Mandilok was gone, some elements of his body (most notably the mouth on his chest) reappeared as part of Master Org's new body.
Mandilok used a giant fork and knife as weapons. These were used in the formation of the Nexus Blade. Mandilok could also breathe fire from the mouth with the male voice on his stomach and could also manipulate electricity with his hands.
Surprisingly, Highness Duke Org Rasetsu's hermaphrodite nature was actually kept in Wild Force.
