In the Dark Mirror Universe, Nuju was a Ko-Matoran who joined the resistance against Tuyet. He was eventually killed by Sanox.

Dark Mirror
Nuju was a Ko-Matoran who joined a resistance team led by Pohatu with the goal to defeat Tuyet and remove her from power. During the battle between the Empire and the resistance, Nuju assisted Guardian in fending off a Toa of Magnetism, but was eventually dragged into the Metru Nui Archives by wild plants controlled by a Toa of Plant Life. The others assumed that Nuju was killed.

Dusk and Dawn
In Dusk and Dawn, it was revealed that Nuju managed to struggle against the plantlife long enough for its controller to be killed in battle by one of the other rebels. When Nuju regained consciousness, he wriggled out of the dead vines and heard a terrible scream. He followed the scream to see Sanox being transformed into a Toa of Shadow by the Kanohi Kraahkan. Sanox heard Nuju sneaking about and attacked him as a show of power. Nuju tried to escape, but Sanox hunted him down and restrained him with a Shadow Hand. In his last few moments before Sanox killed him, Nuju pondered why evil was winning, but remembered that there must always be dusk before dawn.
